    Turbo sizing trouble

    Have you played with BW's matchbot at all? It's taught me a lot about turbo maps and how they relate to performance. I'm about to compound my 64mm version of your turbo, and math suggests that with a 97mm turbine you'll probably want an A/R around 1.32, or maybe higher, to avoid overspeed. But...

Compressor just because it was free and gives me reference to how to not do it (pretty sure the turbine A/R is to big) 60% or 100% sticks with more pumping. Wanted to go dual CP3, but that interferes with my...
