turbo timer?

[netherland24]

im just curious...

might be dumb or might be alright

but putting a turbo timer on a supercharged motor...

any input?

Full Auto turbo timer allows your vehicle to idle the engine for a specified period of time after the key has been taken out of the ignition. This allows your engine oil and turbo to gradually cool down and prevents turbo damage.

what effects would something like that do too supercharger? wouldnt it help longevity?

- i ask cause i dont know..

thanks

yes, it will help.

it will help even with an NA engine if it's driven hard- it can be pretty important in the summer when it gets hot outside and you blast it at a constant speed on the highway.


an easier solution for the idle cool-down would be a remote starter. many remote starters allow you to press a button and take the key out of the ignition after driving and it will keep the car idling. The amount of time idling can then be set by you.

That's what I do when I drive my car hard.

Or tow it hard!! lol

word. i use my Clifford Matrix 3.5 remote since the turbo timer is built into the alarm. before i turn my car off i push the bottom 2 buttons on the LCD remote ("trunk release" and "remote start"), the turbo timer sequence starts, and i take my key out, arm my car and leave.

default programming sets the turbo timer for one minute. pretty much the same as an aftermarket timer.

well i dont wanna put remstart on this 5spd...

i got a great deal from a shop for 50$ for a HKS turbo timer V1.

Dont waste your money, it wont do anything. The reason turbo cars need them (large turbos) is because the engine supplies oil to the turbo while its running, if you shut it off before the engine idles and the turbine slows it will wear faster and become damaged. The supercharger uses its own oiling system and therefore wont have this problem, plus being belt driven it never spins faster than the engine speed its at so it wouldn't matter either way. Save $50 for an oil change.

The purpose of a turbo timer is superfluous in all applications... conditional on your behavior with your vehicle.

All you are doing with a turbo timer or remote/timer "idle-out", is exhibiting your "laziness" and "inability" to properly "spool down" your turbo or ANY vehicle for that matter after either HARD DRIVING, or otherwise HOT ENGINE and/or HOT TURBO temperatures. The killer in a turbo car is the "HEAT SINK" that is residually present in a HOT turbocharger... one that has not been allowed to "cool down" from it's HIGH RPM state, which is ANY time you are driving, even if you are not "on it hard". (Of course, the degree of heat is LESS under normal driving conditions, and not likely to cause major harm if the car is shut down "right away" after driving... but after HARDER or more SPIRITED driving, the temperatures can be not only extreme, but downright DESTRUCTIVE to oil and components. (I've SEEN mine glow red briefly after some hard-charging 16psi bursts... of course, I let it spool-down and idle for some length before shut-down) The purpose of IDLING your vehicle after "parking" is to let the oil continue to circulate through the turbo housing and COOL down the components of the turbo by disipating heat until an "acceptable" temperature is reached... trust me, the TURBO is still HOT. If you do not allow the turbo to "IDLE DOWN" in this way, you can risk COKING your oil, or "COOKING" it, wherein it breaks down and "gums up" on your turbo innards... or otherwise obstructs the oil flow within the turbo. (Although many synthetics are MUCH MORE resistant to this phenomenon than organic oils...) Great way to damage your turbo.

My point:

You don't NEED a timer or idle-out remote setup... you just have to complete your drive under LOW LOAD or MELLOW DRIVING conditions for the last few miles or minutes, (depending on how hard and hot you HAD been driving...), and/or when you arrive and park, just SIT in the car for a minute or two (or three...) and let the car and turbo idle-down. (I have done this for over 10 years, with NO oil/turbo related failures of issues...) I have found that this couple minutes is an opportunity to "take inventory" in the cockpit... shut off various devices, check NOS arming circuits... run through a crisplist of checks related to EGT (exhaust gas temp - which I allow to cool to 800 degrees before shutdown, as it is taking temp. at the turbo outlet downtube elbow, and reflects "heat-sink" dissipation in the turbo core as well...), oil pressure, idle level, independent fog switch off, stereo system attenuated, heater off, EVC (Electronic Valve Controller - boost) dialed to my desired start-up setting, HKS TEMS IC controller reset to "auto" mode... Bearcat Scanner State and HP channels reset... etc, etc... HEY, what do you know... car is cool now and ready to exit.

The "ritual" becomes second nature, and provides a calculated opportunity to really "know" my car after every drive. Actually, I repeat a similar routine with the vehicle as part of my "start-up/warm-up" procedure. I NEVER hop in a cold car and put it in drive... my rule of thumb being, "when the temp gage BEGINS to move, you can place some load on the motor"...


That concludes crispcooling disertation dimentia 101 for today...

turbo cars need turbo timer because the turbo is very hot (400c - 700c) and it needs engine oil to recirculate inside of it to bring the heat away. Also while engine still running, the water pump will also actively to bring the coolant to cool down the turbocharger and engine.

anyway, my point it is waste fo money for you because your car and charger does not get that hot. also, does any engine oil or coolant goes into your supercharger?

[netherland24]

im noob to this stuff thanks for the information guys...

i will now do more research. on what parts to put in.

Joe, I believe the TRD SC does use oil, but it's not routed from the engine oil, it's separate, no feed and return if you get what I mean.

Furthermore, I have no idea in hell what the purpose of a turbo timer would be on a supercharged car. Wanna cool down your engine? Shut your car off!

Turbo timers are used for the health and longevity of your turbo. They get much hotter than I can imagine a SC gets and also you have to worry about shaftplay arising in a beat turbo among many other things. Realize turbos spool to RPMs in a ridiculous range, tens of thousands, and should be slowed down gradually as well, an idling car will do this. And they get HOT! I have never had a supercharged 1MZFE nor have I ever seen one in person, but can't imagine any problems with overheating components.
