This reminds me of a customer I had brought in his 3010. He had bought an M&W turbocharger kit and wanted it installed. He complained the tractor had no power. I said fine, as long as he understood the potential problems. Before we started any work, I put it on the dyno to check power. It was only producing 38 hp. Spec was 59 I believe. I replaced fuel and air filters and gained 10 hp. I then determined injection pump and injectors were worn out. We sent out the pump and had them bump up fuel delivery 15% per instructions in M&W kit. I installed all 4 new injectors and ran on dyno again. Power was then at 65 hp. I called customer to see if he still wanted turbo installed since the power was now almost double what it was when he brought it in. He said yes(he already had a 4020 with M&W kit and loved it.) Installed turbo kit which included a pyrometer. Final power output was 91hp. That was over 20 years ago and that tractor is still running strong with no problems. The customer is very conscientious aboout watching exhaust temperature and he backs off the load if temps get too high. I just thought I would share this story to show that power can be set up without disaster, but operator of machine needs to understand limitations. On non turbo engines, it is difficult to get large gains in power due to not enough air is available to burn extra fuel. The main thing to consider is be sure proper maintenance is done to ensure the engine is performing up to it's potential before doing any mods. You might find modification is not necassary.
