Compounded in boost. And with that late intake valve closing point, the manifold would want to have that thing at 8500+ rpm.

Im sure you would be MUCH better off with a TBSS intake manifold, right cam, plumb discharge pipes into a A/W intercooler like the marine procharger kits use (like a racecar air/water) then into the TB. Tons better low midrange tq, less heat soak from manifold (your not only cooling off charge air with that setup your trying to cool engine block heat soak

The engine doesnt know its in a boat. All it knows is backpressure, manifold wave tuning and valvetrain dynamics and that setup doesnt look like it would make it very happy. Wait is your wideband between exh valve and turbine or after turbine?

As far as the TBSS intake and mine heat soaking I'm not seeing any of that, maybe I'm passing enough water at idle for that not to happen, but I data log both Ampient and intake air temps and at idle I'm usually seeing intake temps about 5 degrees above lake temps(mid 70's) and when on boost I'm seeing no more then 10 degrees. I haven't seeing what intake temps are before the cooler only after. To me this seem pretty dang good. I actually ran the boat this fall when lake water temps were 40 degree. At 5700 rpm and 7.6psi of boost I was seeing 44 degree intake temps I don't see any car/truck getting those kind of intake temps on a turbo vehicle.

If I can get a cam that wont revert water I can change my after turbo exhaust to get rid of that sharp swept back that's why I'm all ears if you can recommended a better cam.

Have any recommendation on cam?????

We can take this to PM if you would like so we aren't mucking this thread up.
