what is the torque spec on the bolt anyway? I am about to do the install tomorrow, any info would be appreciated...

 

The specs from UR say to 1st torque the bolt down to 29-36 ft lbs. then mark on the pulley where one of the lines is on the bolt. Then tighten the bolt until the next line on the bolt matches up with the link on the pulley. It's pretty damned tight by that point!

Z1 PM me with an install price please...

 

after my install I had the belt squek during cold starts. I went ahead and tighten the belts and now the squeks are gone. I do however hear something new during accelerations. It almost sounds like a turbo spooling up but not nearly as loud. Could this be sound resonating from the pulley? I don't think its from a loose belt because I retighten them. People that have the pulley can you try to drive with your windows down to see if you have this sound. Its almost like a very faint whistle or spooling of a turbo sound. Sounds nothing like a loose belt, weird.

 

Hmmm... I'll have to listen and see.

 

the crank pulley is $100 to install

 

Mine are backordered =(

 

I got mine today from Concept Z Performance. Total cost was $230.00 shipped (pulley & belts)

Here are some pics...







Driving Impression:

It revs ALOT quicker than before! seems like the power just never ends!! I have no problem with belt squeeling, etc.. Idle rpm is about the same, and the voltage gauge is about the same as before..I will recheck the belt after one week. Overall, I think this is one of the bang for your buck upgrade!

Thanks!

 

OK.... Thats it!! After reading all of these reviews I must say.. I can't resist the temptation. This is going to be my next mod for my Z. It seems like most people are definitely satisfied with it and for the price you can't go wrong. If someone knows where I can get the best price for this please let me know. Thanks in advance.

 

I would definitely recommend these pulleys to everyone! Even though they are a pain to install... the end result MORE than makes up for the sore arms and scraped knuckles.

It's supposed to take up to 7 days for the ECU to recalibrate itself to the lighter weight of the pulley so I haven't really been "trying" to notice any difference.... but it's no use, I do feel a difference for sure. I DEFINITELY feel that the car pulls better from 3500 up. Down low I have to admit that it feels about the same. But the Kinetix Cats and Plenum next week will help that out I hope!

I wish my pullies would go and not be backordered =(

 

OK guys it's been one week since my original install and I must say I have never been on the gas this much. Darn it my gas milege has gone down because I can't stop speeding . This pulley makes my car feel like a totally different animal. Sometimes when i step on the gas from a stop I get my neck snapped back because I'm still not use to the new found power. THANK GOD for this mod!!!

I guess this thread is why we had a rush on Silver Crank Pulleys'...

If you ordered them they are coming in this morning and will be shipped out today...

The 3 pulleys look great... but... the Crank Pulley is the one that makes the power...

I cant wait to put the crank pulley on my car, because with the super light flywheel I have it will probably exadurate the effect of the pulley...

We have some Colored Belts and Colored Hose's which I will be putting on the web site shortly.

 

Colored belts and hoses?!

DADDY LIKES!!!!

Does this mean I get a bonus for starting this thread?
