squeaking noise from WRC cars

[zerodegreec]

During the overrun/breaking into corners you hear a squeak come from the cars. Is this from the anti-lag? its not the sound of a blow off valve, its almost like a suspension noise... Ive been stumped for ages as to what this it, every car seems to have it.

Just answerd your own question, antilag

[zerodegreec]

so what part of the anti-lag system causes this sound?

[Jimmy Magnusson]

Whatever it is, it hardly sounds great, does it? Compare with ~10 years ago...

Bring back the sound of the Escort WRC, popping and banging all over the forests

It's not anti-lag It's the wastegate as Larry said. The Subaru's of the late 90's were great for it

Yep as said its the external wastegate on a GpA/World car that is opening/closing very quicky and releasing very high pressure air, sometimes back to atmosphere, that gives you the noise.

GpN cars (and most production cars) have the wastegate internal to the turbo and you dont hear the pressure release.

Love the sound of this one.. Classic RS 500 with antilag! Both whisteling and bang bang! Could it be better? Sweet exhaust too
