I ran for the first time today after the most recent round of mods. My 94 M6 z28, which has 180K km's on it, has cai, mac headers, offroad pipe and magnaflow exhaust. Best time of the day was 13.75 (2.2 sixty ft - poor driving), while my best trap was 104.5. Previous best on just the cai was 14.2 @ 100 mph.

I know that the ET can be improved alot through launch technique, but does the mph sound about right for the car's mileage/mods?

Mike.

***additional info: track was at 920 ft about sea level and temps were about 50 degrees F.

 

Yea I would expect 104-106 with your mods. Now just put it all together with a good launch and you will be low 13's.
