[dyno] Can someone explain this?
OK, so I had my 93 6-spd dynoed a few weeks back on a SuperFlow, and for the life of me I can't decipher all the results data.
In horsepower alone they have listed: STPPwr(CHp), InrPwr(Hp), and WhlPwr(Hp). So what's what?
The graphs say "STP corrected Power vs. speed" so I assume that STPPwr is the Corrected wheel power (corrected for pressure and temperature), therefore WhlPwr would be the actual recorded HP before the correction. Lo and behold, if you multiply WhlPwr by the correction factor, you do indeed get the STPPwr.
The real question is the InrPwr, which is a lower number than the other two, not only is it lower but it is about 85-87% of the WhlPwr number, which leads me to think that this is the actual, non-corrected wheel power and the WhlPwr is actually a software computed crank HP number. Now that's confusing.
Can anyone tell me what's going on??
You can find all the data, including the graphs at:
