We
decided to develop the 2.0L Duratec a bit further before the end of
2007. Simon, our cylinder head designer has done extensive work this
year on the Duratec, the original standard valve head has worked extremely
well but since then he has carried out further development & with
the a new high port head that we have found, this has allowed him to
significantly improve the airflow of the cylinder head. We have also
used a slightly bigger valve on both inlet & exhaust, this has gained
a 15% increase in airflow over our current cylinder head that we had
developed for our original 270 kit, but more importantly the airflow
that we have gained has not compromised airflow at lower valve lifts.
In order to get a exact result as possible, we took our existing engine
which had been used all season in the SBD Westfield, replaced the cylinder
head retaining all the original components we used from the first build,
then took the car back to Track'n'Road, where the car had originally
been mapped & with the help of the 2 Steves made adjustments to
the original programme on our MBE management system. We initially ran
the engine on 4 injectors, this showed 294bhp/189lbft, & then on
8 injectors which should 304bhp/195lbft. This showed a significant increase
of approximately 20 bhp over the original tests.

BLT-STUD-DUR-2.0L
Head stud kit for 2.0L Duratec. We have found on high output duratec engines that small amounts of movement occurs between the head & block, which causes damage over time to the faces & gasket. This will eventually cause failure, so by replacing the head bolts with a head stud kit, this clamps the head & block assembly more securely.
BLT-MK-STUD-DUR-2.0L
Main stud kit for 2.0L Duratec. With the higher rpm/load which comes from a tuned duratec engine, we have seen movement between the block & main cap cradle, which would be catastropic, so we have replaced the bolts with a stud kit, which clamps the block & cradle together securely.
