Dyno results
|
|
The following information is from a NHRA super comp engine. The engine was dyno'd prior to thermal cycle process, completely taken apart, thermal cycled and reassembled. After it was finished, the engine was again dyno'd to confirm the results. See the results below.
RPM- Revolution per minute
CBTrq- Corrected torque in foot pounds
cbpWR- Corrected hoursepower
FHp- Friction hoursepower
VE- Volumetic efficiency
ME- Mechanical efficiency
FA+FB- Fuel average in lbs per hour
A1- Volume of air consumed by the engine
BSFC- Brake specific fuel consumption
BSAC- Brake specific air consumption
