Nope, the squeaking noise was made by the bypass valve, which I ****** don't know what it was exactly...
Some S1s also had an exhaust bypass valve, i.e. a bypass valve that did recirculate the intake air on throttle lift-off in the turbine, to keep zee turbo spooled. Their sound could be coming from that too. I'm absolutely positive that the sound didn't come from the transmission at all though...

I'll have to get my Group 'B' video out now!
You don't know how I hate watching Walter Rhorl dancing on the pedals....
Then there's Michelle Mouton to watch as well.
It does sound a bit straight cut to me but I could be wrong. I'm too used to Minis with SC/CR gearboxes!
If it sounds anything like Marks then its gonna sound awesome!!

So this is the RS2/S2 guru...only now saw the nick.
Anyways,wasnt the S1 sound caused by the wastegate "popping open"?Since they didnt have a BOV,i would imagine the sound was turbo stalling.I could be wrong but it makes logical sense to me.

They did have a BOV. That BOV was recirculating the compressor outlet air into the turbine inlet on throttle lift-off conditions to keep the turbo spooled.
Nowaday's WRC cars do make the same chirping sounds and I can't imagine a WRC engine with no BOV, given how small the turbos are on these cars, I guess they won't even last for a special stage with no BOV, nevermind a rally...
