Procharger Owners - Please Step Inside...

Had great results with the Vortech V1 S-trim on my 98 GT before I got the Goat. I miss having a power adder. Now I'm seriously considering a Procharger for my 05 M6, but for my technical concerns I have not found sufficient data by searching here in the FI forums, nor from ATI's website (trust me - I spent six hours scouring this past weekend!) :bomb: Hopefully this thread will help!

My goal for the car is to be able to run 11s on drag radials and trap 120...without sacrificing drivability and without resorting to a fully built motor. 525-550whp on stock cam would be pure sex!

Current mods are in my sig line. :turbonaug

That being said...I have the following questions for those of you who own a Procharged GTO. Please take some time to answer them to the best of your abilities as your feedback will solidify my decision on a 8psi D1SC kit from EPP.

You may PM me if you don't want to post openly in the forums. :popcorn2: I will be grateful to anyone who is willing to help me out. Thanks in advance!

1) What does your setup consist of, especially boost level and supporting mods?

2) How long (in time and miles driven) have you had your ATI kit installed?

3) What issues, if any, have you had thus far?

4) How was the install (if you did it yourself)...any pieces not go on as designed or intended?

5) Are you pleased with the power delivery, where the boost comes on, etc.? Are you pleased with the low-speed response (<2500rpm)?

6) In your opinion, are the stock gears sufficient for drivability with the centrifugal power or do you feel that a deeper gear set (3.73-3.91) would be of great benefit for street and track performance to get the motor up into its power band quicker?

7) Has your head unit had any leaks or issues?

8) Have you monitored your IATs in warm weather to check for heatsoak, or have you compared temps (even by hand) of your discharge tube (after blower, before IC) to the temp of your inlet tube (after IC)? I am concerned about the heat soak reistance of an A-A setup.

9) Are you pleased with the fit, finish, and performance of the kit overall?

10) If you were going to redo the buildup on your car, would you still run the Procharger? What, if anything, would you do differently?

Feel free to post up track times and dyno graphs, especially those of you with stock, internally unmolested motors! Also please specifiy if you are an A4 or M6.

Thank you much! -mcs

1. Bought the 7psi kit, but did headers and full exhaust so im running 4.5 psi.

2. 2200 miles.

3. Oil coming out of the dipstick under WOT.... fixed by relocating the vacuum lines. Biggest issue with the install is that procharger's tuner messed up my PCM and my car would not start. I had to have it towed to the shop to have them sort out the tune. I still have a service engine soon warning every time i start the car.

4. Took me 12 hours to install and i would say im very good with cars and engines. Directions aren't great. Procharger customer service was wonderful!!!!

5. Being that i did all the mods at once the power is extreme. Very smooth and once you get up to 100mph its a different car. Power is instant from idle to redline but grows with the rpms.

6. Gears would just make you blow the tires even more on a street car. I love the way it drives.

7. Not at all.

8. The dyno shop did. They recommend the snow kit.

9. The maggie looks much better under the hood. The maggie kit looks like it came from the factory. The procharger fit is very tight and the finish.....not really all that.

10. No, its cool and it made the car run great. I think for the power level I would of went with a built motor...cam, heads, pistons etc.

Only mods: SLP Long tube headers with cats, Bassani cat back, Procharger Kit, and a custom tune.

490 rwhp 430 rwtq

M6 sorry i forgot that.

And come down to San Antonio, i'll give you a ride.

For 1/4 mile times, check out this '05 GTO.

Hey mcs! Congratulations on your consideration for the purchase of a D-1SC Procharger kit. :)

1) I purchased the D-1SC 7psi kit from Bob at EPP. And a Lingenfelter GT2-3 sleeper camshaft , Comp springs, pushrods, etc.. Stainless Works long tube headers and ’05 Magnaflow catback, 60# Mototron injectors and did the 255lb/hr Walbro pump in the 8.1L truck fuel bucket. Fluidamper balancer needed because the stocker is junk when trying to stack another pulley on top of it (I would strongly recommend this purchase!) EFILive purchased to be able to tune SD myself.

2) It’s been on the car for 2 ½ years and about 6500 miles.

3) I had some induction tubing on the drivers side that was hanging lower than I would like it to be, would still like to get some made out of aluminum to lighten the weight. The other issue I had was the idler/tensioner pulley spindle needed to be shimmed to allow for proper belt alignment.

