Hey Steve, we greatly appreciate the accolades and feedback on the Turbo Kit and your tractor's newfound performance! Thank you! We're thrilled that the Turbo Kit has met (perhaps exceeded) your expectations! Thanks again for your post and we're very happy we are able to bring this product to you and other tractor owners!

Question. Did you increase the fuel settings on your L2501, or are you running on the factory Kubota settings?

Mike
I did not touch the fuel settings or anything else. Installed it and ran it. I did install a pyrometer yesterday and ran it briefly and EGT's completely normal for what I was doing.

That's what I thought!
Fantastic!

Most of our customers can't keep themselves from messing with the fuel settings, lol.
The temptation sometimes is just too great! :LOL:

I really love the fact that your are running the Turbo Kit as pure altitude compensation on the factory fuel settings!

According to google AI it should restore the 20% lost to elevation and give an additional couple HP on top of that, assuming a 4.5 psi boost. Yes all I wanted was to restore the lost power and it is VERY noticeable.

Excellent. That’s great to hear!

How was your smoke output before the Turbo Kit? And, how is it now, with the Turbo Kit installed for comparison?

It had a puff at start up before, and still does. I never noticed a lot of smoke before or after the turbo but the tractor hasn't seen any heavy loads yet. I'll let you know when it does. I failed to mention I have only run this tractor for 8 hours or so that's why I'm not sure about the smoke. Haven't done any real heavy stuff.

^^^^
Lots of our high elevation customers report lots of smoke during heavy operation prior to the Turbo Kit installation and no smoke, or very little smoke afterwards.

Update. Did some mowing with 5' rotary mower through wet, but not all that thick grass and weeds up and down a 100 yard long slight incline and EGT never above 600 degrees. Good to see that! As far as I can tell I'm not going to see a lot of smoke until snow blowing or pulling a full box blade.

Great to hear!

We look forward to hearing about the performance pulling a full box blade and your snow blowing adventures!

Tractor Turbo Kit installation season has begun. Right now shipping ETA is one week on L2501 Turbo Kits. Shipping times will increase as we push towards winter. If you’re planning on a Turbo Kit before spring, now is a great time to order!

We’re working on getting the L3240 Turbo Kits back in stock and the LX2610/LX2620 Turbo Kits will get going this upcoming spring. The L2502 Turbo Kit we expect will be around the same time frame (assuming we get a donor tractor). Good things are coming!
