ok..i see alot of cars that has a psst sound when they change gear..wat is it that cause the car to have this...wat have they put in to achive this ??

Turbo sound.
Zhng brand. -
Its actually a device call BOV = Blow off Valve.Originally posted by snop_coolz:ok..i see alot of cars that has a psst sound when they change gear..wat is it that cause the car to have this...wat have they put in to achive this ??
Normally driver with turbo charge car will install one as it helps to improve turbo lag due to air flow.
Its not because they change gear got the sound. Its actually from the fast acceralation and they depress it fast. Thats what I know about it.
But then again, there are things call speaker BOV. Saw once on a 1.6sunny. When he overtake me from the back...i still tot what car sia. Speaker are much louder and sharper but the sound not as long the original. Can hear the difference. -
LOL @ the sunny with the fakes. yea, it's the BOV but i thought the function of the BOV is to relief pressure from turbo?Originally posted by drumstick:Its actually a device call BOV = Blow off Valve.

yah i thought is when u talk ur foot off the accelerator then got the psst sound...Originally posted by yeehaw:LOL @ the sunny with the fakes. yea, it's the BOV but i thought the function of the BOV is to relief pressure from turbo? -
its speaker la....

planning 2 put one in yr car??Originally posted by drumstick:Its actually a device call BOV = Blow off Valve.

then wats a boxer engine?

Haha greater acceleration = more boost, and the psst sound by the BOV is caused when the accelerator pedal is released (ie when changing gear) thats why you hear the psst psst sound. Even if you dont change gear u can also induce the sound, just rev higher and release lor.Originally posted by drumstick:Its actually a device call BOV = Blow off Valve.

Boxer engines of up to six cylinders have proved highly successful in both automobiles and motorcycles, and continue to be popular for light aircraft engines.Originally posted by snop_coolz:then wats a boxer engine?
One benefit of using a boxer engine versus a V engine is that the design provides good balance because each piston's momentum is exactly counterbalanced by the corresponding piston movement of the opposite side. These engines can run very smoothly and free of vibrations with a four-stroke cycle, regardless of number of cylinders, and do not require a balance shaft or counterweights on the crankshaft to balance the weight of the reciprocating parts which are required in other engine configurations. But boxer engines tend to produce more noise than inline and V-engines because valve clatter is not so well dampened due to lack of covering by air-filters and other components, and produce a larger torsional vibration than a V engine, and so tend to require a larger flywheel.

and boxer engines dun tend 2 rev high as a in-line or vee engine cos of vibrations...even if u say its balanced...and they dont have much high end power but they've got low end grunt....

Put speaker bov... i might as well put a good ICE inside the car... on power bass...still can feel strong vibration...lolz..Originally posted by AE86tofu:planning 2 put one in yr car?? -
its actually the pneumatic system tat is working, juz like those on our buses.
psst psst. -

those cars got psst pssst because their tyres are leaking air

The correct technical name for the boxer engine is "horizontally opposed engine". Half the number of cylinders on the right of the bonnet, half on the left of the bonnet (like engine split into two lah). And their spark plugs.....wah lan eh, very hard to find. hahahaha....Originally posted by snop_coolz:then wats a boxer engine?
The sound from the boxer engine is nicknamed "boxer note". Some people complain that its too loud. There are two simple solutions to this:
(1) Spend S$1 on a pair of ear plugs.
(2) Use your left hand to turn the music volume up. -
So ez to get that psst psst sound. Last time army drive 3 tonners, release hand brake can get that sound liao.. lolz.. want even louder, use the 5 tonners and press air release from tyres. The sound from the air tank confirm the loudest. Even louder then some cars which did exhaust operations.. lolz

our buses also have BOV
think some of those heavy truckers have also. next time u see time, pay attention to their sound. some of the heavy truckers have some good sounding BOV
