What if I get my engine running cooler than factory settings by modifying my cooling fans do I need to turbo time my single turbo engine? becuase certain places I go I do not want to leave my loud car running for 2 min. I can put the cooling fans on timer, the temperature I'm running right now is about less than 160 deg f is that a good temp to shut down after driving?

 

The point of keeping the engine running using the turbo timer isn't to cool down the coolant, it's mostly to give the oil a chance to cool down the turbo bearings so that they aren't hot enough to 'coke' the oil and mess up the bearings.

I think you'll get several opinions on this. Mine is that, unless you're on a track driving hard for several minutes or more you really don't need one. Maybe if you're on a highway driving up a mountain or doing a long high-speed run when you'd have your foot down for a longish period and you wanted to pull off to get gas, I might let it idle for a minute. But normal driving around town and highway cruise, I don't think a timer does anything- the bearing don't get hot enough to harm the oil and cause damage. I'm sure you'll get other opinions that say that's wrong- I don't think anyone has any hard facts.

I do track events pretty often and I just let it idle for 5 min or so after I get off the track- in this case its to let coolant, engine and oil cool down.

 

buy a friggin silencer for your muffler.

 

A turbo timer is simply an accessory. Your turbo just needs a minute or two of off-boost time before you shut it down. Obviously, you can do this by driving at a moderate speed for the last couple of minutes of your trip. The only practical reason for a turbo timer is if you are one of those people who are always in a rush, and you have to get from point A to point B as fast as you can, and jump out of your car so that you are not late for your business meeting, school, etc. Otherwise, a turbo timer is just a toy that looks neat in your car, and has especially little value if your turbo is water cooled.
