I doubt it is the low compression rotors. Matter of fact, the NA rotors and housings that I plan on installing to my street ported 4-port might even be quieter than the low compression turbo rotors, as they have the cast iron exhaust splitters. Time willl tell. Paul Conner

Would the low compression turbo rotors that Paul is using have anything to
due with the reduced sound level?

After hearing the plane last fall, I can tell you that both the sound
level & 'tone quality' are a refreshing departure from typical rotary
sound. If Paul finds that he's making adequate power with reasonable
fuel economy, he will deserve credit for an amazing 'find'.
