i have the rpm kit now and im pretty happy with it, but like, most of us here i wanna go faster but i dont wanna jump into the offshore kit. does anybody know of any upgrades that would work well with the rpm kit?

Also... what's the MSRP on the new RXP X?

i cant believe that no one has ported cylinder heads for these engines. if there are any shops out there, who does um ?

It's been done. You don't hear much about it due to the minimal gain for a lot of work and $$$. It's similar to extrude honing the exhaust manifold.


MSRP on the RXP-X is $12,999.00.

RC what kind of gains with extrude honing the exhaust mani ?
