I was thinking about the SP diesel turbo cool down timer. Any thoughts? and suggestions?. I don't care to purchase and edge for the timer (even though it works pretty good)

SP diesel Do your self a favor and avoid them at all cost.

Need to know WHY ?

they are impossable to get ahold if you have a problem and they do alot of shaddy things, search the forums and you will see what ppl have to say about them and i was going to buy a cool down timer but the guys at pdi who built my truck told me in reality you dont need one as long as you are not shutting your truck down after a WOT run. just drive it normal the last min or so of your drive and you should be fine.

Why you think you need a cool down timer? Do you have a pyrometer?

I'm just curious, I have a pyro and have never had to let it idle more than a minute to cool down to under 400º, including the time towing my trailer when I pulled off into a rest area beside the highway.

Edge with Attitude has a timer feature built in. You can set a time delay or use temperature for shut-down. I like many others are still waiting for Qaud's solution with his Commander....still waiting...

doesnt BD make a timer, thought i saw that somewhere

I have a BD timer on my '06. Real happy with it. It uses both time and turbo temp to determine when to shut down and is easily adjustable. Check it out at BD-Power.com

Are we in such a hurry that we cant sit in the cab and watch the pyro for a few minutes to see it drop below 400* It just seems like a few dollars that could be spent somewhere else to me??? Can you guys tell me the benifits of a turbo timer?

I have the Isspro Turbo Temp monitor and its preset to shut the truck off at 350F post turbo, so it runs a while sometimes

We definately do have a cooldown timer for your truck. There are a couple of inputs that it will shut down off of. It will run until it hits the set temperature which is adjustable. It will run for a maximum of 5 minutes or until you step on the brake pedal. These kits are $150.

The exhaust temp is not the reason to let it cool down. The turbo must be cooled to avoid cooking the oil in the trubo bearings. Just because the exhaust is cooler doesn't mean the turbo has cooled after it has been working hard by towing or highway speeds. It takes a little time at the lower exhaust temps to cool the trubo.

I have a timer and I use it for other purposes, like stepping into the post office and leave it running and knowing it will not be driven off as it will quit when the parking brake is released.

Hmmm, okay, that makes sense, my bad!

So, assuming the EGT's are 700 when you pull off the highway, how long you think you need to keep idling once the EGT's are under 400 to cool the oil enough?
Maybe we should be buying "turbo oil temp gauges" or something¿
Is there a fitting there we could stick a gauge into? That would be an intersting thing to see....

For me, the point is to allow the turbo to spool down... not just let the oil cool down. But both are worth considering, since they are intertwined.
It takes 60 sec in most cases to do both, IMO.
I don't care for the 400* (EGT) number... since most non synthetic oils are near their flash point at that temp. This assumes that heat soak allows the standing oil to get that hot; a fact of which I'm not sure. But why take a chance? I allow cooldown to 300*.

I do know if you shut down quickly after working your CTD hard and then turn the key back on 30 sec later, you will see the effects of heat buildup... on your pyro.
