Hi,
My car (Rover P5B) has a Leyland P76 V8 engine in it. I've fitted a Rover
SDI exhaust manifold on the passenger side (cylinders 1,3,5,7), this has
twin 41mm outlets pairing cylinders 1&5 and 3&7 together. This then goes
from two 41mm pipes down to one 50mm one, and then into the rest of the
system (65mm single pipe).
The other side of the engine has a Rover P5B manifold on it, this consists
of all four cylinders going into one with one 41mm outlet. This then goes to
a 50mm pipe into the rest of the system.
The basic problem is this. due to the lack of clearance on the driver's side
(cylinders 2,4,6,&8) the other SD1 twin outlet manifold may not fit.
Are there any problems, apart from the reduced performance potential, of
having different manifold types on the banks of a V8? The SD1 manifold will
certainly flow better than the Rover P5B one. The car seems to run fine, but
I'm planning to enter a race in a few weeks, and won't have time to try and
fit the matching SD1 manifold to the other side.
The Leyland engine is fairly low-reving, maximum power is produced at about
4000rpm.
Opinions/ideas anyone?
Thanks
