The best turbo timer is you. Wait 5 seconds before turning the engine off. Longer just wastes fuel.

5 seconds? thats all? doesnt seem like a turbo and manifold could cool down in 5 seconds. or are you just saying 5 seconds just to let it spin down?

When I had the turbo installed I waited until the egt gauge pegged at the bottom (250F) before shutting down, a little longer if I'd been running it real hard.
That method only measures the exhaust temp though so the turbo itself is probably really hot still.

if the exhaust coming out was 250*, the turbo probably wasnt that ridiculously hot.

Diesel exhaust is far cooler than g@ssers. 5 seconds is more than enough to make sure its cool and at its lowest speed.

While the gasses may be cooler after 5 seconds, I don't think that's long enough to cool a heat soaked turbo. Its the latent heat from your exhaust manifold & turbine housing that cokes the oil in the journal bearings after you shut down & the oil isn't flowing.
So... buy a house at the bottom of a hill & never buy a turbo'd car from someone who lives at the top of one!

i usually liked to idle my car for around 30 seconds to a minute usually. i never had a EGT gauge, so i figured i might as well be safe and idle it down good.
