Thier initial retrofit performance kit was in the early 90s on the ford 5.0 EFI used in the mustangs...heads were roughly double the cost of highend performance heads...also I am unsure as to it's viablity with forced induction or seal maintainance.

Production costs even on a mass scale would not decrease you have fewer parts but those parts require FAR tighter tolerances and more precision machining therfore costing much more per piece to manufacture. If this was such a great idea auto manufacturers would have gone after it by now...given that there have been funcioning prototypes around for over ten years now

I actually think there was a post on here about this right when I signed up for zilvia and I am still pretty sure it is not a worthwhile design

and to whom ever gave me a neg point for my earlier comment eat me...
