Desk Top Dyno

I had it too but last time I tried to use it a few years ago it wouldn't work. I think it was too old for Windows 10 to deal with, it wouldn't even open the program. Not sure if it's even available anymore. Comp Cams used to have a very basic version of it on their website but that's long gone too. Hopefully someone comes through for you.

It was a fun program to use though, I used it all the time trying different things. If you put in detailed head flow numbers and cam specs it seemed to be relatively accurate. It's all in the details.
