Default Turbo timer ST setups - 04-30-2019, 09:34 AM

I know it has been discussed in the past but with so many of us going single turbo and most just being only oil feed turbos is a possibility reconsider of doing some kind of hardware update with a turbo timer option/security where it shutdown if goes in gear or something along those lines.
I know factory the water pump stays on but since that wont help at all for the ST turbo guys. Honestly be another cool selling point for JB4! Appreciate any consideration

Car needs to be running for oil to be pumping. If not, you'd want a water cooled turbo for that, but that's for old school journal bearing tech. Not really needed for this stuff. Just let the car sit for a minute if you did some hard driving before shutting off.

I completely understand how it works. Would be really nice to just get up and go and let the car do its thing, with all feature JB4 has it would seem like it would b really easy.

No make it work like any other TT would work, keep the engine running few minutes and shutdown when the timer finishes or the e-brake goes down.

Turbo timers LOL we are no longer in the 90s. We have awesome synthetic oil and modern turbos no longer need them.

Don't put heat into it 60 seconds before shutting it off.....

This is really a very simple concept.

This is like saying you want to cover your car in tires like a tugboat because you keep bumping into stuff. Just stop bumping into stuff.

A water cooled center section doesn't guarantee that you won't get oil coking. It just keeps the max oil temp lower (which doesn't help with shut down times at all) and it cools back down faster. Say 30 seconds instead of 60.

Here's a N54 (water cooled turbos) where the owner clearly liked to do pulls right before shutting the car off.

Turbo smoking from clogged line, now what? - N54Tech.com - International Turbo Racing Discussion


In order of importance

1) Don't flog the car when you know you have to shut it off soon.
2) Keep up with oil change intervals
3) Use synthetic oil

This is completely false. It's still VERY much possible to coke oil. Reference link above.

Actually, it’s 3 minutes for a proper cool down of a turbo. This information is in all the heavy equipment manuals, because there is equipment that runs full throttle for 10+ hrs a day. The engine,hydraulic, and cooling systems take severe loads when running, and every part suffers from the number 1 cause..heat! Without going into an all off topic rumble, every turbo car should at the least, have a two minute cool down to bring the temp down. There’s going to be a lot of opinions about this, the equipment operators know what I’m talking about.

I was being facetious with the 60 seconds. When I did have a turbo timer in a car (previously installed) I think it was set for 90 seconds. But 3 minutes would definitely be preferred if I had just had the engine under load
