Is a bigger harmonic balancer better?
No matter what anybody tells you, size does matter when it comes to the harmonic balancer you use on an engine. Putting an incorrectly-sized balancer on an engine will do more than just cause it to not reach its full performance potential … it will cause serious damage to the rotating assembly.
How do I choose a harmonic balancer?
As a rule of thumb, the longer the stroke and greater the torque, the larger the diameter and mass. However, larger dampers can affect the acceleration and revving ability of an engine, so the right diameter and mass can help you strike the right balance.
What is a high performance damper?
Performance Dampers are a new technology that effectively absorb chassis distortion, as well as discomforting noise and vibrations while driving. This revolutionary automobile parts enables high quality, comfortable driving unlike conventional parts.
Is a lightweight crank pulley worth it?
On a well maintained engine with bolt-ons or low amounts of boost like what most owners probably run, a lightweight aluminum crank pulley will not have any life threatening consequences. The engineering reasons are that most modern engines have a short (increasingly strong) crankshaft operating under 8,000 RPM.
How long do harmonic balancers last?
On certain engines, sometimes these last forever, last the life of the engine. And certain engines they might only last 50,000 miles or less than 10 years.
What is the difference between a harmonic balancer and a harmonic damper?
A harmonic balancer (sometimes called crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly.
How much HP do lightweight pulleys add?
10-12 whp
The combination of a lighter weight pulley with reduced engine load generally yields results of 10-12 whp. Just as with a lightweight flywheel, a lightweight or lightweight underdriven set of STILLEN Performance Pulleys will make the car generally feel more lively and responsive and quicker to both gain or drop revs.
Does pulley add horsepower?
Horsepower gains from underdrive pulleys can vary by vehicle, engine, number of accessories and the amount of underdrive (improvements of up to 5–15 HP at the wheels have been seen). Additional and significant performance improvements can be seen by reducing the weight of the pulley versus the original pulley.
Do harmonic balancers add horsepower?
Adding an upgraded harmonic balancer is a great way to keep your engine from having serious issues as horsepower increases. LeBarron goes a little deeper into the issues a stock harmonic balancer will experience as you up the power.
What does a performance harmonic balancer do?
The function of the harmonic balancer is to reduce the amplitude of the torsional vibration peaks to an acceptable level. Most OEM harmonic dampers are not designed to cope with the rpm and BHP levels experienced in competition. That is why racers must consider a high-performance damper that is fit for purpose.
What does a Fluidampr do?
Fluidampr is a torsional vibration damper. Its function is to provide durability by controlling destructive torsional vibration. A side benefit to vibration control is releasing lost torque and horsepower through greater efficiency. The outer housing mounts to the crankshaft.
