What is the point of a turbo timer on N/A cars?

[JaCe]

Just looking at JDM Concept on eBay, and noticed on their Turbo Timer page they mention;


It is suitable for both Naturally Aspirated (N/A) or Turbo cars.

So now I wonder, what is the point? Am I missing something? Or does this just leave your car idling after you turn the ignition off and take the key out... I suppose it would allow me to leave my sound system on without having the key in but can't really figure out any real benefits otherwise?

You just have to remember that a TT is just a tool and is not even 'needed' on a FI car.

Some NA people after they track thier cars, like to cool thier car down so thier Oil and Water temps return to normal.

[JaCe]

That makes sense. I guess you'd have to be pretty serious about TT since there may be insurance implications.

the real answer is - there is no point, on an n/a car its a waste.

even on a turbo car, its not that hard to just sit in the seat while you leave the engine running for 60seconds.


a turbo timer's function is to keep the engine running after you turn the car off so that oil doesnt sit around the turbo straight away (ie letting the oil circulate when the turbo is not spinning so that it has a chace to cool down), because if it does, the turbo is significantly hotter than the block, which can cause the oil to degrade very quickly and turn to sludge - bad for turbo, bad for your engine too.

because n/a cars simply do not generate the same heat that a turbo does, the oil does not sludge when it is left in the galleries upon shutting the engine down, therefore a turbo timer is not necessary.

further to this, because the car is stationary, no air is flowing past the radiator/oil cooler (if you have one) and the engine itself, meaning that under bonnet temps are more likely to INCREASE than decrease.

maybe it cools down the engine quicker? coz itis being cooled by the radiator as well?

perhaps the driver wants the other features apart from acting as a mere simple turbo timer and paying for an expensive pfc or vafc

as quoted from the ebay link:

# bar graph for easy visibility.
# Full auto model which calculate the right "after-idling" time.
# Battery voltage meter.
# Accurate temperature meter.
# Lap timer / Stopwatch functionality

some turbo timers even show readings of fuel ratio or air flow or exhaust temp.

maybe people just like the rice factor?beats me hey.

nah, for the reasons i stated above, namely heat-soak, it doesnt. youd be better off spending 1-2km driving easy

[DLO01]

When stationary engine bay temps will increase, but the radiator fan is on and cooling your water. Your water and oil WILL return to normal temps. Your cooling system needs to be able to do this.

its for lazy people who forget to cool down the car and wanna take off as soon as the car stops.

N/A i don't think its really relevant, i use to thrash my car pretty hard and all i did was just turn it off still, never an issue.

It smore of a gimick to sell turbo timers to ricer boys

[hondajazz2005]

actually what is N/A ???

[dc2dc2dc2]

natrually aspirated ?

natrually aspirated ?

yeap....basicly translates to not forced induction.
not turboed.
not supercharged.

[dc2dc2dc2]

TT = purely wank factor

[Q_ball]

^ NOt wank factor... for convenience.
60 seconds in ur car... waiting for it to cool down, is fckn annoying!!
Especailly when ur ina rush!

[Limbo]

yeah but that only applies to turbos

true but i reckon their only useful on an electric water pump setup with temp control (and no mechanical thermostat)

that way the engine can be off but the TT will leave the electric pump and fan on...

[Elwood]

Remeber too guys, that with the TT you can just turn the car off immediately if you have kept it below boost/havnt been thrashing it etc city driving.

same with n/a..

[ek4-guy]

Only really wankers would use them at the race track after a race aswell.

From my experiance you never move too far from the car for the first 20mins after a race anways.

But yeah if your selling a product that has a wanker feature then why not advertise it wankers have money to. So i see why JDM Concept would mention it.

Did you read the first posts?

[<4n'D>]

for n/a applications, it tricks people into thinking your car is fast... or makes them think you're a rice boy.

total waste of money if you dont have a turbo.

also remember that a benefit of n/a over forced induction is that there is less importance in cooling down the engine before turning off

[dsp26]

^^yes because usually the turbo charger will be a lot hotter than the engine...

by letting the engine cool itself and circulate oil/coolant... that cooled oil/coolant in turn cools the turbocharger....

so yeah don't see a point on an NA track car.... only if it's setup to trigger electric water pump plus fan while car is off and no thermostat to cool the actual engine...

The voltage and air fuel side of the TT comes in handy.

Had our fun if anyone wants to continue the never ending TT n/a discussion search for the old LONG thread and take this discussion there. Closed
