warm up

do you hav to let the supra warm up in the mornins b4 drvin it?or can you just turn the key and go?

Use your common sense and dont thrash it from cold. Stay below about 4000RPM until the temp gauge has started to move.

Hi

been discussed before - conscensus is its always wise to warm a turbo'd engine; whether its necessary or not is unclear

tech bods kma lol

It's wise not to thrash it when cold, but not to just leave it idling for 10 minutes before you drive it anywhere.

i don't think there's any need to let it stand still idling for ten minutes, just don't thrash it (i.e. stay under 4000rpm as Digsy said)

i cant afford to leave it for 10mins,

i just pootle around on low revs, until the temp gauge is resting at halfway

Agreed, never have time in the mornings either!

Note that the temp needle is taken from the coolant. In terms of engine damage, it's the oil temp that needs to be warmed up. This may take longer than the coolant.

IMO even if you do warm up for a few minutes, still a good idea to take it easy for a few miles as the oil in gearbox and the diff will still be cold and need to circulate

Owners handbook says to let it warm up for two minutes if you're legally allowed in your country (e.g. in Germany you can't).

Having discussed it on here before, I tend to give it 30 seconds while I pick a CD and put my seat belt on, then drive as off-boost as possible.

The car doesn't drop out of fast-idle mode until it's had a stationary two minutes or so though, and will still be in fast-idle after a 50 mile motorway trip.

I have wondered if there is anything bad about this, for example is the car running a richer mixture? I'm sure not though, it's probably just holding the idle throttle position open more.
