I see ebay is offering a blower kit for a WD45. Anybody have any experience or thoughts on this? Horsepower increase? Would the engine and drive train handle the increase in power? |

| I don't know the url, but go to ebay, type in wd45, put them in order by price and it is at the $1500 mark. |

Never tried one, but you have to remember that engine was NEVER intended to have a blower forcing much more airand fuel into the combustion chambers. The 226 only has 3 main bearings - could break the crank (at least). I am sure the transmission could handle it. The engine might for a while, depending what you were doing with it. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

In the 1970's-80's Dennis Lucas from Indiana pulled a turboed WD Allis nationally in the 5000 class and did pretty good..I'm sure that he broke some stuff doing it..About 40 plus years ago the Bentlage family in southwest MO pulled a turboed WD-45 AC that did pretty good as a state 4500 class puller..The tractor is sitting in a shed...There is currently another turboed WD-45 pulling in southwest Missouri...I'm sure that Mack pulled one in the good ole days..Those 226's are some tough little engines if built right.. |

I'm guessing its a Keystone kit. Haven't heard much good or bad about it. Like any other horsepower add on, it's how you use it that determines what breaks first. AaronSEIA

Seen reports both ways on them but Id guess the reason for opinions would be the various expectations and capabilities of the buyers. Have seen the kit in person and did not see any issues with the actual parts. I would expect that at stock compression ratios that only a very small amount of boost would require at least 91 grade fuel, maybe better and some ignition timing adjustment. A real good candidate would be a tractor with kerosene pistons, then you could throw some PSI at it and see a real HP change  Drive train ultimate strength and working life is two entirely different things that is often talked about as one subject. Is 100HP going to break a 4500lb WD45 the first time a load is applied? Obviously not as it's been done many times over the years. That doesn't mean you can build a 100HP WD45 throw a 5-16 plow behind it every spring and expect your grandsons to inherit it with an intact drive train

You couldn't put all the power to the ground unless you added some weight. If you left the tractor with only one wheel weight on each side and fluid in the tires, loss of traction might save the drive train. If you weighted the tractor down, who knows what would break first… |

| If you've got $1500 to throw at a WD-45 gas tractor, I'd just overhaul the engine and install D-17 or 170 pistons and sleeves. |
