Q: What do you port or bore it to?

A: They remain 87mm to aide in ease of tuning; the inlet/outlet tapers are changed; the throttle shaft is thinned and the throttle blade is modified.


Yields 321-325% CFM increase in flow with no drivability or tuning issues and in most cases can be run on a stock tune.  It picks up 5-7 hp/7-9 ft lbs of torque with big gains and throttle response and mid-range torque that you can feel.
