blandy 29 Posted July 25, 2017 What is the "limit" to the mi16 clutch? I'm building a 2.1 at present so aiming for around 230bhp and 180lbft kind of area. My car sees no road use as is purely a track toy. would the mi16 clutch be up to this still? Share this post Link to post Share on other sites
welshpug 1,621 Posted July 26, 2017 my standard gti6 clutch seems to be coping fine on my 2.2 Share this post Link to post Share on other sites
Tom Fenton 1,524 Posted July 26, 2017 I run 210 ftlb torque through a standard Mi16 clutch, make sure the flywheel surface is flat, no issues. Share this post Link to post Share on other sites
xy8 4 Posted July 26, 2017 (edited) I had problems recently with Mi16 clutch (LUK), but it´s my fault , messed up downshifting too many times. Springs that hold pressure plate in place failed , at first there was vibration , clutch still worked , but then some loose part hit crank sensor and race was over. Engine, mi16 head, iron block with dw12 crank , not sure about hp and torque. Edited July 26, 2017 by xy8 Share this post Link to post Share on other sites
dcc 855 Posted July 26, 2017 96x86 race engine? Nice how does it rev? Share this post Link to post Share on other sites

petert 549 Posted July 26, 2017 It's not the torque but RPM that kills Mi16/GTi6 clutches. All those little springs just want to jump out and the straps, whilst fine when driven and in tension, were never designed to go backwards on a big downshift. Share this post Link to post Share on other sites
blandy 29 Posted July 26, 2017 That's my main concern. I've no doubt a mi16 clutch would be ok for road use etc but mine will be purely used for track work. I've not long fitted a brand new Valeo unit so maybe just have to try that as already bought and paid for etc but didn't know if it would be common practise to go for a updated unit Share this post Link to post Share on other sites
welshpug 1,621 Posted July 26, 2017 if its still hydraulic tappets you wont be revving it too much past what the standard gti6 goes to. Share this post Link to post Share on other sites
xy8 4 Posted July 27, 2017 To be honest it was not new pressure plate that failed , I used it couple of years on different engines . It looked and worked ok when I bolted it to dw12 crank , but yes it was used part so that and lack of driving skill plus bigger engine destroyed it. I installed another mi16 clutch , it´s valeo this time and try not to miss accelerator pedal on dowshifts. Share this post Link to post Share on other sites
blandy 29 Posted July 27, 2017 Yes will still be in in hydraulics so not massive revs Share this post Link to post Share on other sites
Tom Fenton 1,524 Posted July 28, 2017 I've used a standard MI16 clutch for trackdays for 8 odd years without a problem. Revving to 7200rpm. Personally I will use the most cost effective option until it causes me an issue and proves the need for something better. Share this post Link to post Share on other sites
dcc 855 Posted July 28, 2017 As above, my mi16 clutch used to be fine at 7800 rpm without ever causing an issue Share this post Link to post Share on other sites
SweetBadger 91 Posted July 28, 2017 (edited) Mi16 engine revved to 7800rpm, did about 15 track days, 40k miles and a whole race season on a standard MI clutch, no problems. Gti6 race engine (lot more power 8000rpm), started killing mi clutches after about 20mins on circuit. I put this down to a combination of a solid rear engine mount, and an accelerator pedal height that made it very difficult to heel-toe (= the odd unavoidable big downshift). I'd fit a standard MI clutch and see how you get on - try to be easy on the drivetrain on downshifts when on track. See here if you want a clutch that will definitely do the trick and put up with race/track driving (not cheap though) http://forum.205gtidrivers.com/index.php?showtopic=168781&hl= Edited July 28, 2017 by SweetBadger Share this post Link to post Share on other sites
blandy 29 Posted July 28, 2017 What power is your gti6? Think I'll give the mi16 a try then just have to work on technique a little Share this post Link to post Share on other sites
SweetBadger 91 Posted July 29, 2017 The graph is attached: 194 @ hubs, approx 220 flywheel Share this post Link to post Share on other sites
blandy 29 Posted July 29, 2017 So similar to what I'm looking for then Share this post Link to post Share on other sites
