Flywheels are like money in the bank; you can't take out what your haven't put in! A flywheel is essentially a storage device. On larger displacement engines, lighter flywheels (10-14 lbs.) tend to work well mostly because they are easier on the long stroke cranks. Less stress is introduced to the end of the crank when less mass needs to be "brought up to speed." In stock classes a heavier wheel (18-22 lbs.

Horsepower to the flywheel is usually what you see manufacturers stating about their cars. This means an engine without the transmission, wheels, etc.. is strapped to an engine dyno and the flywheel horsepower is measured. In the case of a 2000 Honda Civic Si, the motor is a D16Y8. The motor is rated at 127HP. This is the horsepower rating at the flywheel.

At the flywheel horsepower is always higher than the wheel horsepower. When the power is being transferred from the engine to the wheels, so of the power gets wasted in the drivetrain moving parts, such as the transmission and differentials. So, the wheel horsepower is the power that actually made it to the wheels. Remember, AWD cars have a higher horsepower loss in the drivetrain than the FWD or RWD car.

Although some manufacturers claim a specific horsepower increase, superchargers actually add horsepower as a percentage gain (percentage of an atmosphere). Assuming an engine with a compression ratio of around 9:1 running pump gas,if a supercharger gives your engine 14.7 psi of boost (another atmosphere) that will essentially double the output of your engine, everything else being equal.

There are many methods to removing an engine flywheel. The easiest method that will not damage the engine's piston is the "hydro lock" or "hydraulic" method. With the engine out off the chassis, glow plug install and the exhaust header removed, turn the engine upside-down. Use a non-silicone after run oil to fill the cylinder. Turn the flywheel until the piston compresses the after run oil against the top of the cylinder.

Horsepower is a measure of an engine's work-producing ability, combining both an engine's twisting force and its ability to rev.

We have not performed any test, however, you will feel a noticeable power difference, especially when you accelerate at around 50-75 mph. More air is forced into the intake at a higher rate of speed and then generates the horsepower gain you will receive, especially in colder weather. The high flow filter will produce a more high performance sound from your vehicle's engine.

only if you don't mind the noise. every mkiv with a lightweight flywheel will exhibit transmission rattle with the clutch out. this is noisiest on hot days where the tranny is warm and the a/c is on. it's only noticeable when engine braking, idling and accelerating at low rpms. make no mistake, it can get VERY loud.

This is a very good idea as the engine will rev much easier. Take it to a professional though as they will be able to advise on how much to lighten it by. Too much and not only will you weaken the flywheel but the engine will not idle very well. Getting to the flywheel requires the removal of the gearbox which is a time consuming task. Therefore it only makes economic sense to lighten the flywheel at the same time as the clutch is being replaced.

Most of the two and four person motorcars commonly operated on our excursions have a 20 horsepower Onan 4 cycle engine. Some restored older motorcars use the original 2 cycle 5 horsepower engine. Since we travel at low speeds, more power is not required or even desirable.

Nextel Cup “open”, or non-restrictor plate engines, run over 800-horsepower and Busch Series open engines run at over 700-horse power.

A.The flywheel should be resurfaced when the clutch disc is replaced. This process provides a machined surface for the clutch disc and eliminates any "runout", extending the clutch life. All 5 Winchester Auto Stores have a complete machined flywheel inventory. You can purchased them on exchange basis saving time and money.

The term horsepower came from Scottish inventor James Watt. The value for a unit of horsepower was determined after Watt performed several experiments on horses pulling coal. He originally determined that the average horse was able to pull 22,000 foot-pounds every one minute. In other words, a horsepower was defined as the amount of power exerted to move 22,000 pounds of coal by one foot in one minute.

Just quickly, we have managed to coax an almost stock S/T up to 102bhp (rear wheel) at 8900rpm. It is still fitted with stock mufflers, though it has a Dynojet kit fitted, and a slighlty modified airbox. We have discovered there are two types of Dynojet kit (early and late?). The "early" one can be distinguished by a double diameter needle, while the "later" type is a conventional needle. From our tests, the early type seems to give better bottom/midrange, the later better top end.
