Desktop Dyno

[Rev]

What I like about Engine Analyzer is that it lets you specify exact exhaust flow #'s. The program also has a library of specific aftermarket parts that give numbers for those parts. Like flow #'s at different valve lifts for specific after market heads. Same for specific mufflers, intakes, etc. Also gives ball park figures for general generic type systems. The problem for me is tha the evaluations for after market parts aren't always very correct. I often look at these #'s with a jaundiced eye and change them as I see fit.

Desk Top Dyno/Dyno Shop only give general more generic type choices for components. Even Dyno Sim is just a refinement of those programs from Motion Software now affiliated with Competition Cams.

I really haven't had Dyno Sim long enough to fully evaluate it, but it does seem good at least. The truth is that all the dyno simulation programs can be fairly easily manipulated to give a range of results. They are fun to use, but in the end you must use objective measurements like track times/mph 1/4 mile to see what you really have under the hood.
