E55 supercharger air flow increase
hi. yesterday i removed the supercharger to fit 82mm TB. and while at it, i couldnt help it to notice these "air restrictions" in it when i took it appart. logically i think they are to limit flow and increase boost. is there any other reason for those in the right bottom and above corner of the rectangular hole?
i am thinking of removing them, neatly to increase flow and increasing crank pulley size to compensate. what do you think? has it been done before. also i was thinking to increase the size of the hole by shaving 0.5cm. and polishing it.
and what about the sc oil, should i change it? i smells nasty in the boot of the other car
waiting for your chimes before i go on...

This is thinking out loud, but those extra pieces may be to help direct airflow down the guts, prevent extra turbulence, help with resonance or limit air sliding down the sides.
Pure speculation. Id hate to see you modify it and make it worse. Would be great to see an improvement though

Cleaning up the TB inlet and porting the SC to air tank ports helps flow as well. Just in case taking apart the sc is more than you would like to tackle.

I have my blower ported by stegi, the link yacht-master posted is actually my blower lol he has several pictures of it on his rebuild album i didnt do before after dyno for it, but there is a difference more air flow runs more efficient.

I guess you would weld each hole on the right and left side tabs. For the life of me I don't know why it would get louder......but I would do it I think!!!!
