    Twins with Twins, Anyone?

    Well today was interesting, or a typical by boating standards. Thursday we logged about 38 miles on the bay, and besides running aground once, great day. However when we parked the boat, noted some fuel in the bilge running out from under the port engine intake. Figured was just a return line...

    What I love most about a Duramax, seeing tach recalls like these every night.. They will pull hard into the 5's in low gear if ya let em eat. Sent from my SM-G892A using Tapatalk

    Ah yeah had to take this pic for the youtube guy who attempted to drive his duramax truck out the pass a few weeks back. Ah, this way works much better. But if he wants to try again, I'll happily tow him out the pass... Sent from my SM-G892A using Tapatalk

    Tested my temp safety settings in the tunes today. Ran aground pulling outa the channel where I'm hanging out and testing. Didn't think much about it until got up on plane and stbd engine defueled. Check fuel pressure, turbo, but she wouldn't make any boost. Then noticed the sea strainer full...

    Twins with Twins, Anyone?

    Fix some stupid stuff been troubling me for a while, then she's done. But also gotta find some props that hook better [less slip] so that 81 turns into 101mph at 4k. Then turn it up, cause we are currently only making about 780hp tops based on EGT. I could have easily ran up to 90 and 5k rpm...

    Here is some roost video from a short blast today. Gotta get some cameras and mics on here, the gopro knock offs suck for sound.. Source: https://youtu.be/Cvui1Nvhgxw

    Logged a few more miles today, and put some heat in em for few minutes. Topped her out at 81mph around 4k. But according to egt, she's not straining to hard up there with these props. Sent from my SM-G892A using Tapatalk

    Actually the RPM # was in low gear, while speed was in high gear.. Hard to think about it that way since it's a 2spd boat. I've yet to log the slip numbers on these props, maybe next week.

    Made it back out on the water Wed for a quick run with another forum member, who generously loaned me some decent props to test with. Changed that line, and once things checked out, jumped on it for a short run. Hope to be back out again tomorrow.

    Comes off the ppe block adapter plate by 6AN, then reduces to 4AN up by ECM.. Remnance of the twin setup plumbing. No access to the LML top hole due to the intake. Sent from my SM-G892A using Tapatalk

    Got some new turbo lines that shouldn't be so heat sensitive.. Found a local shop that does top notch hose work, faster and cheaper than I can do myself. Note to self. No pretty Vibrant rubber hose around hot parts. :-) Sent from my SM-G892A using Tapatalk

    Got it up to 70mph again that day. Next day out discovered an oil feed line on turbo end leaking. Fixed that but didn't notice the oil soaked turbo cover. Next time we got up to 70, she developed a warm glow under the glass. Upgrading both turbo feed lines now.. lol Sent from my SM-G892A...

    LMM lift pump?? DSP 5??

    From my research that is for transfer pump activation. I have yet to figure out how to activate it without a scan tool. But thanks for bringing it up again because I will do some digging in the bin files for it. Sent from my SM-G892A using Tapatalk

    ECT readings vs. gauge temp readings after tune

    Thanks for that info I'll check for pinout diff on a 10. I've verifved the ECM only ever uses one for calculations, but both can be read with a scan tool. Reason I guess that was his issue. My GM buddy told me the reason for second sensor, but it's been so long ago I forgot their reasoning ..

    ECT readings vs. gauge temp readings after tune

    Not sure on the LML, but the LMM has two ECT sensors in the thermostat hosing. If same, I'd suggest unplugging them one at a time to identify which values are linked to each reading. Possible the scan tool is reading one sensor, while dash is reading the other. Best guess off top of my head, is...

    That's how old man Kennedy made all their money. Then used it to put his kids in positions of power in our gov. Maybe a few well known tunners should run for Congress and represent their customers. Sent from my SM-G892A using Tapatalk
