Fantstic noises from a turbo car - 21st Jul 2005 12:38am
Reason other than speed to get a turbo
The noize
There are lots of noises u get from a turbo on your car.
1.Is the noise of the compressor spinning and the pressurised are rushing thru ur intake.This is the nice "whooosh" noise u hear as they accelerate
2.Dump valve-"Pppppppppsssssssttt" As the driver steps off the throttle for a gearchange and the pressurised air is dumped out of the intake and into the atmosphere to prevent turbo damage
3.Screamer pipe-An awesome noise that comes from the Blow off valve but travels through a pipe and gives a more squeeling noise as the pressure dumps. A good example of this noise can be found on the 2F2F skyline that Brian o connor drives in the opening sequence to the film. As he is speeding thru the streets on the way to the race
4.Turbo chatter-Not the most turbo friendly noise as it poses severe danger to the internals but if your turbo is strong enough this noise is created by having no dump valve/BOV at all. As the driver lets off the throttle all that pressurised air has to go somewhere so it forces its way back out thru the turbo the wrong way creating a sweet chattering hiss.Heard this in a drifting video for advan yokohama with a 200SX that has no BOV and its just awesome everytime he lays off the throttle
5.ALS-Anti lag is a system that keeps the turbo spinning at full speed even when braking/changing gear. This is achieved by chucking loads of fuel into the chambers when off the throttle causing uber-violent explosions, thus causing enough exhaust gas to keep the turbo spinning. All this creates a hell of a lot of flames, pops and bangs. Most often used on rally cars. Long term damage is a big risk
6.Launch control-Computer controlled lower rev-limit such as 5000RPM used for launchin from the lights, as the engine bounces rapidly off the limiter it pops and bangs almost purring ready to shoot off into the distance
Just incase anyone ever wondered why these noises are caused
