Man, some folks out there could probably weld concrete to wood.
I am not one of them.
Looks very nice. Is that turbine section in the pictures part of the turbo you'll be using?

Can someone help me out by explaining why that collector doesn't let the high pressure pulse from #1 go straight through to the #4 runner and hit the valve about the time it's opening at high rpm, or just bounce back and forth between the two ports instead of actually going into the turbine? I'm pretty sure that's why Corky puts a divider wall between the #1 and #4 runners in his log.
I'm too lazy to figure out pulse speed at 1500F and 35 psia. Anyone wanna look that stuff up?

None of the runners point at each other. They all point to the same direction, towards the turbine. The merge angle is higher than I'd like it to be, but that's the compromise with a short runner manifold.

Can you think of a better spot for it?
There's only so much you can do with a short style manifold. Adding EWG will always disrupt flow. For best boost control, the flow must go in the direction of the wategate, that's why I couldn't use the bottom of the collector as a source.
