Hi Alex,
BMW purchased back 2 Cars as
they realised that they were
selling cars with their ''P60 B40'' engine in.
Flat Plane Crank, different firing sequence,
No Vanos, not for the masses !!!
P60 B40 is a MS Evolution of the Mader engine,
whereas P65 [S65 Race variant] is evolution of
the S65.
Road GTR was ''detuned'' and also had a
restrictor in the plenum and was rated
at between 360/380 BHP but more like
400/420 in the real world.
P60 B40 in full race trim without restrictors will
do over 500 BHP as you say, but the
the restrictors for ALMS rules give around
440/450 BHP tops, and approx 360lb Torque
361lb to > Nm =481, which is the real
reason Porsche got the arse ache,
and also why all these alleged 430/450 BHP
S54 's are more fiction than fact.
Regards,
The Gorilla.
