[QUOTE="Marty, post: 21774, member: 602"] Just trying to see what other people are running. I am measuring boost from the intake y mechanically, and I am measuring drive pressure from the EBPS location mechanically as well. At a steady 40 psi of boost, I am seeing 47 psi drive. This is with a S475/83 1.0 T4. It's pretty drivable with 400/600's, but I know I need more turbo for this setup as 40 psi of boost is about 1/4 throttle. Believe me, I'm already thinking 100+mm in the passenger fender well but for now I'll settle with this turbo. Either way, it's just a turbo to drive the truck around on... [/QUOTE]
