No I did not use lumps in the intake.

A port 1" wide by 2" tall has a cross section of 2 sq. in.,
2 sq. in. port will support a :

230 @ 7000 RPM
250 @ 6400 RPM
292 @ 5500 RPM

after this RPM the port will go sonic and VE will drop.
this is a rule of thumb, you really need to measure the air speed
to know what it is, you do not want to go over .6 mach
