I recently learned that warming up your car in the morning will cause engine damage eventually due to the engine being forced to operate at a low effeciency. Because the oil isn't properly heated at idle it will cause damage to the piston rings and valve seals. Is it possible that could occur while letting you turbo cool down? You don't think so, but I just thought I'd run it by you guys. Thanks!

No.

Better improperly heated oil at idle than at WOT, 8000 rpm.

I dunno about you, but my car idles at about 1500-1800 when cold...

700-800 when warm.

Proof enough?

integra owners manual states that it is unnecessary to let the motor warm up for more than about 60 seconds, regardless of outside temperature. I usually let it go for 45 seconds-1 minute then get on my way. Nothing to worry about.

Maybe I'm wrong but I never let my car warm up. Now, I don't go past 3000 rpm until it is, but I'll still drive on a cold motor.

My car feels so much faster when its cold/barely warmed up, hehehe....

Total'd GSR

I'm the same way... I just turn the ignition and go.

running the car cold and running the car cold under boost are 2 different things.
i'll run my car cold but no boost till temp is up.

I wait till my VAFC reads 1450 or lower rpm before I leave in the morning. I can't imagine why letting the car recycle the oil back into the pan(by usng the turbo timer) would be less than benificial.

Its called a turbo timer not a damn engine timer. Its to let the oil cool and coat the turbo. Secondly, your talking about warming up not cooling down your engine even so what does it have to do with a turbo timer? Third, the manual may say a minute but I usually wait at least 2 minutes because we're not dealing with a stock car here. There is a turbo we're trying to prolong and the turbo spins a lot faster than 8000rpms.

When you warm up youe engine you're just letting it idle. When you turbo time you car you just letting it idle. The major difference is that when you warm up your engine is cold, but when you turbo time your engine is usually at standard operating temperature. By the way, the idiots in my neighborhood let their cars warm up for as much as 30 minutes on cold mornings.

WTF
pass the crack this way dude!

lol


i let it idle for about 1 minute b4 driving, or sometimes i never
let it warm up, regargless of how im feeling that day i never go
over 3000 rpm till shes totally warm.

uh, i think idling the car for 30 minutes would be bad for any car.
a 30 minute idle means no air/water cooling....that means
(your coolant is heating up pretty darn fast)
cars have to be under load to properly reach certain
operating temperatures. idle just aint gonna do that.!

i think it takes a 5 minute drive with shifts under 3000
to warm up my engine...but thats just me...

Pritos

some funky logic going on here

Total'd GSR

My friend with a '93 Talon AWD had his GReddy turbo timer set for 3 minutes for normal driving and 5 minutes for hard driving I finally convinced him to lower it to 1:30 for normal driving.

What do you guys have your timers set at?

Since I've removed my water valve, it takes my car forever to warm up, so its actually quite essential that I start the car and let it warm up for about 10 mins before driving it. If I don't, it stutters and drives like a bitch.

downpipe

the best way to warm up a car is by using common sense...drive it easily until its warm.

turbopanda

that's what I mean though, under normal driving conditions, it will jump and stutter until its warmed up. so I just let it warm up and then I drive off, allows the breakfast in my stomach to properly digest while driving

I think you're confused? Warming your car up my be bad at first, but that's why they say that like 80 % of engine wear comes from starting it up. It's because your engine has no oil flowing thru it yet, but damn it's no big deal, and it's totally the opposite of letting a turbo timer idle the car after it's already warmed up-

There is already oil flowing and the car is idling at ~750 RPMS instead of ~2000.

So what on earth are you talking about?

PS-I let mine warm up for 10 minutes or so on cold mornings too so I don't have to freeze my *** off inside this poorly insulated car.

SW20 MR2

I don't warm my car up at all. I just take it easy until it hits regular operating temp. I don't remember the technical explanation, but an automotive engineer once told me that idling is arguably one of the worst things that you can do for the engine since it puts undue wear and tear on the valvetrain components.

I set my turbo timer for 1 minute for daily driving and 5 minutes after racing.

Smashback

Idling your car is better than racing it!!!!!!!!

Why is it so hard for some people to understand...

The point is that letting your car do it's high idle thing to warm up is hard on your motor because it's cold, there is no oil on the bearings (all in the pan) and it's IDLING AT A HIGHER RPM THAN NORMAL IDLE, i.e. 2000 instead of 750.

Do you think that normal idling at 750 RPMS is harder on your motor than redlining your engine at 8000+ RPMS running 8+ PSI of boost? If so, you do not deserve a car. You are too ignorant and the Gestapo will arrive shortly to remove any cars from you

SW20 MR2

Ummm, I wasn't comparing it to racing. I was comparing idling the car to warm up as opposed to driving easy to warm up the car.

Dee

here's my warm up method!

pour a six back of Pabst blue ribbon in the petro containment cell
initialize my .666 sec countdown sequence
pump the gas 19 times
punch the start toggle located under the backseat cushion
blip the throttle to 16krpm 3 times just to make sure there are no small kids in my exhaust
then do a 20k rpm left rear wheel burnout outta my parking space!!
nothing like doing a rear burnout in a Hunda!!

Geez.. lighten up already guys!

Smashback

NO YOU LIGHTEN UP! I DO MY BURNOUTS AT 30K RPM SO THERE!
