We can save you money, time and heartache by building your next motor that will do what YOU want the FIRST time. 

We don't build cookie cutter engines to compete with online prices.  It is important for our customers to be satisfied with their next engine build. 

As a racer myself, I understand how hard customers have to work to come up with the hard earned cash and we don't want to waste it!

With our attention to detail and one on one personal attention, "dyno" expertise we have the confidence that if we can't make it run better than what you had - you don't pay.  We want you to get every ounce of power you paid for.
