SBJD exhaust manifold September 24, 2023 12:44PM
466 JD question is which exhaust manifold works best ? I have a front discharge manifold from a combine that gets the turbo up front out of the way. Also have a 7810 mid mount exhaust manifold that puts turbo right over valve cover. Would need to remove turbo to check / adjust rockers / etc. Which makes more power ?

What I do is I take 7700 natural manifolds and make a plate with a vband on it that turns in 90 degrees so the turbo is facing forward and if level with the head, makes things easier to work on

I have 3 hotfarms 1 with combine manifold like yours 1with 7810, and 1 with 7920. And all 3 engines run within 20hp of each other with the same turbo. The combine manifold is the nicest because everything is out of the way to do maintenance.
