Okay... First things first. No wrong info getting away in this forum.

1) The 02 housing is the best on the Market. PERIOD
2) The 02 has to have a custom DP made with a 3" V-Band
3) The dump DOESN'T help spool!!!
4) The 3" 02 housing post turbine exducer helps spool "some"
5) This 02 design uses the one and only JMF Flange that is the best design I have seen to date.
6) No boost creep at all on this design
7) If you want the best 02 housing made but this one

I have the first one of this design. However, I hade mine before Shearer fabricated one! Great piece of work. I think it will also work with A/C. Mine wouldn't because we didn't want a tight radial bend in my 3" housing.

The one I have we custom made and used a true 45 degree bend 3" pipe. It would not fit with A/C so I took it off. The one that Shearer made I'm almost positive works with A/C He had to use a tighter radial bend than a 45.
