There's an old paper on the CAFE web site that talks about exits; t= hey say that a 'bluff body' (what you typically see on the belly of= an RV-x), with rounded approaches to the hole, is the most efficient exit = method. They talk about gills & say that every blade of the gill adds d= rag, so it's better to have one opening. I suppose that if the face of = the radiator core is close to the gill location, that might change the equa= tion a bit.=C2=A0

You mig= ht want to do some research on rtv before using it on the intake. It'll= probably work fine, but if there's any chance of gasoline getting on/a= round it, the gas will attack it. Squirt some out and let it cure completel= y, then put part of it in some gas, and suspend the rest of it above the ga= s in a jar, & watch it for a few weeks.=C2=A0

If it were me, there are other sealants I'd ch= oose over rtv for anything around gasoline.

FWIW,

Yes the flange is also on top as i planned to = turn the 13B =C2=A0- 90 degrees ( plugs up) so the intakes stand upright.Th= en the TB (Throttlebody ) face the inlet duct.Want to make use of the "= ;ram effect " of the incoming air to the TB and filter.
This makes the hot exhaust easier to exit with= out complexity in turnes and bends underneath the engine.
Side radiator with "gills" on the si= de for hot air to exit on the side of the cowl.Think that the "suction= effect" of the laminar flo of air over the vents will help with the p= ressure drop inside the cowl.
Well this is what i planned and want to do..
The proof is in the pudding and must be tested= first.
There is always a compromise, if i want to do = one thing then must give up on another.

Don't see wh= y it shouldn't last:
1) It's round (assuming end opposite throttle body is a hemisphere)
2) Fiberglass doesn't fatigue like alum, right?
Weak point would be at the flange. Are you planning on using RTV or some ot= her adhesive?

I'm at the point where I need to construct the plenum. However the flan= ge moves it closer to the engine. Maybe I can I can put the removable cover= on top?

What is your predictions will it last on the rotary pulses ?
8 layers of bidirectional cloth the "pipe"
