I guess I wasn't thinking of a stock crank. Can you guys supply a key for it for us guys with aftermarket cranks?
It's not news that superchargers are parasitic. I watched one of those shows a while back (forgot which one... it was the garage show, or the guy with the botox smile, or maybe the guy with the handlebar mustache) that had any entire segment with "MR FI" (forgot his name too). He moved to turbos some time ago and now turbo diesels. What was news to me was that superchargers have some hard limit on gas engines with just how much hp you can go. You can't just make the engine and s/c bigger and bigger for more and more hp.
