Im curious, since I will never time it myself.. what is the average 1/4 mile time of a stock 99 SS with SLP dual duals? anybody have that car?

 

I would have to say mid to low 13's are the norm for most all LS1 cars. My 00 Trans Am ran a 13.6 @ 101 stock. then I installed a Direct-Flo lid and AFS bellows and ran a 13.5 @ 102-103, now with a cut-out I ran 13.3-13.4 @ 104 all on the same 60' times.

 

Hard to answer accurately. A 13.0 is possible but then again so is a 14.0.

But if we are talking decent elevation (say 500 feet above sea level), 60-70 degree air temperatures, 2.0 60 foot time and no driver error then my guesses would be:

13.5 automatic A4

13.2 manual M6

 

on avg, with decent conditions, low 13's to high 13's.


The 2001's(not quite sure about that year) might be a hair faster, thanks to some more low end tq and at least the same amount of hp thanks to the truck cam and ls6 intake.

 

thanks for the posts, just was wondering.... I plan on doin some mods as soon as I get some extra cash... this thing is costing me 370 bux a month as it is, hard to find extra money to add more to it!

 

you need to run the car at the track to get a baseline run before you start modding the car. then you can see if you money that you put into mods is actually worth the price.
