Noob Question

[gach2]

Couldnt find the noob section here

(dont think it exists)

ive just got a r33 gtst (first turbo)

cars pretty stock cept the exhaust

and ive been told not to start the car immediately and drive

and i should let it warm up

in many instances im short for time and cant start it up and wait 5 mins

is this going to be a big problem

btw i do not boost while the engine is cold

dont give much throttle and change gears around 2.5krpm

[Kinks]

1. congrats

2. letting a car idle for ages is bad for it, it's a lot longer runtime for the engine when it's not in an optimum state (cold)

3. start car, let it idle for ~20 seconds to let the oil circulate and then drive off gently. I stay under 3.5k if possible and no boost until it's warm.

whoever told you to start your car and idle it for 5 minutes deserves a stiff backhander. you're not doing the car ANY favours.

[gach2]

thanks for clarifing that

im guessing he meant if i wanna boost let the car warm up first

+1 to above post some of the most important factors are having a car reach optimal running temp as quickly as possible.... too cold.. fuel is like sludge too hot and u overheat.... these days its fair cold so ye start the car 20seconds is perfect enough to then drive try get ur car to warm temp asap!

+1 for what has been said above. people seem to think that skylines (and most imports for that matter) are some magical monster race engines that should be treated differently to any other engine, when in fact they aren't. you will find that in japan the original owners would've hopped straight in and driven off on much colder mornings than we get here.

just keep it off boost until the temp needle has reached half way and has been there for a minute or 2.

hmm i usually warm it up for about a minute then drive off and keep it under 3k RPM

and start going higher when the oil temp reaches 80 ... gtr34 computer ftw !

Not even necessary to wait 20 seconds. The oil will be circulating within a few revolutions of the engine actually starting (don't forget you've been pumping oil while cranking to start).

Simply start engine, into gear and away you go. Every second that you delay is wasting fuel, and the excess fuel delivered while the engine is cold is risking dilution / thinning of the oil.

[tiberis]

an extra 20 sec isn't going to waste that much fuel, and it makes sure that oil has gotten through out the whole engine.

not sure about you but my engine starts pretty quickly, there is no way the oil has gone through the whole engine in the 2 or 3 seconds it takes to start. remember also that the cold oil moves a lot slower so it wouldn't run through engine and more importantly the turbo and be lubricating as it should that quickly.

if you have ever had an oil temp gauge in your car you would realise that your oil doesn't heat up much until after your water has come to operating temp.

i typically start car then go check my letterbox then hope inside and drive off.

the hop in and drive off thing also comes down to where you keep your car, etc. if you park it in a garage and you have to reverse down the driveway, wait for cars, and then go then you really could just hop in, start the car, once it is running just start going, because the first 20 seconds or so of the car running you pretty much aren't doing anything more than just idling the car. if you park out on the street and can literally hop in and drive off straight away then it is a different matter.

at my place i will hop in, start the car, let it run for a second and then select reverse. all i have to do is let the clutch out enough to just grab a bit and the car will start rolling down the yard, then i just need to let it out a little bit to clear the gutter. then i can just turn the steering wheel and start rolling fowards down the street. i'll just put it straight into second gear, let the clutch out at about 10kmh and just stay idling along in second until the end of the street (about 4 houses away).

I usually let the car sit for a minute or 2 just to let the fluids cycle through and then drive off and keep off boost for about 5 - 10 mins before boosting.

Once the car has reached normal operating temperatures, you are all good to go.

Before switching the car off, just drive off boost for a few mins and/or let the car sit and idle for a few mins and you'd be fine.

If you have been hammering it, give it more 'cool down' time.

If you're about to get carjacked, you take off straight away.

If you see a pretty lady walking by, you let it warm up for 40 seconds.

Average = 20 seconds (as already stated by Tom, Dick, Harry) gach

What about for non turbo cars, after some hard dosage should we still let the engine idle for a bit before turning it off?

[mad082]

yes sort of. the best thing to do with any car though is to simply drive sensible for the last km or so before you get to where you are going. the car will cool down better when it is actually moving than it will just sitting there running. this way also your brakes, etc will also cool down a bit and not have super hot pads sitting against a rotor in the one spot as this can cause warping, etc.

if you drive the last minute or so of driving normally then you can just turn the car off and walk away when you get there. this includes turbo cars.
