Not from my end...
shm21284 and I were playing with the center section alot but to no avail. I'm pretty sure you don't want a straight PWM signal controlling it, but a control unit will need one to time it. Does anyone know anything about its endurance?

 

the endurance, it looks like it wont last that long with rotary TGT's . maximum temps at which these turbos will work reliably is 1400degF continuous and about 1500degF intermittent. you could put an oil cooler before the oil gets to the turbo, but that really doesnt have nething to do with EGT's. And the control unit would be complicated as well, i think its set by RPM. The reason for setting it strictly by RPM is that the oil pressure varies in direct relation to RPM, and therefore effects the operation. 50% duty at 30psi oil pressure vs 50% duty at 90psi oil pressure probably give significantly different vane positions. And i think the turbo only has 500ish cfm flow? Theres always the GT42V tho???