4) The install was a pain in some areas, mainly in the induction tubing routing and support, and the PS reservoir relocating bracket was junk, I made my own. I think ATI has cleaned up the kit for the ’05 cars from what I’ve seen. Heath’s car looked cleaner than mine in this regard!

5) The power delivery comes on basically like the car did when stock, below 2500 rpm, above that and it comes to life!

6) In my opinion for driveability, I’d leave the gears alone. If you plan to put on taller drag tires, then gears would be a good choice, although not for daily driver..

7) No issues at all with the head unit, 2 oil changes so far.

8) No, but this is an experiment I want to get to this summer.

9) Very pleased with the fit and finish other than the half-assed routing of the induction tubing. And the install looks very OEM, and that’s the look I wanted.

10) If I were to redo my car, I would probably be happy with heads and a bigger cam, because 540rwhp/470rwtq is more power than I need, and 7 passes on the strip with the tires spinning half way down the track proved that. Of course, my technique needs help. And it’s a lot of weight to add over the front wheels where you really don’t need it in a drag car.

let bob at epp put his procharger kit in and the tune is included. he does great work. look at the epp sponser site.

First off I was once sort of in the same boat you were at one time, I was tossing it up between APS TT or Procharger. I had always wanted a procharger back in my f-body days espcially watching some of Exotic Performance Plus's Monster builds and the awsome numbers that were acheived. The decision was easy and Bob and Jake and the rest of the crew @ EPP took care of me and of course my car. I was very pleased with the outcome and reliability of my car. I didnt have any problems other then the big T word TRACTION!! Here were the specs on my car to answer your questions

My setup was 06 D1SC kit @7 psi with a epp blower cam and kooks headers with no cats and magnaflow mufflers. This setup produced 570rwhp with methonal which I will talk about when we get to the IAT.

I drove my car alot , almost too much it was just too much FUN! I had about 7k miles within a 6 month spand which was crazy!

Only issue I had was traction and drive train holding up , I spit my driveshaft(on street tires) on the highway one night acting silly with my friend who has a 04 GTO. I know alot of guys have had problems with axles and axle stubs and some guys have had no problems. Though the procharger itself gave me no problems, also to mention no engine lights no stalls no nothing , I belive Brent @ EPP has the tuning on these things down to a science!

Install was great and as stated up top the tune is also in my book a BIG part of the install. Now on prochargers end Iam not crazy about the filter route and I belive the piping could have been alittle more made to fit in the intercooler routing , however it is nothing bad the the filter can be run different , if you look at Heaths install and EPP's site they have a good write up on his install showing this modification they did, Bob also sent you a link to his car , showing Heaths awsome 1/4 times.

Yeah low end I was surprised because alot guys said that it doesnt seem to shine until higher rpm , Though low end was very stout and top end was insane , I know the cam really helped the low end out alot but I always thought is was missing one piece , dont get me wrong it had plenty of power but I just wasnt happy with the gearing.

Thats when I swaped in the 3.91's and the car was just a animal after that. It really went well with the D1SC and just drove like a completely different car , though this didnt help with traction but seem to make the car much more fun to drive.

Yes the good ole heat soak , I live in Indiana and some hot humid days are just a joke and heat soak does take into affect but the methonal really helped this out ALOT with the IAT's, I didnt have a very fancy kit and it was worth the money imo.

No leaks at all on my headunit

All and all I was more then pleased but like any car guy everyone always wants more POWER! My new setup I wanted to stick with Procharger since it has more then proven itself to me. I will be running the F1C with a forged 402 ,edelbrock wcch 245cc heads, custom intercooler and piping etc, which is currently @ EPP

Hope this helps

Cody

Oh....SNAP! Cody - Bob just told me about your car yesterday. 'We have a customer who is upgrading to a built 402 for ore bost with an F1A head unit to obtain 800whp'. Friggin sweet that you happened to chime in on this discussion!

This is GREAT info! I can see already that despite being what some people perceive to be 'low' on the TQ #s, these ATI kits have no trouble destroying tires. I was surprised to hear how it split your Cody - were you wheelhopping when the fatality happened, or was it just a stress-break from torque and tractions? Wheelhop usually kills parts on these cars.

Sykb47 I would LOVE to make a trip down to see your car and get a ride in it! Your numbers are great for only 4-5psi...loks like you still have a LOT left in it. Have you not wanted to pulley it back down to get the 7-8psi 530whp level?

