Hi mr68gts! I was wondering you are still working on this project! You are doing great work on this Bohr-Hammer hat! Well I just wanted to chime in and ask if you need any help on the injector hat because I am the designer of it! My name is Matt Bohr, I am the CAD designer for Bohr Racing Products that work with Hammer Superchargers in developing this. You did such an awesome job at somehow reverse engineering it I am curious how you did it! I was scrolling though google and was wondering how someone got my CAD files hahaha. Feel free to reach out if you have any questions on actual sizes and dimensions!
