Stock 6speed clutch ok for bpu?

Recommended Posts

Hi I've just got a 6speed box but might need to buy a new clutch and was wondering if any one has experience of using the 6speed stock clutch with bpu and if it's ok? I currently have no plans to go single so really don't need anything that handles over 400bhp plus I would prefer a stock clutch feel:cool:

 

Any advice will be appreciated

Thanks

Odd! Mine started to slip after about 400-500 miles. Might have been worn ...

 

In fact, in fact thinking about it now bud. When Jurgen brought mine over, he said the clutch was slipping so replaced it with an uprated one, no idea what it was though?? so that might had something to do with it lasting alot longer. It did however feel bloody great, well compared to the southbend one i have now.

Available now: Uprated MKIV TT clutches.

 

 

I use a stock, brand new driven plate, as it is correctly

balanced, doesn't judder and will hold all but big torque

highly modded engines or cars used for drag racing.

I modify a stock brand new cover to give more clamping force.

The reason I tooled up to do these is some of the aftermarket

US clutches I have fitted SEEM to be built from used cover

assemblies with reground friction surfaces, and a stronger

spring. I have had hellish trouble getting these to fully

release, because due to this seemingly thinner cast iron

friction face, the geometry of the clutch goes to pot, and

being a pull type clutch (the hydraulics pull the bearing

away from the engine, rather than the more normal push type)

it is a lot harder to effect a cure.

 

For 455 pounds plus VAT , you get a brand new driven

plate, a brand new modded cover, and a brand new release

bearing. I would rather fit myself so any complaints are down

to me, I see a lot of clutches damaged by people without the right gear

(a ramp and transmission jack, plus correct circlip tools and fitment)

or clutches fitted to patently *uggered flywheels. I will do a supply

only if you feel competent to tackle the job or are using a bona fide garage to

fit the clutch

 

 

Toyota use a dual mass flywheel (the flywheel is in 2 parts, an inner and

outer assembly, damped in the middle) which is now showing signs

of wear causing a lot of rattle when idling or on very light

throttle openings. For God knows what reason they are charging

about £400 + VAT for a new one, they look more like they should be

over 500 to me, but don't say anything :-) The very similar LUK dual

mass flywheel on Maseratis is nearly £1000 + VAT.... So if the flywheels

old enough or abused enough to be scored it should be replaced.

 

Fitting by myself will cost £175 + VAT.
