After a cheap 180

[lawrence-zs180]

nothing daft because im keeping the standard internals on this one so 230-240 at 4-5 psi.. if this works though im going forged and bigger and aiming for 300bhp at 9-10 psi.. maybe still gotta work that one out though.. oh and do the first one haha

If your gunna turbo it have you looked at using the old rover v6 inlet as this dont use the vis motor and would give you a more reliable power plus you could proberly get away with 7psi and could see 250bhp

The metal inlet manifold as fitted to the rover 825 kv6 DID use vis valves, albeit of different design.

The supercharger ran 5.5 psi and made on average 245-255bhp.
