Track results.

[TprGTO-[Robo Fuzz]]

Well the temp was 86, and altitude is 1300 feet. I made two runs, 1st was stock setting, then I programmed in the Predator.
1st run stock=14.10@98.93. .228 R/T.
2nd run Predator=13.89@102.7 .410 R/T
I am very dissapointed that I did not get mid to low 13's. No excuses, T/C was off, 3rd gear. The consolation for me was that many people told me the track was running at least a 1/2 second slower than usual. There was a black M6 GTO from MD that ran 15.10 and 14.7. He told me the track is about a second behind, and he has a stock M6. Two STI's ran 15.6 and 14.9.

Nah, don't be disappointed. Stock, the best I could manage with the same weather and similar altitude was a 14.2.

But the 102.7 traps mean you're putting 320+hp to the wheels and your Predator gained you 30+hp at the wheels. :eek:

That's pretty friggin awesome if you ask me. So :drink: .

What were your 60's?

So... (Any 60 ft. times?)
14.10@98.93 for you without Predator
13.89@102.7 for you with the Predator (.21 seconds quicker & 3.77 MPH)
15.10@? for the M6
14.70@? for the M6
15.60@? for an STI
14.90@? for the other STI

Either with or without the Predator, and corrected or not, guess who was King of the Hill here... :D Technically, the Predator was worth .21 seconds if everything else had been equal. The 1/2 or 1 second off normal was probably due to the lack of track preparation for T&T. All things considered, I'll take .21 seconds for $350.00 and not even getting my hands dirty! :thumbs: Way to go TprGTO! I'll bet the numbers have some other folks going SHEESH! Nearly a second quicker than an M6? It's supposed to be the other way around. There ARE quicker, but not tonight! :D

You would have run a 13.69 if the track was only .2 seconds off tonight (reduced for Dilbert's Lying Weasel Factor). See where this is going? :thumbs:

[PadreGTO]

If you'd been as quick on the R/T, that'd correct to a 13.71, or .4 quicker.
Reaction times don't add into the E/Ts. Your R/T can be 10 seconds and your E/T and traps would be the same. R/Ts only matter when your only interest is getting across the line before the other guy (which means 90% of the time :) ).

But still, 30hp+ is excellent for the Predator alone. :bubbrub

Any chance you could post all the numbers from the timeslip Trooper? That'll give us a better idea.

Padre

[OrangeCrushM6]

You would have run a 13.7 if your R/T the second time was as good as the first. Now, lets assume the track was only .2 seconds off tonight (reduced for Dilbert's Lying Weasel Factor). That run could have been a 13.5 or better. See where this is going? :thumbs:

Reaction time only determines if your quicker out of the box. The timer
does not start until you break the beam. :)
You were right at about where I thought you would be, although I am
pleasantly surprised with the predator run. I'm glad I got mine.
Nice job TPR! You did a nice job!

Excellent results. Predator improvement was impressive. Old Goat rightfully points out that you are on the way to some really quick runs, and you dominated tonight under real race conditions.

Indeed, and now I want to see the whole slip, especially the 60-foot times. His times are an excellent advertisement for the Predator. :thumbs:

Yes, that is what frustrated me. I thought I would have run better the second time. I should look at the two runs and be happy with the Predator difference.

1.89??? Friggin awesome. :eek:

How did you manage that? What was the launch like? Just "mash it" or did you try any brake-stall? Any difference in how you launched on the two?

To give you some perspective, the best I ever managed on my 330hp WRX was a 1.801, and that was with AWD, sticky tires, and a brake-stall launch at 4100rpm. So a 1.89 is, shall we say, very very nice. :)

Padre

[TprGTO-[Robo Fuzz]]

My friend asked me how I launched off the line after the first run. I told him my left foot was on the brake and the right foot on the gas. After the 3rd yellow light, I punched the gas, and let off the brake. He told me to have my feet in the same position, except to press hard on the brake, and apply the gas unitl I feel the car start to move forward. I had the RPM's to about 1800. Then after the 3rd Yellow light, I matted the gas.

Until. Hooked on phonics did not work for me.

[TprGTO-[Robo Fuzz]]

All aside from my earlier bickering, I have two questions. How does a higher altitude affect performance? How much theoretical difference could slicks have made on my second run?

Perfect. Very impressive.

I've been learning launch techniques for the LS1 and RWD and the best I managed stock was a 2.08.

How can they get this performance out of a stock GTO?

http://ls1gto.com/forums/showthread.php?t=3702

Aren't our GTO's supposed to run between 13.6 and 13.8 in the 1/4?

[OrangeCrushM6]

The driver that got that time for SLP is very experienced.

[TprGTO-[Robo Fuzz]]

These are very experienced drivers getting those times.
Ok, thanks.

Do a search on "NHRA" and "altitude correction". My quick search reveals your 1300ft run would be corrected by x0.9862 E/T and x1.0143 MPH. IOW, 1300ft is pretty close to the average. (Try running at 4100ft as I used to do in El Paso, where times are a full second slower.) Heat and humidity also figure into the equation (search on horsepower, correction, and temperature to find some calculators).

Slicks won't help you too much stock - maybe a tenth and 1 MPH. Did you spin much? A little spin is not terrible (and it'll save your tranny/drivetrain as you add more HP). You need slicks only when you get to the point where you melt the tires on the launch.

