Magnacharged Goats, what are you running at the track?

[RedGoat]

I've read all these threads with Magnacharged Goats putting down over 400 rwhp, but not many that have run them at the track. I know there seems to be an issue with heat soak, and have heard some Magnacharged Goats are only running 100 mph or so in the quarter.

So to those with Magnuson blowers on your GTO, what have you run at the track?

[Georgia Goat]

I'm going to the track next Friday night and we will see. If the times that have been posted seem slow I would think it would be because of wheel spin. I know my car with the sc will light the tires at will and it wouldn't before the sc.

[mistermike]

Take some ice cubes. :D

Wheelspin can explain the poor e.t., but not the poor mph. I'd think with 400 hp at the wheels, blown goats should be trapping 110 mph on the low side and 115 mph on the high side. 100 mph is nowhere close.

[kick_*ss]

100 -Come on, I ran 103 - 13.5 in my 2k1 SS with just free mods and slp airbox. And my SS vert weighs about the same as a goat ( sad but true our goats more more like mooses )

This is the reason I got an A4 so I could fine tune the 1st to 2nd and 2nd to 3rd shifts. I can tell you that I know I will have to work on the launches ( wife too ). I accidentally broke lose going through an intersection just punching it to get out of the way of another car. Puppies just lit right up in 1st and 2nd.

I ran the virtual dragstrip and yes at 400+ rwhp with 3775 weight we "should" be able to hit 12.3 at 115mph.

Since I am not Kenny Bernstein or Don Prudhomme that aint gonna happen. I would like to just to break into the 12s on street tires and I would leave there happy.

Maybe in 2-3 years with new heads and cam 11s :D

You need to check that weight. My car with me in it checked in at 3855. Car with me (180lbs) and no spare, jack, or wheel chalks.

That seems in line with what other Magnacharged goats are running. Is it just me, or should 400-plus rwhp be good for more than 104 mph in the quarter?

we are having some issues with the heat soak.....I think there is more to be had, it will just take some fine tuning.

[nikivee]

Something is wrong for sure. I don't know what though.

[GTWhoa]

Something is wrong for sure. I don't know what though.

yep, I ran a 13.58@103 in my bone stock m6 last Sat. A S/C only giving you 2 tenths and 1 mph? Something is defintely wrong. I believe I can get a run in the 13.40's.

the best I did stock was 14.5's so I did gain a full second with the s/c.....I am not experienced on the strip.

Interesting that most every Magnacharged GTO (here in the US) is running about the same as the one I raced against at the track.

[mistermike]

Advice to Maggie owners at the track:

1. Install a manual fan switch. (pretty low tech stuff)
2. Remove the rear hood gasket, or get a PFYC hood
3. Consider a cooler thermostat
4. ICE CUBES!!!

[Georgia Goat]

My gto with me in it weighed 4180lbs. at the track. I am about 300lbs. myself. I didn't remove my spare tire either. I'm not making any excuses for my car. I'm very pleased with the maggie. I didn't by the car or the maggie to drag race. I just want a nice street car thats a little different than you can buy off the lot. I plan on doing more mods not for the drag strip, but because thats my hobby.

[dozlert]

Are you all running the stock injectors? I believe the stock injectors are 26 lbs/hr...is that good enough for the S/C?

[Wavydavy GTO]

Well, after a disappointing trip to the track two weeks ago I finally have some good news for Magnacharger owners. First off, the problem and resulting times two weeks ago.

Being in Florida, I waited until there was finally a night in the 60's to go to the track. I was fairly cool so I figured I could get some good times. WRONG! I made three runs, 13.0, 13.0, 13.2. My mph was only 107 or so. I autotapped one of my runs and noticed I only had 12.5* of timing at WOT and my AIT was in the 150's after sitting for an hour each time with a bag of ice on the s/c. I was pissed, $6k for 5 tenths?

I went to Mike Norris and we discussed what was happening and more importantly, how to fix it. Here is what we did.

Step One: Mike installed a relay on the intercooler pump and wired it to a toggle that went in that little rubber square behind the window controls. It is black and doesn't look out of place. I can now turn my pump on when the car is off to circulate the coolant through the s/c. It's the same principle as the fan switch.

Step Two: Mike gave me a AIT sensor he had laying around. I unplugged the AIT from the manifold and plugged it into the new onw which I zip tied to a small hose away from the engine. This way, when the hood is up it reads a much lower temp than the heat soaked manifold sensor. I will be getting an AIT extension so I can run it back up into the air box to read that temp. We discussed the possibility of added knock retard if the temp was too low compared to actual temps but decided to try it to see what happens. This will only be for track use.

Step Three (last resort): I bought a $3 siphon, bottle of Water Wetter, and a bag of ice on my way to the track. If one and two didn't work I was going to empty the resorvior (sp?) and fill it with ice.

So I was off. Last night the track was very cool by FL standards, about 68* with low humidity and a density altitude of about 400 which made it about sea level. Conditions were good. I didn't do the ice trick so I could see what the other things produced.

My first run was 12.636 @ 110 mph. Massive wheel hop but I still managed a 1.9 60'. Run # two was 12.663 @ 110. No wheel hop, just spinning tires but still a 1.9 60'. Run # three was 13.2 @ 109. My fault, wheel hop and spinning due to a poor launch. My last run was about 2 hours later with the car completely cooled down. It was 12.544 @ 111.94. I cut a 1.9 60' again but had a faster 1/8 than the other runs. Still a little wheel hop but not as bad as before.

Autotap showed my AIT's between 100 and 110 for each run. I did get a couple degrees of knock. The weird thing is my timing was still only 14 to 15 degrees at WOT and it should have been much higher even with a little knock. I'll get with Mike and see if we can figure it out.

All in all I'm extremely happy. I knew the car had a lot of power but it just couldn't get decent #'s at the track. I didn't try the ice last night because it was running good without it. I'll probably try it next time just to see if I pick up anything. I hope I didn't bore everyone touch much but I thought some of these mods could be useful.

I figure it this way. 6k for the s/c and I picked up 5 tenths, 6 dollars for a toggle switch and I picked up another 5 tenths. I'm going to buy more toggles switches, I can get into the tens for about $20, ha ha!

[gtodoug]

That is what I'm talking about!! Great runs. I too was a little discouraged to see some of times maggies were running.

[TprGTO-[Robo Fuzz]]

That is more in line of what I had expected from the s/c mod on these GTO's.

Nice report, Davy! Thank you.

Well, I have a maggie on my goat that tuned for elevation up here in Denver. My maggie is currently putting out 5lbs. of boost up here. Went to the dyno and she puts down right at 400 HP and 400 ft-lbs of torque. With the altitude at Bandimere being 6000ft, the car has run a best of 13.7 to 13.8 @ 103 to 104 MPH. The other Goats are running 14.99 and above, so yes I'm happy with my maggie. I know I've got the powere because the car produces terrible wheelhop and tirespin, along with sixty foot times. No matter how I launch, the best I can get out of the car is 2.162 sixty foot time, and YES, ALTITUDE SUCKS!!!!

[JCMGTO]

New times today. Ran at Atco, NJ and still learning to launch. But here ya go:

60' 2.011

1/8 8.353
MPH 87.72
990' 10.700
1/4 12.804

So getting better, still tuning a little and definatly still learning to launch. I know I need help there. Guy I ran cut a 1.96 60' and ran a 12.522. and almost identical MPH 111.48. Second gear also let loose on me. So just driving alone I know there is more in the car. Besides running on 18's with street tires:)

Dave I gotta meet up with you next time you go to the track, I know something is going on with mine, so far best is 13.25 @104. Now I need to make another trip to see Mike and get the same switch you have for the pump, sounds like it was worth it.

[bradyb]

What about just getting rid or clearing out the Magnuson intercooler and doing something else? That intercooler is pretty small and wouldn't it be better to just run a large frount mount intercooler? With the lower grill on the GTO you don't even need to cut anything to get an intercooler to fit? At Sema we were hot lapping our GTO for a good three hours and the intake temps never got above 65 degrees with our large front mount intercooler.
The GM engineers from Performance Engineering were talking about a GTO that was running 14.0 with the Magnuson SC. They almost had expected it to run that slow. They told us that with Magnuon's reduced sized intercooler the ECM was probably pulling out a ton of timing. Compared to the 6.0 L or the older LS1 the newer LS1 in the GTO really likes to pull timing quickly when it senses higher intake temps or heat soak.

