Wonder why type A cams never get much consideration? To date my smaller 2.7L is producing 20psi on 98ron earlier than 2.8L's on E85 with the same turbos. Which is something to think about. I get positive boost from 1,500rpm and starts pulling from 2,500 rpm which is where you want your cams to operate.
My boost plotted againt Paul's and biggest difference is cams and lack of head work on my part.
