Anyone use this program?

My horespower numbers seem OK, but my torque numbers seem to be off.

Any input?

Well, in comparing builds that are posted and run on the desktop dyno program. Plus, from feedback from different guys on the board.

Torque and horsepower are mathematically connected by a constant. You can't have one of them right and the other one wrong unless you calculate wrong.

I have two differant programs. Motion Desktop 2000 and DynoSim Desktop dyno. The Motion appears generic, does not get into details of head flow @ cam lift etc thus producing differant numbers from DynoSim. I just got the latter and tend to believe the program with more detailed input. So I tend to agree that numbers will be off some between programs.

On my program I can control the following cam profile:

duration at .050
lift at cam and valve
lsa
centerline
rocker ratio

Heads I can use port dimensions and flow numbers if I have them.

Same here with DynoSim. This program is made by Comp .
