so lets say it does get 18 hp at high rpm. no gains at low-mid range, so what would be your best set up as far as plenums are conserned?
Cosworth
SFR
plenum spacer plus lower mrev2
??????????????????????

If they insist on pricing it at $1200-$1500, Cosworth should definitely include the carbon fiber end caps/plates and the rest of it should come offered in either a powdercoat finish or polished to a nice show quality shine. I think that either would look kick *** and help justify the high price. Just my
.Can you and Sharif suggest that to Cosworth? I know it's probably wishful thinking at this point, but

If your willing to fork over the money, I would go with the SFR manifold easily. This is something for the high hp cars though.

That still seems a bit pricey for an intake manifold, especially for one that supposedly is only superior at upper revs/top end power. I'm still interested and anxious to see how it performs with FI applications.

I meant what was their thought process behind completely redesigning the intake manifold from the stock one. i.e. what's the science behind this feed-in design for an intake manifold as opposed to the factory (all increase in sizes aside)

This is a very complicated question to answer.... if you really want to know the answer you're going to need to know some serious math, etc. The question was pretty much answered earlier in the thread, and if you read some of the stuff posted here:

about half way down the page, you will find it's very complicated and math intensive. The documents posted are a good start to understanding this... it's not easy stuff. Specifically look at what Q45tech says.

I was curious as to the design and the why.
So Sad.
