Also, I use my Corvette for spirited driving so my use of the turbos in BMW is only when I need the power, not just for the fun of it. That also keeps the heat down and I'm sure that prolongs the life the rubber/plastic on top of the engine.

WWC careful doing this ….. that cover is there to stop intense heat soak to the bonnet , or hood for you yanks hahah, that could eventually damage the paint finish. I’ve asked a number of BMW people about this over the years and they all said leave it in place for this specific reason. The plastic clips break on mine all the time around the small coolant reservoir for the charge coolers and this drives me crazy. I get why you would do it but assume like me you don’t track your 650 so really it’s probably not that necessary.
