Test Results
HP Firing Pressure (psi) Exhaust Temp (F)
Baseline 266 @3400 1711 1156
With FFC 268 @3400 1740 1151

Fuel Consumption declined from 19.1 gal / hour to 17.4 gal / hour post Fitch installation

Summary: The engine picked up 2 HP, increased fuel efficiency by 1.7 gallons per hour. Exhaust temperature was 5 degrees cooler. Firing Pressure rose 29 PSI. Firing pressures are a result of fuel and air mixtures and the percentages of the fuel burnt. The more complete the burn in the combustion chamber, the higher the firing pressures will be. Results of this test indicate fuel economy increased 10% without any loss of power.
