    Twins with Twins, Anyone?

    Shouldn't ever needed to mess with it my point. Not the money either. But when I pay for top shelf products, and go the extra mile to provide feedback, by having them regularly serviced by that manufacturer, I expect a certain level of attention be given in return. And a straight answer...

    Twins with Twins, Anyone?

    If anyone noticed, I cut the Vibrant clamp end off the compressor housing before I even tried to loosen the bell. Why you might ask would you do that since that cover fits the same turbo and engine as is?? Two reasons. 1st. They have greatly modified the newer compressor housings since my...

    Have 2 turbo back, along with the old compressor housings. Seems they only polish the pieces under the air filters now. But not the side you can actually see under a glass hatch. No biggie, I have a guy locally who's good. Once done testing I'll pop the covers off, weld the bells in place, and...

    At current $$$ per hours run time, those NLX units be approaching a cost of operation threshold which lead to changing out that last set of surface drives. Figured it up, counting the original NRE's, we are currently at 19k into turbos, with about 60hrs on each engines. That's $158.00 per hour...

    Some updates on the turbos. Nothing conclusive for a cause of failure besides it went out of balance, and then ingested itself. After I brought it up, surge became the most likely cause. But no evidence presented to say one way or another. Options / suggestions were upsize the turbine wheels to...

    Turbos I would really love to try is a pair of these.. Regin feature would do great at limiting overspeed, while also recharging the batteries. Keep watching this technology, F1 been using it for years now. https://www.garrettmotion.com/electric-hybrid/garrett-e-turbo/

    After a nice follow up call with the Bullseye, overspeed likely wasn't an issue. Nothing conclusive yet, but they feel it wasn't spinning more than 80k rpm or so under the part throttle free rev conditions. Also the wheel likely didn't let go because of the noted surge related stress. That...

    Heck, I haven't even set rev limiters on fueling yet. If I set that around 4800, might help keep the wheel speed down. But at this point we don't have a clue where it's spinning. Sent from my SM-G892A using Tapatalk

    That's certainly a good starting point size wise. The original Dmax boat sported a water cooled GT4094R, which while is known to be slightly over rated on it's power potential, suffered zero issues over the 300hrs I beat on it. The 550hp jet boat engine also sports that same Garrett unit today...

    08 H2/LMM harness help needed

    Here ya go. This should help.. I typically tie all the pink wires together, along with the blue wire listed as Wakeup Serial Data. The single red wire goes to battery. That will get ya up and running. However the MAF pink should be kept separate as shown below, so a bad MAF doesn't leave ya...

    Twins with Twins, Anyone?

    Well I'm losing faith in Bullseye Power pretty quickly. Received the inspection report from one of their techs today which stated that the turbo ingested something, and that's what caused the compressor wheel to explode. Also stated that the bell / map ring was misaligned, and that was causing...

    What was I just saying? Stbd exhaust housing looking a bit oily. Wasn't that way 20hrs ago... Port spewed some into the intake side due to tweaked shaft angle, but exhaust was dry. Ah the fun of having twins.. Sent from my SM-G892A using Tapatalk

    Well now I'm back to chicken or egg questions. Seems shaft is bent, not broken. Velocity stack is tweaked pretty good, and I couldn't budge it with a strap wrench couple months back. Maybe she touched the wheel first, then things went south.. either way, they are both off and headed in fir a...

    Actually the one I just replaced only needs a lower shaft bearing. Replace that and will now have a completely new/rebuilt spare. Still have the new in box lower half from last year. And good thing because the one on port engine has required a "hammer assisted start" at least twice in past...

    Exactly the same unit.. Is why I am so disappointed in these now. Bet the one I purchased back in 2010 is still good to go on the old boat. Sent from my SM-G892A using Tapatalk

    One more to add to the aftermarket fail list for the week. Since the early days of my first PPE boat I've been a fan of the SX / Edelbrock EDL-1792 160gph fuel pumps. Primary reason is it's internal bypass regulator that doesn't require an additional return line. Edelbrock has tagged them "Not...

    Twins with Twins, Anyone?

    Yes it is. And will let ya know tomorrow.. I doubt it was a single spike that caused it. But when one prop breaks loose, sometimes gotta wait a few seconds for the other engine to break loose before shifting. So if an overspeed failure, then be hard to prevent. One of my diesel buddies did...
