What does STPTrq Clb-ft and STPPwr CHp mean?

[sasilverbullet]

Please help me understand my dyno results. Was done using SuperFlow WinDyn Software.

What do these mean:
1. STPTrq Clb-ft
2. STPPwr CHp
3. VolEff%

Thanks!

1) Is your Torque rating, expressed in LB-FT

2) Is your gross horsepower rating

3) is your Volumetric Efficiency.

STP = Standard Temperature and Pressure
C = Crankshaft

So, your STPTrq Clb-ft and STPPwr CHp are corrected crankshaft horsepower and torque.

Barometric pressure and ambient temperature will affect power output. Using a "corrected" figure attempts to normalize those effects. Typically, these numbed are corrected to 29.92 in hg and 60 F.

VolEff% = Volumetric efficiency in percentage.
