I'm looking for lb/min (or CFM@PSI) exhaust flow numbers for the 9K RPM engine. Ideally, I'd like to find a graph or chart showing these numbers over RPM so I can start shopping for a turbo. I've gotten sick of waiting for a kit that does (or can easily be made to do) what I want, and it's time to start thinking custom. This means having data so I can chose turbine and compressor sections based on logic rather than the latest hype.

So anyone know where I might find this info. I'd be willing to wade through SAE papers even, I just don't know where to start. I tried a search and came up empty, which is pretty much par for the course for me and search.

This is a good thread to start in. It's got lots of math but also deals with turbo sizing.

Thank you.

It appears my search ineptitude, as usual, is a result of know too much and too little at the same time. Just more evidence that, as of yet, computers are no replacement for people.
