E-Type F.I.A. manifold

Classicfabs have spent around 300 man hours, and over a £1000.00 in new tooling to design and develop, what we regard as the best performing E-Type F.I.A. type manifold available.
The geometry of the branch manifold intersection, has been mathematically calculated and 3 dimensionally computer drawn, to give the best gas flow possible, while staying within the confines of the F.I.A. CRITERIA FOR THIS TYPE OF MANIFOLD.

The following computerised drawings show how the design was developed, with its various stages. It also shows how it looks in stainless, and how it looks with a ‘Black Ceramic Coating’. We feel that to get the best performance from the manifold it should be ‘Ceramic Coated’ on the outside. We have already received orders for these from a top restorer of E-Type cars.
