Evening all

Over in the UK we only really have the option of AMS and Stillen pulley kits. I wont use AMS as the quality is dreadful and Stillen is way overpriced. I dont want to underdrive either

Im only looking for the crank pulley and have seen Z1 do it, anyone running one?

Want to know if its got the seal on the back and wether the balance rubber is on there aswell?

Cheers

PM or give them a call. They are nice to work with and have a great rep.

 

I believe he's looking for unbiased reviews

 

True, but he did ask about specific details of the product. Why not talk to them?

 

Il give them an email, Ive got there breather hose kit on my Z seems good enough. Hopefully the pulley has both things I need on it would be a nice addition to my lightweight flywheel

Does anyone actually run one on their Z? Or do you guys mostly use AMS etc

 

Z1 is great know a couple with them , on my other z i had I had the ams crank pulley and it was perfect !! 80,000miles no issues what so ever just make sure which ever brand you go with make sure its correctly installed lol

 

NST makes kits too and they're popular over on the 370z platform. Pricey, though.

 

I ordered the Z1 pulley during the Black Friday sales and got the more expensive AMS set instead. I haven't gotten around to putting them on yet though.

 

Il be fitting it myself, waiting to hear back from them so hopefully be what im after. Not expecting miracles but believe it will compliment the flywheel nicely

 

i have someone nearby selling his, is it an upgrade worth looking? My car is bone stock but i was looking to get the JWT combo from import parts and this pulley, is it a worthy upgrade??

 

1) no it is not harmonically balanced, the only aftermarket options are ATI or fluidamper.

2)lightweight does essentially nothing except for a little free rev, which is nothing since the car isnt going to move or generate any power in free rev. it needs load to generate power. all the power from pulleys is made from under driving accessorys and even that is only minimal power

3)it does absolutely nothing the 2 or 3 whp people see is entirely within a dynos margin of error and the very next dyno could read 3 whp less then the base line and 6 less then the one after the install. figure this, a flywheel is dropping 15 lbs off a roughly 13 or 14 inch circle and only sees ~8-10 whp. a pulley drops 2-3 pounds off a 6 inch circle, the energy from the weight and centrifugal force to spin that flywheel is easily 60 times greater then that of the pulley due to the weight being further out and much greater. if you want a demonstration sit in a computer chair and have a friend spin you while you hold two 10 lb dumbells straight out, then do the same with your hands and weight held close to your chest. same principle going on. the whole "but my butt dyno says!" is complete BS, there is no such measurement as a "butt dyno" and any felt gains are nothing more then your brain working as the powerful tool it is and you experience the placebo effect, you spent money on something to make you faster, so you believe you are faster and tell yourself it is faster, then your brain forces your body to react as if you are going faster all the while performing exactly the same.
