My PWM IAC Mosfet failed about a week ago. Looks like it is stuck on, as the IAC gets warm fast and it idled at 4500 RPM. I am currently running with the idle set screw run in all the way for cold idle, but I idle at about 1600 RPM warm. I have a few spare IGBTs laying around and was wondering if I ...

They want you to post this at the MSExtra.com forums, as they refuse to even help troubleshoot. I got my answer in the MSExtra forums in about 40 minutes.

No worries about aircraft safety. This is planned to be a stationary generator running on B-100. I can get more power extracted out of the Turbine than I can out of a stationary small diesel engine.

Is this possible, Can MS deal with VERY high (150,000+) RPMS? I'd imagine the fuel table would look very odd, and the MAP sensor would be useless aside of monitoring EPR. Could you also make a safeguard with an EGT sensor to shut down or throttle back the engine if the Turbine Inlet Temperature got ...

OK, i figured it out. The Idle Valve is not closing off idle. When I unplug it, it does not leak all the way to 45 PSI (tested on shop air). I'm thinking i need to look closer at the idle settings. I might have it in open loop......

The IAC is running to atmosphere since I cannot weld aluminum. I am using the IAC off of a Ford Crown Vic, which has a 5/8" fitting on one end for a hose, and that is running to a breather filter. The valve seems to be being blown open, acting like a blowoff valve at boost above 10 PSI. Perhaps I am ...

Seem to be running into an issue where the Idle Valve is being blown open under boost. Is anyone else running into this.
