I am building a street port rotary for my airplane project. I am in need of some advise on a stand alone ecu and what horsepower I should expect for this type of porting. I am in need of about 180 to 200HP so what do I need for intake and injectors, exhaust system, ECU. I have the standard rx7 oil cooler, and a custom racing radiator. I am thinking of a 90mm throttle body and over the top intake system that I have seen on other aviation installations. I have a Microtech ls10 ecu and the x4 that goes with it but is there a better ecu I should use? Which injectors would be appropriate for this install? Any and all info would be greatly appreciated.

 

Probably not the one to render an opinion on your questions, especially since I don't know which rotary engine you're working on and no experience with your planned use of it. I'll throw this out in case you haven't already seen it....

Thanks, I have those books and the problem is Tracy crook is no longer supporting the ecu for the rotary aviation but I do have his PSRU (prop speed reduction unit). I am using an 88 13b with medium street port and need to build an intake. I am thinking of using a 90mm throttle body and 4 injectors and wrapping the manifold over the engine that I have seen others do in the aviation conversions. I have been reading about the exhaust and would love to use inconel but the price is prohibitive. I plan to use 321 stainless in .065 thickness, and I believe this will give me an adequate safety margin. In Tracy's book he has a flexible stainless that he replaces after every 50 hours of flight and I do not want to have to replace parts that often so I hope the stainless is strong enough to hold up to the challenge of the rotary running at 6500rpms most of the time. Again thanks for the reply and any and all other info is appreciated.
