Now I know this subject has been covered many times 8-) and I'm not wanting start speculating on what's best, just wondering if there had been any progress on developing an alternative to the double grey setup, as this appears to be the main achilles heel after the the gearbox http://i28.photobucket.com/albums/c248/spe...er1/mini007.jpg

There is the RTS clutch worth a search on here. It's still a DIY job at the moment but people seem to be having good results. "Tuning should be a compromise between what is possible and what is necessary"

Uprated pressure plates are worthless with a midly tuned motor, >130bhp, the RTS is the way to go, people been using this with >200bhp for a good few thousand miles. Audi s4 b5 - 470bhp & 486ft lbs

Depends on the type of engine Gav is building. I get the impression it might rev to 9krpm, and the Verto is a little heavy. I did mention to Fast Carl about an aluminium Verto flywheel and pressure plate. Who know's what might happen On 26th Oct, 2004 TurboDave16v said:

Yeah i've read of a lot of a lot of main faliures because of grey diaphragms. I'm not clued up on the pressure fed thrust mod, whats required? Edited by george91 on 30th May, 2011. |

we havnt had any problems with the good old std issue grey on "pre-verto' light flywheels & steel back-plates, but anything over about 140-150hp we machine the flywheel & make a ring press fit onto the flywheel to move the pivot point for the spring on the flywheel, this way we can get 1200 or 1400lbs of pressure using a Blue,,, yes just using a blue. this keeps peddle pressure down also, but you do loose a small amount of travel. not a problem tho

Looks quite clever that Matt. If something is worth doing, it's worth doing half of. |

well, simply put, the pivot point for the spring is moved outward, a steel ring is machined & the flywheel is machined to have the new ring pressed onto it, & now the spring is instantly produces way way tougher clamp pressure.
