wired noise under hood after trackday driving

After driving on track, this noise is coming under hood.
But there is no noise on normal driving.

Heat and rpm is concerned, may be.

what kind of noise is this?

power steering pump noise?
pulley noise?

P/S fluid was under min lever. very little.

Engine condition is good.

Sounds to me like P/S pump. You may have boiled the fluid on the track and combined with the low fluid level, introduced a bubble into the system. Just my guess.

Try to re-bleed the system and flush out the old fluid while you're at it.

Thanks, Mvy.

Could you recommend proper P/S fluid level?
As you know, P/S Fluid always leak during trackday.
