Turbo Timer for CRD

[Rubi Jane]

Anyone installed on into their CRD? If so what brand did you install and how did the install go?
We're looking at this unit, real small and unobtrusive but has some good features.

I've never installed on one a liberty, but I have on cars equipped with turbos.
I think the last one installed was Greddy. The install is relatively simple, basically deals with the ignition wires. Hardest part is finding the right wires, its not hard at all, it just takes a little time.

I'd hold off on buying a turbo timer. It seems that some cars don't need one. I recently bought a WRX and the cooling design of the Subaru turbo is superior than that of the old school Toyotas, and I've never seen one on a diesel. Since the CRD is new to the US, I would wait until some of the other people have had one. IMO.

[SRotblat]

superior technology or not you can always benifit from allowing cooler colant/water to flow through the turbo which can be done by use of a turbo timer.

I've got one on my modified GTI, and if I had a CRD I'd try to get on on that too.

[styng88]

Not to get into a pissing match, but the only benefit MAY be extended turbo life. There are NO performance gains. On a VW a turbo timer is a good idea, but like I said, some vehicles won't need one.

[styng88]

Another idea; check the owner's manual to see if there is a cool down procedure for your turbo. If there is a section dedicated to this, then go ahead and get the timer. If not, save the $100 and your time.

[Rubi Jane]

The manual does have cool down procedures so that's the reason for the timer. It's just so much easier to have a timer and if it extends the turbo life then great, otherwise it's probably worth $100 just for the convenience.

Problem is now to find the wires...thinking of asking the dealer to install or getting a performance shop to install.

No need for a pissing match, as it doesnt seem you've got an understanding on why you'd want a turbo timer #-o. All turbo vehicles regardless of any suposed superior technology require different cool down procedures than non turbo cars, ie cooling off the turbo via coolant or water flowing through it. All a turbo timer is doing is allowing that to happen, there by giving the turbo more life. If your expecting performance gains from this type of mod you've got some more reading to do!

[styng88]

No, I DO understand what at turbo timer does. Will I buy one for my WRX?? HELL NO. For me, it's a waste of gas. If I ever buy a CRD, I'd think about it. So no, ALL TURBO MOTORS DO NOT NEED A TURBO TIMER.

[SRotblat]

ok have it your way mj.gif

[Skidplate]

In my sig is what I commute in (the powerstroke). I find that when I get to work or the store, you can almost watch the temp gauge drop when you park. Let it idle down for a minute or two, drop your seat belt, turn off lights etc and you should be fine. Diesels cool off a lot faster than a gas engine. The only time I let it cool for an extended time is if I pull off the freeway and then after a few moments at idle the temp has fallen enough to shut it down. Plus with the cost of diesel anymore...
just my 2 cents...

[Bennett]

Well here's the real deal on turbo timers...

The basic function of a turbo timer is to allow the vehicle to idle the engine for a timed period, with the ignition key removed. This allows the engine oil and turbo center cartridge to cool down and prevent internal turbo damage.

If you don't drive hard it really isn't necessary, but if you do occasionally drive hard just leave it run for 2 minutes before you shut the engine off, much cheaper turbo timer that way.

Why a turbo timer in a Jeep? Is it necessary? Unless you plan to race the engine all the time, I think it's a waste of money unless you have an import Honda or sedan of that sort but in a Truck? It would probably be neat to have it if you have a Turbo engine otherwise, allowing your car to idle for a bit before you turn it off is just the same.

the CRD is a turboed engine #-o

[Rubi Jane]

Interesting comments but honestly...I understand what a turbo timer does. The Sport CRD does not have a turbo temp gauge so I can't see it cool down. Sure I could sit oin and wait 30 sec to 2 mins (depending on driving) to shut her off but why I'm looking at a timer is a matter of convenience for myself to extend the turbo life.

Waste of money on the timer or the little extra diesel it's gonna burn? Well, I guess I'm not cheap! We typically invest in our vehicles and run recommened maintenance/protective procedures and for that we have appear to have little to none operating issues over the cause of our vehicle's lives.

What I wanted to know was if anyone had installed one not a friggin' lecture that I don't "need" one. ](*,)

[yoda13]

Relax,

A lot of us make mods that we don't "need." If I had a CRD, I would be interested in something like this, simply because I love gadgets. I have seen these on diesel motorhomes, but don't know that much about them. If you get one, I personally would like to hear about your experience and perhaps see some pics.

[gsbrockman]

You could always ditch the Turbo Timer in place of something really useful...actual gauges. I have a 2003 Dodge RAM 2500 4x4 Crew Cab with the H/O Cummins Turbo Diesel & six speed. I have an AFE Magnum Force Intake w/ProGuard 7 and Torque Tube, EDGE EZ, and a better flowing aftermarket muffler. Before any BOMBing took place, I installed gauges (BOMB means Better Off Modified Baby!) boost, pyrometer, and fuel pressure.
Typically, on my Cummins Turbo Diesel, it's safe to shut down at 300* F or lower pre-turbo. The amount of time it takes to hit 300* F depends on load, terrain, outside temperature, speed, and a number of other similar variables.
Given the fact the CRD's come with 0W40 Mobil 1 Full Synthetic, I'm not going to get too excited about frying the turbo anytime soon. Just a little common sense and a few seconds of idling prior to shut down, unless the piss has been ran out of it, should keep the little turbo happy and extend its life alot.
The first pic is not the best quality....

