Here is the scoop. My 00 A-4 Firebird has run a best of 13.24@106 (2.08-60ft) in low 70 degree temps on street tires with a 3.42 gear (Will tune for proper gear when software arrives and I learn to use it as the car came with a 2.73 gear.), airlid, filter removed at track, Pacesetter LT and Y-pipe, airlid, airbox mod, throttle body coolent bypass and the front sway bar removed.

These are the latest round of mods. - True duals installed, and 26-in ET Streets mounted on a set of 16-in stock rims. Hoping for cooler weather.

So with a 13.24 and a 2.08 60-ft I am hoping for a 12.8x or better. Does this sound outta line? Can anyone chime in hear and tell me what they ran with a similar setup still using the stock convertor please? Any info would be helpful and if anyone can list their 60-ft, 1/8th and 1/4 mile times I would appreciate it. I would like to get a general idea of what to expect. Altitude is really not an issue since I am in Alabama. Thanks in advance. Cheers !!!

12.80's sound right if you get it retuned for the gear. sounds like your shift points are off. without a converter i think slicks are way overkill. you might bog and they might hurt you

 

My car has been retuned for the 2.73 to 3.42 swap and my best is a 13.40 on lid/catback car. I'm not the best driver, but the bottom line is, if you want into the twelves, it's tough on an A4 car without a converter.
