My car runs 7.79 @ 86.9 mph. The weight of my car without driver is 3540. I did not drive the car when it went 7.7 the guy who did weighed around 165. My question is what kind of RWHP would my car have to have to run those kind of times. I have run 7.8's and I weigh 280.
Thanks, Larry

 

That's about the same trap speed at I ran with a raceweight of about 3550. According to what you've said your raceweight was about 3705 (how'de you get it that high anyway? Big stereo or something?)

I'd guess my RWHP should have been about 320 based on my mods at the time. You're heavier so I'll guess 335-340 for you.

But then again, this is only guesswork!

 

yep, 1/8 mile mph is hard to judge rwhp by since wind, aerodynamics and gearing can make or break the finish line mph. Steve's guess is probably pretty close.
