Hammer Performance

Before forming HAMMER PERFORMANCE, and even for a year or so after HAMMER PERFORMANCE was formed, "HAMMER Dan" Norlin operated an independent business that performed head porting for other shops, as a vendor to them (never as an employee as implied in the statement at that link above). However, as of spring 2010 HAMMER Dan terminated all sales of h... is head porting and other machine shop services to outside shops. To this day, you can still find dyno results and pictures of head work from HAMMER Dan's head porting process on the web site of a former customer, being used to advertise their own in-house head work. However, HAMMER PERFORMANCE is now the only place this legendary head work is available. Why was HAMMER PERFORMANCE moved from Colorado to Idaho? HAMMER Dan moved HAMMER PERFORMANCE to Idaho to team up again with his long time friend and fellow racer, Aaron Wilson, who is also the original developer of the CNC head porting process HAMMER Dan owns, as well as the developer and manufacturer of the Air Hammer air cleaners, manifolds, and other billet pieces offered through HAMMER PERFORMANCE. Aaron had moved to Idaho some years earlier. Although they've worked together for a number of years on all kinds of projects, since teaming up as HAMMER PERFORMANCE, Dan and Aaron have ratcheted up the R&D, incorporating more technology and innovation into the designs and processes than ever before, to bring you the best products yet. We're proud to say that we're hitting new levels of performance that were not achievable just a few years ago. And we're not sitting still, we're always working on new ideas and products to bring you higher levels of performance with the reliability, longevity, and quality you demand.Read More
