I don't know how accurate the Data Master program is on the Dyno portion put here is what mine is putting out in 3rd gear. I had to shut it down @ 90MPH do to traffic. This was about 4800RPM in 3rd gear. Anyways I was getting spark retard and you could see it in the chart. Don was riding with me and I forgot to factor his weight in. I put the total weight of the car at 3700. It probably should have been more but here is what it said for that run.

348.5 HP @ 4323 rpm. 425.1 torque @ 4266 rpm.

Without the spark retard and a full run to say 5500 RPM things look promising. With the spark being pulled back that is why the high HP reading was at 4323 rpm instead of at a higher rpm. Allen

 

damn Allen.. thats some awesome HP and Tq.

are you using stock heads?

 

Hi Dave

I'm using Trickflow heads. I believe the numbers are calculated at the flywheel. Looks like 300+ RWHP is very doable. At least with the Data Master the info is on my car and not theory. Allen
