stevemersey Posted February 16, 2012 Share Posted February 16, 2012 While I have my engine out, 1800 Zetec, I am thinking of changing the flywheel for a lighter one. I have not removed and weighed the old fly wheel yet, but at a glance it looks original Ford. The car is for fast road and occasional track days so I am not wanting to go too exotic, so can anyone recommend the best source for a lightened reasonably priced flywheel? The engine is fitted with mostly Raceline parts so they will be my first option unless anyone can make a better suggestion. Link to comment Share on other sites More sharing options...
myothercarsa2cv Posted February 16, 2012 Share Posted February 16, 2012 Burton or Raceline? I'd like to get one for the 7; on the 2CV, I found a later type flywheel which could take a better type of clutch and weighed less than the pre-82 flywheel that I had on my car, and my mechanic shaved a couple of kilos off that making it about 3kg lighter. It made a really noticeable difference - so you could shave the one you already have down. It cost me £50, so much cheaper than a steel flywheel - the weight reductions aren't as great, but if you don't need the lightest it's a good compromise.

Myles Posted February 16, 2012 Share Posted February 16, 2012 Mmm. Time for all of the usual warnings about exploding lightened (as opposed to lightweight) flywheels, methinks! I'm sure a bit of Googling will find some scary examples! Done right (whichever route you take), a lightened flywheel can make a positive change to your driving experience - I bought the R500 one several years back - and after I got used to the greater precision/speed with which I needed to heel'n'toe, it was great!

Phil B Posted February 16, 2012 Share Posted February 16, 2012 Steve, The key decisions on lightened flywheels for the Zetec are driven by what clutch and starter motor you have, or whether you want to change those too. You already have the lightest of the standard flywheels on the 1800. Superlight flywheels tend to use a smaller sintered racing clutch and you need to be wary of ring gear position to ensure the starter engagement is not affected. Both Raceline and Dunnell do cnc machined lighter standard flywheels, as well as billet steel lightweight racing flywheels. Both are reputable sources for this type of part.

stevemersey Posted February 16, 2012 Author Share Posted February 16, 2012 Myles, Yes, by lightened, I meant lightweight, made by someone who knows what they are doing, not modified by me or others. Though I am sure I could make a reaonable job of lightening a flywheel I have no ambition to conduct that experiment, as that circular saw lives too close to my legs. MOCA2CV Thanks, I will check out Burton power. Link to comment Share on other sites More sharing options...
stevemersey Posted February 16, 2012 Author Share Posted February 16, 2012 You already have the lightest of the standard flywheels on the 1800. Phil, Thanks, useful information I did not know. Link to comment Share on other sites More sharing options...
Mankee Posted February 16, 2012 Share Posted February 16, 2012 Could try these guys as well: http://www.ttvracing.com/ They don't deal with the public, but they do sort of, if you know what I mean. Different engine I know, but the K-series R500 flywheels on the Caterham Parts and PTP websites look very similar to the TTV items... Link to comment Share on other sites More sharing options...
stevemersey Posted February 16, 2012 Author Share Posted February 16, 2012 Flywheel now off and weighed and it appears lighter than I expected at 5.5kg including ring gear. Link to comment Share on other sites More sharing options...
myothercarsa2cv Posted February 16, 2012 Share Posted February 16, 2012 Not really sure there's a huge amount of point replacing that... Seems pretty light to me! Link to comment Share on other sites More sharing options...
stevemersey Posted February 16, 2012 Author Share Posted February 16, 2012 Yes, my conclusion too. Put the money towards LSD. Link to comment Share on other sites More sharing options...
zetec Posted February 16, 2012 Share Posted February 16, 2012 it seems too light, ive just gone down th raceline route to make a blacktop zetec fit & weighed both the blacktop 1800 standard & raceline lightened. standard :8.6 kgs raceline:7.4 kgs just flywheels inc ring gear.both silverto & blacktop flywheels seem identical to measure & look at. so i dont think its worth it unless you need to,save your bucks Link to comment Share on other sites More sharing options...
stevemersey Posted February 16, 2012 Author Share Posted February 16, 2012 I think it is this one fitted. here Edited by - stevemersey on 16 Feb 2012 21:20:31 Link to comment Share on other sites More sharing options...
Drumster Posted February 16, 2012 Share Posted February 16, 2012 My Raceline 2.0l Blacktop has their lightened flywheel (5.5kg excl. ring gear). Have a look here and you'll see photos of the the standard flywheel before and after lightening.
