Chip it would be a fun test. I'm pretty sure I'm leaving some on the table with my setup. I'm pretty sure some spacers to increase the plenum volume would help. The current setup all fits under the hood, barely. I just don't have any room to go up without cutting the hood. I refuse to do that.
A modern tunnelram should easily out power it, but at the same time I can't use all the power I make now. I have to slow it down or get bounced off the track.
