Regardless, should I:

1) Knife Edge
2) Knife Edge & Coat
3) Neither



I vote for neither

Why? What experience do you have with porting turbine housings? The list of why's could go on and on ... I'm looking for some education here, not simple yes/no answers.

My theory is that if I knife edge the split bar in the housing, I will create less turbulance in the turbine housing and smooth out exhaust flow. I am hisitant because thinner metal will get hotter MUCH faster than it's thicker counterpart, thus why I would want to coat the turbine housing ... that and more importantly to lower underhood temps and lessen the possibility of melting some underhood wires & help heatsoak the engine/intake air/tubing.
