Was just wondering if there are any good internet/computer software dynos out there. Weather it is a download or a website?

I understand that there is nothing like the real thing physical dyno. Just curious if an online simulator is worth while.

Internet dyno.... Is that like a keyboard racer?

Desk Top Dyno. Not that accurate in total HP, but good for seeing what a change will do, such as replacing cam, bumping compression and so on.

I put the specs from a motor I had dynoed into Dyno Sim and the numbers came out pretty close especially the torque curve.

If you input good information into DD you get decent results. It works good with NA engines.

I get some F'd up #'s when I try blowers.
