Driven Fab Mivec Housing Evo 10/RA

The factory cast aluminium MIVEC housing used in the Evolution X is a component that is prone to failure, most commonly due to a drastic drop in oil pressure causing the internals of the cam gear to slam on the casing. Or at times where valve spring seat pressure is increased.

Driven Fab’s Billet MIVEC Housings are made from a solid, high strength CNC machined slab of 6061 T6 billet aluminium, offering a significant increase in strength which in turn will help prevent the chances of failures of this kind occurring.

What causes a failure?

There are a few different reasons the housings can fail:
– Most housings have seen failure when the stock valve springs are upgraded and valve spring seat pressure is increased
– A loss in oil pressure causing the internals of the cam gear to “slam” on the casting

By making the cam gear housing stronger and out of billet aluminium, this eliminates the chance of failure due to a porous aluminium casting.
