ZeroClearance,

Welcome! Excellent info!!!

Points of interest.

7200, and to a bit lesser degree the 7006 choke's or governs the turbos speed.

A larger compressor wheel slows the turbos acceleration (boost becomes more progressive).

A larger compressor wheel on a 7200/7006 will operate more efficiently (less heat more HP).

Can I add:

A larger compressor wheel can push more air at the same turbo shaft speed.

It takes higher exhaust pressure to equal or extend the shaft rpm over the 7200/7006.

Question:

Is the T3/K27 flange also a limitation? Or can a larger turbine with the right turbo extend your HP levels substantially?

At one bar boost what might we expect the pressure in the headers to be with a stock K27-7200 v a turbo with a larger compressor?

What is this effect?
