Took something I had made a few changes and did a rough simulation.


DA = 0


60 Foot ET = 1.5076
330 Foot ET = 4.4113
1/8 Mile ET = 6.9378
1/8 Mile MPH = 96.7141
1000 Foot ET = 9.1421
1/4 Mile ET = 11.0173
1/4 Mile MPH = 120.2224

My guess is 500hp based on the very high quality of the build.

The first test is some what typical, and the second test was my best. From what I can see from the average power, that should get me there, 4200-6100 RPM (11.00) should be easy.

HP... I'm just wondering if you made any pulls starting at a lower RPM ? It would be interesting to see what the TORQUE numbers would be from say 2500-3500rpm. Very Good results from this project. MB

Thanks, I didn't pull it lower than 3500, I knew I'd never see that on the track, I doubt there was more TQ below 3500. I can tell you from driving the car off idle TQ is very good, but as you know theres always a trade off-and I'm sure it going to be on the top. But it sure runs good, just wonder what it could have made if I really got after it, intake work, oil pan work, lightened the bottom end up, 1.8 intake rocker, more compression. Vacuum was 15 inches @ 750 RPM @ 6400 feet altitude. Heres a video.

There is more torque at lower rpm. Look where the tq is at 3500 rpm. Your correct and probably never see it at the track.
