i was looking over those papers i got from that Dyno run i did. and i noticed that i made 150 HP...but in smaller print underneath "with WCF 155.0". and torques the same, "max 220 'with WCF 228'". whats WCF? and is that the number im supposed to go with? and how are those number greater then the max's? isnt the max supposed to be the max???

Has to do with what correction factor they run. Most dynos use the "higher HP" SAE #s, only a few do true HP. I'm not exactly sure on which test is which (there's 30+ ways to correct HP), but if you post up the actual graph we can do a little research.

It might be "Weather Correction Factor". Did they measure the temp and humidity?
You can dyno a motor two different days and get two different reading, depending on temp, barometric pressure, humidity, etc.
Most dynos use a std scale correction factor for this so you are actually making fair and valid measurements.
I think.......

Might be "Without correction factor", too, which would explain the higher numbers. The 150 might be corrected, the 155 might not be.