[mistermike]

The issue is the heat exchanger in the manifold. They made it small for stock hood clearance. The FMIC is, in fact, so large to the point where it's beginning to interfere with engine cooling. Return H2O temps to the manifold are actually quite low, but there's not enough surface in the heat exchanger. The Magnuson Corvette kit uses a larger manifold heat exchanger and a smaller FMIC with better results. You could take any number of good C5 / Maggie runs, factor in the weight difference, and get an estimate of what the GTO might do with a different manifold.

[GTPprix]

Heres what I'm going to try to optimize my Magnacharger setup:
1. 160/170 Degree thermo. I know it's 50/50 on this one, but I can control the actual temp with the fan turn on points so Ill keep it around 180 ish and run another degree or so of timing.

2. I'm going to experiment with restricting the current to the pump to slow it down a tad to promote more time in the core and more heat transfer as a result. I'll put thermocouples in a few key spots to measure the change.

3. Dyno tune and some other odds and ends, but I think this may be enough to help out :)

1 and 3 sound good. 2 is a move backwards. Slowing down the water would only help if the problem was on the FMIC side, not the manifold side. Slowing down the air in the manifold would work, but it would be highly counterproductive to making power. If you measure the water temp on both sides of the manifold, I suspect you'll find that it's entering at pretty close to ambient. I think the real cure here is alcohol / water injection before the throttle. Padre and I have both been doing some research on the subject, and there are a couple of pretty sophisticated systems out there. Not only will it dramatically drop your intake temps, but some folks report slightly higher boost from the water forming a seal at the tips of the impeller blades. The Buick guys are old hands at this.

[GTPprix]

Well the reason I suggested #2 is because on the Grand Prix IC, with that same Bosch pump we didnt have enough time in the core for decent heat transfer, it was simply moving too fast to remove any decent amount of heat. We tried this same method and got an extra 15 degrees. Water injection would be great if it didnt strip the coating off the rotors, otherwise I'd be all over it :(

[stonebreaker]

You guys need to read up on heat transfer. You will not transfer more heat by pumping less coolant. You don't have little heat particle guys trying to jump into moving coolant cars and can't get in if they go too fast; It's more like a conveyor belt. The faster you run the coolant conveyor, the more heat btu's per minute it can carry away from the engine and dump to the ambient air. (If the pump is cavitating, you may have to slow it down in order to stop the cavitation; but that's a different problem all together.)

Also, you ideally want turbulent flow in order to break up any boundary layers in the intercooler tubes. Slowing down the coolant speed in the pipes is going to generate less turbulence, thus less heat transfer.

bradyb, you can't run a FMIC with a maggie. It compresses the air directly into the manifold. It's liquid intercooling or nothing. Well, I suppose you could hook up the air conditioning to pump freon somehow, but that sounds like more trouble than it's worth. Anyway, the heat exchanger for the intercooler is in the front, but the intercooler itself has to mount between the blower and the engine, and since the blower mounts directly to the manifold, there's only one place it can go.

[GTPprix]

Hey no clue on that one I was just going by what the guys at laminova told me and it seemed to work on that car lol There must be a way to fix this ;)

[stonebreaker]

Well it seems like the GTO intercooler just has too little surface area to pick up the required amount of heat. I'd think the next logical step would be to put the vette intercooler on it and see what happens. The alcohol injection seems like a good idea, too.

Does the maggie kit come with a true cold air intake? Seems like that might help things even with the small intercooler.

[Wavydavy GTO]

Last night the weather was great. It was in the 50's and the DA was in the negatives. For a change I got traction and no wheel hop (well, at least for my first two runs). Here are my latest, and greatest numbers:

Run 1- 12.360 @ 112.79 mph. 1.877 60 ft.

Run 2- 12.314 @ 113.10 mph. 1.848 60 ft.

Run 3- 12.773 @ 113.03 mph. 2.137 60 ft.

Can you tell which run I had wheel spin??? Even though I spun the mph was there. Now here is the weird one, on run 4 I was staged and was at about 1500 rpm just like the other runs. As the tree began to light up I threw a misfire code. As it went green I let off the brake and...nothing! I just sat there. I creaped forward enough to start the timer but I wasn't going anywhere. I let off the gas and hit it again and I took off like normal. I ended up with a 13.985 @ 111.59, with a 2.946 60'. I don't know what happened but the mph shows it recovered alright. I'm going to talk to Mike Norris about it, but right now I have no explanation.

