Seriously though Tino, and this is after everything I've read in this thread, on these forums, and everything I've seen you do.

Do you really think you'd outflow that Cosworth manifold?

Lets not forget what sort of power Gareth's car made on the STOCK manifold, it was huge....plenty of cars in the states making silly power on stock manifold also.

The Cosworth manifold flows MORE than the stock manifold....15% more!! It's also PROVEN, and plenty of R&D has been done already.

Why not save your time, money and headaches, and pick up a Cossie manifold? its cheap compared to a custom job too!
