Hey i've got an 08 m8 with an aerocharger running 8 to 10 pounds of boost just curious what anyone else is running for clutching i ride about 9000 plus elevation an what rpm's your running. I've been running stock spring in secondary with a 36/46 helix and a d and d maroon spring in primary with d and d adjustable weights last trip i finally got the sled running good but only had about 72 grams weight in clutch and pulled 7900 rpms but had it loaded on heel i've been reading now turbos like tip weight wondering what anyone knows thanks.
