From what I remember, it's smarter to cool down after exercise and stretch then.

(Love the OT! It's probably better to get this topic wildly off-topic though)

 

This is what you do so you dont waste your time. You get a alarm with option to remote start. so as your exiting your door, you start the car, open the trunk to put anything inside, wipe your windshield, and head off. Just make sure you're not on Gear..

 

haha, I have on occasion. I don't everyday because sometimes the traffic gets so bad it becomes dangerous to walk!

 

I'd be more worried about my diff warming up instead my engine. And the only way to warm up the diff is driving easy for a few minutes.

 

I let the car idle until the 2nd temp bar lights up. It more or less stops me from rushing and driving like a complete a@@, as most long islanders do. I had a subaru prior and the shifts were harsh on cold starts, so I carried over my "warm up" to the s2k. I might have a few problems in life, but time and gas aren't one of them.

Ok, Good call X-viper.

Was just trying to more be informative the manipulative.

Anyway.

Lets talk about cool down then.

1. If you just ran the car hard is it worth the time to let it cooldown?

2. Worth it if you are FI with a turbo or supercharger?

3. Worth it if your turbo is Ball Bearing? Cooldown still just as important?

Hey, I'm not phased if you're not. Still friends, right?

The subject of "cool down" can be much more important than "warm up".
1. I guess "hard" can be interpretted in many ways. For example (in a different car), I once aggressively passed a row of cars (maybe up to 5 cars) on the highway going up a hill. I made the stupid mistake of pulling over at an unexpected lookout within a few seconds after this manouver. My rad boiled over. Shutting off the engine stopped the water pump from circulating the coolant and the excess heat from running it "hard" localized in the engine's water jacket and the subsequent pressure was too much for the rad cap spring.

2. It's more important for a turbo to "cool down". Many turbos have both oil and water lines for the cooling jacket. Like an engine, this jacket can get very hot and a short cool down period helps to take the heat away. A supercharger is not so important for the blower itself, but I would still have the same considerations as in my first story.

3. Ball bearing or no ball bearing, the fact that a turbo has extremely hot exhaust gases running through it can become an issue, especially if the thing was recently run "hard". Ball bearings are not exclusively immune to "heat stroke".

It used to be that it was standard operating procedure (in my job) that after coming back from a call, any turboed trucks had to sit idling on the tarmac for at least 5 minutes before backing the rig in and shutting it down. Recently, the mechanical division has altered their thinking on this. It is now accepted that if we drive sedately back to the hall for several minutes, it is OK to just back in and shut down. In effect, sedate driving can be a good substitute for just sitting and idling for cool down.

 

Thats what i thought as well.

 

I NEVER depart until I'm showing two bars on the temp gauge. Common sense and a little understanding about the stresses being applied to all those parts making you you go fast tell you that a slow warm up is a good thing.

 

Thanks for the helpful info X-Viper. I historically have been a person that warms up the car but now that I live in a much colder climate I cannot stand sitting there freezing my a$$ waiting for the car to warm up. I will now take it easy for the first few minutes and waste no more gas.
