Okay, this isn't going to be anything as basic as how to read a compressor map; I already have a fair idea on that. Part of my question is in regards to... well, I'll use Rice for an example, as he has that shiny new T-51. Now, I know HKS offers it in a couple trims, and it's been called a Garret turbo... I'm wondering if it's possible to find a compressor map for it. Or any number of other things, really... which leads on to another question sort of. Is it possible to get ahold of maps for the TA45 (or TA-whatever) or is it just another naming scheme for a standard compressor?

Anyhoo, that's it, thanks for reading this far.

 

Well, back from the dead....

Yeah, how do you read those things.

I have found how to use one.........for a piston engine.

Any luck man?

 

Use the piston method but double the displacement of your rotary before entering the equations. In other words, a 13B is 1308 x 2 = 2616 cc = 2.616 L. For cubic inches, the 13B is 80 * 2 = 160 CID.
