I am here to share my small experience on this car and as long as the community is interested, I will be giving my feedback.Hi, newbie here, just learning about these engines, excellent info keep it coming if you don't mind
Is this correct, the "water cooled turbo" doesn't get it's water cooling for like 6.5 minutes after start up? WTF hmy:
Would someone like Evolve be able to rectify these settings do you think? I will, of course, ask them direct when I plan my visit but would appreciate your input.
As Adam pointed out, DO NOT spank the turbo when cold...Generally do not spank any motor when cold...On the Mini the water pump is an on demand unit as well as the oil pump. Oil is also used as cooling means for the pistons and all its internals (oil sprayed pistons) and for the turbo (oil is cooling the shaft bearings). You wouldn't want to put stress on either the engine and the turbo when cold.
Patiently wait for the engine to come into its working temp, while driving it (water,oil at appropriate temp) and then spank it...Remember as soon as it reaches its working temperature the better, so don't idle the engine from cold...(if you do, you are actually adding to the carbon issue as well)
And after a spirited drive, let the turbo and the engine to cool down. Use a higher gear and let the car roll (faster cooling, EGTs drop faster) then wait at idle for some minutes prior shutting off the engine.
Now, I have the EGT gauges and noticed that the EGT's after some spanking drop to 450oC after about 5 minutes at idle. Leave it to idle a little bit...do not rely on the auxiliary water pump (for the turbo) to cool down your turbo cause its like you are asking it to drop from 800-900oC to 400-500oC in a fraction of a second. You can imagine how bad is that for its internals...
I am sure Imran will chime in if he has something to add...
