Are lightened flywheels bad?
5 Answers. The main advantage to a lower flywheel mass on race cars is that the reduced mass allows the engine to rev more freely. The overall weight loss to the car is really not the key thing, it’s letting the engine vary RPM really quickly.
What happens if your flywheel is too light?
if the flywheel is too light, it will spin too fast and make your RPMs jump too fast.. therefore, you will not be able to be in the powerband long enough… therefore you need a balance between too light and stock.
What are the cons of a lightweight flywheel?
Cons of Lightweight Flywheels
- Reduced Off-the-Line Performance. If you want to maximize performance from a standing start, a lightweight flywheel might not move you in the right direction.
- Rough Engine Feel. With a lightweight flywheel, the engine will feel rougher while running.
- Gear Rattle.
How does a lighter flywheel affect performance?
Installing a lightweight flywheel doesn’t decrease torque, but it does decrease inertia, meaning more torque will be needed to break traction with a clutch-kick (drifting or burning out), or to accelerate a vehicle off the line during a launch (drag racing, daily driving).
Should I lighten my flywheel?
Beware lightening the flywheel excessively, particularly for road applications, as this can have an adverse effect on tick-over and drivability. A lighter flywheel will improve throttle response and make the vehicle feel livelier on the road as the revs will rise and fall more quickly.
How much difference does a lightened flywheel make?
“We average anywhere from 40 percent to 60 percent lighter than OEM,” Jenkins said. “It does vary per application, depending on whether you’re coming from an OEM single-mass or an OEM dual-mass flywheel.” With a lightweight flywheel, right away you will notice the engine revs more quickly.
Does a lightweight flywheel make noise?
The result is that a conventional lightweight flywheel with solid-hub clutch may create a noticeable amount of rattle. There is simply no cushioning action at all. Note that this gear rattle only occurs at idle, in neutral, with the clutch let out. It is not heard at any other time.
Are heavy flywheels better?
When it comes to choosing the flywheel weight, it is recommended that heavier flywheels are better as compared to lighter ones. Higher the flywheel weight the smoother the operation. A heavy flywheel ensures safe movement by producing more power at a steady rate.
What is the benefit of a lighter flywheel?
The main advantage of a lightweight flywheel is that its reduced moment of inertia, , allows the engine to change its rotational speed, , more quickly. The main advantage of a lightweight flywheel is that its reduced moment of inertia, , allows the engine to change its rotational speed, , more quickly.
Can you modify a flywheel?
The clutch is interchangeable – although there is no need to change the flywheel simultaneously with the clutch, all experts advise you to do this, since both the clutch kit and the flywheel have approximately the same service life.
How much does it cost to replace a flywheel UK?
The average dual mass flywheel replacement cost in the UK is around £750-£1,500….How much does a dual mass flywheel replacement cost in the UK?
| Example: Dual mass flywheel replacement cost – VW T5 | |
|---|---|
| New dual mass flywheel | £520 |
| New clutch | £250 |
| Labour cost | £450 |
| Total cost | £1,220 |
What is a car flywheel?
A flywheel is a heavy disc attached to the end of a rotating shaft that helps smooth out the engine’s power pulses and store energy through rotational momentum.
What are the pros and cons of light flywheels?
A lightweight flywheel means you are going to have to get really good at clutch control really fast. The stock, heavier flywheel (usually 20+ lbs) means you can be pretty liberal with clutch engagement and still not stall. However, the lighter flywheel (sometimes 11 lbs or less!) means as soon as the clutch engages,…
How does lightening the flywheel affect the engine?
Flywheel lightening and its impact on engine performance. “No Fly (wheels) on us.” Lightening the flywheel – the flywheel works in a similar way to the wheel in the toy cars you used to rev up and release and let it zoom off. The heavy wheel located between the engine and the gearbox builds up rotational force with speed and momentum.
Can a light flywheel cause a stall?
However, the lighter flywheel (sometimes 11 lbs or less!) means as soon as the clutch engages, the clutch, driveshaft, rear end, axles, etc that are at a dead stop can overcome the lower angular momentum of the light flywheel, thus causing a stall. The solution, of course, is very easy, you add more throttle while engaging the clutch.
Do you need light flywheels in your car?
If your car is just a daily driver, then I say no. There are probably better, easier, and less expensive ways to make up the performance difference without the added headache of driving with a light flywheel. However, if your car is a racer only, then yes, it’s kind of a no brainer.
