Any chance you could play with the fuel on the 1025r NA motors and see if there is anything left on the table? I'd be curious if you could pick up a few hp. Maybe even play with the timing and fuel and see what can be had?
You can likely get a few HP from just turning up the fuel, but most of it will go out the pipe as black smoke. I find that, at least at sea level, the 1025R will still smoke pretty good under load, so significant change in HP by adding more fuel alone. I haven't tested it, but might in the future. Timing would also help, but you would want to watch exhaust temps and given the RPMs we're running are relatively low, I don't expect a huge gain there. In race applications where you pushing 6k, then you'll see more influence from timing, but I don't think these engines significantly retarded timing...but it's likely a little conservative to keep the combustion temps lower. I think they control power and emissions mostly with fuel and keep the timing about right for the fuel and RPMs. This last part is opinion based on anecdotal tests...nothing scientific where I captured the appropriate data.
HP is NOT measured as you know, its Calculated from TORQUE as you started to say, and involves Variables. Love your videos, AND your products!
Very interesting and pretty thorough. I appreciate your time. Thank You!

Are they the same engine? I thought the 3039r engine was slightly different than the 2038r…
Any updates on the 3025 turbo?
I"m trying to get to it before I leave on vacation, but I'll have an update in early Aug for sure.
I just got a used 3039r with 275a backhoe, and found your website. Do any of your products provide improvement for my equipment?
I will have products for the 3R tractors soon. Thanks!
Cool stuff.
Did you know 1 horse can have about 15 horsepower? It's a weird unit of measurement. 😆😆
FYI - My 2038R tops out at 2650 engine rpm and 570 PTO rpm
This is good to know. Thanks!
