    Twins with Twins, Anyone?

    I've had a hard time keeping his expectations realistic. But he understands why you don't see any big HP diesel boats running 400ci. We started out at 800hp, and he was soon talking about 1200. Which I quickly explained is not an option, unless you plan to build 4 more for spares. I pegged...

    Twins with Twins, Anyone?

    Jeremy hasn't dropped the hammer and went to lunch yet.. I know that boat well, who you think gave them the idea? LOL. She's still long way from being wet. That owner expects 1200 all day long. While I know those engines made well over that for about 5 seconds, I'll be impressed when I see...

    Twins with Twins, Anyone?

    What you think about LML block, Callies, Howards, and Fingers rotating assemblies ,LMM heads, 12mm pump, and twin 64mm's side by side feeding them at 4000 R's. Goal is run DSP5 setups like I had on my boat, but with 600-1100 range settings. What ever they make, they gotta make it all day wide...

    Twins with Twins, Anyone?

    It won't be cheap that's for sure. Just the cranks, rods, and pistons equals more than I sold my whole LLY Dmax boat for.. But to have someone come to ya and say "build it right and do it up how you see fit" is a great honor. Only requirement, she be faster than it was with the BBC gassers...

    Twins with Twins, Anyone?

    Here is what got evicted. Nothing like tossing out a perfectly good pair of 900+ hp BBC's in exchange for a pair of smokey old diesels. Guess I'd better make her smoke pretty good then. :D

    Broken Crankshaft Count?

    I was speaking with Ivan at Fluid Damper, who has those tools mentioned in my post above. They are located just outside Buffalo NY a few miles. FD has an engine dyno setup with sensors to measure torsional twist at both ends using calibrated degree markings on a balancer and flywheel...

    Broken Crankshaft Count?

    Exact same thing my buddy Dave experienced on his failure at 7hrs in the boat. Had I even considered the crank, I would told him to check that first rather than chase what sounded like an electrical issue. Thus trashing the block by reving it up then letting it idle while we data logged. I had...

    VGT compounds

    What's interesting is those units from Nelson are small with divided housing. He's working on a housing with built in spool valves, which I had considered using on a previous build with big single. One could conceivably use the ECM turbo maps and VNT control power to operate the two spool...

    VGT compounds

    Not VNT's, but yesterday I put a call in to Nelson Racing Engines about their symmetrical turbos. For the twin engine setup I'm doing theses puppies are the bomb when it comes to good looks. While they specialize in gas setups, they've done a diesel with them too. Their suggestion for 1000hp...

    How To: LMM OS - MAP Scaling

    From what I've seen there is no good hardware reason you couldn't mod these ECM's to do what ever ya want. We attempted to load a LMM OS on a LBZ ECM using tech II one night for chitz and giggles. It started to take the firmware then crashed at like 20%... We were amazed that it even started...

    How To: LMM OS - MAP Scaling

    Yeah couple reasons, first and foremost I like the LMM OS better, plus way more of those ECM's are out there. Is the trucks I had available here to test on first. Also that GMLAN high speed canbus ArbID's we were sorting out together are actually different between LBZ and LMM. I caught that...

    How To: LMM OS - MAP Scaling

    By default the max table limits in the LMM OS set by EFIlive are 400kpa. I attempted to override these before and after changing the map scaling, but it knocked my changes back down to 400kpa. If the stock sensor is actually 3.5 BAR as I've read, then it would only read 350kpa or 50psi out of...

    How To: LMM OS - MAP Scaling

    For anyone looking to improve resolution in MAP related tables, or increase the output range of boost reading on displays. The long version of this discussion: http://www.duramaxdiesels.com/forum/showthread.php?t=70615 Default LMM OS MAP sensor scale reads 0-366 kPa or 0-53.1psi sensor input...

    Emergency Relearn on ECM works on LBZ

    Find a Tech 2 and reload a factory OS. It's not hard bricked, but EFI won't fix it at this point.

    Broken Crankshaft Count?

    Don't know how far anyone actually dove into measuring RPM based harmonics and crankshaft torsional vibrations on the AF cam research, but I had a nice chat yesterday with someone who has the right tools to measure such values. They can measure deflection and rebound along a crankshaft as each...

    Broken Crankshaft Count?

    I found the same comments when reading up on both units. The frequency range coverage on the fluidamper is stated to be much wider due to its silicon gel design. http://www.fluidampr.com/what/how-does-a-fluidampr-damper-work-55/ Reason I bring this up, Dave mentioned yesterday that while he...

    Broken Crankshaft Count?

    Here is an off the wall question that's maybe been brought up before. What about a internally balanced crank and a new style fluidamper? I know ATI is the go to setup because of the external counter weight issue, but lets reverse this for a second and say we ditch the weights then use the FD...

    Broken Crankshaft Count?

    Thanks Dave. Believe he spoke with Jeremy today. Winberg is who gave us that 16 week timeframe. We also hit up Guy for options. I even checked with Crower, best prices, but 10-12 weeks on their made to order 4340CM stock or big journal setup. Obviously people are buying them up quicker than...

    Broken Crankshaft Count?

    As of 10 minutes ago, there is 16 week wait on the stock journal billet cranks from the manufacture. Seems someone in Indiana bought up all the inventory. Who has one on the bench I can buy before dinner time?
