Nice job Wayne! Did you get the bottom turbo hooked up to the stock exhaust like you thought you could?
Oh, the vp we talked about had the seal pushed out of it when I sent it to Area Diesel. They fixed it no cost. Good people. First one they had ever seen!

On the S-400 turbo i machined the 5" exhaust flage to a 4" 3rd gen and used the 3rd gen cast elbow. so the S-400 is in the stock location. I dont have stud in it didnt have maby this week :ft:

Sooooo...you're using blow off valves to control boost??????

03-30-2009, 08:54 PM
My blow off valves are there for safety on the head gasket, these twins with the wright fueling could range from 60-psi to 90-psi Im running around 55-psi with stock CP3 and stock injectors

Those twins like sweet buddy, couple questions for ya. Which exhaust manifold you using? Why you not pushing the boost up past 55psi? Have you oringed the head yet? Which ARPS you using? I can't wait till I get mine so I can mod it up some.
