It was installed by the dealer... first time I drove it felt the difference in TR (the car feels more smooth)... after I drive it a couple of hour I start to drive it hard... the clutch slip in 2nd 3rd and 4th... I begin to think they was something wrong... I just keep driving hard for another 50 miles and the car slip less everytime, in the nigth I race w my bro and the car slip just a little and with that I saw difference since I step on it on 1st gear to top end... today the car feels more normal and I'm sure this mod help the engine all the way, 1st gear to top end... the car feels that need it all alone!

P.S. someone expirience this slip thing... how much to break-in if any?

 

You should not be having any clutch slip.

 

There has been an issue lately with JWT Flywheels bolts backing off. make sure your dealership used loctite when tightening them!

 

My flywheel did not come with bolts, aside from the bolt that distinguishes between Z and G35/Maxima. I used the stock bolts. Are there different bolts?

 

Thats what I meant

 

Is all in place they use the bolt that distinguishes between Z and Maxima, they used the stock bolts. the car feel better know but I was assuming that it came w some plastic cover or something but everything looks good!

what are the torque for the bolts of the flywheel... mine are 50 TQ I think!


Anybody knows why my clutch slip???

 

Thanks for the comments... the clutch stop sliping and feels very strong... like I said this is a good mod.

 

webcar, have you went to the track lately.If I'm not mistaken you have ran a 13.5 or 13.6 in the past.

 

not that lucky lately... the hotter wather and rain is a ***** in here can't make good times... I will let you know!

 

Maybe there was some grease left on it or something?

 

I am assuming that the OE clutch was reused so, it may be possible that the OE clutch disk was unevenly worn to match the OE flywheel so, with the new flywheel the disc is not is full contact yet. This may cause the disc to slip until it re-seats itself. Did the installer suggest a new clutch? I would have done it just to ensure that it seats properly...

 

I think you theory is rigth, because the car feels great now!

Thanks for the replys

 

Webcar, does your flywheel make the chatter or grinding sound? I heard that they will chatter if its not balanced properly with the clutch and if that you need a sprung hub clutch to balance it. Do you know if that is true?

 

Well in the begining there was NO grinding sound and now you can hear it sometimes! everybody else have the sound... I know they install it very carefully step by step but I'm not sure they use a sprung hub clutch to balance it, I assume they did!

hope this help!
