When it came to designing the new top spec engine, we knew a lot of effort had to be put into producing over 300bhp. We spent 4 years testing & developing components until we managed to produce this new high spec engine kit. We also wanted to make sure the kit was reliable, we had to develop special valve springs in order to cope with over 13mm of valve lift, regularly rev above 9500rpm & a safety margin to cope with potential accidential over-rev. We had a custom spring made at great expense, being made from the highest spec material, made in a dual rate which is also put through many treatments to extend the life of the spring. We designed a special 2-ring slipper piston & long con-rod, this showed a 7bhp gain on our development engine on its own. |

The MBE9A4 comes already programmed & ready to use, however with this level of specifcation we would recommend a mapping session to fine-tune the engine. The kit includes a coil on plug wiring harness. The kit itself also contains the necessary components to achieve this horsepower with a few extra safety features as standard e.g. up-rated flywheel bolts, main cap studs, head studs & up-rated bearings.

We
have been testing this on standard Ford crankshaft with no issues
, but those who would prefer could upgrade to a steel crankshaft
made for us by Arrow.

Matt Downer has been running our 2007 Duratec engine in his Escort during 2008. He has the 4 injector set-up producing 294bhp & has been enjoying the car at various track days including treating Simon Wooley - Editor of Classic Ford - to a white knuckle ride! He was featured in Classic Ford June 2009. |
