Inliners International Forums General Discussion Hi Performance Mighty six! I have a question

I believe you need to modify the intake port w/ the lumps also raising the roof would help.
If you just raise the roof that will not make up for the lousy short 90 degree turn radius, that is where the lump port helps a lot is in the short turn radius flow, along with filling up the port volume. Need to bring up the port velocity.