It is also interesting that so many of you have stated you would go all motor since that is the other route I have always considered, especialy because it can be done sequentially in stages, and not an all at once investment like the ATI. This is not a 'which is better' peeing match. I would simply like to hear you guys elaborate on why you would prefer a cam and heads setup - did you mean INSTEAD OF or IN ADDITION TO the ATI?...

Thank you ALL who have contributed thus far.

1.) I have a good bit more mods, but these are the "power" mods and those to support it...
Engine:
ATI P1SC1 Procharger at 9.5psi
ATI Race Bypass Vlv
Reichard Racing 3.40 blower pulley
ET-Performance boost check valve
Custom CAI
Fluidampner balancer
Futral Motorsports FM7 blower CAM
Patriot Gold XTreme dual springs and retainers
Comp chromoly pushrods
Fuel:
60lb Mototron flowmatched injectors
LPE intank pump upgrade
Alkycontrol Meth Injection kit (pure meth)
Exhaust:
Kooks COATED 1 7/8" LT headers w/ off-road mid pipes
Magnaflow Catback
Drivetrain:
LS7 clutch kit
GMM Race shifter

2.)On the car since 1900 miles (currently at 34,xxx). Over 2 years. This is my daily driver. Currently getting about 16/25 mpg.

3.)Was initially sent a faulty head unit from ATI. Failed after 400 miles. Rebuilt and sent back. Fine for over a year. Started whining more than it should. Sent back again. Rebuilt. So far no issues at all. ATI customer service has been GREAT!! Even when out of the 1 year warranty they took care of me.

4.)A buddy of mine and I did it over a weekend. It was his second go-around at it. We also did the Fluidampnr and pinned the crank when we installed it (I knew I was going to be looking to run more than 7psi). I HIGHLY recommend you, and anyone else, do the same when doing the Procharger. Few things needed "adjustment"/"modification" but nothing extreme.

5.)I am pleased with the way the power delivery comes on…now. Below 2500 is basically just like stock. With just the kit (pre CAM, meth, and LT’s) the car didn’t really have much below 4k. Now the car makes power much lower and through the mid-range where I wanted it most. I’ll post up my latest graph so you can see how nice the torque is. One thing you have to accept is that Centrifiguls are linear increasing power adders. The more rpms, the more power it makes. So not as much down low, but they scream on the high end.

One note: I highly recommend ordering the D1 kit as opposed to the P1 kit. Granted, the P1 kit can make some power, :), but with the D1 you have more room to grow. And you don't have to push it as hard to make the same power.

6.)Gears? No way. At least not for me. It’ll already light em’ up easily. I see no need whatsoever for shorter gears. I get through the stock ones fast enough as it is, lol.

7.)Refer back to #3

8.)Air to Air is a great street setup. Esp. for daily driving (as mine is). Temps are noticeably cooler after the IC. Even on hot days (and we get plenty of them here). That being said, intake temps can still get pretty high in the summer. I was seeing 130’s-150’s if I remember correctly after a handful of runs on the dyno. Now once the meth kit was installed it made a WORLD of difference. What would normally be 130’s is now more like high 90’s. Put it this way, with just the kit I was making 489/443. Once I installed the meth, CAM, and LT’s I went to 640/547. Change of boost was minimal (went from just under 9psi to 9.5psi…3.55 to a 3.40 pulley to maintain boost).

9.)Overall I am pleased with the kits fit and finish. It looks clean under the hood imo. Am I pleased with the performance of the kit? Uh, yeah, but…see #10 below.

10.)I would probably go with the APS TT kit if I had to do all over again. Why? For one, I’m a turbo guy. Always have been. Only reason I didn’t do APS first was b/c back when I did the ATI kit the APS kits were still 9000-10000 bucks (when they first came out)! It wasn’t until 4-6 months later that their prices started coming down. However, that being said, the ATI kit has been great. Makes lots of power and I have had nare an issue since putting the kit on the car. One big plus to me is the fact that the ATI kit uses a SELF CONTAINED head unit. Seeing as how my head unit went bad on me and was filled with metal chunks/slivers, what would have happened had it been getting fed from the motor?? Possible engine damage?? In the end it’s a great kit and I’d recommend it to anyone.

And most importantly, if you go with the ATI kit, BUY FROM BOB AT EPP!!! Great guy and company to do business with!!!

Thank you ALL who have contributed thus far.

