Hmm, I will have to do some more research on this, from everything that I have read and seen a velocity stack has always increased the flow to the chamber.

Any idea what work you might have found this in? You have spiked my interest!

And yes this would make it alot simpler to make, though i would still put a pretty serious roll on the inlet if it was flat to the floor.

Todd was talking to an individual from on of the Supercharger companies I think, and it as also mentioned as a good solution.

BUt there is tons of chatter on this specific issue all over "De Google"

Brendan,

Why not just "flatter" the original 928 Developments intake with the Ross Machine Racing bits. The 928D intake had separate plenums, and cross runners. If memory recalls, the actual design performed well, but the carbon fiber did-not. Seems like an aluminum replica would solve the problem.



Also, it would be theoretically possible to run the intake on stock 928 management, ala Dave Roberts dummy maf in his supercharger kit.

Thanks Hans.

I will be map based, so I don't need the MAF stuff

Also, those runners are simply too large and too long, per the engine simulator. If course I COULD be wrong.

BUT, that said, my plan is somewhat similar, as it has the two plenums with 4 feet each, fed by their own Throttle bodies. But I will have them connected by a large volume area.

The other thing about Phil's manifold there is that there is no balance tube between it.

Do you have any info on it, is that Scott's old car ? I think he made that
manifold 4-5 yrs ago, he sure got a head start on the rest of us ! Do you
have anymore pictures or know who owns the motor now ? Thanks for
the pic...

Very interesting manifold, however for me, I want to get rid of all that piping running out the bottom and back.
However I would be keen to know what they did with the oil filler neck.

Emachine shop can't do the angled entry hole for the runner past the paralell to the head flange. So I downloaded Alibre. Which I have no idea how to use.

I admit their 3D software horribly suck. It's so limited!

Alibre has a steep learning curve, I will say that.
