External Wastegate placement

[Lance]

I looked at the external wastegates page; pretty interesting. Is anyone here running a gate on the EGR hole? This would be most convenient for me. What's everyones thoughts on that positions ability to control boost? Good or bad idea? I notice many put their gate on the crossover pipe, and I don't see the EGR hole as much a difference with the direction that the exhaust flows.

The EGR hole works great. Just make sure you bore it out to the proper size for the WG you are going to be using; keep the transition smooth from the WG and EGR hole.

It controls boost perfect, no spiking or falling off (I was using an older profec B boost controller).

Doing it that way only vents the passenger side bank of exhaust, but it still works just fine. If you wanted it done "properly" where it would vent both banks equally, you would need to put the WG where the turbo flange is on the drivers side manifold. This is where both sides of the exhaust meet (the z31 exhaust manifolds are chambered for each side until they meet here). Rick88ss has his WG positioned here.

Ahh, Just do it!

Turbonetics NewGen wastegate. Has a full 2" inconel swing valve, rated for 1000hp of boost control.

I ran my Tial 38mm off of the EGR Hole and had absoultly no probelms controlling 21PSI from my previous T04R.
But the ideal place to place a wastegate is one where it draws equally from all Cylinders.

AND... at the most shallow angle in the direction of exhaust flow possible.

Yes, that is appropiate.
However, when you think like me....Size does matter and can counter that angle issue to some degree.(oh...sarcasm!)

I suppose if you are big enough you can get at any angle! lol
