One thing COMP Cams has never forgotten: Performance is defined by what happens out on the race track. Because no matter what happens on a dyno or in a computer model, if that theoretical performance doesn't translate into real-life results, then the mission isnat completed. COMP Cams spends thousands of hours working with race teams to make sure COMP Cams products provide unmatched performance and reliability. That's why every COMP Cams product offers the highest performance standards. COMP Cams competitive drive culminates at the track and in Victory Lane. COMP Cams has produced more champions than any other camshaft manufacturer.
