MRWOO Posted August 15, 2007 Share Posted August 15, 2007 Has anyone gone to the trouble of fitting one of these, Defender or otherwise? Quote Link to comment Share on other sites More sharing options...
western Posted August 15, 2007 Share Posted August 15, 2007 just let the engine idle for a bit before shutting down to give the turbo chance to slow down with a good oil feed. Quote Link to comment Share on other sites More sharing options...
MRWOO Posted August 15, 2007 Author Share Posted August 15, 2007 just let the engine idle for a bit before shutting down to give the turbo chance to slow down with a good oil feed. Cheer's western I do that anyway, but the added advantage to the timer is it will do it for you for an exact amount of time everytime. The main reason I asked is because I used to have a twin turbo RX-7 with a timer fitted, the timer allowed me to set how many seconds I wanted the engine to idle after I had switched the off the engine at the ignition. The timer would also only kick in the the engine was at a certain temperature. I dont think I'll bother with one as our turbo's are much lower pressure turbo's to that of performnace cars, I'm just curious to know if anyone has done it???

western Posted August 15, 2007 Share Posted August 15, 2007 Just one thing to keep in mind, in the UK, it's illegal to leave a vehicle unattended with it's engine running in a public place except for vehicles that need the engine running to power onboard equipment, i.e. power take off water pumps, hydraulics, wnches. I've seen the timers advertised & while it's a good idea I don't think LR turbo's need them, if they did I'm sure LR would fit from new or offer as a option.

FridgeFreezer Posted August 15, 2007 Share Posted August 15, 2007 I've heard that 200TDi's especially benefit from being idled for a little bit especially after a high-speed run. There must be a simple time-delay relay or such from Maplins or RS that would do it (hell a 555 timer and a transistor would do it), after all it's just got to keep the fuel solenoid open. Whatever you do, I'd stick a "hard" kill switch in there, last thing you want in an accident (EG rollover) is being unable to kill the engine. I'd even go as far as to have to push a button when turning the car off to make it run on. Quote Link to comment Share on other sites More sharing options...
BLACK CAB Posted August 15, 2007 Share Posted August 15, 2007 If I am driving in town with little load or boost I don't worry about it, if its been run at high speed/load on the motorway I let it idle for a minute or two. Its really high out put petrol engines that you need to be careful with, I've had turbine housings on RS Cosworths glow bright cherry red and you would have to let them idle for 5 minutes or more or run them off boost before shutting down. Never used a timer but then I never really left them parked unattended. Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted August 16, 2007 Share Posted August 16, 2007 Fit an EGT gauge and switch off at ~200c then you know that your turbo can't be damaged. Quote Link to comment Share on other sites More sharing options...
Steve H Posted August 17, 2007 Share Posted August 17, 2007 Possibly a slight thread hijack but staying in the same area, the turbo lube kit that Agriemech do, seems to be a small reservoir that filles while driving & empties out when the oil pressure drops. Anyone fitted one?, is this how they work? Plenty of guys have Turbo timers in NZ but I've never considered them essential, wouldn't mind something a bit simpler for SWMBO who tends toward the impatient side & strenuously resists attempts at education. :angry: Steve.

FridgeFreezer Posted August 17, 2007 Share Posted August 17, 2007 It's just a hydraulic accumulator with a 12v solenoid on the end so it releases pressure on switch-off isn't it? Surely if the turbo timer was automatic you wouldn't need to educate the missus, other than making sure she doesn't leave it in gear Quote Link to comment Share on other sites More sharing options...
Litch Posted August 17, 2007 Share Posted August 17, 2007 I always allow the engine to idle for a while before turning off but could never go for an automatic option as firstly I always park it in gear and secondly, the FIA master-switch which I have always used & fitted would kill the engine anyway.

Guest dew110CSW Posted August 17, 2007 Share Posted August 17, 2007 Something I was always told to do with Turbo cars, I always let the OneTen idle for about a minute. Don't need a timer it's easy enough to remember. Quote Link to comment Share on other sites More sharing options...

It's less than the time it'd be off the road with a popped turbo... Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted August 18, 2007 Share Posted August 18, 2007 And very often a minute is not enough to get the temp down. For example, I refuel with the engine running if I have pulled off a motorway. It can take the 300tdi 5 minutes to cool down sometimes.