Yeah iam actually going to run the F1C its a lilttle bigger then the F1A , hopefully we can get 900+rwhp , the combo is going to be alittle unique I think it will make great power! I also maybe pulling the trigger on a solid rear axle , Trackday has a sick setup that iam drooling over! Though if I were you I would buy the kit first and go from there,. You might decide later how far you want to take the HP. The cam is an excellent compliment but with out having forged internals 500-600rwhp is about limits on stock internals and when it comes time to or if you wanted a forged motor the D1SC makes awsome power.

Nice Clean setup BBGTO!

http://www.youtube.com/watch?v=1pSpYYylt7c

vid of my car with old setup but gives you a good idea of sound on the epp blower cam

I have had the D1SC kit on the car for two years and 6K miles with basically zero problems. I just had my car at EPP for their blower cam and a tune. I could not be happier with the results. 590/512 and then backed down a little to be 100% safe.

The car ran consistent 11.80's at 119 last weekend without speed shifting and somewhat "easy" launches.

PM me your phone # and I can shed some light on common issues etc.

Jeff

Jeff, how easy were you taking it on the car (i.e. launches, shifting, etc.)? Seems like, if nothing else, your trap would be a good bit higher with 590/512.

Nice Clean setup BBGTO!

Thanks! I try. I'm one anal SOB, lol.

Bob I told you you are a popular guy on here! How far is Indiana from Austin?... Dare I ask

Cody I just made the connection after watching your youtube vid - I have watched your two vids INCESSANTLY since I first found them two months ago! How cool to finally get to chat with you.

I would love to have the EPP blower cam even if I were staying N/A! Question for you - was it cold in the night time vid you made or was that a warm idle for the cam? I ask because it still had a muscular nice lump, yet all the other 115LSA cams I have hear sound like stockers with no lope. Thoughts? I really want the lope if I am going to invest in a cam.

Barbados Blue your numbers are intimidating! Do you think the stock motor will continue to hold? I would love to have 600whp and your power curve is perfect...just worry about my stock shortblock that I can't afford to replace.

Has anyone here blown dipsticks from boost pressure in the crankcase? I have a nice catch can that is supposed to help provide a ventilation space, no?

Keep the feedback coming thanks guys! -mcs

My car a 04 A4 with a 3200 stall, when I had an LS1 with D-1SC it made 555rwhp can't remember tq but it was like 500tq. I also have a cam in it, but it wasn't a FI cam, it was na cam TR224 and some slp headers with some LS6 ported heads. Car has ran 11.4x with mid 500hp at the track with 122-125mph, and only 1.7x 60' times. Now I have a different setup I don't have a LS1 I have a forged 408, with ETP 245 heads and a custom Flowtech Cam. Car is only make 630rwhp and like 560rwtq, i haven't had it the track yet though. I am going to change the D-1SC though as this blower is not even giving my engine a work out. Going with a F-1A.

Yes it sounds like that warmed up as well , Lol makes me sick hearing it and not having it but it will be well worth the wait , this is a very expensive hobby but I love it! Yeah Iam actually going to EPP this friday to check on my car and takes my buddys GTO to get tuned.

I never had any problems with my dipstick

600rwhp would be my limit with the proper tuning and fuel of course. Just the idea of a bad tank of gas :bomb:

I think you might as well start truckin that car this way to good ole Indiana and let Bob work his Magic! lol

I have a couple times but then i went with a catch can and problem solved, also i blew my ls1 with 550+ plus hp but I didn't have any methanol for safety and i just got a bad tank of gas in there.

Bumpedy bump! - anyone else?...

Perhaps a Question 11: Have you blown or damaged your factory LS2 with a Procharger setup...if so, what went wrong?...

1) What does your setup consist of, especially boost level and supporting mods?

2) How long (in time and miles driven) have you had your ATI kit installed?

3) What issues, if any, have you had thus far?

4) How was the install (if you did it yourself)...any pieces not go on as designed or intended?

5) Are you pleased with the power delivery, where the boost comes on, etc.? Are you pleased with the low-speed response (<2500rpm)?

6) In your opinion, are the stock gears sufficient for drivability with the centrifugal power or do you feel that a deeper gear set (3.73-3.91) would be of great benefit for street and track performance to get the motor up into its power band quicker?

7) Has your head unit had any leaks or issues?

8) Have you monitored your IATs in warm weather to check for heatsoak, or have you compared temps (even by hand) of your discharge tube (after blower, before IC) to the temp of your inlet tube (after IC)? I am concerned about the heat soak reistance of an A-A setup.

9) Are you pleased with the fit, finish, and performance of the kit overall?

