This happens apparently. Another boosted K RC member was saying recently, he'd had the same problem. The pressure plate needs more clamp pressure, take the pressure plate off and send it off for a spring upgrade.

My STD clutch held 100rwkw/134rwhp with huge amounts of torque. But if I slightly rested my foot on the clutch pedal it would slip, so I'm guessing that was pretty close to it's limit.

ahh i see well ill have a look at that, my other plan was to put an old supercar clutch in it and use 1 plate instead of 3 plates and machine it down

yeah your right taz the plate seems to be a bit small. maybe i can try an extreme or something

Thought about switching up to a T50? I couldn't imagine a k40/50 will last you too long at all.. Especially if you have a weldy(?)

where would i find a bellhousing and is the clutch used with that any better then the one i would have?

are you using a 180mm or 200mm clutch? i HIGHLY doubt a button clutch would slip with boosted 4k. ours didnt slip with a highly boosted 7k?

 

derpp?

or put in a tricked trimatic....

Aforementioned clutch held up perfectly, Copped a reasonable amount of crap on top of the 250hp it was taking in the first place. Never slipped.

yeah fly machined its whatever size the stock 4k flywheel is havnt measured it. its on e85 and has lots of torque at about 130hp it starts to slip must be where its making the most torque i guess. also its adjusted correctly if anyone was wondering

What do you mean? I was just assuming there'd be more/ better options for clutches for the t50. Never actually looked into it with mine
