I own a 2007 6speed convertible M6. I want to supercharge it but I also want some honest opinion from you guys and if possible some present owners of supercharged upgrades. Which supercharger upgrades are the most dependable? Weigh the cost versus what I will be getting. I would like to hear about potential problems to look for. Anything you guys can add would be appreciated. Please don't come on the thread saying it's pointless to supercharge it because it's already a beast. At this point that's redundant. It's a winless battle because it's getting supercharged. I just want to make an educated decision on which supercharger to purchase.
