What's Wrong With My Track Times, Something Doesn't Make Sense!
See sig. for vehicle details.
I took the car to the tarck last Wednesday, 50+ degrees. I ended up running the following times
Pretty much a 12.39-12.45 1/4 time. The real kicker is the 1/8 MPH and the 1/4 MPH. My 1/8 MPH was 88-89Mph. My 1/4 MPH was 110 all day long even when I ran 12.6-12.8. Shouldn't a 12.3-12.4 be faster than a 110 trap speed. I am running a 3:23 rear gear and Eagle F1 tires (275/40/17). My 60' times were between 1.85-1.95 (not to bad for street tires).
So, what can cause the car to pick up only about 21MPH the second half of the track? I was wondering if the person who did the programing of the car didn't put the converter into lockup at any point? It is a small 2800 Stall. The question is what happens if I put a 3800 Stall and a set of Nitto Drags on the rear. Does that get me a 11.9?
Thanks for your help!

I also run 88-89 mph 1/8s and 110 1/4s. I figured that my cam is just lowend biased so I picked up alot in the slow end and not too much at the fast end. In your case, I think something different is going on. Something is sapping your upper rpm power.

I was running a 12.3 at 115 mph... N/A with 1.8xxx 60's I had a 1/8 mile time of 8.0's. Just spun when I hit second, track sucked. I should have been well into the 11's with my mph time.
I need to get tires and shocks bad!!
