Todays hobby was replacing the crankshaft balancer/pulley on her Mini Cooper S . It was a shitty BMW design and they wanted 400$ for a factory one. I went online and got a billet aftermarket one that weighs less than 1 pound. Now the lil bastard will fly down the road. Gonna save up and get a 15% larger pulley for the supercharger and go eat some Mustang GT's
