911 R style EFI high butterfly… it’s running video …..

Post by Madjad »

I thought I’d post the development of my injection system here

Having recast the 98mm high manifolds, I thought I’d add a injector boss, so the injector sprays fuel straight onto the valve, like the mfi and cis systems.

Throttle bodies will be 80mm high, with the butterfly 55mm above the manifold.

Air filters and trumpets will be the same as used on carbs

Looks very interesting. Are you developing the whole thing? - whatever that means! Fuel rail, linkages, electrics and ECU?

It will be a full kit, ready to bolt on. The fuel system is not being done with fuel rails, they are too modern in appearance. I want it to look retro.

Further development today, engine in and got the linkage working. Trial fitted the fuel distribution block, with built in pressure regulator

Can anyone lend me a rain hat, either fibreglass or steel, so I can get some amber fibreglass ones made?

Pictured with tall manifolds, and the prototype throttle bodies, with the injectors built in.
