Interesting. I like BBK products. It doesn't say the exact underdrive %, but it looks like most 25% UD pullies. I'd like to know how well it's harmonic balancer works also. It's definitely a plus that is has that.
I think they are the same pullies that summit advertises on their brand but I'm not 100% sure. I doubt the harmonic balancer is as good as an ati though.. oh and it def is 25% underdrive and therefore needs a shorter belt.

It slows the accs on the front of the motor down. They rob power at higher rpm. By slowing them down you free up a few hp and prolong their life because they spin slower.
