Went to the track last night and ran a best of 14.1 at 99.xx. My old best was 13.9 @ 100.14, since then I have switched out the 2.73's for 3.73's. Other mods are in the sig. I had great traction off the line, but spun second hard every time. I've come up with 3 reasons why my times sucked, which of these (or all of them) do you guys think is most likely?

1. It was in the 70's & humid, compared to the 47 degrees it was when I ran 13.9
2. Car doesn't make the power in the upper RPM's that I spend most of the time in with the 3.73's
3. The motor has 152,000 miles on it and its just plain tired.

Any input is appreciated, Keith.

 

Im guessing heat and traction issues.....what was your 60 foot? Most people will gain 2-3 tenths with the addition of 3.73's of course you need sticky tires to get those gains.

 

i say tires and you need a stall converter
