Default Re: Desktop Dyno numbers, look correct? (ld85)

The output looks like it comes from the Engine Analyzer simulation program, not DeskTop Dyno.

If the program provides output, it is "correct", however, the accuracy of these programs' output is primarily a function of how precisely you can model the actual engine configuration based on the input data you provide. Accurate head flow and valve timing data is very important to achieving results that accurately predicte actual enginer performance.

Cool, I did not realize that there where more software options for the estmation of an engines output. Make sense though now that I think about it.
