When I was looking at extrude honing an exhaust manifold, something I remember from one of many threads I read on the subject was that extrude honing was best used on parts where normal porting was difficult/impossible. Someone said if you want to extrude hone something do the turbo housing.
So I thought about this. If you physically remove material I would think the effects would be similar to porting out the housing or clipping the wheel, i.e. more top end flow, laggier spool up ... BUT ... the poster suggested extrude honing the housing would reduce turbo lag /ubbthreads/images/graemlins/dunno.gif
