I haven't played with it in a long time but it always seemed pretty optimistic. I wouldn't depend on it for accuracy but it might at least allow you to compare one combo to another. Real world numbers would almost certainly be lower by a good bit.

You somewhat get what you pay for.
In the world of engine modeling Dyno 2000 is relatively cheap. Even higher-end sims such as Engine Analyzer Pro (my choice) and Dynomation Professional - which require a good deal more data input than "consumer grade" software - have plenty of margin for error, especially due to the increased opportunity for the old garbage in, garbage out thing. (IMOE estimating post-collector exhaust system flow is one such conundrum that can significantly skew one's results.)
In the end, all such programs have one thing in common; they're all based on "black box" maths. The difference comes down to how complex is the set of formulae by which the program in question arrives at its results. Still, Dyno 2000 is a lot better than the last version of CamQuest with which I played (a.k.a. How to Select a 268 Cam), and IMHO is more than sufficient for evaluating many a proposed engine build mod. Just don't count on its results accurately reflecting a real-world dyno session. My $.02

Good morning all
I compared Comps xe 268 cam on Dyno 2000 and comps simulator and got two different results. Comps program was a lot lower. I wanted to compare the 268 with an Isky 264 mega cam. On dyno 2000 the results were about equal, but on comps, naturally you can't imput other brands. So I was wondering , are these cams equal in results ?
