Not really, before I had my tune, I was pushing about 292 rwhp on a good day (when my f'in C&L meter would work properly). I ran a 13.47 @ 107.2 mph spinning all the way through 1st and second (I pulled a 2.6 60" time). This was on a very stiff suspension, non locking rear and street tires with 5 speed manual with stock shifter and 3.08 gears. So I definetly lost some time and MPH on that run. If I had optimal track conditions and equiptment to leave the line better, I am almost certain that I could've pulled a similar time/mph as rob302. My car is a 1988 XR7 with every option and a (at that time) 240lb driver.

There are also SC'd 4.6L MN-12 guys pushing about 310-320 rwhp and running high 12's @ 109ish mph, and their cars weigh just a hair under 4K with driver.

About 292 RWHP - is that a dyno number? My car ran slower as predicted by those in the know when I got better traction. It ran 108 with 2.0 60' and 107.2 with a 1.7x 60'. Some of the other things you mentioned may add MPH though. I think my car must run on like 7 cylinders of something! BTW a 20th Cougar (all options) weighs 3700 lb with 170lb me and 1/2 tank of gas.

When I got the dyno tune, they did 2 pulls on my current configuration before they began tuning, it was 289 rwhp. I added 3 for 1/4 because my dyno session was indoors, in the summer, in hot-ass Atl Ga. I ran the 1/4 time in the fall where I live in NJ on a 56 degree night. It may have been more or less at the track because I came to find out from the J-man, that the stock sensor that was in my C&L intermittantly did not return voltage to the EEC! So there were some instances where I pretty much wasn't using a MAF meter at all.
