    Twins with Twins, Anyone?

    Got her back safely on 4 wheels, oil cooler and filter housing mounted , and the 12AN lines cut to fit. Now to tear everthing off again, clean out lines, tighter the male fittings, hopefully remember to remove plugs behind the block adapter, fill it with oil and see if she makes pressure...

    Twins with Twins, Anyone?

    I'm scared too... Actually it's been setting on 2 half inch bolts and a block of wood for past week. See pix. Been afraid to even breathe on it.. lol. Had to modify those mounting plates, and how the cart wheels bolt up to clear this new stuff. Just got wheels back yesterday, now I can roll...

    Got the oil cooler fittings figured out. A 45 into a 90 lines up perfect with the filter housing, but causes tight fit on a water pump exit.. But for today, it's good enough to get the oil flowing to fire this one up.. Sent from my SAMSUNG-SM-G870A using Tapatalk

    Good math, just change that seawater pipe to 1.5" dia at 90gpm :-) And the coolers are double pass so the actual diameter of the copper contact area will be like 3" total or about. It's actually like 80 x 1/8"dia tubes inside. I've seen this same charge cooler core used on other 750hp marine...

    Twins with Twins, Anyone?

    Somewhere I have the details. Lenco drew em up based off of hp and cubic inches comparable to a 1200hp BBC. He wanted to do 5" x 27" .. but we only have 24" between the plates and mounts. So we recalculated to 6" dia and shorter length. This seawater side is 2 stages out at 1.5" min thru the...

    Twins with Twins, Anyone?

    Way more than my brain wanted.. The Merc racing seawater pump is rated at over 200 gpm. 3 x 1" impeller pumps stacked. However true bench test numbers on a single 1" pump are they top out around 45gpm. So, that's why I call this 2 stage run at 90. My 700hp boat had a single 1" merc pump for...

    6" dia x 22" long. Cupronickle cores, 1.75 in and outs on engine side, circulated by a 55gpm electric. Two stages of that Merc 1200 race pump are pushing 90+gpm seawater to it and the charger cooler. With that setup, the manufacture estimated I'll still need at least a 2 gallon reservoir...

    Before swapping the end plates, I did a quick mock up with heat exchanger in position. As ya can see, it starts getting a bit tight on port placement really quick. Sent from my SAMSUNG-SM-G870A using Tapatalk

    On this one I can spin it out a good bit if needed. Hitting the oil filter ports correctly is only requirement. But, on the other engine, the main heat exchanger and electric waterpump have to mount under the oil cooler.. So using this engine to gauge it. There is also a 1.25" cooling line...

    Thanks for the encouragement. I'm trying to get these twin Duramax engines on the water before Industrial rebuilds my buddies twin 1000hp Cummins boat setup for the 3rd time.. I call this the REAL UCC... Build a 900+hp diesel engine with under 7L displacement, drop it in a boat, and make it...

    Eenie meenie miney moe, how in the hell should this oil cooler go?? Where the oil filter base is gonna mount in rear plate, two of those lines will only have 2" hose between the AN fittings.. The red caps are for fuel return lines, which I can snake much easier than 12 AN hoses.... Sent from...

    See if you can locate one of these adapters for the dyno.. It's probably called a twin disk, zf, or borg warner 72c adapter. That one is on a buddies old super flow marine setup over in NYC. I'm thinking maybe bring one engine over for ucc, then you can take it home with ya... Sent from my...

    LML Marine swap

    I still haven't figured out why it wouldn't fire on the original DSP5 tune.. Found a couple more wires in the lbz chassis harness side that are different from an lmm, but nothing critical. We ran a lmm ecm on Marks dyno with lbz harness and only MAF was missing. I swapped those on this harness...

    Gale Banks Likes the LP5

    JJ texted me last week about getting together to go over a new design. Mahle has bailed on production, as expected. Was obviously just blowing smoke at PRI 2016. So screw em, time to move on. Now if I could get GB to commit to a few minutes on the phone, we might have something worth testing...

    Thanks Gale for confirming what I've been preaching for years on piston oiling and cooling.. :thumb: Think I found where those others 2 sets of Mahle Monotherms went too... :roflmao:

    I live south of Athens about 25 miles. Right smack in the middle of nowhere. My front yard is the Ohio River. :spit:

    Other priorities I guess. Little more rigging related work between the crankshafts and props to handle that power level than expected.. I like the Mastercraft idea. No driveline changes required... Well, till it twists the prop shaft off... Sent from my SAMSUNG-SM-G870A using Tapatalk
