Lightened flywheels

I think [MENTION=58]Raptor6767[/MENTION] is in the process of making one also, not sure if its too sell or just to test though.

For now just for my car and when it's done will test it out on my car.

Then if it's light and cheap enough I might offer them.

The goal is <3.9kg and <£400.
 
Just fitted one from engine dynamics. Weighed it before fitting and it came in at 4.3kg. I then weighed the original flywheel It weighed 6.3kg! Will let you all know how I'm getting on after it has been bedded in along with my brakes.

I would say that if you wanted a lighter one then I have. Then you would have to look at getting one custom milled.
My flywheel has made a notable difference when on a trackday. Down shifts seems to be easier when going down the gears into corners.
I read somewhere that having a lightened flywheel affects your torque would like to see if that is true or not.
 
Did u felt that torque is affected? I read that lighter flywheel will reduce inertia force and make the car struggle at higher speed? Any reviews?
 
Honestly, I see all this "May affect torque crap" all the time...

Scientifically and logically, when you look at it, the engine is only going to do what it can do. Think of lightened parts as the equivalent as putting a ball bearing turbo on a car, it's going to boost earlier because of the extra weight spinning and aiding the car. In an N/A car though, a lightened part is going to get up the revs easier and you're going to get in to your power band faster, there are no other variables. How in gods name does a lightened part REDUCE torque? It may reduce torque when you come off the throttle and back on as the weighted part is going to want to spin for longer, but how in gods name will that increase your torque either?

What you're trading off as torque for engine free speed you are NOT going to notice a power difference. You won't go faster, but you'll certainly get there faster. Besides, if you're going to lighten a component, the loss in torque, if I'm incorrect (because I know nothing) will not matter, because you'll need less torque in the first place because the car weighs less overall.
@R27SG Very rarely you are going to be doing 130MPH on a track mate, to be honest.

If I've totally missed the point, can someone more mechanically minded explain. Logically, I just can't see how it would make a difference. What's traded off, will be picked up elsewhere.

Although lightening any component is a MUST. Remove your back seats from your Clio and the ISOFIX bar which will come in around 22-30kg weight loss and you'll actually notice a difference.
 
Can anybody with a lightened flywheel give us a proper before and after feedback please? All good with the theories but what we miss in here is some real life feedback.

From what I know (in theory again) is that the car revs faster, however the revs drop faster as well for the very same reason. Less mass less inertia. How faster do they drop though? That would also give an enhanced negative effect when driving on uphills as the effect is magnified. Now that might not be a problem for the vast majority of people but for me plays a significant role as I'm doing the Alps every year and the car struggles as it is already!

Also the fuel efficiency is probably negatively affected as well as you'd now need more energy to maintain a certain speed on the motorway, again less inertia so more energy needed to maintain a specific speed.

I really want to fit one of these flywheels, I really do, especially now that I'm dropping my box. However I haven't found any solid information about it which makes me believe that people are trying to justify their purchase by either lightly praising them or by not giving any input at all.

Again, I would massively appreciate any feedback from people who made this mod either on the Clio or on a different car.
 
I've just ordered a 3.5 kilo super light flywheel from ttv to suit a 184mm clutch.
Once it's all fitted and back running again I'll let you know how it is. A quaife ATB diff is getting fitted as well.
 
You don't need to that's all smoke and mirrors I would rather have a diff that works than one that doesn't The synchros will go before the diff wears out lol

I did half think of a gripper diff, but all the talk of pre loads was a bit intimidating, dunno how its set or anything.
Are you saying the Atb is no good then?
