na like i said, mainly i want something reliable. like i said i think there may be some gains to be had by a higher flowing pump, but not my main goal, just reliability.

 

you'll want a higher flowing pump. Ralliartist should know this now. there was a large debate in some thread about his single pass manifold....with a dual pass, the higher flowing pump is optimal, and with his single pass, the metzer pump is almost considered needed to maintain equal cooling of air charges per cylinder
