Usually in a old fashioned piston type engine, for every 1psi you run you get around 10 more horsepower.

Is this different for a rotary? Do you get more power for each lb higher of boost?

I have noticed through some testing on my friends cars and my own, it seems almost like the rotary makes the same power at 1 psi that a HP equivalent piston engine makes at 1.5-2 psi depending on the engine.

I think that is because of the rotary motion of the engine, it allows the engine to take advantage fully of the air flow "pushing" the engine around. ( our engine just keeps turning, but piston engines pistons need to stop and change direction every time...less efficient for HP gain )...however, we still produce more heat.

At least that is my theory on it.

It doesn't work like that. The amount of HP produced depends on what the engine produced to start with, and then increases with an increase in mass airflow, not necessarily boost.

Uh Prax I suggest you read Maximum Boost like Evil Aviator said, and stop pulling numbers out your ***.

Those Ford 2.4L turbos must be Fing fast. They can push 18psi, stock.

My street ported TII from RP, with Garrett T04S04, did 13+ rwhp per pound of boost OVER about 10 psi.
