Just want to make sure I understand your statement. Are you saying this turbo can hold 45psi of boost at redline on the N55? 30psi at redline?

It is accurate to say that this BB CHRA is happy to make higher boost, as in 30-45 PSI would be ok, and it would run efficiently. A JB CHRA wouldn't be happy at 45 PSI and at those shaft speeds, it would probably fail quickly. JB CHRAs loose efficiency at high shaft speeds at a much higher rate than JB.

These are basic turbo facts that are not specific to our products. You can research the question and corroborate this from many other sources.

As to what this CHRA will or won't do specifically in an OEM N55 turbine housing is a different question. The turbine housing is small compared to a TD06H turbine wheel, it will act like any other turbo in a small turbine housing. It will make the turbo respond quickly, but limit flow; therefore, the topend will be limited.

Did you guys also improve on the exhaust manifold, or is that still stock?
