Owen Posted June 26, 2002 Share Posted June 26, 2002 Is Desktop Dyno2000 worth getting? It's not too expensive and there's also a CD with a bunch of camshaft data in it. I'm still poor and couldn't find any bootleg versions on the net...Jegs sells it too I think. Owen Quote Link to comment Share on other sites More sharing options...
Guest Tom Scala Posted June 26, 2002 Share Posted June 26, 2002 I was never a big fan of it. The inputs are too general and it seems to give over estimated HP numbers and lower torque vales than the real world numbers. It is relatively inexpensive though and still fun to play with. I like the Performance Trends Engine Analyzer series of programs. They are more expensive but the inputs are very detailed and output is much more accurate in my experience.

Guest greimann Posted June 26, 2002 Share Posted June 26, 2002 I like it because you can test different components, especially cams and see what the comparative effect would be. Saves a lot of guess work and perhaps buying the wrong thing. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted June 26, 2002 Share Posted June 26, 2002 I think its value lies in that you can put your set-up in there and then compare it to what you can do in the real world. Then you can make changes and see what the computer thinks will happen rather than waste money. I have a friend who uses it religiously, and his car never came close to what the program said it would, and in the end, I think it all boils down to bench racing. For me, show me a dyno pull or a time slip if you want to impress me. I don't care what a computer says your car can do, what it does is what I care about. That is my blunt .02.

Kevin Shasteen Posted June 27, 2002 Share Posted June 27, 2002 I have not used the Performance Trends Engine Analyzer but have heard good things about it; definately a little more expensive. About DD2000 or Drag2000; they are cheap and I dont look at their outputs as "the Gospel". What I look for are trends. In other words; what are the outputs when I have these compenents as opposed to changing the data by one point/or one unit of data. Such as changing the camshaft's duration by one point at a time & noticing the effects of when/how & where the hp/torque is altered. Everything you (we rodders) do to modify our car will be based on our experience as we approach our projects. The more experienced you are, the higher level of difficulty our modifications will be also. So everything is relative. Use it as a learning tool; and when you have surpassed what it has to offer-then purchase the more expensive software.

Drax240z Posted June 27, 2002 Share Posted June 27, 2002 Anyone know if any of these programs will handle odd modifications and odd engines? It would be idea if we could simulate what a 600cc motorcycle engine does at 11,000rpm while breathing through a 20mm restrictor... Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted June 27, 2002 Share Posted June 27, 2002 Desktop Dyno is pretty much an automotive program. Its main feature is preselected configurations for a particular engine (Chevy, Ford, Buick, and imports too). You can put in your own parameters for bore, stroke, cylinder head flow and such, but I think it would be a stretch attempting to simulate what you want with a bike motor.

Drax240z Posted June 27, 2002 Share Posted June 27, 2002 Oh well I guess we'll stick to the old fashioned way... you know, computational fluid dynamics. Just a shot in the dark... Quote Link to comment Share on other sites More sharing options...