Padre

[TprGTO-[Robo Fuzz]]

Spinning was definately not a problem. A quick chirp off the line. The impressive thing is that when the car shifted at 80 mph, the tires chirped, and the gears slammed in place hard.

"That's the way to do it!" Let me know if you get 4th rubber next time... :D

[Old Goat]

Unfreakingbelievable.... :bubbrub
Hmmmm.... You should just take a long and hard peek under there at the rubber couplers at the transmission end and pinion end of the driveshaft if you get a chance. I don't expect there to be a problem, but seeing them now and pristine will help you to see a problem later if it ever crops up. ;)

I know when I hit the gas hard going onto the highway I can feel the traction control kicking in with every change of gears on my auto.

1000= 11.81 11.01
1/4= 14.10 13.89
mph= 98.93 102.7


See now this is odd.... usually every tenth you gain on the 60 foot equates to usually 1.5 seconds overall in the quartermile. That last run should have been around a 13.5 with a 1.8 60 foot... that is almost unheard of with stock tires. The track must have been prepped well.

Any ways the other thing that really gets to me is it seems you car is not pulling on the top end... a normal accerleration is about a 20 MPH gain from the 1/8th mile MPH to the 1/4 mile MPH. You are only gaining 19 MPH on both runs. I am wondering if you are letting off the gas too early or braking too early. All my runs where I didn't either miss a shift or just plain old F*ck up, I gained 21 MPH or more. That is one good indicator of how much better your car is performing is by seeing how much is gained from the 1/8th to the 1/4.

Just for a comparison my Grand Prix when I raced it in 2002 ran the following...

60'-1.994
330-5.552
1/8-8.528
MPH-82.89
1000-11.117
1/4-13.311
MPH-104.11

Now I know other factors can come into play, but from what I have seen from racing the last 4 years is unless there is some issue a 1000 mark near 11.0 is about a 13.5 or lower 1/4 mile.

Where you logging your run at all? Did you see what timing you were running? Or if there was any engine knock? Just curious to see why you didn't pull a mid 13 or lower with a 60 foot like that... and also why is the car dying on the top end?

Sorry for the long analysis...get carried away some times with track numbers... good runs, and the 60 foot is crazy!! What track did you go to? I need one that preps like that!!

[FLORIT]

Sixty foot times... Sixty foot times... Sixty foot times...

That needs to be our mantra. A 1.89 60' is excellent! I haven't seen many under 2.0. Mine are 2.3 or worse, which is why my ET's are high. (I drive an M6.) Really good times, but I wouldn't credit the Predator tune with 30+ HP based on TWO RUNS, especially with such a big difference in the 60' times. Better launch = Better ET, but may or may NOT be thanks to the tune.

Anyway, good stuff!

I was not logging my run, and as far as timing, I am not sure what the Predator adjusted that to. No engine knock, and in thinking about the runs, the car seemed to have the best acceleration from 30-90 mph. I probably should have shifted into forth. I went to Lebanon Valley Dragway, Lebanon NY. As far as prepping, people told me that Wednesday(Test and Tune night) stinks, Sunday(Race night) night is when the best times happen.

[Huntress]

Not clear to me... which night did you run?

[TprGTO-[Robo Fuzz]]

Not clear to me... which night did you run?
Wednesday night, last night.

[Rob]

If I did the math right, the altitude correction is 13.6. Not too shabby :)

But I agree that either you lifted or something is making the car lay down. You were .8 sec faster on the second run at 1000' but another 320' and you lost .6 sec. Doesn't make sense unless you got out of it early or the tune is way off.

Yeah, you're right. He gained 8/10ths on the 1/8th but only 2/10ths on the 1/4. Something's screwy. I compared it to some of my numbers as well, and it just ain't possible. An 8.3 1/8th translates to a flat 13.0 in the 1/4.

My guess is a quirk in the timing lights - the 1/4 mile numbers seem accurate, but likely the 60' through 1000' markers were somehow thrown off. I've seen it happen before - just a glitch I suppose.

Like I was saying, many people were complaining about the times. Look at what the STI's ran, as well as the black M6. Those cars should have definately been faster.

Aye. :) Which brings the next question: on your two runs, Trooper, who did you run against? I ask because I always go to the track with the idea that I just want to see how fast I can run, but inevitably, there's a Cobra or WRX in the next lane and then my thoughts always turn towards winning. :)

Anyway, I think Trooper's final 1/4 mile numbers can be trusted, but the rest of the timeslip is screwy. Looks like he's got only one option: get thee back to the track and race some more! :slap:

Yes, life is tough. :rolleyes: ;)

1st race was against an older Pontiac Bonneville that ran 11.95. Wow he was quick.
2nd race, no competition. Jeep Grand Cherokee,17.10.
I am interested in a CAI kit, then to hit the track again. I like the MDMC setup that PadreGTO has.

[383ss]

can't say it enough. 60' times and Density Altitude make a HUGE difference in ET.

[Doc GTO]

I would have to look at the altitude being a big factor. I'm going to try and get in some runs at my local 1/8 mile track next week. I live in Savannah, GA and we are at sea level and sometimes below!!!
