NHC 250 Turbo Conversion in M923
Yes, it's best to have a flex section but it's very difficult to find the room to add it in. FYI, the compressor tubing on my bht3b turbo is 3.5"- US6x4

Doesn't he like to add .120" spacers to run rpms in the danger zone? His engines probably don't last very long.- US6x4

NHC 250 Turbo Conversion in M923
It's loud for sure and I love it; 1000-1600 rpm sounds like a jet spooling up for take off when the turbo whine is louder than the exhaust note. The jakes sound super sexy though. They let out a sharp, staccato hammering at high rims and a mellow burble under 1700 or so. A long drive for me...- US6x4

NHC 250 Turbo Conversion in M923
The truck in the second video is mine and for the sake of compiling numbers it's running a #17 button and the most I've seen is 14+ psi & 900° F. I don't know what rail pressures it's running at but the new button has caused new fuel leaks around the manual shutoff valve...- US6x4
