a little overboard, but still nice job. I never really realized how porous the OEM casting was before seeing those pics.

between the runners. i thought the runners protruding into the cavity of the IM would cause turbulence when the air rushes in from the TB. so, i filled them in. im going to tape off the runners tomorrow and shoot glyptal on the entire inside of the lower IM.

nice work... but silly question. Wasn't the gylptal suppose to go INSIDE the IM not outside it? :-P

into the cavity..

Ah I see now good idea

That would also negate any helmholtz resonance tuning in the primary runners
