Installed the Vortech and quickly needed a clutch that will hold boost. Many people write about JWT but I could not find any G35 videos.


Pro's: Smooth grab, very springy feel, not difficult to hold down for long periods of time, very close to oem feel and grab. Its much easier than the OEM I had. (after taking old clutch off there was plenty of material but they said my pressure plate may have been defective from the start)
Flywheel is very smooth, I think the revs have less vibration than before. Rev matching is very easy now, just a quick blip.

Con's: The girlfriend commented on the "chatter" or "cement mixer" "diesel engine" type sound at idle when the car is at operating temperature. It goes away if you press the clutch in.



Clutch has about 75-100 miles on it, no drag launches. It was worth it small sacrifice because now the car pulls so hard its SCARY!!

Thank you for the great installation Larry and Eli at Project X and ChicagoZ.com !


So tonight i QUICK made a video showing the chatter for anyone considering this mod....

ya thats pretty much what mine sounds like too. have you noticed the chatter under acceleration at low rpm?

 

yes when i am in too high of a gear for my speed, or too lazy to down shift. probably jjust part of the territory i give up for quick revs

 

alright thats EXACTLY what mine does too. glad to see its not just my car and that its common. thanks for the help and video.

 

I ended up ordering the JWT clutch/flywheel combo. Thanks for the video since I now have a real-world example of the "cement truck" sound people talk about. Doesn't seem too bad and the cost/performance savings are well worth.
