I have a 540 also with VF engineering supercharger, I had plenty of cooling problems! These cars build to much pressure so I'm using Evans waterless coolant! I could drive my car all day lift up the hood & remove the radiator cap while the car is still on, no pressure! I also went OEM with the temp switch, aftermarket doesn't work well! I had one that keeps the fans at full blast! Can't even order at a drive thru, lol!
@@A1Brian 100 extra HP, 100 extra tork! I paid 5k 7yrs ago, it's 6k+ now. Definitely a difference, my car is at M5 stats now but you'll end up wanting more after awhile! Not sure what to do now!
I crashed mine 1 month ago :( ☹ I feel even depressed I bought a 2004 530i 6 speed manual But I miss my v8 sound so much I'm trying to sell it or fix it to be honest I don't know what should I do just need the radiator, fan blade and headlights
