I used to leave mine idling for a few minutes. Invest in a turbo timer though
good point, and set it to run for how long?
Id set it for 3 or 4 minutes
really that long, even if its only running 380bhp?
You will probably have to cool down too so if you are booting it around and then get home or to where you are parking, you should let the turbo cool down a bit before turning off the car, this will avoid the turbine sticking.
