evilscorp Posted October 23, 2013 Posted October 23, 2013 Sorry didn't have a chance to find my old one, will try when I get in from work around 10.30pm to which I will post a picture. Quote
evilscorp Posted October 24, 2013 Posted October 24, 2013 I can confirm the standard pulley has a 2mm thick rubber ring inside it to act as dampening. If you need photos I will upload them later. Quote
Arran Posted October 24, 2013 Author Posted October 24, 2013 Do the ams ones have this rubber ring? Quote
Daryl Posted October 24, 2013 Posted October 24, 2013 Cant say iv had any issues with mine, and i must have done 15k atleast on them. Quote
evilscorp Posted October 24, 2013 Posted October 24, 2013 Me either, but the oem flywheel is dual mass so will act as dampening also I believe. Quote
Arran Posted October 24, 2013 Author Posted October 24, 2013 Ive got a competition clutch single mass lightweight flywheel to go in, if the standard pulley is damped I probably wont get the ams ones if they are not, dont want to risk it Quote
Dblock Posted October 24, 2013 Posted October 24, 2013 Ive got a competition clutch single mass lightweight flywheel to go in, if the standard pulley is damped I probably wont get the ams ones if they are not, dont want to risk it It's your choice but from the reading ive done it wont make a difference. I'm sure z1 uses one on their n/a build. Quote
Mark@Abbey m/s Posted October 24, 2013 Posted October 24, 2013 Stock pulley has some dampening. Yes it does upset engine balance removing the stock front pulley. We Have taken DEs apart that had lightweight crank pulley and have seen noticeably more wear than engine that have stock pulley. It's a big V6 with no timing belt to absorb valve train harmonics. If anything they should be getting proper dampers not no damper. 1 Quote
Arran Posted October 24, 2013 Author Posted October 24, 2013 Looks like their off my list then the flywheel should be enough though I hope. Quote
Arran Posted October 25, 2013 Author Posted October 25, 2013 That's definately damped then isn't it Quote
AliveBoy Posted October 25, 2013 Posted October 25, 2013 That's got as much dampening as a woman reading 50 shades! 2 Quote

KyleR Posted October 25, 2013 Posted October 25, 2013 So, now someone needs to get a list of aftermarket lightened pulleys that are dampened Quote
evilscorp Posted October 25, 2013 Posted October 25, 2013 (edited) Fluidampr and ati are the only two dampened ones I know and I think they are both oversized/not much lighter. (ati may do an oem size but not looked into it.) Expect to pay $300+ for just that one pulley. Edited October 25, 2013 by evilscorp Quote
Lexx Posted October 26, 2013 Posted October 26, 2013 Since this is asking opinions on AMS products.......please do a lot of research on their products before you commit to buying them. They are well known in the Z32 scene for selling defective, or half arsed badly made parts. Many of them are poor copies of other peoples items. Quote

Are they another arm of a well known British based parts dealer who make parts for jap cars? 1 Quote

Arran Posted October 26, 2013 Author Posted October 26, 2013 Think il leave them then, if anyone wants them theres a brand new set on ebay at the moment Quote
Daryl Posted October 27, 2013 Posted October 27, 2013 Im sure the traders on here know what they are selling, and wouldnt sell parts that are substandard. Quote
Lexx Posted October 27, 2013 Posted October 27, 2013 Im sure the traders on here know what they are selling, and wouldnt sell parts that are substandard. Yeah.....because we've NEVER had problems with a trader here have we?....... Quote
Arran Posted October 27, 2013 Author Posted October 27, 2013 Im sure they do know what theyre selling and for the most part they sell great products however after digging in and finding alot of information on AMS I am no longer willing to put these or any lightweight pullies on my car. I understand people havent had any issues but its not a risk I will take. I like to fit the best parts I possibly can on my cars and its a shame I won't fit these but its not worth the potential problems down the line and a few bhp. I find it does pay to dig deep and research a product no matter how small 1 Quote
