What is a turbo?

How does a turbo work?

What benefit does a turbo give?

A turbo is a mechanical upgrade made to engines by adding a cast iron almost like fan. turbos are made to increase power as well as give many other advances to the car such as better gas mileage and cooler engine.

A turbo works by exhaust fumes pushing through the turbo to activate the fan and compress the air inside each cylinder creating more air and burning fuel faster thus giving higher horsepower. their are many forms of turbos such as air to water intercooled, air cooled and some are even installed directly on the back of the car on the exhaust but this creates boost lag. boost lag is where it takes the compressed air longer to reach the cylinder's. boost is also calculated in pounds, for every pound of boost is an extra 10 horsepower. some people are known for putting extreme amounts of boost into built engines but this is extremely hard on the internals.

The benefits of a turbo can be seen in a array of things but also depends the type of turbo and the use of it such as how its tuned. running low boost can keep your engine running cooler as well as increasing gas mileage. as for running high amounts of boost increase horsepower for such things as racing. many high league racing teams run boosted cars as well as some manufactured cars come equipped with turbo. In reality turbos are not a necessity but a want in life, more important to car enthusiast in the end.
