Trq per # of boost?

[rotax]

Is there a way to calculate / guesstimate trq gain/loss per # of boost?

I've accumulated that HP per boost is 8-10 per #. Depending on efficiency and who you talk to, super vs turbo and so on..

But I have not seen anything for the same calc for torque.

Anyone?

Should follow?

Torque increases should follow HP to a point as torque is a product of HP and RPM. I know the two will seperate as volumetric efficiency and parasitic losses begin to figure in. Interesting to know if there are calculations available to incorporate these and other variables.

(rpm x HP) / 5252 = ft. lbs. torque. For example 100 ft. lbs. is gonna pull just as hard at 5000 rpm as it will at 8000 rpm even though there's a 50+ hp difference. Torque being equal the higher hp engine will accelerate longer and close a long enough distance faster.

What I found, and came out correctly was (5252 * <HP>) / <RPM> = torque (ft lbs)

Thanks for getting me on the track tho
