Dyno tune

EFR2441 · Jan 8, 2006

Does anyone know of a NH dealer or diesel mechanic in the northeast with a dyno? My father has a Ford 1320 that he would like to 'bump up' slightly (with a mid-mount mower and hydro transmission, it doesn't have enough power to mow with). I am aware of warranty issues and EGT's, and we are both well aware that a bigger tractor with more HP would be better, but that is easier said than done on a retiree's income.

Thanks, Erik

About the only thing you can really do safely is turn up the fuel pressure slightly. You have to remember the rest of the parts are built for the HP it came with(trans,rear end,axles).Also as you increase the HP you shorten the life span and increase fuel consumption. If you were lucky enough to get a 10% increase that would only be 2hp. you probably wouldn't notice the difference.

Any reasonably equipped dealer will have a PTO dyno. Start calling local dealers and ask them yourself. Make sure they have the talent as well as the dyno. A 1320 can be tweaked a little. Trust me you will notice a 2HP gain on that tractor. Nothing to lose, especially if it is a little under spec to begin with which can and does happen. To the other guy; it has nothing to do with fuel pressure, it's volume, baby!

When you are mowing fast (not driving fast /forums/images/graemlins/laugh.gif) at least 1 time a week.
I don't know what you are doing now.

I had the same problem with my TC24DA and 60" RFM. It seemed like I had more power with my old 17hp Kubota. Anyways I bumped up the injection pump a quarter turn on the max fuel setting and I've noticed a decent amount of improvement. I think from the factory things are adjusted to the minimun effectiveness for emissions reasons? As for as emissions are concerned, I guess I'll just go throw some more coal in the furnace and keep warm!

Where is such a setting? I've always thought mine burned overly rich and used too much fuel.

Look under where the fuel lines exit the injection pump. There are two caps. One small plastic and one larger round cylindrical metal cap. The caps are on there because you are not supposed to mess with these as they are set to specs. (so they say) and it also an emissions isssue. The larger cap covers a screw and jamb-nut that regulates the maximum fuel amount injected. The smaller cap covers the same type of screw, and that adjusts the "engine-racing" or redline setting. I removed the larger metal cover and turned the max. fuel adj. counter-clockwise 1/4 turn. You really probably don't want to mess with this but I did anyway. I can now climb the driveway in high gear and also I've noticed more torque in the low-end in low range. If you do mess with it, don't over do it because more fuel = higher temps and you could have a melt down. Under full throttle and moderate/heavy load I do get I LITTLE black smoke. Before the adjustment I could almost lug the engine all the way down to stalling from full throttle (mowing, etc.) and get no smoke at all. Black smoke = unburned fuel and now I know it's getting enough. I'm sure that someone out there will have a different opinion about all of this. Good luck.
