Agno Posted February 22, 2018 Posted February 22, 2018 For the uninitiated, can someone please explain the supposed benefits of the BMW unit over the standard item? OdinZ 1 Quote
d3c0y Posted February 22, 2018 Posted February 22, 2018 Not 40 years old. I pulled the stock one off my L24 and found a massive crack coming from the key way. cracker 1 Quote
luvemfast Posted February 22, 2018 Posted February 22, 2018 (edited) BMW pulleys are thinner and larger diameter. The biggest advantage is that the rubber bond is not on the diameter, but on the face. Old racers would cross the finish line at full noise and back off. The sudden RPM change rip the bond clean off. With the BMW balancer, this failure stopped happening. They need some modification to fit. Has the one for sale been done to be a bolt on? Edited February 22, 2018 by luvemfast Quote
280zUSA Posted February 23, 2018 Author Posted February 23, 2018 Hey mate, Not sure if it has been modified to fit! Cheers David Quote
