My 360 - anyone got dyno software

I agree with Blue missle 100% on this. The Desk Top Dyno is an excellent program to see how things like cam timing and valve size can effect engine operation and output. While generaly, not a bad program.

I noticed that the change from dual plane to single plane intake manifolds produce an amazing 50 plus extra HP everytime. This simply is not the case or possible with some builds. The single plane intake must be used only in super serious race like builds and still be taken with a grain of salt.

Still, it's a great little learning tool to see how things can be effected by changes you want to do. But remember, this is only a sim. Actual results will be different. Not "May vary."
