Why isnt it a good idea with water-cooled turbo's. Don't know much about turbo systems but planning on one soon so any info is appreciated.JohnA said:It's not the best idea for a water-cooled turbo such as the KKK.
It would better suit an old-fashioned Garrett
Looks that wayJohnA said:because the heatosoak peak after engine shutoff is absorbed by the turbo's waterjacket.
You don't need an extended oilflow to cool things down. And it's a good idea to keep idling to a minimum when it comes to plain-bearing turbos.
Aircooled turbos need some very short idling before shutoff, about 30 seconds after they've been boosting. Most of the time you'd be parking during that period, so it would be redundant anyway.
Turbo timers are a relic from the past, and even then they usually did more damage than good. They would be useful if the oilpump were electric, but it isn't.
That's not a turbo timer then mate - that's a matter of a different rad fan.artfulmatt said:But I'm linking the turbo timer to the electric fan !! and never turn the engine off until about 90 degrees !!
