How about a bigger hotside on the turbo? That should help.
Exactly, Justin. That's what I think, too, especially now with the larger intake and exhaust ports.

Yep, I did exactly that. That was one of the things I had originally planned on doing. It's hard to see from the pictures but I did angle the first set of short and long radii prior to the eyebrow cut. I believe it helps out substantially; I suppose we'll find out once the engine breaks in.

is that the difference between the old bp and the new one?

I was just down the road from Camp Foster on Kadena, I am now back in the US, and living in Delaware.

That's part of it, Mike. If you look more closely, you'll see the extend port itself is wider and a bit longer. Plus, the eyebrow cut on the BP is longer, wider, and tapered at the top.

Just finished putting together a turbo secondary bp myself this weekend and just cant wait to see what it offers.

Hey BDC you convinced me that was the way to go a couple of months ago when I asked you about the durability on this kind of setup.

Anyhow the pics are awesome, good job. Until Ito gets here to give you a grade I am giving you an "A+".
