Turbo cars like smaller port, high velocity ports without a lot of overall port volume (gmr head). supercharged cars like the bigger ports with more overall port volume. an sc engine dosent realy care about velocity its gonna shove it in and shove it out. the 85% rule for sc apps you want the exh to flow within a minimum 85% of the intake when you get your head to flow to that potential the power will not fall off up top near as fast if I remember infra's dyno sheet his engine maintained up top without falling off why is that because of that monster port on the ex side of the head and I bet ya a 12 pack that his head is actually flowing within or dam close to the 85% of what the intake is moving

I highly doubt that, stock heads flow 230 cfm on the intake, and the grm flows somewhere near 200-210, that port has to outflow the intake

Agree, but even using it as a percentage of gain.
The stock heads I flowed, flowed intake at 28" of water
230 iirc
Ex was 129,
With mild work on both
Intake went to 260
Ex 199
Both @.500 lift
