If you don't want to let the car cool down, Just think of this:
If the tubo bearings get choked with oil residue, the bearings will loose it's "roundness" and will let the impeller to vibrate. At 85,000 RPM it will be catastrofic! the impeller will touch the housing wich is a few millimiters from the blades, break, and trow shrapnell to the intercooler and the engine at high speeds, causing horrible damage to the entire turbo/engine combination from the turbo housing all the way to the Pistons, head, and valve train including the interccoler, throttle body and a lot of electronic sensors... repair cost = $$$$$$$$$$$
If the damage is to the turbo only, I am sure it will be about $2,000.00 at least. Our turbos are one piece, not like others that you can buy the impeller/bearing cartridge at about $300.00 or the housing or even the exhaust manifold.
Again, If you don't want to sit in the car for three minutes, just spend $100.00, $130.00 if going with good mounting instructions and all the goodies for a simple installation, to protect your 26,000.00 investment from possible $2,000.00 repair in the future. Even if you have changed the oil to synthetic.
Think of it as peace of mind.
