The lower intake is lightly ported to match the gasket - the new blower plenum flange runners will also be matched to the gasket:


Nothing fancy here - just die grinder work, since I would expect most gains from port matching on a forced induction engine to be recognized on the exhaust side. Whether this helps much or not is not so important to me as the thought that I've done what I believed to be the best I could with what I had to work with.... actually, quite a bit of cleanup was done here.... maybe it was even worth it. <img src="/forums/images/graemlins/wink.gif" alt="" />
