Power steering leak Have a 99 ws6 Huron speed single turbo set up loosing power steering fluid every drive . No drops on floor put it up on my lift poked lil holes in rack boots no fluid coming out there can’t smell it burning on exhaust pipes or see it leaking under neath car or from the top side . Where is 10 ounces of brake fluid going in one day drive without showing no any signs . Any help would be very much appreciated . My power steering hoses are wrapped in heat wrap but no discolor or wet looking either . Thank you

If you don't see a leak at idle; from our experience here, I'd say:
89.9% probability - You have a power steering cooler and it's leaking. That P/S fluid is being driven (high pressure to lower pressure) into your coolant system. Check for the stock P/S cooler. (The rack return line goes through the cooler, which is inline to one of the radiator hoses.) If you have this setup, check the coolant dipstick for alien-like slime from this effect.

5% probability - Your P/S fluid is really dirty and is boiling over and out of the reservoir.
5% probability - You have a P/S pump leak that is ejecting fluid out the shaft seal under the higher RPM.
0.1% probability - Some low-life is siphoning off your fluid.

This car came from the factory with a Power Steering cooler, just like mine did. Odds are that it's also leaking, just like mine (and many others) have. It's very easy to check. Just open the hood and trace the return line from the rack back up to the P/S pump reservoir.

Yes it was the cooler. radiator fluid looked horrible replacing draining power flushing both antifreeze and power steering system didn’t look like it got into my power steering fluid it didn’t look bad but flushing it a anyway . Thank you for sure

Draining the P/S fluid is a great idea anyway. We've found that it boils over as it gets old. (Cooler, or not.) So, doing a 100% replacement every once in a while is a great thing.
That thread I linked above also has great information about cooler replacements. If you do a P/S fluid flush and keep on top of that and don't race the car - you probably don't need a cooler at all and can just remove the whole thing.
