Who runs a turbo timer?

WITHOUT A TURBO TIMER!
OWEN YOU ARE A GENIUS!!!

it would trigger a relay that sends power to the rad fan, oil fan, gauge and fuel shut off. What a perfect idea.
Where can i find a guage as per what you mentioned? they aren't those like $750 ones that gee-bee uses are they?

again, I would probably not do it as it leaves your car unattended and running for as long as it takes to cool down.

I would probably install the cylinder head probe and gauge and sit in the car watching it, and when the temp got down far enough I would shut down.

that way if something were to happen with the engine temp, oil pressure, etc... I would be there to shut it down before damage was done.

one day, like a young child, i hope to feel comfortable leaving my car by it's self and not worry about it breaking it's self.

Back when I had the turbo I'd idle until the gauge was down to 250F (the lowest it goes) before shutting down. Sometimes I'd turn the ignition back on and watch the EGT gauge start climbing again, definitely heat soaked.

the gauges are like $40 and the sensor should be $20 or so.

the alarm relay allows for lots of control possibilities.

I know my previous comment seemed a little cock sure, I just dont believe they cool that quickly. Does anybody have any real world figures for manifold and turbo temperatures in this situation?

Do all turbo timers work by keeping the engine running? Is anybody using a system that uses a secondary electronic oil pump, and merely continues to circulate the oil after shutdown? This could also be used to build oil pressure before starting.. I would do this if i could be bothered/had the time..

There has to be safety/insurance/legal issues with leaving a running vehicle unattended

rabbitman, how long did this take (drop to 250F) on average? Bare in mind that the gas temps will not properly reflect the manifold and turbo housing temps..

Monkey Magic,

I know that in the praries sometimes when it was brutally cold people would do their shopping if they just needed a few things and leave the car running so it would stay warm. If that car is properly locked and what not I don't see how it would void insurance.
from a theft point of view the steering wheel would still be locked and all the doors locked. from a safety/burn down point of view ... i can see the merit there but do some insurance companies state that if you equip a turbo timer it voids isurance against fire?

Wouldn't the best thing to check be the oil temp in the turbo oil drain line?  Once the oil temp is down to a certain point you know the turbo has cooled off.

I dunno? do you really? you could easily poor cold water into a cast iron pan that's sitting at 100 degrees, then pour it out after about 2-3 seconds and the water wont be much hotter - yes the pan will have cooled significantly.
stop the water from flowing and im sure that water will heat up in a hurry.

[truckinwagen]

that could be done as well in the same way as I stated before, but with an oil temp sender in  the return line.

but I think that a CHT probe on one of the turbo to manifold bolts would give a better reading, as you are directly measuring the temp of the housing itself, not the transferred heat into another medium.

[Smokey Eddy]

Yes Owen that's really an excellent idea. I think i just might try that.

That's probably the BEST option for sure!!