10) If you were going to redo the buildup on your car, would you still run the Procharger? What, if anything, would you do differently?[/b]

3. No major issues, the bearing in the tensioner sounds to be shot, and time to time makes a loud noise(like belt squeal)

4. Install was easy, and fun too. Would def love to do another one.

5. Yes, I am making 400 ftlb of torque at 2500rpm :turbonaug


6. higher gears would be nice, however not for a DD

7. Some very very minor leaks, however I have been told it is okay and nothing to be concerned over.


8. I do not monitor my temps.


9. Indeed. Tight fit, but it all makes it in there, lol.


10. If I could have afforded it, I would have gone twin turbo. I don't look back a single second at my decision, I love the SEG I get from the procharger.

Just let me know if you are ever in town.

I plan on getting a smaller pulley to bring the kit back up to 7psi. Before i do i will i'll get the methanol kit and upgrade the clutch, driveshaft, rear, stubs, and axles.

let bob at epp put his procharger kit in and the tune is included. he does great work. look at the epp sponser site.

Thanks, I appreciate it! Bob

First off I was once sort of in the same boat you were at one time, I was tossing it up between APS TT or Procharger. I had always wanted a procharger back in my f-body days espcially watching some of Exotic Performance Plus's Monster builds and the awsome numbers that were acheived. The decision was easy and Bob and Jake and the rest of the crew @ EPP took care of me and of course my car. I was very pleased with the outcome and reliability of my car. I didnt have any problems other then the big T word TRACTION!! Here were the specs on my car to answer your questions

My setup was 06 D1SC kit @7 psi with a epp blower cam and kooks headers with no cats and magnaflow mufflers. This setup produced 570rwhp with methonal which I will talk about when we get to the IAT.

I drove my car alot , almost too much it was just too much FUN! I had about 7k miles within a 6 month spand which was crazy!

Only issue I had was traction and drive train holding up , I spit my driveshaft(on street tires) on the highway one night acting silly with my friend who has a 04 GTO. I know alot of guys have had problems with axles and axle stubs and some guys have had no problems. Though the procharger itself gave me no problems, also to mention no engine lights no stalls no nothing , I belive Brent @ EPP has the tuning on these things down to a science!

Install was great and as stated up top the tune is also in my book a BIG part of the install. Now on prochargers end Iam not crazy about the filter route and I belive the piping could have been alittle more made to fit in the intercooler routing , however it is nothing bad the the filter can be run different , if you look at Heaths install and EPP's site they have a good write up on his install showing this modification they did, Bob also sent you a link to his car , showing Heaths awsome 1/4 times.

Yeah low end I was surprised because alot guys said that it doesnt seem to shine until higher rpm , Though low end was very stout and top end was insane , I know the cam really helped the low end out alot but I always thought is was missing one piece , dont get me wrong it had plenty of power but I just wasnt happy with the gearing.

Thats when I swaped in the 3.91's and the car was just a animal after that. It really went well with the D1SC and just drove like a completely different car , though this didnt help with traction but seem to make the car much more fun to drive.

Yes the good ole heat soak , I live in Indiana and some hot humid days are just a joke and heat soak does take into affect but the methonal really helped this out ALOT with the IAT's, I didnt have a very fancy kit and it was worth the money imo.

No leaks at all on my headunit

All and all I was more then pleased but like any car guy everyone always wants more POWER! My new setup I wanted to stick with Procharger since it has more then proven itself to me. I will be running the F1C with a forged 402 ,edelbrock wcch 245cc heads, custom intercooler and piping etc, which is currently @ EPP

Hope this helps

Cody

Thanks Cody, I appreciate your input. Bob

Bob I told you you are a popular guy on here! How far is Indiana from Austin?... Dare I ask

Cody I just made the connection after watching your youtube vid - I have watched your two vids INCESSANTLY since I first found them two months ago! How cool to finally get to chat with you.

I would love to have the EPP blower cam even if I were staying N/A! Question for you - was it cold in the night time vid you made or was that a warm idle for the cam? I ask because it still had a muscular nice lump, yet all the other 115LSA cams I have hear sound like stockers with no lope. Thoughts? I really want the lope if I am going to invest in a cam.

Barbados Blue your numbers are intimidating! Do you think the stock motor will continue to hold? I would love to have 600whp and your power curve is perfect...just worry about my stock shortblock that I can't afford to replace.

