But even with forced induction, you still have pressure waves bouncing back and forth through the primaries, so it seems like they could still provide scavenging.
But maybe the smaller pipes required to accomplish that do more harm than good on a blown motor, I don't know.
Neither do I (know). I was hoping someone would have some solid data.. All my books, and all the Vizard crap I read is all based on naturally aspirated motors. One book I have makes a mention "Size and length are meaningless on a forced induction engine, however blowers do not like back pressure therefor larger pipes are better."
Larger than what? My finger? Ugg.
I wouldn't mind but the difference really is nearly double the cost.
The other option is I can buy some used 1 3/4" hookers off a forum member for about $250, and have them ceramic coated locally for another $200, and another $50 or so for reduces and I'm around $500.
Or I can buy 'painted' 1 3/4" hookers for $430, and have them coated locally, reducers, etc for about $675 or so.
