foxdie Posted July 22, 2004 Share Posted July 22, 2004 Pretty new to Turbo's etc, just wondered how long i should be letting the timer carry on for? Any other tips too? Link to comment Share on other sites More sharing options...
Rob84 Posted July 22, 2004 Share Posted July 22, 2004 my mate with the 200Sx (who was at RR day), he's got a Greddy TT, and that plugs into his ECU and it calculates how long the engine should carry on running for by calculating how hard its been driven Link to comment Share on other sites More sharing options...
foxdie Posted July 22, 2004 Author Share Posted July 22, 2004 mines not that complicated, goes up to 9 mins. Usually after a fairly hard drive let cool down for about 6mins. If haven't been running boost then i'll just let go for 2mins. That about right? Link to comment Share on other sites More sharing options...
Rob84 Posted July 22, 2004 Share Posted July 22, 2004 yeah, seems fine that method. also, if u've had a hard drive, then a easy one, like driving off the motorway through town or whatever, then the timer doesnt need to run for that long also i think the most critical thing with turbo's, as u most proberbly know, is to let them warm up sufficiently b4 reaching full boost Link to comment Share on other sites More sharing options...

Rob84 Posted July 22, 2004 Share Posted July 22, 2004 run it on Optimax too, as thats the closest stuff to Jap spec petrol, which, its obviously set up for Link to comment Share on other sites More sharing options...
foxdie Posted July 22, 2004 Author Share Posted July 22, 2004 been using BP ultimate, as my nearest shell garage is about 1/4 tank away lol Certainly drinks petrol, only £39 to fill it up to the brim from the warning light. Down 48 mils and used just over quater of a tank, and i've been driving it really slowly! Link to comment Share on other sites More sharing options...

mk1dub Posted July 22, 2004 Share Posted July 22, 2004 Personally I wouldn't let a Turbo'd car cool down at a stationary, idle state. First off, you wont be getting air through the radiator to aid cooling (coolant cools the oil, along with an oil cooler - if fitted). When stationary the heat from the turbo cannot dissipate effectively, even though the fan(s) are on, the outside ambient air temperature is going to be much cooler than that of the current engine temp. I would suggest when you are a couple of minutes from home to drive the car off boost and to allow a sufficient amount of air to pass through the radiator. could be a load of tosh, just my opinion.. I know it's not what you asked but something to bare in mind anyway. (Trackdays are certainly a different matter......) Link to comment Share on other sites More sharing options...
JonC Posted July 22, 2004 Share Posted July 22, 2004 any car non turbo or turbo should be given a cooling down drive after a thrashing it allows the engine / oil / radiator / brake discs and clutch to cool downi usually allow about a mile of driving at the speed limit to give the car a nice wind down Link to comment Share on other sites More sharing options...
AutomodellistaGT Posted July 22, 2004 Share Posted July 22, 2004 not a perticular scientific answer but you should let the fan kick in and then turn it off once the fan stops. i almost allways let the rust bucket idle for about 5 mins, but shes older and not as reliable as a toyota Link to comment Share on other sites More sharing options...

(Trackdays are certainly a different matter......) the reason you let a turbo car cool down standing is cus if you stop the engine as soon as you stop driving. The oil pump stops pumping and all the oil sinks to the sump, while the turbo is still spinning. This can cause damage to the bearings or whatever. Also it still majour cools down a turbo just sitting. They get silly silly hot. Link to comment Share on other sites More sharing options...
