Yup, I kinda figured there’s no one magic fuel setting for all tractors. The trick on mine is finding the fuel adjustment screw, as it is not in the same place as the 2501. That will be this year’s project before the snow flies again in fall.

Thanks Mike. I’ve come through a second winter with the turbo conversion on my B2650, and while it’s doing well, I think I’m leaving some horsepower on the table. This year I am planning to experiment with tuning. This is cool that your kits are starting to find there way into other machines...

This is way cool Mike. What size engine is in that machine? Is still using the same size turbo? Also, did he do any tuning? Solo

That is an amazing piece of artwork Mike! It sure makes a difference using smaller diameter pipe coming out of the turbo. Mine is functional but not pretty. Making that sharp u-turn is a biotch. Getting close to doing some tuning on my setup. Problem is, I don't have a good feel for where...

Ahh. . . I kinda figured you were on top of it. While I did run my B2650 this past winter with the new turbo with good success, I just felt there was more power to be had. I now realize the importance of tuning and adjustment. I now have the custom gauge display completed and will start tuning...

Hey Mike, I was browsing on YouTube the other night and came across these two videos of a guy tuning his L2501 for higher performance without a turbo. Don't know if you'd seen these or not, but they've got some great info. Check it out: Solo

Thanks Mike. I'll keep you posted. Solo

Ahhh. . . Got it. I'm really trying to wrap my head around the whole turbocharger performance thing. I don't understand the relationship between load and boost pressure yet. Like everybody else, I expected to set the throttle wide open and see at least 6-7 PSI boost, when in reality it only...

Hey Mike - quick question: Did your turbocharger require waste gate adjustments after you got it running? Does the preset tension out of the box actually open the gate at full throttle or before? Solo

Looks good Mike! Are you still selling a lot of kits? I made it through my first season with my turbo mod and had good luck with it. Might make some fuel adjustments next year to improve performance even more. I just about have my turbo instrument pod complete. I'll post some pictures when...

Just a quick update. . . Haven't had the kind of winter we had last year, when I was running the tractor every week or more. However, we have had several large storms dump some serious snow on us, and the tractor is handling it really well. I have made no fuel or timing adjustments, just the...

Hi Mike: Indeed, this simplifies the whole operation by not requiring any fussing with fuel adjustments. Kind of a "one and done" installation. When you think about it though, in a roundabout way the addition of a turbo for high altitude operation actually does change the fuel mixture of...

Success! Things have been pretty quiet on this thread lately because I've been waiting for the weather to provide good conditions for the initial turbocharger test. Well, this morning after 2 days of snow I got my chance. I was understandably nervous as I opened the garage door and stared...

Hi GrizBota: Glad you've been enjoying the build thread, it's taken years off my life. LOL. Those are two very good questions. I hope I can do them justice. . . 1) Using the 1.5” and 2.0” diameter pipe appears to have been driven based on available geometric space and routing location. Is...

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...

Thanks Mike: The tractor has been started up and run successfully with the turbocharger functioning well as far as I could tell. It was smooth and quiet through all RPM ranges without the PTO engaged, and EGT values looked good. There was one resonance I discovered on the exhaust pipe that I...

Now with the J-shaped header pipe attached on one side, and the 2" down pipe mounted on the other, we're almost there. This is the most nerve-wracking, brain-hacking, pucker-inducing part of the build. To be sure, there is no "one" way to complete this final part of the fabrication of the...

Ok, It's been a long difficult push, so lets get the exhaust pipe finished up and routed out of the engine compartment. In the last build post, the 1-1/2" J-shaped header pipe was clamped together and removed from the turbocharger to be tack welded. After completing this task, the header pipe...

Awesome news Mike! It's so cool to see a new product come to market and be so successful. I can only hope mine performs as well. Glad to hear you are going to redesign the front end of the exhaust pipe with a smaller diameter. It's so much easier with the 1-1/2" pipe, and the short spacer...

Alright, you guys ready for some pain? Here we go; the exhaust pipe fabrication. . . In my previous over-wordy post about steel, I outlined the pros and cons of stainless versus mild steel. Personally, I chose stainless steel for it's advantages and longevity, and just accepted it's cost...
