Turbocharged Farmall H
"It'll make a 5th gear start up a grade with a 9-ft. Haybine on the back," says Joe Moore, Lambertville, N.J., who installed a turbocharger on his 1948 Farmall "Super H" with 8.5:1.0 pistons and a 157 CID "Super H" kit.
The turbocharger is a "blow-through" model made by Airesearch Mfg. Co., that pressurizes the carburetor rather than sucks air through the carburetor. "I did it this way to provide a back up system so the operator could continue operation of the tractor in the field if the turbo ever failed," says Moore, who says he uses the tractor 80% of the time on his horse farm.
"This tractor is vital because it's so efficient in the field. I run 4 pounds boost pressure at 1,800 rpm's full load. It weighs 5,000 lbs. without water in the tires and puts out 48 hp. at 1800 rpm's at 3 psi. I also use a Holly fuel pump with fuel boost at 3 to 6 psi. You must keep the inlet fuel pressure above the boost pressure of the turbocharger if you're using a blow-through system. If I were using a suck-through system with the carburetor ahead of the compressor inlet, then the fuel pressure could be reduced to 2 psi for 2 psi boost.
"The turbo gives a 40% boost in horsepower under load. I can tell because I also own another stock "H". The turbo H runs as smooth as glass at 190? water temperature under load.
"I pull a 9-ft. Haybine in 3rd or 4th gear and can also pull a New Holland 270 baler with a kicker and 17-ft. wagon with a 158-bale capacity."
Moore also installed a wide front end from a Farmall "M" for added stability. He converted the tractor for about $1,000.
