These ultra lightweight flywheels have the ring gear cut into the main body.
Whilst the alloy ring gear does have a limited lifespan over the steel versions, we have found them to be better than expected, especially when used on low compression turbo engines, due to less effort needed to turn the engine over.
Other things to ensure a good working life are making sure the engine is a good starter, there is nothing worse than a badly setup motor that refuses to fire into life until it has been cranked over for 5 minutes.
We have successfully used this setup in our 16 valve turbo car for the last 2 years, and have only just replaced it with an identical item as a result of a foreign body damaging two of the teeth. Without this it would still be in use.
If and when the alloy teeth wear badly, they can simply be machined off and a new steel ring gear fitted, thus giving a new lease of life.
Contrary to popular myth, there is no reason why these flywheel setups cannot offer years of service when taking into account the total cost of running a competition car.
To show how confident we are as to its useability, anyone who buys one and uses it in their competition car, and is not happy with its wear rate at any time within the first year, we will fit a steel ring gear FOC.
