Power Steering Leak after Track Day

[maytag]

Hey y'all:
reviving an old thread, as it looks as close to my issue as I've found here.

I drove my '03 'S' today, for the first time since doing a track day about 10 days ago.

It seems I've developed a power-steering problem. Classic noises and heavy steering intermittently.

I've read about overworking the power steering pump at the track, but was of the understanding that this would first appear as fluid overflowing... which I show no signs of.

I have NOT checked the fluid level since I acquired the car in March this year. (yes, I'm embarrassed about that... since I checked nearly EVERYTHING else....)

My questions:
1. it seems (from reading) that I can hope to replace the fluid and the pump may still be okay?
2. Reading below, Redline Power steering fluid was suggested as an alternative to the pentosin CHF. Waddy'all know? IS this compatible? Recommended? Whata re you track-o-philes using?
3. Looks like I should probably go to an underdrive-pulley. Any adverse effects for a street-car that gets occasional track days?

Thanks for your help.
