Def a unique build, but cool. I really dig the explanations as to why y'all did what you did and specifics on fueling. Side note.. Recently ordered your titanium Y back and EXCITED about getting and hearing it on my G sedan!!! Hopefully some time soon, I'll be bringing mine down for a build. 🤞🙏

@1:50 You’re on the right track, but that’s not exactly how it works. You’re right in that increasing base fuel pressure to an injector will increase it’s flow rate (or as you say, “make it bigger”). But in the case of a manifold referenced return fuel system, the regulator’s increase to fuel pressure in response to the increase in boost pressure do not increase the flow rate or “make the injector bigger.” It actually keeps the flow rate the same as it was before the boost. Because that’s the point of a manifold referenced regulator. This is due to a phenomena known as “differential pressure.” Differential pressure is simply the difference in pressure between two given points. In this case, the two points are the fuel rail and intake manifold. Just like you said @1:45, for every one pound of boost increase in the manifold, you will get a one pound increase in fuel pressure in the rail. So lets use your example of base fuel pressure set to 53 psi. When boost pressure increases to 20 psi in the intake manifold which is at one end of the injector, and as a result, the pressure at the fuel rail on the other end of the injector also increases by 20 psi, your fuel pressure differential is still 53 psi, not 73 psi. Thats because the 20 psi increase in fuel pressure is canceled out by the 20 psi increase of boost pressure in the manifold. Leaving you with the original differential pressure of 53 psi. The opposite is also true. When the engine is idling with the manifold in vacuum, that same manifold referenced regulator is going to pull the fuel pressure down lower that base pressure on the gauge to maintain the 53 psi of differential pressure. That’s why you’ll see the fuel pressure sitting at 25 or 30 psi at idle instead of the 53 psi base pressure the regulator was set to. Make sense?

Is Fast Intension’s the best Twin turbo kit out for the 370?

Y'all have any experience with Nisformance oil pumps? Billet gears and backing plates with port work and shims for higher pressures. It's the last piece i need for the "while i'm in there" cascade triggered by picking up a mazworks pan and baffle. I think Nisformance is out near y'all too.
