michel lane Posted November 21, 2002 Share Posted November 21, 2002 Can anyone tell me if this this fact or fiction, I was told today after enquiring about fitting my new clutch (havent ordered it yet), that the standard UK spec Flywheel will not be able to cope with anything more then 500 lbs of torgue through it because its to thin ???? and what they suggested was to change it for a different fly wheel. This is from a toyota garage after i enquired about fitting charges of a new clutch , the clutch being the Twin plate TRD one. Now is this true ???? would appriciate all the help Iam intending to get to about 600lbs of torque throught the new clutch , with the hybrid turbo upgrade and other stuff...

Alex Posted November 21, 2002 Share Posted November 21, 2002 600lb/ft from Hybrids!!! ..... Anyway. Sometimes you need to get the flywheel skimmed or replaced...but there isn't a different version that you NEED. RPS Stage 3 Sprung hub clutch with a Mueller solid flywheel would be a worthwhile upgrade... Quote Link to comment Share on other sites More sharing options...

eyefi Posted November 21, 2002 Share Posted November 21, 2002 ive read that some of the americans r using the stock fly with after market clutches and running around 700whp. i cant comment on the validity of it tho. one of the guys on supraforums is gathering data on crank walk, which seems to have happened to a few us sups. he's gathering clutch, fly, oil info. it seems a little early to say yet but it may b linked to some clutch and fly combos.

The stock flywheel is internally damped to help crank and gearbox life. The damping element has a finite life, and I am now replacing flywheels on a regular basis, they give a characteristic rattling sound that people often mistake for gearbox noise. They are probably capable of handlinng the torque, certainly not too thin, but drag starts, if that's your thing, generate massive amounts of heat and the effect of this on the damper is unknown to me, but probably very detrimental. You won't get 600 ft lbs of torque from the mods you cite, anyway :-) Seriously modded engines should really have a one piece chrome moly steel flywheel fitted. I think JUN list one. There will be more noise and a reduced transmission and crank life with these, but they are more suited to a radically modded engine and drive train.

michel lane Posted November 21, 2002 Author Share Posted November 21, 2002 i think the 600lbs of torque was a bit off an over estimate at the moment , but i would like to be prepared in the future ... thats for your comments in helping me understand this .... the dealers are all a pack of lying w*nk*rs...... a bit to harsh words at the moment.....

Ugh - is this rattling noise really noticable when you stop the engine? If so - how difficult is it to replace, how much would it cost, and as someone who is only intending hybrids and does very little drag racing is a stock item a better bet than an uprated one? Mine's pretty baaaad... Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 25, 2002 Share Posted November 25, 2002 Keith, yes, this rattle is often first heard at idle and switch off. I haven't had one fail altogether, but have now fitted about 5 flywheels because of this. I'd say stay with a stock unit, engine life may be compromised by a one piece flywheel and noise almost certainly will increase without the damper. I think a new flywheel is about 170 quid, very cheap for what it consists of, IMO. Quote Link to comment Share on other sites More sharing options...
Keith C Posted November 25, 2002 Share Posted November 25, 2002 Cheers Chris - as I said when we spoke earlier, I have no doubt I'll be paying you a trip soon enough... Quote Link to comment Share on other sites More sharing options...
