if a turbocharger gives more horsepower will it save gas like does a turbocharged v6 300 horsepower car ?

Question

get better mpg than a v8 300 horsepower car with out a turbocharger?

Answer 1

If driven under light load conditions a turbocharger will use less gas. You will save even more gas if you switch to the best non-leaded fuel you can find.

Reason: All cars produced in the past 15 yrs. have a device called a knock sensor which electronically retards the the ignition spark advance if the motor senses a ping or spark knock. When the spark advance is decreased by the knock sensor power and economy suffer. This is extremely important in a turbo charged gasoline engine. There is no upper cylinder lubrication as diesels have. Combustion temperatures exceed diesels by 200 - 300 degrees. High octane fuel protects the motor and keep combustion temps lower.

If you do not mind feeding the engine more expensive fuel I'd go for it.

Answer 2

It really depends on how you drive the car. A smaller engine with a turbo will have slightly better gas mileage if you're just putting around town. If you're on the gas they wont be all that different though.

With a turbo, you only need more fuel as the boost comes in. Before that, they're basically a lower displacement engine that is using less fuel.

Answer 3

yes, turbos are more fuel efficient that normally aspirated
( NA ) engines. obvoiusly since you are pumping gas into 6 and not 8 cylinders you will save gas mileage. turbos give the most fuel efficient bang for your buck. example, a Subaru WRX STI is a turbocharged inline 4 cylinder engine which produces horsepower numbers similar to that of a NA corvette with a V8.

Answer 4

Nope, they will be the same.... and remember it takes gas to make horsepower.... so the more power the more gas you will use.

Answer 5

its basicly the same.. but the turbo saves more (a bit)
