Re: Frankenplenum
 

I wonder if eliminating the common plenum entirely would be of benefit? This would require 8 t-bodies. and 8 velocity stacks. I always wondered how those systems on teh older hot rods really worked. Individual runner length is easily individualized.

Complex as all heck, but would look cool poking through the hood!

Re: Frankenplenum
 

Yup! A sheet metal box(s) with shortish curved (funnel) runners... I haven't crunched the numbers yet for the runner/air box dimensions yet, but a Toledo hood (or the like) is prolly going to be part of the answer.

Re: Frankenplenum
 

I wonder if the runners are hitting, I am only raising the box...

As far as run a velocity stack setup, shorter runners make it more difficult to keep the car at idle.

Re: Frankenplenum
 

It makes me happy to think that an aftermarket plenum may one day be made available by a savvy member of the brotherhood that will give our cars even more umph. :happy1:

Re: Frankenplenum
 

I'm one of those people. They're still on there. The spacers are only 1/4", and it does rub enough to take the under hood paint off at the front.

This sounds like a job for one of those 3D printers...a big one that can use some heat resistant plastic.

Re: Frankenplenum
 

What part of the plenum is rubbing?

Re: Frankenplenum
 

Pete used a Hogan sheetmetal plenum on Kevin's 441 several years ago. I believe it really didn't offer much improvement.

Re: Frankenplenum
 

I wonder if the volume was sufficient...also velocity stacks might have helped flow....intake runners that share a wall with the plenum generally have flow opportunities....

Re: Frankenplenum
 

But that Hogans was a short runner intake.. Lee is looking to keep the runners as they are and expand the 'box' if I understand it correctly

Re: Frankenplenum
 

Correct, in terms of the plenum volume I had 2 Engineers from the program tell me thats were the most potential was; and in looking at intake development on Porsche, Audi, and the Coyote motor I saw comments on flow improvements on "unshrouding" runners from an intake ceiling/wall.

I will also add that there was a ZR-1 race car with a raised roof plenum in another country with a documented 15hp increase due unshrouding of the roof side of the runner.
