my #s from buschurs md 369/359 my best run 11.538@122.01, car with me and some stuff in trunk 3320lbs using dragtimes calculator to get flywheel hp and then minus 74 to get whp its right on!!!

 

Good time there. What are you mods?

 

Glad it worked out for you. One quick observation to add: As the power increases above say 450 or so, the drivetrain loss will increase, but only slightly by a few horsepower. 74 seems to be my magic number for a good average. Again, the key is to get your exact weight at the time of the run, including driver, laptop, helmet, gear, etc. Just roll across the scales after the pass and add 2 lbs for fuel used.

Another good example would be Indy's pure stocker. He ran 12.86 at 104.84 I believe. His car weighs in at 3490 with him and gear. That shows a 'drag calculator' crank horsepower of 319.11 ( 319 - 74 is 245) with only a tune. That's about right for what we've seen on stockers that are tuned. Pretty close again.

weight corrected per Indy's specs. I was calculating BEFORE he made his 'pit stop' at the gentlemens room. And here I've always thought you were COMPLETELY F.O.S. Now we know, just 30lbs worth.

 

9sec9 with the fuel load I was running I'd say closer to 3490, that would be about 319. I'll try to get it on the scales later this week.
