You’re about to live your life a quarter mile of grass at a time!

In all seriousness, that looks pretty nice. Any idea what the gains will be? How will you deal with engine management and tuning?

Really cool. Have you got to try it out much?

What did you set the waste gate at?

I removed one shim from the injection pump and maxed the injectors out. Running 10 psi boost. About to run a egt sensor to see the temp. Runs good. Not much faster on top end. Lots of torque now.

I'm around 10psi boost. It runs good. Sounds like a mini turbo Cummins. Top speed is not much faster. It has lots of torque now.

Because you don't want to over rev your engine, top speed should be about the same. But the time it takes to get there should be awesome!

you could probably crawl up a cliff if you could get traction.

Perhaps a dumb question, but is there something you could not do with your RTV before you upped the power?

I know with my BX tractor I spin the wheels well before running out of power. Upping the power would offer no benefit.

I get the MINE IS BIGGER THAN YOURS aspect...:thumbsup:

I go to rock crawling offroad parks. Wheeling up hill the kubota seems to bog factory. I also lifted it 2" and running 30" tires. It just needed that extra torque to climb. I won't have that problem now. Plus it sounds awesome too.
