I can see that an extra free 5HP would definatly be nice especialy on a van. I'll have to try out your sugestions. Wish we all had access to a dyno it would be fun to see actual results of such labor.
I'm lucky...sometimes. When i was playing with this stuff a few years back...my brothers shop and one other where a friend worked had lotsof spaces in their dyno schedule. Now I am several hundered miles away. It will cost me now. Ray
