318 draw through build

I think you need to forget header theory when dealing with a turbo as the turbo will be the biggest restriction in the exhaust, think of log headers versus tuned headers. tuned headers don't gain much over a log design when pushing through a turbo.
So cylinder #1 and #7 join up with #2,4,6,8 under the engine and then they all flow up to #3 and 5 and then out through the turbo.

Correct, but in a conventional turbo setup each bank merges into a common point and into the turbo..

The way this is setup gas from cylinders 1 and 7 need to make their way into ports 2,4,6 and 8. Which are also trying to get their gas out. All the power to the people doing the work and I look forward to the progress.. But I don't see it working
