I am using this formula for HP calculations I retrieved from Goat Rope garage.
[50070.56] * [50108.127]/5252
Engine Speed Sensor x Engine TQ Sensor / 5252 hp/tq cross point
The TQ is form Engine torque which is not matching what is in the channel which is higher. We all know these numbers are not accurate by far! While N/A it said I was producing near 600 crank HP which is a lie!!
If you look a the attached screen snip, you see the Engine TQ @ 1,032 but the graph only shows only 836. So not sure which sensor the HP is calculated from on this one, the 1036 in the channel or the 836 in the chart but either way, no way I am at that power with that boost. 836 TQ seems more close to reality at 11.5 psi. but looks as though the math may be using the engine TQ in the channel.
I know however that I must be at least making over 750 bhp at 9 psi as I had a BMW X6M competition try me while tuning and I walked away from him, by looking at power to weight calculations, I'd had to be at 750 at the crank. They are 617 bhp and about 600lbs lighter. The fueling is way better now and runs much stronger compared to then.
