I do however know that in this situation (for some reason, most likely related to torque converters) this derivation isn't linear on chassis dyno's. I have had disscussion about this with DynoJet and several other Dyno manufacturers. Many experienced tuners will tell you the same thing. Apparently the log for HP calculation is based on time and velocity. More accurately time of the dyno pull and terminal velocity of the rollers(figuring in an aceptable variable for average weight of the vehicle). One might argue that you should be able to determine torque in a similar fashion. Remember however that torque will tell you how agressively the rollers were turned. With a stick car there is a direct link albeit clutch slipage. I'm just reporting the number. I also accept the fact that nothing is perfect, so we need to find an acceptable level of comfort with our data.
My A/F was 11.7 to 1
