You can download a FREE version of Desktop Dyno and do it yourself

Well unfortunately that isn't going to work. Apparently there is no way to share an app. I know I got this free online about ten years ago. try doing a Google search on Dyno2003. You might get lucky and find a downloadable free version. Yes, its an old version, but for the average Joe it will give you some decent comparisons.

The Comp cams website used to have it.

I use performance trends software. Next question is how many good numbers do you have to put in the program? Compression ratio, cylinder head flow, intake runner length and area, header diameter and length, carb size, what kind of accessories, what kind of fuel, remember garbage in garbage out. I have a real dyno and the program is accurate to 5% majority of the time. And if it is not usually we find something wrong with the engine like valve springs excess cylinder leakage, etc.

yes i did use the comp one but that has been gone for years. what is a good one to buy a see dyno 5

Wow....been years since Desktopdyno has come up!! Had it on my much older computer.....and guys, scammers love picking up email addresses off of web sites like these. Should communicate that kind of info in a PM.

Personally I don't care if the program is accurate within 5% or 20% - the objective is "comparison". As long as the accuracy is the same for each combo that's all that matters. They get you in the ballpark.

There seems to be another old version on archive.org. I haven’t tried it so take all precautions

I am willing to spend my time to help, if you have good numbers to input.

I just gave it a try and it runs on Windows10, if someone wants me to plug in numbers to compare the results to something more modern as an experiment we can give it a go.

I have had fun with the DD program but every time I updated my laptop the program wouldn't work with the new software.
