Took the 04 to the track

[jasontio]

Took my new 04 to the track this weekend. It was very cold about 55 so traction was really bad still stock tires.

Best was
60ft 2.17
1/8 9.16 at 79.6 mph

Most runs stayed in the 9.4 to 9.5 with around a 2.3 to 2.3 60.

Going back this week with slicks to see how it runs when I can get on it out of the hole. I thought it was pretty good for exhaust CAI, Diablo, Shifter.

Oh my predator helped me pick up around 1 mph you could really feel it on the big end. Going to the dyno soon to find how much it helps and tweak it alittle bit more. Thanks for reading lol.

Be careful running the slicks on your GT. Some guys have snapped their rear-ends running such sticky tires. Good Luck and nice runs, thats a good 60' if you say the traction was bad becuase of the temperature. Id try drag radials, but thats me.

Well, by that logic then he should avoid DR's as well. Several people on the board have snapped the axles on DR's as well. Just be prepared either way when your jumping from 2.1 60' to a 1.8 or lower.

My best through the 1/8 was 9.3346 at 76.31, and that was W/O the water pump or shifter.So I dont know what I will run now.Also I was thinking about that diablo tuner but $400 is quite a bit.1MPH in the 1/8 is pretty good I guess, so anyone know about what it would be good for in the 1/4?

nope, not true. yes anyone running sticky tires runs the risk of busting the rear end. but someone that is running drag radials is more apt to bust a rear end, than someone running slicks. reason being, is that there is very little flex in the sidewalls with dr's which puts more stress on the rear end. slicks on the other hand obsorb some of the initial stress when you are launching

a well driven bone stock gt should be running 8.9-9.1 in the 1/8

gotcha man, thanks

no way...

slicks will hit the rear end way harder than drag radials...drag radials have more tendency to spin which will keep the rear safe. But a set of slicks will hook and take an axle fairly easily.

my take:

drag radials hook and break axles and
slicks abuse a rear over time and cause the spider gears to fail

Not around here they don't I mean it would be possible but would be the perfect race.

 

[hotmustang331]

If corrected then yea most of us would be running 8.9-9.1s.Or were we to race at sea Lv on a cool day with low humidity, and any pressure numerically higher than 29.92.Yea I know quite a bit about pressure and the such, because I am a pilot. Ok as an example, lets say your at a track thats at sea lv, and the pressure is 29.4.Then their is a track thats lets say 485 ft above sea lv but its pressure is 29.92.Anyone know which track will provide better performance? I will congratulate the winner tomorrow LOL, I need to go to sleep.BTW please explain why you chose your answer.This might help people to know what days are the best days to run your car.(I forgot to check when I ran my car )

mod depot has correction calcs, they are great for a racer to monitor mod improvements

agreed


i've seen more broken parts due to dr's, than i have slicks. most people running slicks upgrade the rear end though, so that could have something to do with it as well although there is a guy around here that was running slicks at the track last week. apparently his rear end puked the next day on street tires. that was the worst rear end damage i can remember ever seeing. it was BAAAAAD

I am just taking a crack at this. I would have to say the lower track would perform better, for one, it would have more oxygen rich air and the slight difference in pressure (29.4 to 29.92) wouldn't matter. Pressure means the same thing where ever you go. Again, I am just guessing, I have some scientific ideas that I am going off of, but just guessing.

i snapped mine on drag radials on the 15th run BE careful

Good guess, but the answer is neither.That small difference in pressure actually accounts for nearly 500FT..amazing huh.There is the same amount of air at basically any altitude, just less pressure the higher you go, if you raise altitude but also raise pressure it will be the same.Most think that the oxygen to nitrogen ration decreases with altitude, in other words that there is less oxygen but more nitrogen...and thats why we cant breath good and the cars performance suffers....well infact the ratio is the same but as the pressure decreases the air becomes less dense.And as it gets lower, the pressure and amount of air being sucked in becomes inadequate to force the oxygen over our membranes in our lungs, stopping the transfer of oxygen to our blood.No with engines that low pressure means less air volume in the cylinders, hurting performance.Goes to show you that checking the barometer for the best day to go to the track WILL help quite a bit.I believe thats why some guys hit 13s in stock GTs....Cool day with a high pressure at a sea lv track.

i fully agree hotmustang
