Here it is w/o the turbo on yet..



Oh and n/a this thing made 218whp on a mustang.. The large plenum makes some very interesting peaks and valleys in the fuel map, so it was a bit difficult to tune though.

 

218 ... wow what kind of porting do you have done. Any graphs by anychance?

 

Small bridge on the secondaries, sleeved exhaust ports. I have a hard copy of the graph, need to scan it though..

 

Any reference to the source regarding lack of stacks for turbo applications? I have been intending to build version 2 of my intake manifold, including stacks. If it's true stacks are not a good idea for forced induction, I'll stick with what I have which already has bell mouthed runners...
