Yes, they are.Thank you, I'm intrigued by this innovators west. Are they really that good?
Also what is the significance behind the different crank keyways and like bolt patterns? What's a blow hub for, different offset?
The Romac (for instance) blower balancers have a thicker hub, and come with a larger seal. they are also set up with double keyways, becasue shearing one is not unheard of.
