Turbo Nozzle Shrouds

Yes Don supplied the rails.
The Adel clamps are stacked to mount the tubes to the pushrod covers.
I’ve got my safety wire Adel clamp method down to a fine art now so there was only minimal cursing.
Not my photo but mine looks exactly the same as this photo.

I may yet relocate the rail outboard of the spark plugs.
The bend in the stiff short hoses places a twisting moment on the shrouds on the nozzles. The o-rings and spring setup appears to tolerate this but a straight hose I think would be better. I’ll ask AFP.

I'll bet these guys can come up with a good hose for that application.

The rail and the hose look great for a turbo installation, but for just providing ambient air pressure, looks like a simpler, lighter solution could work.
