A normally a turbo has a lot less inertia, it doesn't have the inertia of the substantial chuck of magnets rotatingecapox wrote:I bet you are right. Throttles open or bypassed and stored energy is discharged by spooling turbo. I'm assuming that the oil pumps would have to be runningas well in order to lubricate the turbo during this brief discharge.neilbah wrote:Re the sound entering pits,
could the turbo be discharging the stored energy from the kers to make it safe in the pits?
most road cars probably dont idle as high as an F1 car so shutting off the engine the turbo would not be spinning so fast?
for turbo to spool down like that then all restriction must be removed surely so im guessing the compressor side is bypassing throttles and the lack of back pressure with the short and large bore exhaust helps but maybe a clutch is being disengaged on the exhaust side too?
Very rarely do you hear a turbo spinningso quickly without the engine running pretty hard as well.
in the MGU-H
though it is maybe a bit surprising that they don't have some sort of shut-down program that slows down the MGU-H before they stop the ICE since that it mechanically linked to the oil pump
