Something similar to the Ford / Yamaha SHO plenum might be interesting. Long runners on the primaries and short direct runners for the secondaries. Hood clearance would be a nightmare, but that engine ran extremely well for 3.0 L.

Yes it did!

Re: Frankenplenum
 

The nice thing about the removable top is I can try several different things...divided plenum, reduced runner length, air horns/stacks...maybe even a clear top just for shits and giggles

Re: Frankenplenum
 

at BG when kirchoffer fired up the cammy 421 we could see the top which looked like it was made out of a 1/4 plate of nice alum (about 2 ft by 20 inches or so) would flex and pop like a beer can

it was pretty amazing, but it didn't deliver the big hp hoped for and it was a solid looking design with nice taper built into the runners, injectors on the outside, and a big plenum box

I'm more enamoured with the look and audaciousness of the cross ram individual throttle body

those big caliope stacks bring back memories of screaming big blocks at the drags in little altered cars and some door slammers only the blower cars were cooler!

the injector housing creates a rather torturous path with the s bend

cutting up and rewelding the OBX would be a major chore, but it's cost effective would look like the corvette racers (which have beautiful carbon fiber cross rams)

with the 3d printing technology, we could print up and individual base and then cast it. with the right media, like a heavy nylon plastic, it would probably work right off the printer with a heat insulating gasket

anyone want to give this a go? tuning will be tough, me thinks the megasquirt piggy backed into the factory ecm to run the spark and injectors would do nicely there

I may yet try one of these on my c3 to see how well it works out on a little screamin 4.8 iron block

the short stroke revs up nicely and the car is light enough to make this work

cheers!

Lee, how about a photo from the front and side Horizontally to show the height.

Re: Frankenplenum
 

I will get one, have not picked it up yet...put it should have added 1/2 inch or so...will get some this weekend

Re: Frankenplenum
 

It looks like you are building or modifying the intake just like this ZR-1 that is in Japan. Keep it up, I'm watching how it turns out.

We will address cosmetics with epoxy at some point to make it "prettier"

I matched the curve on the back with alittle finesse and a vise

The runner no longer is part of the wall at the top which will help flow also
