Inliners International Forums General Discussion Hi Performance Idea on the "lump port" design

John,

This is a good concept, but you need to remember that the floor of the intake chamber is opens up as it gets further from the intake port opening to the manifold.

When you install a PES lump, you have to turn it sideways at an angle to get it in because the portion that creates the radius around the intake valves is considerably bigger than the portion that sticks out of the intake port.

As such, I am not too sure that this concept is practical as it would be almost impossible to install.
