Idling Turbos

Kyoshi71 · 11-20-2006, 09:13 AM

Does anyone think it's a good idea to:

1) Idle a 335 after hard driving to spool the turbos down and lower temperatures?
2) Leave the car running instead of constantly starting and stopping if your just buzzing around town (and if local crime is controlled)??

Maybe my thinking is a little archaic. It's just little things I remember regarding the care of turbos.

Just plan ahead...When you push the pedal to the metal, leave some room for some good old "GrandMa' Style" driving

and you should be fine. Especially with the pump circulating after you stop your car.

Hello, it usually doesn't matter if you leave your car on after a drive or not unless you have been really, reallly driving it hard.
During under normal driving conditions, you would be ok as you would give time for the oil to cool down at stop lights or at light driving, but under extreme driving conditions, you may want to leave the car on for a couple of mins before suddenly shutting it off without letting it cool down.

i heard somewhere on this forum that when you park your car, before you turn off your ignition, you should tap on the acceleratore for a second, and then after the rpm goes down shut the car off. Is this a good idea for the twin turbos?

only if you feel wasting gas is also a good idea.

turbos should be cooled down but theres no need to go crazy with it, just a minute or two is fine if you've been driving about. Frequent oil changes to keep it nice and clean (and heat absorbent) is more important to me.

if you wish, I guess you can buy a turbo timer for the car..but the plot thickens since no one makes an ECU harness for it yet, and you definitely don't want to cut up the oem wires for that.

I have a turbo timer for my current car and will not even worry about it when I get the 335i. Under everyday driving, you will never get the car hot enough to the point where it should be an issue, unless you are driving with a very high spirit at night continously...even at that point crusing around for several mins will bring the temperature down to normal.

someone said in another post the car the turbos are cooled with coolant and when you turn the car off coolant is still circulated until they are cool.

^that is true. if you look at the coolant resovoir under the hood right after the car is shut off, the level will be less than where it would be when the car is cool since the coolant will still be in the "system".