So, with the exception of the last run I'm very happy with how the car did. I used the intercooler pump switch while staging and moved my IAT sensor again. I still haven't put ice in the intercooler resorvior because it was so cool out. I'm convinced that the increased coolant circulation and cooler intake ait readings are making all the difference. And now that I finally hooked up and didn't spin or hop I got 2 tenths and 2 mph compared to two weeks ago. The power is there guys, you just need to keep everything cool.

Thanks, I'll change it now. I would think so too about the climates but remember, for me, much of the year is a HOT and humid climate. Its like sucking in soup instead of air. Here I just work on it during the summer and have to wait until winter to see if it did any good.

[Fast GTO]

Yes, but for the $$ a Maggie costs you should be able to run consistent 12.5's even in the summer.

At least that is MHO.

[PadreGTO]

Congrats, Wavy. I might just have to head back to the track soon to make sure nobody catches me. :)

Make sure you share the knowledge with the other Maggie guys, because many of them aren't getting as nice results, even considering weather and altitude.

It only took them about an hour to install and the parts are very cheap. Its well worth it.

[mistermike]

Dave, I'm glad to see that the Maggie is coming alive for you. Good deal!

[Slowhawk]

The problem with Mag. supercharger's is the serious heat soak on the run.A dyno tune for the most HP does not help.You will find the car will pull timing going down the track dropping a ton of power.On the real cold day's your car will run better because the intake temp is lower due to the intercooler working alittle better.When it is tuned on the dyno you have to set AF to 10.5-1 and drop timing 1-2 degree's from your high HP run.This WILL give you better track times :) Dyno's mean nothing in a forced induction car :banghead:

[dcbingaman]

According to Magnuson, the C5's are not impacted by the heat soak problem to like the Goat's are. Question, has anyone bit the bullet and put a C5 Maggie on a Goat, and modified the hood to fit ? Are there any commercially available fiberglass hoods that will allow the C5 Maggie to fit on the Goat and save weight ? How about a plexiglass bump insert for the stock hood, so the world can see just how crazy you really are, (ala Ferrari) ??

It's not just the slightly smaller intercooler core but the airflow through the heat exchanger out front. I don't think changing to the Vette core will have a huge effect. People are working on getting Maggie equipped GTO's to perform at the drags using several different approaches. I think this will all be sorted out in time.

[kick_*ss]

This maggie goat is just running in place :(
Figured, WTF anyone can go down the strip fast, I like to just sit and burn my tires clean off.

[mistermike]

The PFYC hood supposedly will clear a C5 setup. The new Maggie for the CTS-v also uses the same manifold as the Vette. The FMIC on the GTO is actually too big, to the point where airflow to the engine radiator is affected. Water temps coming back from the FMIC are plenty low enough, but the manifold just can't transfer enough heat. Another thread just started on alky/water injection. This is probably going to wind up being the most effective approach with the GTO setup.

[tittermary]

for 5000-6000k the damn car should run 11's period!, you guys are nicer then me. I would be blowing something up.

If heat soak is a problem then use a 50 shot as an intercooler for the track, seems like u guys are happy with the on the road performance but at the track the things are dogs? I am I on target here?

anyway good luck and hope you solve the problems and has anyone who knows what they are doing really tuned any of these cars with LS1 edit or Hp Tuners yet?

[stonebreaker]

Are you guys using a cold air intake for the maggie?

[Slowhawk]

The Mag can run fast if tuned right.This means -not dyno tuned but street/track tuned.
We have a customer running the Mag on a 01 Silverado shortbed 4.8 liter.The truck runs 12.4 at 114mph -4800lb race weight.The tune had to be done at the track since it ran like crap with a tune done on the dyno(13.2 at 98mph).

so the tune that comes with the mag is **** then?? all that money for a half ass job sounds like to me.

I know the Mag works in other cars but in the GTO as far as I can tell its junk so far... not trying to upset anyone I am sure it work out but damn talk about beta testing :banghead:

I lucked out and having someone from ls1tech review and getting the maggie running perfect.

