I know the eaton is not efficient in high rpm, but every dyno I have seen (including mine) shows that our hp climbs fast all the way up to 6krpm, even with a 2.80 pulley. So I think that is just an excuse for something because if their stage 3 cams are the ones they are having problems with, then where the heck are the dyno charts for the stage1 and stage 2 cams? They were claiming 50-150hp just for the stage1-2!!
I don't know why they would claim that we could get up to 200hp with their cams, and then not back it up. Oh well, I guess we should have known better than to get our hopes up about actually having a shop make some cams that have been proven on the dyno to make power.
What you have to take into consideration is that the new cams are going to change the way the car breaths and how much air can get into the cylinder. With more lift and more duration the cam is allowing the cylinder to take a deeper breath. The same pump (blower) is going to have to push more air just to keep the same boost levels. With the eaton being just about maxed out already I wouldn't be suprised to see it running out in the upper rpms. Especially since that's where the cams are just starting to become efficient.
