Virtual engine dyno

[lonesomecur]

Anybody tried virtualengine2000.com or a similar virtual dyno? Is it any good? Worth the money? Accurate compared to real dyno?

I've used DynoSim's Pro version for many years. It can be astonishingly accurate but also requires a lot of detailed input and some of that is best when based on experience building engines and having them dynoed for real.

My approach is to "calibrate" the simulation with test results for an actual dyno session whenever possible before I use the program to design up a specific engine. Their cam libraries and cam profile design tool set is awesome.
