Tune Up, Slow Down, And Unload To Squeeze Extra Miles Per Gallon Of Gasoline ...

Properly inflated tires improve gas mileage by up to 3.3 percent. Underinflated tires can lower fuel economy by 0.3 percent for every one pound-per-square-inch drop in the pressure of all four tires. Do not rely solely on the tire pressure−monitoring system to detect an underinflated tire—it’s best to check tires with a good gauge once a month and check your owner’s manual for more information.

Tune Up, Slow Down, And Unload To Squeeze Extra Miles Per Gallon Of Gasoline ...

Loose or poorly fitting gas caps not only can trigger the “check engine” light, they send 147 million gallons of gasoline into the air as vapor every year, according to the Discovery Channel. A missing or poorly fitting cap can reduce fuel economy by 1




What Ever Happened To Smokey's Hot-Vapor Engine?

Every year we get reader mes-sages asking about the fate of a potential breakthrough engine technology developed by late legendary racing engine builder and high-perf tuner Henry “Smokey” Yunick with his longtime collaborator Ralph Johnson.

Every year we get reader mes-sages asking about the fate of a potential breakthrough engine technology developed by late legendary racing engine builder and high-perf tuner Henry “Smokey” Yunick with his longtime collaborator Ralph Johnson. HOT ROD first reported on this adiabatic, “hot vapor” (or “hot air”) engine in the June ’84 issue. “The Next Step” by C.J. Baker fully explained how Smokey developed a 2.5L (151ci) Iron Duke four-cylinder Fiero engine that met all ’80s emissions standards (with a carburetor and no computer), made 250 hp and 250 lb-ft of torque (compared with about 90 hp and 125 lb-ft stock), went 0 to 60 mph in 6.5 seconds (stock was 12 to 13 seconds), and managed to get as high as 51 mpg on the highway running 93-octane pump unleaded premium gas (the stocker got about 35 mpg on 87-octane). The hot-vapor engine did all this running unheard of high temperatures at an extremely lean air/fuel ratio, in seeming violation of accepted internal-combustion-engine physics.
