Turbo Timer?

Turbo Timer?
In the past my 300zx and supras needed turbo Timers to prevent coking in the turbo, do the 997TT Need one as well? Im not one for sitting in the car and letting it idle for a while - Thanks!

Fans would stop the coking - you know when oil gets left in the turbo without running through - it gets sludgy - most turbo cars they say to run it for a minute before you shut it down

Same here. And I don't mind sitting for a minute just listening to the exhaust burble while I wait for the oil pressure gauge to drop down to mid point.
BTW, I have found, more often than not, that if I turn off the engine while the oil pressure is still quite high and leave it for a day or 2, I will get smoke on the next start-up.

I haven't really timed how long it takes for it to fall to the mid-point. But like Bonehead, I drive very slowly the last mile or so (24mph limit in community) so I don't have to spend much time letting the oil pressure drop when I park it.

I haven't done any 'scientific' testing but I can stop at a light and will notice that the oil pressure indicator is pegged on 5 and it's definitely idling.

just let the car idle for a min before you shut down if you did some spirited driving. Once in a while you will get a puff of smoke on start up, not to worry they all do that for this very same reason

Convention current keeps the water moving slowing after shutdown and prevents coking of oil.
This is the reason you do not need a turbo timer on a 997TT.
Hope this answer you question.

The turbos on the 997TT are oil and water cooled unlike the 300ZX and Supra which were oil cooled only.

unless you have a upgraded bigger turbo.
i think porsche's factory design should work perfectly fine.

I can't explain why I would occasionally see the oil pressure higher than mid-point as I drive into the garage. Maybe the drug called Porsche is still messing with what's left of my brain.

I got curious about what I was smoking, er...seeing, so this afternoon I started the car and immediately the oil pressure goes to 5. It seems that it will stay up there until the oil really starts to warm up and then it is pretty much as you stated: down around mid-point at idle.
