Turbo "cooldown" before ignition off? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

gdrider77 · 08-27-2013, 08:12 PM

So title pretty much says it all, i remember in the past on other turbo cars, recommendations were made to let the turbo "cool down" before turning off the ignition.

I am thinking/guessing this is in relation to the bearings and oil in the turbine still spinning without lubricant?

Anyone do this? Thoughts?

I still do right after some WOT, although w/ synthetics & technology, it's not as important as it used to be.

Regular diving--don't bother--it'll just waste gas.

Turbo timers....ahhh the old days lol!

I usually don't 10/10 into my parking space in front my house lol.

Always drive very slowly as I enter my neighborhood, don't want to shit where I sleep you know?

Its good practice to not turn it off right after WOT, but since we use synthetic and our turbo is water/oil cooled, its not an absolute requirement to do it every single time you are about to turn the car off.

Just drive slow for the last 2 minutes or so before you turn it off..

I was tempted to purchase turbo timer, but I'll just practice taking it easy....hopefully

I was reading about this same thing recently since I just got the AVO. Tonight I let it cool down because I had just done some pretty hard driving, generally though I just drive slow at either end of my journey. Don't wanna spool up the turbo a bunch when the engine is cold either.

Turbo timers are kind of a thing of the past with new tech no?

whitefrs · 08-27-2013, 11:39 PM

i take it easy the last 5 min of driving and just let it sit for 30 sec

Does it include an electric pump to keep coolant circulating after shutting the car off? That would really negate the need to keep it running unless you were driving it really hard.

You are basically describing what a turbo timer does and no, I don't have an electric pump to keep coolant circulating in my car. I take it easy about 2-5 minutes before turning the car off everytime.

The joy of a remote start system, once parked, remove the key from the ignition, the vehicle will continue to run for 30 seconds after all doors (and trunk) have been closed.

Kills 2 birds with 1 stone.
