Now, here is a quote I have from Eric G. So if anyone knows there Math Science skills help us get this figured out.
""I dynoed on a MAHA dyno at superchips facility. The dyno had two rollers instead of one. I believe this is because this dyno shows actual loss of power that your tranny and other components can rob. Not sure though but i think this dyno is one of the most expensive ones out there. Its made in Germany i believe...like BMWs. he he
It also measures in NM (newton meters?) and there is a formula for computing it but i cant remember it. After the custom tune i got 176.5hp and 232nm torque. Again i cant remember what that comes out to.""
To convert newton meters to foot lbs. you need to multiply by 0.7375622. That would be 232nm multiplied by 0.7375622 that equels 171.11443 ft. lbs. You see that doesnt look right. You cannot compair readings from different machines, it is invalid data. You cannot even compair readings from 2 machines that are the same brand and model. I'm getting the feeling that most people do not understand this! Anybody that tells you they can measure the drivetrain loss's because of the # of rollers the machine has is not being truthfull! Drivetrain loss's are educated guess's at best. A chassis dyno will tell you if your clutch is sliping, but as far as it being able to tell you any other loss's such as frictional loss's etc. it can not do it.
