I made a custom set of Huge Bore Butterflies for my ported intake. The prototype for the HBB's cost me $600.00 to make. I was hoping to make a group buy to lower the cost, but there was no interest. These HBB added about 18+hp and 10lbs lb torque on my naturally aspirated engine.
It took me a week to port the intake.
I imagine that on a force fed engine it could double the gain.
The HBB's are all made from aluminum billet on a cnc milling machine.
