Trick Flow small block heads
I just looked at that screen again....... there is an option for “weather station” or “enter weather info manually”.
Which was being used that day?
Was it correct?
Any way to look at what the weather data was for one of the pulls?(most dyno software will store the weather data used for the pull)
Sorry if this is already widely known and understood....... but in case some viewing aren’t in the know.......
The correction factor is used to estimate what the engine power would be in weather that is considered “standard”.
What that standard is, is different for different SAE specifications.
Most of the “standard corrected data”, or STP(standard temp and pressure) numbers you see posted by guys having their engines tested are for the J607 spec....... which is 29.92” baro, 60*, zero humidity.
What that means is........ if you were testing the motor in those weather conditions....... the correction factor would be zero.
The corrected and uncorrected numbers would be the same.
As the air density decreases, so does the power.
At 5000’ the air density is way less than sea level...... so the motor will make way less power.
To the tune of 20-25% less.
