Computer engine simulations

I was wondering what you guys think about computer programs like desktop dyno. I have been thinking about getting one of these programs but am not sure which to get. The two big ones seem to be desktop dyno and engine analyzer. Which would you guys recomend?

Because the nature of this question has more to do with ENGINE Horsepower.....I am moving this question to the Engine Forums section......where you should receive most and hopefully better informed answers.....

We use EA Pro all the time. I have used Desktop dyno as well. EA Pro is a much better and more accurate program simply because it's much more sophiticated. That also makes it much more complicated to use correctly. You'll have to spend some time learning how to input all the data. It's also more expensive. The greatest value to EA is the amount of feedback data you get on an analysis. That feedback data provides a ton of direction on how to make the engine perform better.

If this is just a hobby and your not designing engines then DD 2000 is a better choice. It will get you close with off the shelf stuff you commonly find in catalogs.

Rick is right. EA Pro is very expensive when compared to DD. And very complex. It even permits the entry of specific geometry information related to the shape of the ports, I'm told.

Personally, I have both DD2000 and EA (not pro) plus. The plus is a set of accessory functions for EA (again, not pro). EA alone, I think is superior to DD. In fact, when I got my most recent computer, I don't think I even loaded DD on it. I may have, but I'm not using it at all. EA (again, not pro) permits inputs of a wide variety, including a lot of specific header information related to both primary and collector length and size. You are given a large database of parametric information, easily loaded by product name (i.e. Performer RPM intake) to set up the limits and characteristic variables that the program uses for the various engine components. You can add additional information if you like. For instance, if a "new" cylinder head becomes available, you can input its chamber size, general chamber shape, and actual flow bench numbers (up to 10, I think, per valve) creating a part file for the "new" head. You can also add a "new" hydraulic cam. BTW -- I think EA (again, not pro) has the full Comp catalog of cams for small block Chevys already built right into the program. And, you can download it free from their website to try it, then call Kevin with your credit card info, and he'll give you passcodes to make your sample copy into a full-up working copy. No delays. You can probably tell I like it. But, rest assured, I do not have any affiliation with them except as a customer. It's a cool product. DD is OK, but I really like EA.

109 or so, purchased direct.

Yeah right! Im not going to put 400 dollars into a simulator. But thanks for the idea.

I did download a demo of EA and messed around with it for a while. Seems like a good program and may end up buying it.

desktop dyno, never built an engine with info I used, too bad I can't build diesels on it! (diesels... )

it's fun to play around with, and have competitions with friends about engine building within certain parameters to see who can build the most powerful, or most torquey engine.
