Xtreme HorsePower is a business owned and run by and Father, Son, and Uncle team. They build engines for race cars and other semi fast four wheeled vehicles. Whether you have a dirt track car, or a three second funny car, these guys have the time, money, machines, and devotion it takes to build a fast motor. They are a bit pricey, but thats expected with the kind of work they do. I have been in this shop, and let me tell you, if I wanted a motor built for a race car, these would be the guys I'd go to.
