Will Someone Explain The Turbo Saver

[NBowlin]

what is it? what is it for? is it a good idea or any of that fun stuff along those lines. thanks

Its what a car guy might call a turbo timer. what it does is keep the truck running for a predetermied amount of time after you turn off and remove the key. it allowes the truck to idle for 30-120 secs to keep the oil circulating and cooling the turbo down.





you can do it yourself by not runnign hard a few minutes before shut down or just let the truck idle for a breif time before shutdown if you were running hard.





BTW on the internet typing/posting in all capital letters is considered yelling and some people will let you have it for doing it. (i personaly dont mind) just a freindly FYI.





Happy motoring

I have a ISPRO turbo saver and am very pleased with it. The unit is wired into my exhaust piro gauge and keeps the engine running until the turbo goes to 300 deg's then shuts down the engine. Mine runs by temp not time. Just make sure you have the manual shut down wired in when its installed or you could have a problem if you have a engine trouble that requires emergency shut down a lost of oil or coolant. If you do not have the switch wired in then you will have to open hood remove fuse block cover ans pull a engine control fuse to shut down like I did when I lost my oil thanks to a lose oil drain plug. Best of luck hope this helps.

Turbo Saver

I am sure the Turbo Saver has its merits however, you can save a lot of money by just idling your engine for about 20 seconds. If you have driven for hours on the highway (or running it hard for an extended period of time), merely drive it at lower speeds (when getting off the highway) for a minute or so and it will come down on its own.

The best method, however, is to have an EGT gauge. When your gauge indicates a reading of less than 4(400) you then know it is ok to turn the key off.

I also have the IssPro Turbo Temp Monitor (TTM). Works great. I get a lot of strange looks when I walk away from a running truck though. I also watch my EGT's, and driving slow for a few minutes rarely ever lowers egt to the 400 degree range (unless I'm coasting down a long hill). I figure with my stock turbo pushing 28 psi or so at WOT it couldn't hurt to let the thing cool down with oil circulating. If your not scared of some soldering and such, I'd go for the TTM. If ease of install is more important, call up Geno's.

Another Isspro user here. I, too, am very satisfied. A couple things:



1) You need to look at the exhaust temp AFTER the turbo to see if it's cool enough for shut down. You need ot look at it before the turbo to keep from melting pistons if BOMBed significantly, pre turbo is also MUCH faster. Yes, my truck has two exhaust temp sensors.



2) You need to let it cool to 300. After shutdown, the hotter parts of the system may cause the turbo temp to creep up a ways past 300. Oil will start to coke at 370 which is what will eventually kill the turbo.



3) How you drive before shutdown does affect the temp but if you are towing (or modified and not towing) you need to see how hot things really are.

thanks for the responses

are they expensive? i had a friend of mine asking me about them and wasnt sure what to tell him so i used you guys. this site is a great tool i think. anyways thanks for taking the time to answer.

Extreme1 is right about the rest of the system soaking up heat... After a long pull up hill, I pulled over at an overlook. I watched the EGT go down to 300° - 400° and just for the heck of it, I got out the IR spot meter. The exhaust side of the turbo housing was still 550°... So let her cool down!!!



I have a friend that is a fireman and he says that the trucks he drives use a turbo-saver that is basically a small accumulator tank filled with engine oil. It is pressurized by the oil system and upon shut-down, regardless of turbo-temp, it bleeds oil back through the turbo bearings to reduce the chance of cokeing.

Turbo Saver

I have one (Geno's).



It will run the engine 1 minute up to 240 minutes depending on your needs. I use a Practical Solutions High Idler to keep the idle up high if I exceed 5 minutes of idling so I do not have cylinder washdown. Nice to keep the truck cool at short stops while travelling or prevent your souvenirs from melting in a hot cab!



I can take the key with me and the truck will not be driveable as there is a kill switch as part of the unit that will kill the engine if you tap the brake while the key is removed!Be sneaky and put two kill switches in (one obvious and one hidden) and a would-be thief will have a devil of a time trying to hot wire your vehicle!!!!



With the High Idler it makes a great summer/winter combination.



I take my cat for rides with me quite often (Yes, I have a cat who actually enjoys being a passenger! He is not much of a navigator and I have long since learned not to rely on him for directions but that is another story... . ) and he appreciates the cool air in the summer when I do errands around town with him. I just set the thing for 20 minutes, hit the high idle and lock him in! He has yet to try and drive off by himself!



As the kids say today: "It's way cool".
