Re: Time to eco-mod the Caprice.
i bet a 6.3 chevy na diesel and a 6 speed trans could get 35 mpg or better in that car....
but an engine swap is a really huge deal. you would have to work hard to find one for cheap, but i'm sure they're out there.
a 6 speed in a car like that sounds like good fun
it's amazing to me how great of gas mileage the caprice and the crown vic are able to get even with 8 cylinder gasoline engines and automatic trans.
i'm not really convinced that less restrictive exhaust equates to more mpg. They did a story on NPR recently about fuel economy myths. one of them is that a new air filter will improve fuel economy. in a few different vehicles, they got mpg numbers using a k&n filter, a stock new filter, and an extremely dirty filter. In all three cases, the dirty filters gave the highest mpg numbers. Restrict the air flow, and the computer will automatically restrict the flow of fuel.