So far he has my SS purring like a kitten after 2 flashes a few more and its going to be one hellaova beast. Have to flash the GTO with his tune now and if its anthing like he did for the SS its going to be a HUGE difference. Ever see a cam'ed ls1 idle at 800rpm without stalling or surging? heck he even has my iac sitting at 45 without touching the t/b.

This guy rocks and is even teaching me how to tune the RIGHT WAY :D

And yes once I have this tune I will post it for the maggie folks :D

I only have ls1edit and efilive's flashscan as soon as its released, January 3rd.

What sort of exhaust do you run with the Maggie?

.

[kick_*ss]

right now stock. once I get my core charges back for the t/b's and maf ends from jantzer performance I will be getting a set of headers and exhaust that flows better, most likely the slp set for the gtos. The stock exhaust is just to quiet, although you sure can hear the s/c whining :D

The AED hood is being built specifically with the maggie in mind. It will clear with no problems and also has special ports to help with the heat soak problem and generally help keep our LS1's cooler all the way around.

Another thing is if you're getting belt slippage, which I know driveshaft driven setups are more prone to, is to use VHT track bite on the belts as it is extremely sticky and all but eliminates belt slippage. I've seen this work on eaton 03 cobras and KB cobras with very good results. Just a thought...

[Screwed Goat]

Moose Juice!!!!!! Ask pro renagade/5.0/ect.. racers what that is..... That helps in the belt slipage department.

Talked to Magna Charger Friday and was told the GTO testing was going very well. I was told that they picked up 40 rwhp and was able to control the IAT temps much better. Some quick testing at a local airport showed mid 12s at 115 with no traction at all. I was told that they actually made more HP on the GTO than they ever had on a stock C5 Corvette. The GTO was up from 422 to 460 rwhp and 455 torque on the same 6-7 lbs of boost. They would not say at this moment exactly what they did, and did not say how they were going to handle the people that allready have GTO kits but said it was all being reviewed and would be handled. I can not wait to find out what they did thats like a second and a half off the time and over 10 mph faster. WOW

who did you speak with? I certainly hope they offer something to the people who already paid $7,000.

Would water/alcohol injection help to reduce the intake charge temp, and possibly help to reduce heat soak?

I talked with Magnuson Monday the 24th and they confirmed what Goatanator said above. They told me to send them my programer and they would send me the new tune and some other parts with instructions on how to install them. I spoke with them on Friday to make sure they recieved my programer. They said I should have it back in about a week. I'll let ya'll know how it turns out. It looks like Magnuson is stepping up to the plate and standing behind their product.

There is a new fuel rail cross over tube and a new tune. They didn't mention any other new parts. He said the fuel was getting too hot by the time you hit 3rd gear and the new tube addresses the problem.

I'm waiting for the instructions to be updates before they ship mine.

Did you have to re install the stock tune before returning the programmer to Magnuson or does the new tune overlay the old tune as installed?

[GOATANATOR]

No you can just overwrite the tune that is in it, I think they use HP Tuners to tune so if you had HP they could just E mail you the BIN file. I guess someone with a 402 and AFR heads and cam ran a 11.10 @ 127 at Las Vegas with a GTO with a maggie on it that is almost as fast as some of the corvette guys. But I just heard this by the grapevine so who knows if it is true. Also I guess the front license plate kills the airflow to the intercooler and needs to be removed for increased airflow. Magna Charger said that they can not tell you to do that exept for off road use. I guess the feds don't like that one.

thats great but doesnt mean shit to the people that never have had a front plate.....so the theory does not hold water, my car JUST got to a 12.9 @110 after adding exhaust cut-outs...

So what is the deal? Is maggie coming up with a fix for what they screwed up on the original?

I hope they get these kits to get a GTO across the line in the mid 12's, I would expect nothing less for the 7K.

They have my email address and ZIPPO from them.

Going to send email asking about this. But truthfully, I trust the guy helping me more, he has the goat running better then the install shop or magnuson ever did.

[edit]
I did however send an email after going to the track with their tune, and asking "WTF" its running +20s LEAN, and that I expected MUCH BETTER after spending an additional $300 for a special tune that was pretty much as bad as the shops crappy tune. I GOT NOTHING BACK

[kick_*ss]

JUST SEND TO MAGNUSON:

Hello

I purchased a Magnacharger, and later the A4 tune from you. After going to the track and logging the runs found it to be dangerously LEAN. LTFT were reaching +20 through most of the runs.

