The reason I have not been posting more info is because the sensitive nature concerning the nature of the build . It employs technology that I have never seen before . It has fuel air vortex towers and turbo mounted air to water intercoolers . The engine in question is a 1602 . It has a big bore kit for a 40 hp with a 74 mm crank . I figure that if two tinny turbos can make a Ford Eco- boost get great milage with 3.0 l dragging around a big pickup truck , I figure that this combination will make a great engine for a split bus . 30's technology is still very common in aircraft piston powered aircraft engines with modifications to the fuel and air induction systems . So the air cooled VW engine is the natural choice to attempt to make a bit better . 😉

And get this ; the fan cooling is a simple source of low pressure air charge . Naturally with this design it's only obvious to take advantage of that opportunity as well 👍

I have to machine the outlets for the water cooled intercoolers . But the mock up of all of the mechanical parts is almost complete . There are a few components of the fuel injection are to be mounted and wired yet .

Progress. It incorporates quad cyclonic sequential injection with dual anti backfire devices to prevent damage from a posable backfire . They will also double as massive blow off valves as well . I kinda over thaught this one ! Lol

This is getting more interesting all the time! I have not heard of anti-backfire devices...

They are actually more of a damage prevention device similar to a massive blow off device " valve" that is located on the secondary cyclonic chambers that are attached to each cylinder head . So yeah I have to build two of those to ! 😉

Couldn't you have done just one further upstream before the split?

Stand down @Dauz. You don't have to keep coming to this thread to argue about turbo distributor setups Confused

Oh by the way this topic evolved in to the mechanical fuel distributor that I ended up using instead of EFI or some other carburetor based fuel system . There is some very good input earlier in this thread in on getting the optimum performance out of mechanical ignition distributors though ! 👍
