Weird noise when turning wheel 100%

[coyfish]

Just noticed today that when i turn my steering wheell all the way to one side the car makes a woosh sound like a faint bpv noise. The engine also revs a little bit (100-150ish) rpms.

Im sure this is normal but can anyone fill me in as to why?

Thanks for any help.

welcome to the world of power steering.

power steering is powered off the engine, and will bog a little at idle if your turning the steering wheel.
