Exhaust gas pressure with a turbo

Just a note of caution, at around the 37-40 psi point you can't keep those Purosil hoses clamped down. No matter what kind of tube bead is under there they will blow off. If you go that high you'll need to go to either Wiggins couplings or Marmon V-bands. On the HGTS above we went to V-Bands because it was the easiest for us to customize and make custom flanges or adapters.
