im doing as&m headers and y-pipe (1 3/4)...how much of a diffrence am i looking at
....i got stock t/b ported and polished last week and my car already has BORLA on it....how much rwhp am i looking at (with mods in sig)

also what kind of time do yall think im looking at the 1/4 mile (what is the car capable of )

 

You got basically just suspension mods. I would venture to say.......290rwhp and about 13.7's in the quarter.

 

13.7s you sure

thats sounds pretty slow for a lt1 with full exhuast, suspension, tires with ported t/b in a formula (light wieght)....i dunno but that doesnt sound good at all

i raced my friends ls1 from 20 roll and i beat him the whole way there..i only had the mods on my sig.

 

might i add im going to put in some 3.73s in like 2 weeks

 

Get rid of the Hypertech power programer and get some real tuning (madz28.com)and you will see some gains worth while.... Ion will help you out

 

i would say low to mid 13's at around 102mph

 

Its gonna be a huge differance

 

Size does matter. Your sig is too long. Forum rules are 5 line limit. Have pity on the dial-up people.

 

Who makes a carbon fiber hood for our cars? Do you mean fiberglass maybe???

 

Mid to high 13s - Cut the sig while you're at it

 

HOW BOUT WITH A 3.73 AND A DYNO TUNE

 

Go to the track. It'll tell you exactly how fast you can run in the 1/4.. unless you go to an 1/8 mile track I guess... btw the big brakes, stb, lowering springs, sfc's, etc.. will probably hurt the car in the 1/4 mile more than help it.

 

can some please explain to me how a full exhuast ,3.73s, and suspension mods in a lt1 run mid 13s (formula, light weight)

how much faster with stock heads ported and cran cam put in

 

Have you weighed your (formula, light weight) receintly? It's probably not as light weight as you think it is.

As far as heads and cam... depends on the combo and the tune. Also, being able to drive helps alot.
