Thank you. For an update - For the past couple years I have been on-again, off-again with work on my M1028 due to health issues. My health has now much improved and I was almost ready to install the new P400 / 700R4 / NP241 drivetrain, but then I kinda got the hots for a supercharger. It seems there are only 2 options for a 6.5 diesel, either the Rotrex which SWFB is currently installing or the Bullet from Australia. I have been back-and-forth with Bullet via email, and am quite comfortable with their design and performance projections, however I am purposefully delaying any decision until I see how SWFB's installation with the Rotrex turns out. There are pro's and con's to each system, so I will just need to wait and see. One big advantage for the Bullet supercharger is the built-in water-to-air intercooler which fits in the custom aluminum manifold directly under the blower. Because of this design feature, I am currently leaning towards the Bullet. Stay tuned.............Spectacular build! Hope you're doing well!
