Fuel Mileage booster’s

PT Cruisers had both a turbo and a non-turbo engine. Both were 2.4L , 4valve , DOHC engines. The turbo engine got worse mileage than the non-turbo engine. Partly due to less compression. [There is always tradeoffs].

An advantage of turbos is engine displacement. If you can make the same horsepower with half the cubic inches [and a turbo], then you cut your idle fuel consumption in half. And less engine weight. The old [1989] Dodge Cummins engine made 160 HP without a turbo. I think they are up around 400 HP now. How much would a 400 HP non-turbo diesel weigh?

Saw a girl in a gas station with a new Dodge Dart. Cute little thing [both]. She said she just got back from Canada. Got 36 MPG. It had a 1.6L turbo and a 6 speed stick trans.
