yeh i could be wrong, but i cant really remember but i did measure it.

idle difference would be from duration, your cam would have alot more duration than steves.

It certainly does, but there is a sound that comes from lift also, as having more lift for the same duration generates more overlap. The dev5 cam is certainly much smaller than whats in my car....I have no vacuum and no real boost until 3000rpm then it hits like a hammer....steves comes on more like 2500, and rolls on a little more, there certainly worlds apart. When I get the high stall I'll be going slightly under the 3000 mark, as I'm thinking I want a slightly smaller cam, I have low enough compression so I can always make up duration with boost, besides I no longer need the dynamic reduction in compression either.
