I was told this same thing by RRE, Pruven Performance and other shops but everytime I say that I am told i spread wrong information. I am not doubting when Hybrid sees full bost, however the reason he says it is another story. Either way BB turbo is not needed to it 11s and it is considered a high maintenace turbo anyway. Get either a 50 or 60 Trim which are considered friendly pump gas turbos and you will be fine.

Exactly, ive been told by numerous places that build turbos that a ball bearing design actually dosnt help spool up AT ALL, but no one wants to believe anyone because its the biggest spread of misinformation ever.
