Yes, they run in a sequential setup. The other turbo will start to spool up after a certain engine speed is achieved. http://en.wikipedia.org/wiki/Twin-turbo#Sequential_turbos
Yes, The turbo is just a booster but the engine makes a car run.
Yes, if you run around a track at a constant speed of 5 km/h, your velocity is constant because velocity includes both speed and direction. As long as you maintain this speed and direction, your velocity remains constant.
if the engine is not designed to run turbos it can do a lot of damage. a turbo engine has hardened internals
Yes!
no lol what a stupid idea
No, usually they conserve for the home stretch.
A turbo will increase your gas mileage, yes. It does not run off power from the engine, it runs off the exhaust system to boost engine power. Your engine has to work less for the same power.
A turbo timer lets some oil run through the turbo after hard use. You can accomplish the same thing by letting the engine run a minute before you cut the ignition.
A total of 30 seconds - assuming they run at a constant speed.
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
turbo timer if the car is turbo other wise the switch is broke and you need a new one
