If the turbo can handle 7psi of boost at altitude it can make the same 7psi of boost at sea level turning even fewer [turbine] RPM. The engine can easily handle the horse power, and you have additional brgging rights. Dave Leonard -------------------------- Shhhhhh, that's my ace in the hole for next years Shady Bend race :-) My initial thought is to make the boost control completely manual at first, with the default being off completely. I can play with different boost levels during the test flight period, then perhaps set up a more traditional wastegate actuator at a pre-set level. Cheers, Rusty Turbo 13B powered RV-3...
