i have a 99 trans am this is my set up. i have a ls1 motorsport lid tci 3500 stall 373 gears hooker long tubes off road x=pipe ls1 hot cam ported tb and tb bypass also a trans go shift kit. my recent time slip was a 1.736 60ft 1/8 80.68 1000 10.588 1/4 12.76 at 105.53 does this seem right , because at 1000 the car seems like it is not pulling any more. what do you think i know mph is down

The mph and the time was slow did you spin off the line?

no, your gear tire combo look good, but i still think your off a lil on the 60 ft with that setup.

SAM99LS1, try a tire with a smaller footprint, like a 26x8.5 ET Street. That 11.5 tire is murdering you on the top side. I would dyno the car also, check the air/fuel, and make sure you are making decent power! Stew

hey stew, you dont since he has more gear and a stall than you it shouldnt hurt nearly as much as yours did with the streets.

I would think something is not right,i ran 12.72@107(1.72 60ft) with same bolt ons and stock cam and TB ,last year with Vig 3600.
Dropped to 12.432@ 108 (1.67) with Yank SS4000 and E/T streets.
IMHO you should have your car checked out,Maybe on the dyno with wide band O2's.
MPH is real low for your mods.
My pig weighs 3636 with me in it.
