90 degree racing manifold.....

correct me if i'm wrong, but shouldn't intake manifolds like these be a little more curved from the plenum into the runners? isn't a sharp 90 degree turn horrible for performance?http://store1.yimg.com/I/machevo_1862_6439780

Yes.
Yes.

I think you need to understand that in this case:
Racing = lacks all smog provisions and can't be driven on the street.

It might make more power then a stock manifold but not as much as if it had proper radii and equal distribution.

Don't forget that proper bell mouths are expensive.

Well, the runner's would actually be a lot better IMO if the plenum was bigger to allow for better flow distribution.
