Clutch Test

[rondofj]

Hey guys after weeks of inconsistent power from my R34( as in sometimes you have to really give it some throttle to feel what would otherwise require much less throttle) a couple of times revving out 4th quickly but without acceleration and a few times where the higher gears take long to rev out (boost leak? running rich-sounds groany and much less power) I decided to do a clutch test.

From standstill and in 4th gear and also in 5th gear I am able to slowly move my car forward without any throttle input. Just by releasing the clutch, shudders a bit but then slowly moves forward. Hand-brake off btw. Is this good enough to indicate my clutch is fried? 286rwkw, and - I think its a stock one as I didnt ask what the previous owner put in. Yes I do know the stocker is not meant to go past 200-250rwkw lol.

I also found that I didnt have as much torque goin uphill with a passenger- had to push more on the gas pedal. It is pretty inconsistent though, sometimes feels like a 290rwkw car, sometimes much much less, I do know that I have a boost leak somewhere as well and its running rich sometimes from the sound, bit louder and less smooth and no power. The smoke machine found a small leak we fixed, but still didnt read perfect. Hence its goin on the dyno again, but before that I want to know if my clutch is gone and I need an organic HD clutch - the NPC one for GTT is $786- ouch! Thanks Ron

Hello anyone, is this a confirmation that my clutch is shagged- ie not stalling in 4th and 5th takeoff from standstill but being able to move the car slowly forward with some shudder first before grabbing??

Sit on about 40kmh, put car in 5th, hold your foot down on the loud pedal. If your clutch is gonna slip it will do it now.

Dump 3rd or 4th at limiter from standing start and if smokes from the tyres clutch good if doesnt its gone lol thats my method.

Your car should stall if you are letting the clutch out in 4th or 5th with no revs. If not then your clutch is shagged

Thanks guys already paid for a NPC HD Organic on Thursday, should be here soon, now Im even more sure my clutch is shagged, it bites less easily ( pedal more upwards) and theres a bit of vibration sometimes from idle letting it up
