I was asked a while back about turbo timers on supercharged cars and I really diddnt have an answer..... Do you really need to run a turbo timer on a supercharged car? If so is it for the same reason as a turbocharged car... My thought was by using a turbo timer you allow the turbo to cool down to I believe 300 degrees F. By doing this oil does not sit inside the turbo and In a sense Cook to a gel like material which over time can and almost always does tear the turbo up. Do superchargers get as hot inside as a turbo ( as far as heat by compressing air ) to really need a cooldown timer.. My thought was no but I really dont have a solid answer.


Any Takers?

 

A turbo timer on a supercharger would be pointless, there is no need for one because they never get hot enough to require one. The oil in a turbocharger can actually get hot enough that it can burn up and become ash, this is the reason people use turbo timers. Using synthetic motor oil instead of conventional oil, greatly decreases the chances of that happening. I think that turbo timers are a waste of money unless it is on a race car. You can save money by sitting there in the car with it idling for 30 seconds to a minute which is all that a turbo timer does, it continues to idle after you shut it off for a programable time limit to let the turbo cool down. Then you can use that saved money on mods.[sm=smiley20.gif]

 

Basically what I thought, except the oil turning to ash... Now your talkin hot. Do you know much about diesel engines because im on my first one and in some spots im lost or confused. Not really as much the same as a gasoline motor as I thought. but let me tell you Im really liking it.

 

I know a little about the diesels, but not a whole lot. You don't need to worry to much about the price of diesel going up, because if it goes up much more the trucking in this country will come to a halt.

 

Well I finally got my new turbo timer from APEX installed and it works Great... The only problem is when I first shut the key off the engine keeps running no problem but about 5 to 10 seconds later the engine light came on... the codes were wastegate solenoid malfunction and the other was cooling fan controll malfunction... my guess is that the ecu sees the truck is still running but its not recieving any data from the wastegate or the cooling fan controller.. When I turn the timer off and run the truck a day or so the light goes out. This tells me that there is nothing wrong with either of the two but it is simply that they are not powered on at the time the timer is in use. My question is If I found a way to keep these 2 things powered up while the timer is active, will it solve my problem or create more??

 

Exactly, RR....the owner's manual even gives you the time(s) to let the engine idle for the cool down. Didn't somebody here say that the lubrication system in the SRT-4 had a special design feature that allowed the oil to circulate (it was a fancy scientific word) after the engine was shut off to further prevent the oil from being damaged???[sm=smiley5.gif]

 

I would stick with it and just ignore the light being on, it is only on when you shut the engine off and the timer keeps it running, correct?

 

Yes I do believe that someone on here did say that, but I never did check into it.

 

NO Engine Light on all the time... My concern is that even though I know its working properly and nothing is wrong what if something goes wrong that would trigger an engine light. I will never know unless I periodically check for engine codes which it looks like im going to have to do

 

You might want to contact the makers of the TT and see what they have to say about it.
