Hi definatly take the fan off you might be surprised how much power you gain. I ran Detriot 60 series engine tandem grain trucks for a guy about 400 hp I think, when running at 4 mile an hour down the side of the combine if the fan kicked in it would drop the truck back a few mph. Then go back up when it kicked out so power was going some where!. I put a 510 perkins in a pull tractor took the fan off and fitted electric, freed the motor 300 rpms and had to shut revs back for tech . I never used a thermostat switch just my eye on the gauge and flicked the switch if needed after a pull. I would recommend fitting a thermo switch to guard against operator error. Maybe set it so the tractor runs a little hot to help keep bores from glazing and the motor will probably work better for it. Most motors like hard work and getting warmed up good from my experience. Alternators fans and water pumps all sap power. A guy in the u.k that pulled a ford major took it all off and used electric instead of mechanical , then just re charged the battery in the pits with a generator and booster after the run.
