Turning off car after speeding

zelmac · 02-13-2007, 11:23 PM

Is it bad to turn off a car immediately after you have been speeding? I've heard that you should wait a couple of minutes before turning it off, why is that necessary.

jonesthewine · 02-13-2007, 11:32 PM

Maybe it's not necessary, but giving the cooling system time to remove some of the excessive heat from an engine that's been driven hard is not a bad idea.

LOL, im not really sure if the car knows youve been speeding. You should ask it...

You should do the speed limit so that you can turn the car off right when your done driving.

***AbsoluteGG*** · 02-13-2007, 11:38 PM

i've never heard of such a thing

its bad if you have a turbo...but if you drive it like normal for 5 minutes, it should be okey...

On turbocharged vehicles, turning off a car after a hard run causes "coking". This is the cooking of motor oil left on the bearing. This can lead to premature bearing failure. Hence the invention of turbo timers, to assist with lowering temperature before shut down.

I woudl imagine the same principle would apply to NA vehicles, but just not to the extent of the turbo crowd.

I drive normally when I am near my destination.

This an interesting thread. I've heard this stuff before but i didnt believe it.

How does the turbo timer work??

It just keeps the engine running after you leave. Just for a few minutes, then turns itself off.

Batman & Robin always seemed to get away with it.

Why does this seem like something that can make the car easily stolen?

A turbo timer works after you remove your key from the ingition. Your sterrig wheel is locked. If you lock our doors when you walk away then it is just as easy to steal one of these cars as any other car sitting not running.

dsg2003gt · 02-14-2007, 08:31 PM

he never said he had a turbo...

so all of your posts are irrelevant.

That's what coolant is for!

The turbo timer in my RX-7 is wired into my ebrake. So If someone jumps in and tries to steal it, and puts down the ebrake the car turns off.

not only does it cause coking but with turbos when you run something that hot and just turn off the car. This obviously gets rid of oil pressure in the system, therefore the oil film between the bearings is gone. If you have driven hard enough those bearings are come in contact and actually fuse together. ( Bad)

I wouldn't recommend running any car hard and shutting it off. I have no firsthand reason as to why not to on an N/A car but you run into issues that might occur with Heat soak. Funny ways different engine parts expand and contract at different rates.

zelmac · 02-15-2007, 02:08 AM

I don't have a turbo, but if you have been at high RPM that could damage something, just by the change in temp.

Kidekat · 02-15-2007, 03:05 AM

In case the E-Brake was bypassed, I bought an Autolock to combat the car theft problem associated with turbo timers. Some Autolocks fits perfect on the clutch pedal, making the car not driveable.

If you are going to steal the car, you'll have to push it.

ReFlex · 02-15-2007, 10:22 AM

This turbo timer that you guys are taking about, does it come with all turbos stock when buying a car or that is a aftermarket product?

20strong · 02-15-2007, 10:28 AM

Mostly an aftermarket product to my knowledge.

***blue rocket*** · 02-15-2007, 04:51 PM

bleh, NA cars don't need to be cooled down after driving hard.

Eazy fix: Unless you're Michael Schumacher, don't "speed". Dumbass.
