Z1 twinplate .....(No flywheel problems ^^) actual brand is "competition clutch" rated 700ft/lb torque (conservatively) only 22.65 lbs for flywheel and clutch there is an extreme hat and disc which holds more 820ft/lb Basically the higher clamping force single pressure plates not only use more force to clamp the clutch disc to the flywheel but also put more force on the crank / thrust bearing when disengaging the clutch. The more force applied to the thrust bearing the more wear. Once it wears past a certain point the crank will move back and forth inside the engine eventually destroying everything. Z1 clutch does not use as high of clampiing force because of the design which is the benefit to using multi disc clutches not to mention the reduction in weight and lowered rotational inertia because of the smaller diameter of the entire assembly. .
RPS twinplate carbon-carbon http://www.z1motorsports.com/product_info.php?cPath=6_385&products_id=106 Expensive but I'd highly recommend it if you want to win drag races. You go rocketing of the line like you wouldn't believe. Is a real pain to drive when you don't want to go rocketing of the line (i.e. most of the time).
I think getting the clutch properly adjusted also is critical . I noticed on mine it slipped at the top end of boost before I adjusted clutch . Still not 100% I think it may need another bleed .
Hey Rob Does this apply to most single plate clutches? At the moment I'm running an Exedy HD 5 Puk button clutch quite happy with it - relatively easy to drive. Is there an actual ft/lb amount where it is to high e.g 750+? Not sure what mine is hoping it isn't something that could possibly cause a problem down the track. Matt.
Can't give you a rating as to what clamping force on a single becomes a potential Problem but one like rob260's when trying to hold big power and flexing flywheels means time for a twin plate.
I've read this on Z1 website, it was coupled with an ad for their twin plate. Any examples of this actually happening? Where it can be shown that premature wear on the thrust bearing had occurred? And they must be suggesting the thrust bearing wears on the front or the rear if we're suggesting it leads to crack shaft play... I have a hard time seeing how this could occur prior to other serviceable parts wearing.
No thanks it means time for decent flywheel. Problem solved and beautiful to drive. Pedal feel would be lighter with a twin plate but engagement would be much harsher. Ill happily trade a heavy pedal for being able to take off smoothly and quietly. If I was to go twin plate it works be exedy D series with damper or get NPC to build something similar. Give the driveline some relief.
When you feel my engagement you'll change your mind .So streetable..And You can't even here the rattle. Try before you knock it
the reason i ask is that im in the middle of my build and to balance the bottom end they want the flywheel and pressure plate, price is a major factor at this point in time im looking for 400 - 500Hp at the wheels so i dont want over kill nor do i want a crap engagement.
