What actually happens when an Indy Car driver adjusts his (or hers) turbo boost?

Answer 1

The turbo boost controller is an adjustable pressure relief valve or "check valve".
It prevents boost pressure from opening the turbo's waste gate until the desired preset boost level is reached. Inside the valve is a precision stainless steel ball that is held in place by spring tension. During the turbo's spool-up (as pressure is building) spring tension in the valve is greater than the boost pressure pushing against the ball, so the ball prevents the air from flowing to the wastegate actuator.
This maximizes the efficiency of the turbo during the spool-up by using the greatest amount of air possible to spin the turbo charger. Most boost control systems waste air by venting much of the air out, even many factory boost control systems waste available exhaust energy during this crucial spool-up period. Once the turbo spools up to the desired boost, the valve opens, quickly opening the waste gate. Boost pressure is held at this level until the adjustment is made to increase or decrease the amount of boost required.

Answer 2

Well you pretty much answered it yourself, all u need to do i understand the not-so-difficult concept of a turbo. Increasing or decreasing the boost level is adjusting the air flow from the turbo into the engine.

Answer 3

My favourite motive force interior the present is Marco Andretti. He proved that he can rigidity in his rookie 12 months by way of ending 2nd interior the 2006 Indy 500 (2nd closest end ever) and turning out to be the (then) youngest motive force to win a substantial open-wheel race. with a bit of luck he may be the only to interrupt the "Andretti Curse" at Indy this 12 months. My favourite motive force from the previous could in all probability must be Ayrton Senna or Mario Andretti.
