Dyno sheet database
 
I don't know about you guys but I thought a dyno sheet database might be of some value here. If you have sheets feel free to send them to me and I'll post them up.

14.0 @ 5100! Damn that thing is gonna burn up if you don`t add some fuel.

Guys, guys. That is not the correct AFR. That is what the dyno calculates it at using an equation. It is not actual. I have Widebands that log in the dyno in a different page. They actually are running 11 to 11.5:1. The EGT's stay nice and cool and the BSFC collaborate what the Widebands say.

The equation it uses for the AFR column is antiquated and incorrect.
