About Our Company

   Award winning engine builder, Doug Mascaritola, is the owner of Proformance Unlimited. He began his business with the passion and desire to be the best. At the age of thirteen, Doug started working at his family’s machine shop. The school bus would drop him off everyday at 3:30 and he would work until dark. Doug had a lot of fun learning the skills of his trade. Back then, his brother-in-law Eddie called it boot camp. Little did he know it would become his way of life. At Proformance Unlimited they build over three hundred engines a year and pay close attention to detail on each and every engine as if it were their own. Doug and his staff are committed in maintaining their reputation through building the finest engines available worldwide on the market today. Doug wants his customers to know that with his skills and knowledge, Proformance Unlimited designs “Engines with an Attitude” to perform for street and/or track use.
