    Crank Pulleys with integrated trigger wheel adapter

    I designed and had machined a crank pulley for the common block that utilizes the water pump and Alt. Its about a 15% reduction in size over stock. I am currently working on one that is the same size that keeps AC and PS. I posted on FB and had some interest but I always for get alot of people on here are not on there. Here is a pic of the current pulleys I have made and then a sketch up of what the new pulley will look like to retain the AC and PS.

    Alt Waterpump Pulley is about a half a lb lighter than the regular aluminum underdrive with the added adapter.

    New pulley will be about 1 ounce heavier but is also about 10 percent larger.

    Very nice. I'm interested in one. Glad you posted here as I'm not on FB. I've only got one common block car, and looking to update it to Microsquirt type system. I don't have a need for the A/C pulley. Forgive my ignorance, but does it trigger off the front of the pulley, or are you bolting the wheel to the front of this?

    That's pretty awesome. I am also interested in one.

    Any chance for a non-common block variant?
