[WTA]: Driving Habits

[whatdamn]

hi guys,

just curious to know if there is a right/wrong time to turn off the ignition after hard driving.

normally after hard driving and stuff, i'll sit in my car or let it run for about a minute or so before shutting down the engine having the mindset that it will help burn off the excess oil/petrol or whatever...let it cool down konon (just like a t/timer)

however, will anything happen say if i were to just park the car directly after hard driving and just turn off the engine...will that have an effect on the engine internals or anything?

would like to know your feedback on this pls.

thanks :)

I dont care much regarding this kind of "right/wrong time to turn off the ignition after hard driving" if got time only i will do....or if i remember..... hehehe......but we cant depent too much on right/wrong,... or if you really want to take care your car.... why not just do like the F1 ?......... but i think that is too much..... and if you said didnt care at all,well sometimes we do..... to name it i think that will be too many....... just turn off the ignition when you feel the timing/rpm drop to normal position.

Cheers

my car auto have 1min idle...

turbo timer...
thus prolong the turbo lifespan

For Turbo engines, after a hard drive, lubrication oil temperature will be extremely high especially the oil inside turbo CHRA's shaft.

WHen engine shift off abruptly, the heat soaked oil coke and hardens. Over time, shaft's performance detriorate and accelerated wear occurs.

As for N/A, the oil in the bearings of the reciprocating assembly (conrod, gideon pin, crankshaft) will also coke and harden when an engine is abraupt switched off without allowing cooling down time.

So its best to get a Turbo timer.

So that means we shud let N/A cars "cool off" first after driving? Like whatdamn said?

Well after driving like you're running away from a Tsunami.

if tat is turbo car....then it is suggested not to OFF d engine immediately....if NA then is ok

mine is normal drive will off after 15sec..auto timer ma......if hard drive then gotta see how hard i drive then only d timer wil decide d time to cool down....

 

[whatdamn]

joker,
my view on hard driving as in after an autocross run or a drift run...like going at high revs for quite some time u know?

anymore views on the matter?

 

[prodigy]

I'd agree that for a turbo charged car, its better to have a turbo timer to prolong turbine lifespan but i doubt its effectiveness when you're talking about NA cars. First, stock NA cars probably went thru few hundred thousand KM's of testing before being produced and i doubt your engine will have problem if you switch off immediately after a long drive. Else, we'll probably see tens of thousands of old cars breaking down every day.

 

[whatdamn]

i'm not saying a long drive...i mentioned HARD driving...as in constant high rpms in 1st, 2nd or 3rd gear. get it?

 

[cyclonite]

for NA cars just let the engine idle for a while before killing it lor.

for Turbo cars, most people have the wrong understanding of a turbo timer. Why do cars need a turbo timer? It's simple because the turbo turbine spins at a very high RPM during operation. When your car comes to a standstill the turbo is still spinning very fast. you need to give it time to slow down otherwise when you kill the engine the oil supply to the turbo will stop and the turbo will overheat.

 

[whatdamn]

mmm icic.

anyways sorry if there's any misconception due to the lack of info...i'm refering to NA engines :)

 

[Dino@Casper]

Good to let any car too idle for a while before switching off the engine.. read it in the NST car section sometime back

 

[whatdamn]

my thoughts exactly. :D sorry to wake u up so early today man hahah. blur...thought got class.

Anyways, Turbo timer is so drit cheap nowadays.

I think RM100 is enough for an ol school HKS or APEXi timer.

Then RM30 for install.

And if you are good in DIY, can install by yourself.

ooo ok.. But this turbo timer can be used to read N/A cars?

I mean.. it works for n/a cars rite? where to buy so cheap old hks/APEXi timer?

N/A car can put timer as well......syiok urself lo...

where to get cheap timer.....u can 5 it around ZTH at 'engine n performance' or 'interior' there.....happy finding o

yup i have read and imported engine tuning book .. is true for turbo charge as what joker say it will fry the main bering and the turbo bering and will cause shoter the bering life span.. so we need a timer to ide the engine to cool down the hot engine oil through the oil cooler......but for N/A not every engine need.. only for those extream mod engine and extream journy or on high rev engine so the engine oil heat up more than normal run ... so that need cool it down 1st b4 the engine oil fry the main bering...

read from mag, After the car done long distance travel (example, KL - Ipoh) or travel at high speed. Let the engine idle for 2 - 3 mins before turning off the engine.

And I try my best to warm up the engine in the morning for 1 - 2 mins before i start rolling the wheel :), just a personal practice.

Heh wanted to share with you guys, if you drive at high speeds for prolonged periods on a nice hot afternoon, next time stop just enough to shut your engine down and pull your dipstick. Mine was fuming... :) and no I was not running a turbo.

So think only turbo cars need to be cooled down before switching off?

The best explanation I can give is avoid rapid/subbden changes in temperature. If your have been speeding, wind down, slow down, rev down, WAY before you reach your planned shut off point. Thats my best advice. 5 mins of relaxed driving will probably cool your car far more than 5 mins of idling. Turbos timers are pretty ok. but I question how effective is the oil cooling when your not having air moving through your radiator and relying the fan only.