I have learned on the ls1gto.com sites forum that there “may” be a new tuner and tune.

First, is that true? Second, how do I get my tune updated?

I am pretty disappointed with the tune after spending $300 for something that “may” have damaged my engine. Obviously without tearing down the engine I won’t know.

Could someone please address this?

Thank You.

Hey kick SS I had a aftermarket MAF on my car and it ran real lean with the mag tune and I put the stock meter back on without the screen and my LTs are -5 to +8 depending on how hot it is and my WOT AFR is 11.8-12.1 so maybe your ported MAF has not been reflowed and the transfer fuction data is off. did you try it with you stock meter? How much timing are you running? My mag cal was defaulting to the low Octane table for some reason and I only had 13 deg now I have it locked at 20 deg with no IAT correction untill 170 IAT and its a whole new animal. I am pulling at least 112 in the quarter. the G-Tech says 12.7 at 114 but I do not know how accurate that is the g-tech said 13.8 at 103 with the original mag tune. I just cant get any traction and I already need new tires, the cords are hanging out. Magna Charger had the 6 speed cal done and was working on the auto and said about a week or two and they will notify the owners.

[REDGLOW360]

Heres an idea I got from the tech that put mine in, he said to get the c-5s intercooler and use that, the only problem is hood clearance which means getting a new one. I got the c-5 intercooler for free and there are enough hoods to choose from that u can probably find something, I think theres even a couple that have both a RAM air set up and engine bay air exchange vents. Gonna give it a try and see how it goes, kind of a costly solution but it works on a couple of lvls.

[kick_*ss]

I am using a ported maf since thats what magnuson said to use which freed up almost 40rwhp.
I would "ASSUME" that since they made that recommendation for a descreened/ported maf they would have tuned for it. BIG ASSUMPTION :D

I am already looking to get the AED GTO hood for the Magnacharger. My wife loved the way the AED hood looked, so selling off all the stock parts and my SS's stock parts to be able to get that.

Like I said above, I am just checking since I am already getting it tuned by someone that knows how to tune for FI cars. Tuning for NO MAF should be removing the MAF frequency problems. I have to keep it on, since stupid NC has inspections and no MAF triggers an emmisions code.
So for 2 weeks out of the year I will run the crappy tune with MAF, get inspected, then put the good tune back on. Its what I do now for my SS ;) Lean the hell out of it to pass inspection, get all the emmissions tests completed, get inspected, then back to a good performance tune. This year I may even opt to remove the cats and run the straight pipes after I get inspected. :D

You missed the time when they 1st came out and fell flat on there faces.

Everyone was looking for answers and trying different things to find the problem.

Magnacharger added a fuel cross over tube at the front fuel rail and changed the provided tune. They were suggestions of license plates, Ported MAF's non working IC's.
Cars would Dyno 400/400 then run that same time at the track as they did stock.

This thread is starting now make me think twice about the maggie, I have $8000 in hand ready to hand off to Mike at Haddad for a 112hh install!!! I spoke also with brian(JPA) yesterday and he said this heat soack issue is a bunch of bologne, our car's have a-lot of heat issues no matter what FI system you put in!!!So results will be similar with any other system!?????????

So I guess my Question is is the maggie worth it or NOT!!! I am not looking to drag my car but use it for auto-X/canyon carving fun!

U guys with procharger's- what are you running in the 1/4 with what kind of boost psi??( let's not start comparing a 7psi maggie with a 10psi D-1 system)

Also Brian had said that" there iat sensor is located in the hottest part of the intake path so that the computer reads the true temp of air mixing with fuel, and by moving it around your asking for trouble" he a assured me that magnusen has done a-lot of reasearch into these unit's and not to worry b-cause these are very dependable system's that make great power! But i agree with all of you, for 6500 bucks I would expect better than a 1 second gain in the 1/4 mile???????

IMO go for the Maggie! I am bias because I have one but I've had other systems and for the money and reliabilty you just cant beat it. I've beaten cars with much more horse than mine because the roots system makes power so quick the other systems cant catch up. the top end units like turbo's and prochargers make nice HP numbers but are not as fun as the Maggie and while they're working on theirs your gonna be driving yours.

