Here is a dyno sheet on the street RX7 called RX7.com.
boost is 28 psi and a Garret T78 turbo is used supplied
by GReddy. Also GRedddy supplied the intercooler and exhaust
manifold. The ignition system is by Jacobs Rotary Pro Pak.

Not that I recommend 560 HP in your everyday aircraft but it
should be good enough to beat most piston powered
aircraft at the Reno 15 minute kit aircraft races. 
Not bad for a 200 pound (less accessories & redrive)
two rotor.
