I have tried to follow this thread, but seem to getting lost in the buy now cost debate.
what is the purpose of spacing the plenum from the head. Will it increase air speed into the cylinders of add volume what does it do.
It appear to be a CNC milled plate of about 10mm . The BHP says 2hp on the dyno, you can get that with a clean polished car.
where is the magic ?
can someone explain the principle please
