Turbocharging a natural gas engine

[Jake Sternberg]

Compressed natural gas has an octane rating around 120 +

turbocharging an engine using natural gas makes sense
because natural gas costs about 35-40 cents per "gallon"
in your home and about 65 cents per "gallon" at a gas station
(if you don't have a 3600 PSI pump at your house).

many cities in the US offer a rebate to convert your vehicle
to natural gas, like Austin, texas.  here, i can convert for
free.

(* a "gallon" of compressed natural gas is the amount of CNG with
the equivalent energy of a gallon of gasoline)
