Re: Diesel UTV horsepower, Thoughts on Teir 4
I hear you. When on a job in Peru, we had to have all our engines tested (at quite an expense I may add and all of them were brand spanking new) and if we dropped a drop of oil off a dipstick when checking the oil, we had to do an Environmental Impact Assessment plus scoop up the sand where it may have fallen, containerize it etc. Yet local trucks could go down the road belching out blue smoke at the rate of about a gallon per mile with no problems.

Was told by my dealer that the Kubota RTV 1100 I have was limited to 25MPH because above that speed it is no longer classed as a SMV and different government safety rules kick in.

PLEASE, back to the ORIGINAL question......HOW can we get more power out of our Kubota Diesels? (I have the D-1100) It is fine on level ground but going up my hills it drops to 11MPH EMPTY with my 170 lb butt on board.

If your RTV has hydrostatic tranny in it, then they just can't go fast. If its a CVT, those do have the ability. Transmission wise anyway..

^^^ This!
I've got a 2016 Polaris Brutus. It's slower than molasses; but, I didn't buy it for racing. It'll haul something like 2k lbs (total cargo), and tow 2k lbs: not sure it can do both at the same time! Right tool for my jobs. Land is flat, but is pretty uneven (except my driveway): I wouldn't want to try going fast with ANY vehicle! The HST makes it easy for my wife to operate. I think that top-end is about 32mph, though mine's not adjusted properly such that it can achieve that speed (perhaps 25mph): and, really, I've run it flat out on the local road and I wouldn't want to be running any faster as it really feels bouncy.
Don't want to lose precious cargo (she's a big girl now and more often rides on the passenger seat; I have her on leash, tethered, and will hold on to her if things get dicey):

The Bobcat UTV is hydrostatic and is claimed to go 30.

If the engine's a direct injection then a turbo will help, otherwise (it's an IDI) and it'll be a lot of cost for very little gain: engine in mine's a Yanmar (24hp?) IDI; I know of someone who put a turbo on theirs and power increase was nowhere near cost justified- very little power gain. I'd advise caution about increased power to the HST. Freaking parts on these things are stupid expensive.

Adding a turbo to a DI or IDI will not by itself increase hp.
The fuel rate needs to be increased also.
I added a turbo to my Ford 1720 tractor which is IDI and turned up the fuel and engine rpm I can say with no exaggeration that the HP increased perhaps 50%.
The performance & capabilities were vastly improved.
On my engine there are external adjustments for the fuel rate and max rpm.
Not sure where or how your kubota can be adjusted but some research should help you in your search for more HP.