Here is the turbo cool-down page from the CRD owner's manual.
http://img79.echo.cx/img79/540/cooldown4ht.jpg

It doesn't go into just how one measures the Turbocharger temperature, but I imagine placing my pinkie on it would be a bad idea.

I was surprised but the relatively long duration of the cool down. I can't quite see myself, racing into an interstate rest stop with bursting bladder, and waiting 2 minutes for it to cool down. I can take care of the entire reason for stopping in much less than 2 minutes.

So the dumb question: For years, coolant systems have had temperature sensor controlled electric fans that run long after the key is removed. Is this not a better answer than a timer that keeps the engine running?

So the dumb question: For years, coolant systems have had temperature sensor controlled electric fans that run long after the key is removed. Is this not a better answer than a timer that keeps the engine running?

No. The fans cool the radiator and the coolant fluids but do nothing to circulate the fulid through the engine as it cools. Thats not an issue for non turboed vehicles. For turbos though they are cooled via flow of liquid through the housing, because they spin at such high speeds (100,000rpms in nothing) the heat they generate is very high (my GTI runs ~1000-1100 and higher when under boost). The liquid used to cool the turbo is also as such much hotter as a result. If you shut off the car before giving it a good cool down the hot coolant can cool to rapidly and cake in the feed lines which will reduce the ability to properly cool the turbo as times goes on and can lead to turbo failure from heat. A turbo timer keeps the car running, which keeps the fluids flowing and as it sits without load it cools everything as needed, something simply running a fan cant do.

[melted]

So dumb question number 2: Could the turocharger be sufficiently air cooled using an separate bolt on electic muffin fan, or is there simply not enough heat exchange surface area to keep the engine coolant from caking? Maybe it's just easier to run the engine. #-o

[gsbrockman]

The turbo is typically cooled thru intake air at idle, as well as the circulation of coolant and engine oil. A fan won't help any.

What about putting an intercooler on a CRD :-k Now that be cool and give you more power!

After all that chatter of wether or not a timer is necessary no on actually even asked the right questions...it just turned into a urinating match.

I want a turbo timer in my CRD too -- I don't care if I spend $.05 of diesel fuel unnecessarily. It would be worth it in peace of mind knowing I'm doing everything I can to extend the life of a great vehicle.

Now, on to the technical how-to discussion - from my point of view there are 2 questions:

The keys have the silly 'chip' in them -- so if you remove the key, the engine will shut down, regardless of the ignition wire status. I've seen a company (can't remember who they were) that made a bypass for the chip sensor --

The second is identifying the ignition wire, and the emergency brake wire. Does anyone have a wiring diagram for this system? I knowing what wire is the ignition seems to be the hardest part so far...

-Gerry

[jinstall]

Wouldn't a customed burned chip do the trick on this? I find that extending the time on turbine cool down to be very interesting as I plan to drive my CRD in the 90-100mph range daily. 0w-40 is what I use in th race car so I am sure the $15 a liter Castrol race will work just fine in the turbine as well. 9hrs at 80-100mph can be tough on turbos if you do not let them cool correctly. Hmm turbo time that is another to put on the list. Have to see if anyone makes on here.

[emiperformance]

Another reason for having a turbo timer is that in my case SRT-4 and CRD is that the same oil that runs through the engine also runs through the turbo. if the car/jeep is driven under load of turned off after high speed/high RPM driving. the oil pump stops pumping the moment the engine is turned off and the turbo is still spinning (momentum). with no oil going through the turbo, the oil gets super hot with no circulation.
by leaving the engine idle weather it be by a turbo timer or by just sitting in the car and waiting, the speed of the turbines decreases to about 500-1000 RPM's on idle versus 45,000 RPM's on my SRT-4 and about 15,000 on my CRD.
I have a turbo timer on both.

Does anyone out there have a turbo timer on their CRD? I may be confusing details of security systems between my CRD and my other vehicle, but ... when you turn off your CRD and remove the key and lock the doors (which activates the factory security system) ... doesnt removing the key or arming the security system cut off the fuel pump until either the alarm disarms or the proper encoded key is put in the ignition?

Maybe all of that is alleviated in-lieu of the engine immobilizer by-pass module everyone is talking about?

I am interested in a turbo timer too, but weary of playing with ignition wires with all of these variables lurking out there.

[dnm45227]

If you have the sentry key system it will start for about 5 seconds then cut out, unless a key trained for that vehicle) is in or near the ignition.

There was some talk a long time ago about a turbo timer. The best I can recall is then one wasn't avaiable, and if you were really concerned you could just idle for about 30 seconds before turning the car off.