Has anyone here blown dipsticks from boost pressure in the crankcase? I have a nice catch can that is supposed to help provide a ventilation space, no?

Keep the feedback coming thanks guys! -mcs


19 hours and five minutes, depending on whether that first stop light by you is green or not. lol

LS2/402 with unported AFR 225 heads, our blower cam and 14.4 psi of boost from an ATI ProCharger F-1A with GTO bracket system. 93 octane with a methanol injection kit.
Check out the torque at 2300 rpm! Bob

well its official.. i pulled the trigger... after all the debate i chose a d1sc procharger.... aem gauges, meth, hp tuners, 3 bar(speed density) in addition to my 1 3/4 kooks lt's, and hi-flo cats, intake and spintech catback .....hopefully it will all be going together in the next couple weeks....im ecstatic to say the least

question is, what should i be able to do with this setup against a2004 c5 zo6 w/ a d1 .....and a 2005 6.0 gto w/ sts (60mil)and meth

these are sum of the ppl im sure to run once its all done ... curious about the turnout and how or setups should stack up ..oh btw i got drag bags in the mail as well ....thanx in advance ....my goals are about the same as the OP's goals (so no hijacking here) lol

The 'vette will beat you because of the weight difference alone - you need about 125-150rwhp advantage to make up for the 550 lb difference. (Especially if you're going from a dig because the 'vette has so much of a traction advantage against the GTO). The GTO will be much closer but I still think he might beat you. His peak hp will be about the same as yours but his boost will kick in sooner. Nothing that a driver mod couldn't handle though...

edit: This is assuming of course that the cars are stock with the exception of the mods listed, and that all 3 cars are tuned for optimal power.

All depends. How much are each putting down?

All depends. How much are each putting down?

well in that case, with my (full lt's, hi-flows and spintech) dropping my boost to 4-5 psi, if i advance the timing can i get up to 7-8psi equivalent whp via meth....i want to be safe cuz elevation here is like 4000 ft. .. im no expert so guide me if this isnt quite right ..

if this approach, could get me 550-575whp in my goat safely vs. the sts goat with 520whp .. then i should have the advantage, correct.

Me and this guy are good friends so i wont be too hurt if i loose.

All depends. How much are each putting down?

Agree. Also, the lighter weight of the Vette sometimes is a disadvantage on the street from a dig. I've proven that more then a few times.

yeah i caught up to a c5 zo6 wit a 6lb whipple and w/ the help of 295 DR's he still couldnt catch the traction train to save his life... from a dig he wasnt really walkin as hard as i was expecting, and i just have boltons right now...but once he let off and got sum wheel speed up .. .. umm yeah it was a wrap for me lol lol lol

Hijacker!!! Focus on me people!

Just kiddin. I am interested to hear how you like your setup. Please PM me in a couple of weeks after yo have it all tuned and dialed in, or dig this thread up and post updates here.

Good luck Brav! -mcs

My goal for the car is to be able to run 11s on drag radials and trap 120...without sacrificing drivability and without resorting to a fully built motor. 525-550whp on stock cam would be pure sex!


Too many words for me to read, but you'll still lose to someone at any track meet we put together :) Good luck though on any FI route you go.

didn't mean to steal the focus lol ......i think were both after the same goal so this info should benefit the both of us ....i will definitely pm u the results ... im beginning to contemplate a shorter pulley as well tho. IM afraid that the pulley along wit the meth may b too much for the stock compression :confused:

what size pulley, and what is your elevation?

what size pulley, and what is your elevation?

I'm going to be getting tuned in Tucson AZ... but am stationed in NM, Alamogordo... the elevation here is like 4300ft so i know when i get back from AZ I'm gonna be a lil rich..How much for a 4" pulley and will i blow up installing this pulley with the meth on advanced timing..on stock compression? just looking to get the best bang for buck, safely :popcorn2:

I live here in Phoenix. I am running a 4" pulley, methanol, and about a 9.3:1 compression, and about 17 degrees of timing. No motor carnage yet :popcorn2:

if I'm not mistaken, ur lowered compression is more than likely ur saving grace..... dropping my compression, however is not in the budget as of yet....!

317 heads should do it for you :turbonaug

they can be had for like $200 bucks off of a truck forum like www.performancetrucks.net (if your on ls1tech, your same user information can be used to log on there as well since they are sister sites)

so wuts the stock heads, like 245 err sumthing.. so wuts the compression difference changing them out for 317... and how much boost could i run safely with meth and exhaust :popcorn2:
