Does anyone know the max boost level for the RX6B or have a link to it's efficiency map? I tried searching the internet and came up with nothing for the RX6B. TIA

 

Here's the map from the 2000-2001 APEX'i catalog. I realize that it is missing efficiency lands and the units on the x axis are not what we're used to, but it's all I've got.

 

Here are the wheel sizes from the catalog, too:

 

Thanks Max, you wouldn't happen to know which compressor is used for the 7?

Never mind, I just found the compressor info (TCW76).

If I'm reading the map correctly, the maximum flow (in cubic meters per min) is achieved at a pressure ratio of around 3.7 which translates to more than 39 psi. That just doesn't seem right for a small turbo??

 

You read it right, it's just that the 13B will flow a lot more than that at 39 psi. Figure out what your PR is, how much the engine is going to flow at that pressure, and see where it lands on the map.
