whats up guys just picked up my new DD today its a 2002 silver z28. Car has 72k miles, its an auto t top. looks to be stock other than exhaust. What does this car do in the quarter? also what kinda number does this car put up with just exhaust? what should my next mod be, best bang for my buck i mean thanks

13.5-13.8 give or take a little

bill2129

the other guy is right about the quarter mile times. the only other mods i have on my car is a lid and a k&n air filter. and then a programmer

I thought it should go better than that,I talked to a racer who was going 12.50s at like 112 with just an air cleaner lid

GRIDERMAN87

you talked to a guy who lies

Papagoose

You never know, he could have one of those rare "freak" camaros that push out a lil more than most.

AL SS590 M6

Even a freak won't run that fast with just a lid. What he kept under his hat was probably a high stall torque converter.

GRIDERMAN87

ya freaks might run 13.3-13.5 maybe (i doubt it on an auto car)you would have to be pushin a whole lot more to cut a second off of stock times

Inform him his lid only ls1 can nearly beat a built LT1.

I'd like to see a lid only ls1 run a 12.5

Next mod should be a lid, with good filter, and long tubes. Maybe gears depending on what you have.

You can remove any doubt. My car back in the day with a lid and a loudmouth ran a best of 12.98 @ 108. Added a Yank ST3800 and tuned the shift points with a Hyperjunk and went 12.15 @ 110. 00 Formula auto trans.

GRIDERMAN87

wat rear gear were you running?, did that loudmouth include headers, had you had the car tuned? Ive seen alot of ls1 cars run real good, but not that good, here is an example 00z28 my friend had, M6 car w 4.10s and a tune ran 12.50s on ET streets all day.

AL SS590 M6

3.23s with ET streets
Nope stock manifolds
Hyper crap for the shift points and fans only

I think Cody's car should run 13.50 as it sits with exhaust. With some basic weight reduction and a cd air kit, 13.20's should be close.

I've seen Al's car run those numbers. Cold weather probably helped him also. Not sure if he removed any weight.

I remember another local going 12.59 @ 110 with a base model Z28. 2.73 geared auto with a RAM air kit and a REMOVED exhaust from the cat back.

Mod suggestion, as always:

Sticky tires
3600 stall converter/trans-go shift kit/trans cooler
100 shot of nitrous

This would be good for 11's if you can push the gas pedal.

Yeah my brothers 02 z ran a 12.4 @112 with a 4.10 but its a six speed, stock almost. not even an aftermarket lid
