NEVER run an engine with the oil drain out, and NEVER let it drain 100% unless you have it out on a stand for dis-assembly/rebuilding purposes. Lack of oil in the bearing journals and surfaces is the number one cause for bearing wear, and can cause SERIOUS damage.
Car should be at normal operating temperature when the oil is changed, and especially on turbo cars, you should be pouring some oil into the fresh filter before installing it, as well as using a filter that has an anti-drain back valve(OEM, K&N, some Mobil1 filters/etc). Without the filter having oil in it on initial start-up, there is a moment when you have ZERO oil pressure, and thats where the damage occurs.
It's also a good idea to disable the spark, and crank the car until your oil pressure light goes out immediately after an oil change. This will ensure the filter is full of oil, and all of the bearings are safe. Doing this is the best way to make certain your bearings are safe and sound. Especially on turbo cars.
Once you've drained the oil, replaced the filter, re-filled the oil(typically to 1/2 qt to 1qt below max level), primed the engine, it should be started and left at idle for 30-45 seconds, and then turned off. Then, let the vehicle sit for 3-5 minutes(VERY good time to check the rest of your fluid levels and conditions, filter cleanliness, belt and hose conditions/etc), and check your oil level/top off as needed.
This is the procedure coming from a technician who has worked in the field for more than 10 years. This is how I've always done it, and it's never let me down.
Hope that helps!
