RE: Intake Manifold
That intake is really only gonna be worth anything when included with heads/cam. For my money at least, I can't see spending that kind of cash when I can get more out of a blower for less money.
As far as making it out of metal, it would be more dense and therefore store more heat - no thanks
For guys that are looking to put down huge #'s with a race car every ounce of power is an improvement. For the other 99% of us it's much too pricey. These motors nowadays are CAD designed and flow pretty damned well from the factory. 30 years ago 300 horspower and 25mpg was unheard of with 281 cubic inches

RE: Intake Manifold
I too would be surprised if it actually made a significant real world improvement. Besides, with intake manifolds usually the following is true.
Anyone that has built a traditional pushrod motor can testify that there are PLENTY of manifolds that will give you 20 or so HP over another good streetable aftermarket intake at the high end but lose gobbs of torque down low and have the low end throttle response of pudding.
This is the reason for charge motion plates. Not just emmisions. The whole idea is to have a manifold that makes torque at the low end, but opens up at the high end for the peak HP. Porsche uses this system on their flat 6 motors and it does wonders for flattening out the torque curve.
Even camshafts. There usually is no such thing as a cam that makes more power everywhere compared to stock with absolutly no comprimises. That is why we have VVT.
