Turbo on car question?

Posted at: 2015-01-07 
The sound will be only for the blow off valves that release the pressure exteriorly. All turbochargers has BOV; most release to a bypass back into the intake (ie factory turbo cars).

If you turbo a muscle car and install an exterior release style BOV then it will make the sound.

Those are called blow off valves. when the car's engine speeds up, it pushes the turbo faster and faster. when you let off the gas to shift the turbo is still spinning very quickly and generating more air pressure. that pressure needs to go somewhere so a blow off valve opens up to let the air out. this air rushing out is the puff/hiss sound that you hear.

any car with a turbo and a blow off valve will make this sound whether its a small engine or huge engine.

on the Mclaren P1 supercar the gearshifting is so fast that the blow off valve doesnt open when you shift gears but it does once you let off the gas.

you can listen to that here.



That sound of a soda can is called a "blow off valve," it releases excess boost. Most "muscle cars," rely on big displacement, i.e. big engines to produce the power, and the max power is produced at lower rpms, as opposed to a turbo engine where the max power id often at higher rpm's so boost, can be generated, so a turbo is not necessary,

what you hear is the turbo spooling up. aka sucking in more air to force into the motor, which produces more power. sometimes muscle cars have a supercharger instead of a turbo, which essentially does the same thing except it doesn't need to spool up first, so the extra power is already there and ready.

yes, all car with turbo does that. the sound you here is the blowoff valve opening.

(I will apologize for my pore terminology in advance) so in racing cars or modified vehicles when a turbo is added and the gear is shifted it makes a sound sorta like opening a can of soda. Hopefully you know what I'm talking about. But if a turbo is added to a muscle car does it make the same sound?
