    Twins with Twins, Anyone?

    From speaking with Curtis Halvorson about this several times, you likely won't need to worry about it at planned power levels. Issue arises from boiling coolant inside the heads at higher power levels. Curtis had issues with melting the heads down due to trapped air pockets on his salt flats...

    Received the raw upper valve covers from water jet today. Believe I can work with these thick chunks. Also received "16" injectors and some return line kits today from Andrew. Brand new Bosch sticks with 80% over tips. He bench tested them and then indexed the heads for me so all wires run in...

    Thanks. Billet upper covers should be here this week. I cut them out of 1/2" so we can do some old school looking Fenton styling to them. As for protrusion, there wasn't enough to make it worth measuring. Could have ran A gaskets without any issues. We were originally going with Empire cams...

    Few pics of the intake and fuel rails mocked up.

    Broken Crankshaft Count?

    This Callies you mean :D If someones broke one, they must have dropped it on the concrete unloading it... Mine haven't spun under their own power yet. The narrow journal approach and larger filet is being used by several manufactures I spoke with while exploring options. Stock and stroker...

    LML Marine swap

    That's kinda what I was thinking for lowers. Cerakote makes a high gloss clear that ya bake on I found. https://www.clearcoating.com/products/H-300/ Know that's a popular coating with guns these days.. These lowers were originally "hard anodized" but have scratches in them now and need some...

    Hurry up Hawk, I need to squeeze something into that shop... :spit: Those engines look great. I'm done with measuring and mock up, now trying to get Will to take on some of the bilge work for me. So will be rolling down there soon as your ready to hit the water. What's the name of the primer...

    Some pics of the first short block assembled. One little mod we did on these blocks was replacing the press in oil passage plugs with threaded brass plugs. The front plug needed a little custom grove cut to insure full oil flow to that main port. We also reverted back to a one piece cam gear...

    When I had the first Duramax boat my buddy bought a 19' flats boat with 300 V-Max. I could run away from him for short distances, then I'd have to get out of the throttle. Where he could run 70mph wide open all day, till the tank ran dry... That's where the outboard have it over inboards.

    Livorsi has been building a throttle / shifter combo with GM TPS setup for Sweden Marine Diesel a year or two now. Plug and Play to the ECM. On the NMEA gauge outputs, that one's all my work.. :thumb: http://www.duramaxdiesels.com/forum/showthread.php?t=68389 Ben is doing a cool dual...

    Picture of the drives, and what I pulled them off of... 50' Nor-Tech with two 1800hp turbines. This is just an old Baja, in a market where a new hull cost more than this boat will be finished.

    CMI.. Same corp umbrella as Livorsi now. Who's also doing the Dmax electronic throttles and all the N2k gauges for this build. And your right about the jack spent on performance boats.. Example, a twin turbo 1100hp QC4v Mercury Racing engine is over 120k without the out drive. Looking at 170k...

    Not polished yet either... :D Actually a better deal than I was originally told by the guy who had that set on the Wagler engine displayed at PRI. Those cost me exactly same as the custom set I built in house a few months back, minus up pipes. I have to build the up pipes in house with T4...

    More shiny parts. These you'll see at least.

    Twins with Twins, Anyone?

    Before sending it out to powder coating, I did a quick mock up with one of the Banks intake to get some measurements. While certainly not for everyone due to it's 80gpm water requirement, I do really like the design and time someone spent laying out these molds. Rather than color coat the whole...

    Times got pushed a couple weeks due to cranks. But we still plan on having them together in 2 weeks. All the long block pieces for one are ready, only missing a medium duty oil pan an rear cover for the second engine if anyone has those taking up space. My Mr Goodwrech partner / engine builder...

    Came home tonight to find a couple tubes marked FRAGILE left at the door. That's the last of the rotating pieces since second crank arrived yesterday. Securing a pair of AF cams on short notice proved to be about as hard has buying 2 billet cranks. Gonna give Jeremy's stage one's a try. He...

    The rod clearance came in right where we wanted. Which I'm still amazed how we accomplished that without first having the cranks. Lastly, block was decked 005, piston cut 010, and they still managed to stick out 001... Rings are cut, clearance testing is done, head are off to the machine...

    88.4lbs is what the scale says an internal balanced billet crank weights in at.. Add 8 shiny 5lb piston and rod combo's brings us up to 128lbs of rotating mass, not counting flywheel and harmonic balancer. I know the flywheels will be right at 75lbs, so with the balancer lets round it all up...

    Finally, first one hot off the lathe... 100+lbs of polished 4330 and tungsten. I sure hope it was worth the wait. http://www.callies.com/crankshafts/ultra-billet-crankshafts/ultra-billet-duramax/
