Interesting theory.

One thing though, would you be able to tell me how you calculated the divisor value of 9402 for the power/torque equation? (opposed to 5252, or 16500/pi for imperial values)

When i converted HP and lb-ft to kW and Nm, i came up with a conversion factor for the divisor of 20/11, yielding 9549 (or 30000/pi), so i'm interested where the discrepancy between the two lies.

ie:
HP = (lb-ft x RPM)/5252

and since
HP = 1.34 kW
lb-ft = 0.737 Nm ... 3.28/(0.454 x 9.807)

we have
1.34 kW = (0.737 Nm x RPM)/5252

Therefore
kW = (0.55 Nm x RPM)/5252
kW = (Nm x RPM)/9549

Regards,
Liam.
