I know there are a lot of factors here such as 60' time, Altitude, Air Density, Etc.
As my regal sits now its 3652 lbs with me in it.
Mods:
XP Cam, 9.4:1 Compression, 3.3 Pulley, SD Headers, 3" Cat-back, Intake, DHP Tuned (KR Free) 4340 IS, 7/8ths chain (3.29 Gears)
There are some more mods but they are more support than anything else.
How fast should this be in the 1/4? My thoughts were Mid 13's.
