Kyosho Regular Location: Wollongong Registered: November 2004	Re: BOV's Wed, 05 January 2005 10:42 Norbie wrote on Wed, 05 January 2005 21:06 Firstly, a turbo will "spool down" pretty much instantly when you take your foot off the throttle, so a turbo timer has nothing to do with that. Idling down a turbo engine is beneficial in some circumstances, ie if you shut the engine off when the turbo is glowing orange you're going to cause long-term damage! Of course this will very rarely (if ever) happen on a street car, which is why I believe turbo timers are a total wank. FWIW all turbocharged piston-engined aircraft have a minimum idle-down period after landing (usually around 5 minutes), so the issue is real. Of course aircraft engines experience vastly different load cycling to automotive engines, so this doesn't mean the same thing applies to a car! I'd have to disagree with the "instant" spool down... We could still here a cars turbo we were working on for around 30-45seconds afterwards spinning down... It was a T28, and the engine was not being boosted, we had it sitting there idling whilst working a tune on the idle... Yet we shut the car down, and you could here the turbo spooling down (Whining), but yes they do start to spool down when you first take your foot off, but they don't instantly "stop" when you turn the car off...
