actual comparison, 4 port vs 8 port

[tyrannix]

hoping sweedish Mike can chime in here

i would like to find stock for stock dyno charts (as finding identically modded cars is unlikely)

for <5k rpm on both a 4 port and 8 port head CA18 with butterflies working correctly.

just want to see actual numbers and torque curve.

anyone.... bueller?
