Ok now heres the thing my times are killing me
last year without the alum heads and intake change and fiberglass bumper it ran the best of
60'ft = 2.003 , 1/8 = 8.29 , 1/4 12.82 @ 107.74 and rand consistant around there a few times...
This weekend after the new parts and work done to the car alum heads, fiberglass bumper, new intake and my beutiful paint job haha it ran slower... even though we had absolutly no time to tune the car in or even set the timeing we ran it as is and got the following after 4 passes.
1/4 = 13.11/13.17/13.32 @108.93/@109.28/@105.95
60'ft times were 2.001/2.026/2.028
so my mph went up a little bit but seems like my 60'ft times are just killing me, but can someone let me know what this is telling me about the car....
The car just isnt launching hard its still very doggish off the line and just dosnt jump it kinda picks up and goes haha and i still think i need more like a 4:11 gear since i seem to have some left at the top of the track.
