richard16v Posted November 13, 2004 Share Posted November 13, 2004 *tongue* hello everyone this is my first post so i hope you can help. im looking for a alluminium flywheel to fit a vauxhall 1.6 16 valve engine in a seven kit. it has a light steel one at the moment , but to go any lighter i need a smaller clutch, and i don't want to do that. any help welcome thanks richard *thumbup* Link to comment Share on other sites More sharing options...
Normans_Ghost Posted November 13, 2004 Share Posted November 13, 2004 Don't think I've ever heard of an ali flywheel in a road car. Get a steel flywheel and twin plate 5.25" cluych unit for best results. However it'a a bit drastic unless your pushing 250+ bhp.The steel flywheel is only there to mount the pressure plate and ring gear.

16vastra Posted November 13, 2004 Share Posted November 13, 2004 fidenza i take it. they have a load of applications, but arent worth the money really. i will have a look in the book when i get back to work monday, but i havent seen a x16xe flywheel. to be honest i would just get a slotted steel flywheel and use a 7.25" clutch, even tho you dont want to, its the way to go! i do 3kg ones for the 20xe, they are quite nice and if you manage to get a 2nd hand clutch setup you will end up paying around the same as the fidenza, but have a much better setup overall.

normalbloke.29 Posted November 13, 2004 Share Posted November 13, 2004 My Caterham has a Fidanza Ali flywheel in it. Ring gear and friction surface is steel. Weighs 3.5KG Standard flywheel was 12KG Engine is 2.0 YB Cos Turbo. When you say "aren't worth the money really", i would be cautious cutting the corner too much on a lightened flywheel, as a failure might cost you more than a rebuild.. It looked so well made i didn't want to fit it but hang it over the mantle...... Link to comment Share on other sites More sharing options...
16vastra Posted November 13, 2004 Share Posted November 13, 2004 they do look lovely, but is it 1 piece alloy? this must inherit stress differences surely with the different materials used the steel slotted flys are at least 1 piece if i am wrong correct me cos i havent actually held a fidanza fly, only seen pics of mates ones Link to comment Share on other sites More sharing options...
DaveK Posted November 13, 2004 Share Posted November 13, 2004 I've got a lightweight steel flywheel on my 2 ltr xe that weighs 1.7 kgs so why the need for an alloy one ? Call ark racing @ penkridge nr stafford and they will make anything for you at any spec. Dave Link to comment Share on other sites More sharing options...
normalbloke.29 Posted November 14, 2004 Share Posted November 14, 2004 Maybe to enable the use of a standard size clutch? Link to comment Share on other sites More sharing options...
Joe 90 Posted November 14, 2004 Share Posted November 14, 2004 If you are using a standard clutch, then you won't save much weight changing from a steel flywheel.

normalbloke.29 Posted November 14, 2004 Share Posted November 14, 2004 Well,if the original flywheel weighed 12kg, and the aluminium one weighed 3.5kg, i make it an 8.5 kg saving. Forgive me if I am being dumb, but the clutch may enable further reductions if you go the smaller route.In my scenario the clutch has nothing to do with the weight savings. I await correction!

Joe 90 Posted November 15, 2004 Share Posted November 15, 2004 Richard says he has a light steel clutch, which may be down in the 5kg bracket (I don't know for sure of course). Bearing in mind an ali flywheel will have a steel clutch face insert and a steel ring gear, the weight saving might be small. As a percentage of the rotational inertia, the benefit might be disappointing. My standard clutch plate weighs 3.85 kg for example. SEP field working, not spotted in 102,900 miles.

henk Posted November 16, 2004 Share Posted November 16, 2004 ali flywheels do not need steel ring gears or steel face plates for the clutch,both faces can be ceramic coated, (flywheel weight 800 grms ,ideal for track, too light for road)regards.

normalbloke.29 Posted November 16, 2004 Share Posted November 16, 2004 It does have a steel ring gear and clutch face insert.It still weighs 3.5 kg with the ring gear and steel face.It is still less than the 12kg standard flywheel.It's still 8.5 kg less than the standard set up.It's still not as light as a smaller clutch/steel wheel set up.But it makes a hell of a difference to my YB Again, if i am missing something I am open to explanation!
