1/8th is 82-83mph
1/4 is 102-103mph

~20mph pickup on the big end about normal for my combo(in sig)? or am i dying out on the top end?
car is somewhere between 3400-3500lbs

is my low trap speed due mostly to the heavy race weight? most others with similar combos trap in the 105-110 range..

my home track elevation plays a small part in it too..at another (lower) track its seen almost 105..

damn convertibles..

Take your 1/8 mph and X by 1.24 this is about what your 1/4 mph should be if your car is working.

My car traps similar to yours. You are 2-3 mph faster in the 1/8th than I am but our 1/4 traps are the same so you may be losing a little on the big end, although it could just be the difference in motor design, I don't know. My best is 1.918 60', 8.708 at 80.35, 13.548 at 102.08. My car weighs 3460 with me in it. Just thought I'd throw it up to give you something similar to compare to. My mods are listed below.
