I have a 2000 camaro z28 with lid, ls6 intake, lts, ory, borla catback with cut out... and I recently went to the track an ran a 8.75 at 83.43 . The temp was at around 77 degrees. I just want to know how much i would gain from a tune and some 3.73 gears. My best is a 8.51 at 85 during cold weather.

dont know why you are mad about those times they are about the norm for those mods... i think that witht the gears and tune you might just run 8.4-8.5... but thats IMO

tomtomLS1Z28

well my friend has exactly the same mods and he runs a 8.18 but has 3.23s... so thats why the is there

well i got almost your same mods and best ive gotten is an 8.77@84mph... I think the rest might just be a driver mod. I'm sure my friend could run my car better than I do and post a better time, is your buddy stick or auto?

weight

tomtomLS1Z28

my car is a A4 an so is his, and we are at the same weight so the only thing i see wrong is that i need some better gears an a tune. btw my friend's cars isnt tune either. is your car an A4 or 6 speed??

A4 with a shift tune..last time a ran it was with no headers and when i ran with headers I had a bad 02 sensor..but all that is taken care of now so will go to the track soon and see what I run now..should probably be 8.4

imlooking

could you explain the shift tune !?!?

would it be necessary with 3.73's or would you do it with stock gearing also !?!?

I basically have the same mods as you minus the LS6 intake, and ran a 7.95 @ 86MPH with an A4 Trans
It was a little cooler tho than 77*
I assume it would run a 8.2 in 77* weather..
With a tune you should see a gain.

tomtomLS1Z28

That's a good time bro... man i just want to get my car to run good so sooner or later ima get the tune and the gears.

Driver mod, tires, and a converter.

nothing much has to do with the driver when the damn car is a A4...

thats not always true..my buddy had a formula with the same options as my z28 and my car out weighed his easily by over a 100lbs

not all cars put down the same power also, just because you and the other person have the same mods its going to perform exactly the same.

Yeah this is true. Another difference is that I have Cloth seats and SS hood and wing, and a ported TB. So mine might weight a little less than his.

cloth or leather doesn't matter, thats just a skin so to speak that covers the foam. What matters is if the seats are power or not. SS hood is lighter than a z28 hood, but im not sure on the wing.

tomtomLS1Z28

But i dont think that makes 100 pounds of diff. I mean his car is 2000 camaro ss and mine a 2000 z28 so i cant see that much diff in weight.

usually after market suspension like torque arms, LCA's, panhard bars weigh less than stock.

subframes add weight and wheels make a big difference too.

tomtomLS1Z28

well he has subframe conectors an zr1 wheels, an i was on stock wheels. i guess his car respond it better to the mods.
