Thanks for all the input. These are are liquid cooled manifolds and up pipes. The picture doesn't show the jackets. We still need to fabricate a custom water injected down pipe. We will need some help with the muffler set up though? Not sure if the gas muffler is to restrictive for our boosted diesel.
Anyone have some contact info for a good V drive shop? |

very interesting project - you noted that the diesel will be left stock without turbos, but in on road vehicle applications i thought the LMM had a single turbo.
The kodiak LMM looks to be rated at 620lbs of torque, which certainly isn't double what the big block put out, shoot my MCX is rated at 365 lbs. The most important choice will be the prop and transmission gearing... since the LMM hits its max torque around 1,600 rpms i'd have to imagine a HUGE prop or a geared up transmission, with the red line at 3,250 rpms you'll need to have a plan for the top end too |

We will be running the LMM's factory single turbo with a possible twin turbo set up in the future. Our X80's V drive should be able to handle 450 ft lbs, however a different ratio will be needed to optimize the lower RPM. With a stock block and heads the Duramax motor is capable of producing around 650hp or 1200+ ftlbs with proper tunning and turbo's. This motor will not be tuned for max HP just max efficiency. |

A fellow member installed a diesel into his 190 (smaller boat) but there may be some tips in this thread. Worth reading. I think he was in Turkey so that made it even more interesting.....

Alright, just looked at your pictures closer and saw a few things that answered some questions. I was thinking you manifolds were exhausting the water but just internal circulation. Thats good but still think you going to run into heat problems with the up pipes unless you can find a cooling system for them as well. Then you have to have an intercooler setup. That will take up room and have zero air circulation unless you can find a heat exchanging coil setup. that will take more plumning etc.
I see the EGR is off and i'd leave that off and bypass... POS in my opinion. I'm very intrested in the project. Please keep us posted. I'm very familiar with the LMM and always looking at ways to improve performance. |
