How dare you missed an important point into his latest "feature thesis lecture" notes    :

Wastegate is open before turbo kick in yo

Volvo is in deep shit, the drive-e range of engine timing belt driven. I guess the slipping that "makes" it more efficient??


If wastegate is open, where can build up enough exhaust pressure for the turbocharger to reach surge line?

Unless, it's a new secret proprietary invention of electric motor driven turbocharger that has a specially made on/off switch. But then, if that's the case, why the heck need exhaust driven turbine and wastegate? Normal exhaust ducting kan dah cukup? 

Wakau, tiba-tiba "activated", the car "activated" "warp speed" to send you (and maybe some innocent souls) to heaven from the corresponding epic torque steer and loss of traction.

Seems like cannot work, if the wastegate closed at elevated rpm, the exhaust pressure will be quite high. But if your boost limit set too long, the wastegate will definitely buka balik in a very short moment of time. If not, the elevated exhaust back pressure will stall the engine.

In your proposed setting, the car will almost be like a running hi hat...tsss...tsss...tsss...tsss.....

i trying my best to understand ....

i think it is left OPEN most likely... so that cylinder 2 and 4 can have lower pressure... OH wait ... where is cylinder 4 ...   

u also join the bandwagon ? lolzzzzzz

remember.. the objective is to show jay bodohness....
