oo trans am slp lid, gmmg, ssra, a4 13.55@103.21 mph 2.0 60 ft with nittos. there was a 98 z28 with loudmouth and lid running 13.5s also, but at 103-104 mph wonder if my mph will get better if i get rid of the ssra? dont know if this is good for my car or not? thanks

 

That looks right on the money for me? Mid 13's @ 103 - 104 is exactly where most stock LS1's run (a lid and cat-back aren't far off stock). A 2.0 60' time is also ok. Don't know whether you've got 2.73's or 3.23's, but running Nitto's with 2.73's won't make much difference, since 2.73's don't break loose all that bad anyways.

 

i thought it would be a little better since i do have 3.23 gears , i was thinking the car should be a solid 13.2 @ atleast 105, the car doesnt seem to have anything wrong with it, except my headlight motor is shot, but that wont hurt times. i read a post where a dude was saying he took the ssra off and ran .1-.2 better and 2 mph faster, but he also didnt have the front sealed off, i dont have the front sealed off either, wonder if that would help? im a tad dissapoonted.

 

That's funny. I gained about .2 in the quarter with just the addition of my SSRA

 

when you gained this .2 did you have the front of the airbox sealed off with the weatherstripping?
