Home Made Plenum (Comments Wanted)

[Legend]

spigots /ram tubes need to be like the std ones and trumpet shape into the plenum

So you used 53/54 mm pipe to mount to throttle bodies? How did you make the trumpet shape?

If I dont run a trumpeted end will the air flow be disturbed or something?

Spoke to the guy today about the trumpeting and he thinks it may be difficult to flare the end.

Has anyone used 51mm pipe for the plenum and then run a silicon reducer from throttle bodies to the plenum?

Looking good.

Leonard.
