several of us here have boosted itr's.

as many will tell you, it's all in the tune.

but i don't rape on my car every chance i get - i just get on it when i need to.

i run 10psi although it goes up to 12psi on occasion.

I think Alfonso ran like 15psi+ on his stock block, but he had a thicker headgasket.

High compression = instant spool!
