I remember seeing Charlie using Engine Analyzer Pro software way back in 2005. Yes, that Charlie.

Anyway, it's very interesting software, albeit a bit pricey and you need some basic understanding of the internal combustion engine to use it properly.

If you ever wonder which camshaft would be ok for your particular engine combination, or how 4" crank would change your particular engine combination, EAP is one way to find out. Other ways are of course ask from pro...or read Internet forums.

Here's an example of EAP's engine simulation. This is a stock LS6 engine, defined in the program. First the basic stuff:



Then here's the heads information. These are stock values, but you can freely modifed it as you wish. If you have ported heads, just change the values accordingly:



Here's the simulation result. 423.8 hp @ 6000 rpm's and 407 lbs @ 5000 rpm's:



A bit off from official LS6 rating..

By going through the simulation, it's rather easy to see why there's a difference. It's because the software optimizes WOT ignition advance and as you can see, it's far from stock. Here's the optimized advance:



...and here's the stock advance:



Now, if you manually define the advance for the stock LS6 to follow the GM settings...:



...here's your end-result. Almost identical values compared to GM-advertized values:



Nice, isnt't it?

 

Yes, looks great. Thanks for sharing. Will it calculate accurately for twin turbo applications? What is the best way to get a copy of it?

Also, why in the notes does it say: "Detonation likely, Piston speed Extremely high."?

 

I was just saying after watching Charlie use it, I wanted to have it for myself. Its really nice software!!

 

Dont forget though, any results will only be as accurate as the information you can provide it with.

So there are still lots of variables that can affect readings.

If you can fill it with accurate info, I'm sure it would be great.

 

Definitely!!

 

very cool.
