Thanks again Rob,
As we saw, the DP on the right with the small discharge hole would not be able to control boost. I have customers that bought that DP and complained they could not get the boost below 25lbs, the hole needs to be enlarged. To be able to control boost we have to be able to divert exhaust away from the turbine wheel, if the discharge hole is too small, we will not be able to divert enough exhaust. What bothers me is the thickness of the exhaust flange, it is plain too thick. I'm not sure how far out the flange could be ported and I am also worried the flange opening for the DP may not be able to be ported out to flow properly when using a larger Q or S trim turbine wheel. I give the pipe an A for appearance, it is prettier than mine with the polished pipe... but thats about it....
