How accurate is borg warners matchbot. I got these results when i put the variables right.





Has anybody make this matchbot calculator and then go to actual dyno and compare results?
 
Its so high because of boost.
At 2000rpm it should maybe be 80-85% but otherwise it's quite accurate, those values matchbot gave to me when i put boost to it.

If the VE were based on boost, it would be well over 200%
The numbers that are automatically inserted are for modern 4v engines that may have variable cam timing. The blue "?", will tell you the assumptions.

You want to use the VE% of the engine in a NA application for the matchbot.

A 8v redblock with a stock intake probably isn't even going to be 95% VE at peak torque.
