Just wondering if any of you guys have this software. It's a relatively low cost package, called Desktop Dyno2000, is easy to use and very effective at showing the relative performance of design changes. This package doesn't seem to have quite the flexibility needed to model every unique part, but it will provide a general idea of what you can expect from your engine. This package is available for about $50 from Motion Software, Inc. I think I will put that on my Christmas wish list.

A more comprehensive wave analysis package is available from V.P. Engineering called Dynomation. But this package sells for considerably more ($600) and appears to be only available for DOS. I am wondering what the difference is.

 

yes soaring i have this sofware and its really cool...

 

Hey Glen, after running it and the older version, I have found the power figures to be somewhat optimistic. particularly under 2500 rpm. What I find it usefull for is mapping a torque curve, make changes and look at the effect it has on the torque curve. For a street car you want plenty of torque under 3000 rpm, and getting the curve as flat as possible will help the car be faster. A steep curve will need deep gears to get it moving as the bottom end wont have enough torque to move the car.

So.. disregard the numbers as being realistic, but look at the difference in the numbers relating to RPM for each combination. Its really easy to make a 500hp 302 on it but not so easy in real life.. and even if it makes 500hp at 9000 rpm, that doesnt mean its going to be a fast car.

 

I have this app and Desktop Dragstrip (i believe that's what it's called). They are both fun to fool around with but are not 100% accurate. It is also limited in the types of engine components/modifications that are available to choose from. Still fun and worth the money. I bought both of these on ebay for like 30$.

 

I have this, and it is very optimistic. It is a good tool to chart some differences, but not good for getting real accurate numbers.
