In the past, professional race teams have developed custom tensioner solutions to deal with excessive timing belt slack on B and H series Honda race motors. At high RPM, Honda timing belts will flap excessively, to the point where skipping one or more teeth on a cam gear is a definite possibility. This slight shift in cam gear positioning can cause just a simple loss in horsepower but the potential exists for major engine damage if it results in engine valves crashing into the pistons.
Protect your high revving Honda B or H series motor by installing a Vibrant Performance Timing Belt Tensioner. Vibrant Tensioners are CNC machined from T6061 Billet Aluminum, making them lightweight yet very durable. The pulleys feature a special coating to prevent premature wear and tear due to friction from the belt. Completely adjustable (both vertically and horizontally) and easy to install because they bolt up directly to the stock Honda block (requires the removal or relocation of the factory power steering pump).
