Exhaust, Headers, CAI, Cam, Intake. I think that should put you into the 12s. Correct me if im wrong tho, Mr Luos

Drag radials. Practice.

how about some funny gas + slicks? cheaper and easier than cam?

Mr. Luos · #5 10-18-2005, 07:25 AM

Slicks will kill the rear end.

Most of these cars have a 12 second run in them with some practice and slightly stickier tires. No mods other than the tires.
Gears/lid/catback would insure this.

wanna get it in the 12's.. all u have to do is start it lol jk well i can tell you this much. my cousin has a 02 firehawk and when he had full exhuast and some other shit he ran a fastest of 13.1. now he has a tune, throttle body, heads, and some other shit and i know he's running mid 12's easily.

Heads and cam cars should be running 11's easy.

A guy I know took his 2001 Z28 to the track w/ just a cat-back and ran 12.98

daveshapellSVT · #12 10-24-2005, 10:11 AM

yea i heard of stories like that, but i personally wouldn't believe it. fully moded LS1 powered cars barley run 12's. i know a whole bunch of guys here in rochester with f-bodies, including myself, and i've never seen a ls1 car run 12's with out a bunch of mods. did he maybe have slicks cause then i could see it

chadm_88 · #13 10-24-2005, 03:43 PM

I know someone with an LS1 in my town completely stock who ran 12 something. It's not impossible.

daveshapellSVT · #14 10-24-2005, 04:23 PM

yea, but how do u know its completely stock? u can't see cams, headwork, or a chip.. a lot of ppl just say its stock cause they want ppl to think there car is better for some reason.

Mr. Luos · #15 10-24-2005, 05:24 PM

There are a couple LS1 F-Body's that have gotten into the 12's completely stock. Just a couple though.
