I'm planning to use a turbo on a 20B, primarily as a muffler, but would like to set it for 3-5 psi boost.
A lot of current techniques are based on street car experience, which are not always directly applicable to airplanes, ie. no need for rapid throttle response (usually) and run at high % power continuously.

I'm thinking of a setup modeling refrigeration techniques:

 * Run all exhaust through turbo, no waste-gate, larger A/R
 * Compress higher than needed, which makes air very hot
 * Run through intercooler, which is more efficient with higher temp delta
 * Allow to expand using larger pipe and blow-off valve to regulate
   pressure before intake

The result "should be" cooler intake air at a slight boost.

What am I missing?


Thanks,
Patrick
