A hell of a ride boys! And if I was a betting man, I would bet somebody from the big "K" has been following along. Guys like you make me sit back in awe and shake my head,, ya done good! Now le see the bytch run !!!!!
Interesting thread for sure! Im always amazed at the skills others have and what they can do! I am a shadetree mechanic and can just do the basic maintenance on these tractors. So this thread brings me to the question...what is the advantage of having the turbo upgrade? The hydraulic pump regulates FEL lifting and BH digging force so the turbo is no help there or is it? Maybe some extra pulling power is my guess if your into dragging logs out of the woods? I just dont know what the advantage is with the turbo? So what are the fruits of your labor?^^^^
That's no spoiler to me, lol.
I had my Turbo system installed and operating for a least a month before I began posting my thread. I would just work on each chapter and then release it once I was finished. I enjoy writing but, it takes me quite some time to produce the content in my thread. It's been a fun journey and I really really have enjoyed the fruits of my labors. There's nothing like having that additional power supplied by Turbocharger.

LOL, thanks skeets. Stay tuned, there's more insanity to come!A hell of a ride boys! And if I was a betting man, I would bet somebody from the big "K" has been following along. Guys like you make me sit back in awe and shake my head,, ya done good! Now le see the bytch run !!!!!
The Turbo will not increase FEL lifting capacity or BH digging force.Interesting thread for sure! Im always amazed at the skills others have and what they can do!

Very nice. Congratulations on getting it completed, up and running. I appreciate you taking the time to share the trials, tribulations and successes of your project.Surprise! Me again. . .
Several weeks ago was the official startup and testing of the new turbocharger modification. At that time, the engine, turbo, and new pipework all performed nicely at all RPM's without the PTO (snow blower) engaged. However, when I engaged the PTO and rev'd up the engine RPM's to full throttle, I observed a fairly significant mechanical resonance that had me concerned. The new exhaust pipe assembly was vibrating back and forth in the middle at very high speed, which appeared as a blur. Changing the RPM tamed it down, but I didn't want the possibility of damage or a broken weld in the future, so I knew I had to do something.
Originally, I was going to run a long brace (~12") from the middle of the exhaust pipe across the engine compartment to a solid hard point. Today, I went down in the dungeon to work on the beast and discovered a better, simpler option. The exhaust pipe passed right over the belt/pulley adjustment bracket, which was hard-mounted to the engine block and had a conveniently located hole:

By utilizing a simple piece of steel bar, I was able to fabricate a bracket that would attach to the pulley bracket and a 2" clamp assembly. I attached the clamp end of the steel bar to the clamp with two pop rivets because of their thin heads, then drilled a hole on the other end to mount it to the pulley bracket:

Because of a weld right at the location where the clamp attaches, I had to offset everything off a bit to one side, but it did not affect performance and mounted up quite nicely:

I fired the beast back up and took it out into the driveway to check the new modification. Result? No significant resonance at full RPM (2500) or any other RPM with the PTO engaged!
These are the kind of things that can keep you up at night when running experimental equipment. Actually, I feel pretty lucky that it was a fairly simple problem that could be solved quickly and easily. It makes sense now: The new exhaust pipe assembly was attached originally on both ends, but not in the middle, leaving a resonant node that could vibrate at a certain mechanical speed (frequency). By making a simple bracket support the middle of the exhaust pipe, the resonance was damped out.
I am quite excited now to get the machine out in some real snow and start evaluating performance. My original goal was to recover the 24% loss of HP due to altitude, and maybe make a few extra pounds of pressure to boost performance. Guess it's a waiting game with the weather. Don't worry though, when I have some results, you guys will be the first to snow. . . errr. . . I mean, know!