Ok , I have calmed down a bit and givin Mike the go ahead!!Schould have unit by end of next week and install the following!

I need help on one more issue though, Mike said an LS7 clutch schould work, but I'm a bit concerned that it will not hold up to long. I know it works with the 500 HP LS7 but I will be at like 515-540 rwhp! Don't know were to go from here??

Spec 3+ or spec's twin disk?
textrilia?????
Mc Leod twin disk?
Please help I would like to have somthing with a similar pedal feel as stock, maybe something that that will be easy to break in!

I was planning on waiting a few month's for the maggie but the tune for the header's was gonna b a waist of $500 so might as well just maggie her now and tune only once!!!!!

[LS2 tiger]

If you can afford it go for the Tex. I did and havnt had any problems. The 2.7 pulley from pulley boys will give you the boost you need. If you want more boost you will have to do a rear pulley change or a crank pulley. IMHO keep the car reliable and be kind to your bottom end,go with a 2.7 and a good clutch. Save the big money for tires axels and driveshaft.

I'm A4 so I can't really help with your clutch questions

[lanceygto]

IMO if you guys want to add more boost by a pulley swap then you should optimize your move with a blower cam. Duration, lift and no overlap would give you optimized performance results with a lower pulley. You have to put that boost to work other than just pushing on your heads.

It is unavoidable. You get a Maggie, sooner or later you will lower the pulley ratio and do a blower cam pushing 8 psi. That is where it is at. Meth helps cool things down under such conditions. As much as I was restraining myself for going Meth I found it unavoidable as well.

You see, it all goes like this: First, you get a GTO. Second, FI could make it go faster, which it does. Third, after a while you feel about the FI just like you felt about N/A: I can make it go faster by optimizing, which is true. In terms of power, anything else after that you are a lost case.

then installed the maggie and a set of DR's ran 12.12 consistantly @ 112-113 60ft went down to 1.85 I think it has more.. I also installed a set of koni adjustable shocks. I have the time slips to prove it if anyone wants to see them. The best part is I am in montana and the density alltitude was at 7200 ft. we data logged all my runs and there is more to improve on. If anyone wants the nuimber to my tuner let me know. I havn't been beat by another maggie blown car yet. Oh ya its only at 5lbs of boost :)

With my setup first time to the track on stock everyday driving tires. My best run was 12.09@120mph.

That is with mp112, 1:1, 2.9, 10psi and a custom EDC cam.

[7008ccGTO]

I was disappointed with first runs too. Ran 13.5's. My problem turned out to be a slipping belt. Changed to a 1.5" shorter belt and went 12.8x's. Getting used to launching with the added power took it to 12.6x's. Track temp was 84 deg. These runs were on 245 width street radials, so lots of wheel spin too.

[nesikachad]

This is by no means accurate.

My car tugged at 479 on the wheels.

I measured a quarter mile on a county road and did some runs. MPH was between 110 and 118. I guess this sounds about right then considering what the 400 rwhp cars are getting.

Thoughts?

[nesikachad]

Traction was/is a joke by the way. My 60's are timed with an egg timer.

[MEAN GTO]

Last I was dyno'd (.1" larger blower pulley and a slipping belt) I only put down 465 rwhp. This was done on Mickey Thompson drag radials and a 3200 stall converter, in warm, Florida weather. I'm sure I'm putting around 480 rwhp or so now, maybe more if I'm lucky.

Best time so far has been 11.180 @ 120.xx mph with a 1.53x 60' in some fairly cool weather. Only weight reduction was removing the spare tire and jack. No meth nor nitrous.

those times are a little more like it. i've been reading this thread and all I see are 60 ft times, 2.0, 1.9, and people getting excited about 1.8's. if you want to run fast in the 1/4 with these cars get it off the line! 1.6 60fts shouldn't be so much of a problem with the torque these cars make. get the rubber out back and the right suspension and drive it.

I'm originally a mustang guy so when i see crazy torque and over 400whp and 1.8 60fts i wonder what's going on. i know these cars are heavier but 450+ rwhp and the torque the maggie makes is enough to get these heavy beasts moving
