Brake boosting (or left foot braking) is also commonly used with single turbo track cars on tracks with a variety of corners such that you can't quite tailor your gear ratios perfectly. Allows you to have a bit too high of a ratio for a given corner but still get good launch out of it. Works really well with formula cars in general given that left foot braking in a RWD car tends to induce understeer, and thus make the car more stable through the corner. Rick Mears won the Indy 500 four times by being a master of this, his most notable pass using this technique was when he passed Michael Andretti around the outside at Indy in 1991 for the win. He managed this using left foot braking/boost building despite the fact that Andretti was on fresh tires and Mears was not. Takes a lot of balls and trust in your car to make the best use of it in high speed corners like Indy.
