do you know what a turbo timer does ? if you dont ill tell you why.

 

what does a turbo timer do?

 

This is what i know, a turbo spins at over 90,000 rpm. Not to mention the fact that 1,300 degree exhaust is blowing over the exhaust turbine. If you turn off your car after running it hard, oil can turn solid from the heat around the turbocharger. You have to idle your car for a few minutes to let the oil circulate and cool down the turbo. People usually dont do this or dont want to wait. A turbo timer wires in to the ignition to keep the car running for a few minutes (user-defined or automatically calculated) to allow the turbo to properly cool down.

 

I don't understand how oil would turn solid after being hot, if you raise the temp on any substance, having it turn solid is usually the least of your worries. Maybe I'm just reading this wrong.

 

so you answered your own question on why it would take you five more minutes to pump your gas. cause the turbo timer keeps your engine runnning the five extra minutes.

 

the oil doesnt exactly turn solid. it gets "coked" up. yes thats exactly how corky bell describes it and he authored the so called "turbo bible".

basically means it gets gritty and causes premature turbine bearing failure.

there is a graph of temp vs oil stability but i dont have a scanner. ill try to get it up here but i forget things daily soooo.

well id rather wait an extra 5 mins than blow myself up.

 

i think his point was more referenced towards engine health, not time spent pumping gas.

the point is you get off the highway while racing around and pull up at the pump, your turbo is still red hot from highway spooling and you cant just turn your car off and start fueling because that would be bad for the turbo bearings...
the car MUST idle for at least 1-2 minutes to cool the turbine bearing jacket off with colder engine oil

get it?

Got it.
