If you are talking about like a port and polish job, then I'm sure it will be of some benefit. It would probably be very small though, and you might not even notice it... The BP-26 manifold is not really a high flowing piece. It has some pretty sharp turns inside.Originally posted by wilo View Post
It would be neat to see a back to back comparison if you do though. Compare numbers before and after porting/smoothing out the manifold.Tyler has spoken -
