CPR provides Romac High Performance Engine Balancers in two configurations.
Romac Lightweight Balancers have a Steel Hub/Steel Outer Ring. The steel construction of the outer ring allows the balancer to react more fully to crankshaft torsional loads.
Romac Ultra Light Balancers have a Steel Hub/Aluminum Outer Ring. The aluminum construction of the outer ring allows the ultra light balancer to react more quickly to crankshaft twisting, making the Romac Ultra Light Balancer perfect for high RPM, quick-reving applications.
Available in both configurations, Romac Blower Balancers are specially designed for blown applications. They are manufactured with a .125" larger hub to protect against the violent torsional loads exhibited by roots style superchargers. They also feature dual keyways, placed 180 degrees apart and include the requisite timing cover seal.
Romac Dampers are manufactured with an Elastomer band offering increased reaction to the extreme torsional loads created in today's high output racing engines. This design is infinitely superior to clutch or fluid designs that are designed to handle harmonics instead of the twisting of the crankshaft when the full weight of your car lands on the crankshaft. This is especially true in "Power Adder" applications where crankshafts suffer from extreme distortion due to heavily increased engine loads.
Romac Dampers are manufactured with a CNC machined steel hub and an steel outer ring. They are the safest dampener offered, as the external balance weights are integral to the steel hub, making it absolutely impossible for the weights to come off the dampener. The aluminum outer ring overlaps the hub and is retained by a .125 thick retainer ring, completing the best engine dampener currently available.
Romac Dampers are dimensionally correct for ease of installation, guaranteeing minimal hassle in aligning pulleys and drive belts. Also the outer ring has 360º timing marks for your convenience.
Romac Dampers are S.F.I. approved.
