supercharger need turbo timer?

[scoupe]

my car has a toyota supercharger engine and i was wondering if cooilng down after hard driving is needed like puting in a turbo timer. if im not mistaken the supercharger has oil of its own. i normaly leave it about 20sec before turning the engine off.

yeah.it has alot of lubrication.ur running on a GZE rite?its a root SC.
i dont think u really need one.

coz the system is diff frm a turbo.ur SC has oil..but i doesnt need to "be somewhere else" (sorry,dont know the right term) where else for a turbo..the oil needs to flow back after running about..

i hope im right.:_:

I was using Toyota SC engine for the past few years and I've never install any turbo timer. The Toyota SC is a self-contained unit and no engine oil is flowing through it so turbo timer will be unnecessary.

Turbo timer is only needed on turbocharged engine. The reason, exhaust gas temperatures can reach a very high degree, and during hard driving speed the turbo shaft may reach over 100k rpm. So proper warm up and cool down is essential. To ensure that proper cool down is achieved, that's when turbo timer comes to work. The low rpm idling allows oil to continue to coat the turbo's bearing surfaces and allow them to cool their temperatures to a point below which "coking" occurs. Coking is the primary reason for turbo failure.

Just my lousy 2cents. Hope that helps. :shades_smile:

thanks guys for clearing this up for me.

Hi Bro,
What is the recomeded sec to set for turbo timer to cool down engine after hard drive for 4G93T? Thks.

Get the turbo timer with full auto timer like Apex'i Pen type.It automatically detect how long it has to idle the engine before shutting it down.

Oh.. I currently using Blitz. But I set the time for 40sec. is it sufficient to cool down the engine after stopping my car?

 

[Fluffy]

how long have u used that 40sec timing?

if till now it doesnt give u any probs..then okay lor.

 

[johnnygsr]

40 sec for 5-6 month. So far so good, but I scare later will affect my engine if the time is short to cool down. Plz advise or any how to test it?

For me:

Daily driving with some boost: 30 sec
Long distance driving (KLIA > 100km): 2 mins
Long distance driving (PG > 300km): 3 mins
Long / short distance with a lot of boost (Genting Highlands): 4-5 mins

 

[khoyos]

running daily boost of 1.5 bar, whack at every opportunity ( not 1.5 bar all the time). no timer. no problem.

no turbo timer yes... but I'm sure after whacking your engine at full boost, you don't straight away off your engine also right??

meaning got 'manual timer' loh... hahahaa.

I set mine to 10 sec but I always slow down before I reach destination, and normally I don't turn off the key straight away after I park my car...so idling time + timer time, there will be around good 30 seconds or more, should be adequate I guess.

Besides, my radiator is from other larger cc engine (1000cc more than my engine), so I guess the motor oil temperature is keep well under control.

 

[escaflowne]

a 30sec delay for ur engine after wack is actually better for your engine,NA,supercharge or turbo.BUT ya of course..turbo is a MUST la..

On the contrary, the engine gets more efficient cooling WHILE u're moving... So for N/A... just slow down before u come to a standstill (after heavy revving)... then off your engine lor.

If u leave your engine running... u're heating up the engine... not cooling it down.

The radiator fan turns on to simulate an estimate moving speed of 60km/h. So if u stop your engine, and the radiator fan is not turned on... then just off the engine lor... otherwise u leave it... the engine gets hotter and hotter and hotter till the radiator fan have to turn on to cool it down.
But if u stop your car... your radiator fan still running (quite unlikely laa)... then just leave it till the fan turns off before u switch off your engine lor.

Turbo timer not that necessary on n/a or root SC lerz... more of an accessory than a necessity.
