Yeah, admittedly, I am searching for a way to have it normalize itself automatically as it does with the APC. I just think it can be done with automotive components which would be a heck of a lot cheaper simply because I wouldn't be using certificated parts. Like, I'm sure if there was a need in the automotive world met with an APC, that the APC would cost about $100 or so. It's just not that complicated of a piece of machinery. Like, a hartzell wastegate @ Aircraft Spruce costs $1829. The same thing (roughly) in a car application costs about $200. That's ridiculous.
So, my mission is to develop a turbo-normalizing system for experimental aircraft that uses nothing but automotive industry parts. I know people use Subaru Twin Turbos in home-built applications, but that's not TN. That's TC. The main hurdle I have experienced is, I have talked to several racing application people I know around town in person about it. People who sell aftermarket turbo systems, etc. As soon as you say the word "airplane", they clam up like they don't know you. I'm guessing liability issues, and I get that.
