GMballistic Posted June 10, 2014 Share Posted June 10, 2014 Yeah I would stick to just the pulleys, I looked at importing belts previously and it was more expensive than the UK Can you get hold of the correct Gates belt for this pulley set up then Chris? Would prefer to get it all from you of course if possible. Quote Link to comment Share on other sites More sharing options...

Up to you, but you just will get exactly same belt but for £60 instead of £20ish lol We already configured out sizes for it anyway 1 Quote Link to comment Share on other sites More sharing options...

Not the £60. Do you know where to get them then Vlad? Quote Link to comment Share on other sites More sharing options...
GMballistic Posted June 10, 2014 Share Posted June 10, 2014 Belt wise, as far as I remember - each step smaller pulley shortens belt by 0.5"... So if you going from 3.33" standard pulley to 3.12", you'll need 0.5" shorter belt... That's as far as I remember! Please double check From what I've read the standard belt is a 93.5" 6 rib ~ so for the 3.12" pulley you would need a 93" 6 rib belt. Gates make them from what I've just read on my350z.com. Ok so doing more research this may be the wrong lengths. Reason being Vortech have changed the belt arrangement (less pulleys or something) so the belts now will be shorter from what I'm lead to believe. Might just have to wait and see what belt comes with the Vortech and take 0.5" off it when looking for a belt. The belt part number Tarmac listed converts to a Gates belt number K060795 from what I can ascertain. Which is apparently an 80.070" belt.!? Getting confused now.

Vlad Posted June 10, 2014 Share Posted June 10, 2014 You can get them off eBay. I usually get it from local car parts place (GSF or Leamoco) They just normal 6 rib belts...so not hard to get it Quote Link to comment Share on other sites More sharing options...
Tarmac@TarmacSportz Posted June 10, 2014 Author Share Posted June 10, 2014 I think Vortech get the belts from Europe so they will be going to USA to then come back to Europe, thats why they are pricey at Vortech Quote Link to comment Share on other sites More sharing options...

The belt part number Tarmac listed converts to a Gates belt number K060795 from what I can ascertain. Which is apparently an 80.070" belt.!? Getting confused now. Well, yes, either wait and see what you will receive or as you said it's got part number and it says 80.070" - just get 0.5" shorter...but you need to transfer it from inches to mm... So 80.070" = 2034mm Then minus 0.5" So 79.5" = 2020mm So, you will need 6PK2020 belt http://www.ebay.co.uk/itm/310826609954 Simples Belts need to be pretty tight to stop spinning and loosing boost... So you can get one smaller belt(to be on safer side), I think next one down is 6PK2013 (2013mm in length)... You can always just return it and get refund if you don't need it Quote Link to comment Share on other sites More sharing options...

The belt I listed though should be the length we need though as I converted Tarmacs part number to it. So we should need an 80.070" belt to run the 3.12" pulley. The standard belt I would imagine is 80.570" odd. I think? Quote Link to comment Share on other sites More sharing options...
jumping350 Posted June 10, 2014 Share Posted June 10, 2014 which belt do we need then Quote Link to comment Share on other sites More sharing options...
Vlad Posted June 10, 2014 Share Posted June 10, 2014 Oh ok... Then for 3.12" pulley you will need 80.070" belt...closest one is 6PK2030 You can get it from same eBay link I've posted above! But I would suggest to go to your local parts store and get 2-3 belts... Like 2030, 2020, 2013 etc...then see which one fits better and return others (usually you have 28 days to return) - that makes it easier than posting item back to eBay seller for a refund. Or just wait for confirmation from Chris, ones he gets it from vortech...or just wait and see what belt you will get when SC comes and then go to the shop Quote Link to comment Share on other sites More sharing options...
GMballistic Posted June 10, 2014 Share Posted June 10, 2014 which belt do we need then Ok this is how I see it ~ Tarmac/Chris posted this as the belt we need to run the 3.12" pulley on the V3sci; Serp Belt - 2A046-795 - £60.00 That converts to a Gates belt number K060795 according to google when you put it in the search. http://www.vortechsuperchargers.com/product_variation.php?pvk=2101 Which from what I can find is an 80.070" 6 rib belt. http://www.oreillyauto.com/site/c/detail/GAT9/K060795/03306.oap?year=2012&make=Ram&model=2500&vi=1502367&ck=Search_C0074_1502367_-1&pt=C0074&ppt=C0007 80.070" in millimetres converts to 2033.778. So using Vlads eBay link the closest is a 2033mm belt which is Gates part number 6PK2033 on the link; http://www.ebay.co.uk/itm/310826609954?var=610227490327&ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Not sure about going smaller?? the next size down is 2030mm which is only 3mm different so could be ok I just have no idea how much adjustment is available and whether this is beneficial or even needed?? If Vortech say to use a 80.070" (2033.778mm) belt then I would imagine that's correct. @Chris/Tarmac ~ what's your opinion please? Quote Link to comment Share on other sites More sharing options...
Vlad Posted June 10, 2014 Share Posted June 10, 2014 There's quite a bit of adjustment so me personally would go for 2030 belt 1 Quote Link to comment Share on other sites More sharing options...

GMballistic Posted June 10, 2014 Share Posted June 10, 2014 There's quite a bit of adjustment so me personally would go for 2030 belt Think I might do what you mentioned when we where chatting ~ buy three belts from a local supplier, check their returns policy first ..and then buy a 2033, 2030 and 2020. Then just return the two belts I don't use. Although it's expense at first which I don't like, it may be the smartest idea. Quote Link to comment Share on other sites More sharing options...

The Chubby Ninja Posted June 11, 2014 Share Posted June 11, 2014 Don't worry about the cog belt, it's the little belt behind the charger. I think they come with them in the kit Quote Link to comment Share on other sites More sharing options...
mouthwash Posted June 11, 2014 Share Posted June 11, 2014 Description: The Vortech 3.12 pulley for your Vortech supercharger system on the 2003-05 Nissan 350Z or Infiniti G35 with non-Rev up motor is an efficient way to increase power levels by increasing the speed of the supercharger and increasing boost. Vortech pulleys are made from 6061 aluminum and hard anodized in black. The surface is CNC machined for excellent belt fitment. A 79.5" belt must be used with this pulley. It is offered as an option if you do not already have this length. Vortech supercharger systems use a centrifugal design that has been a proven performer for decades. Each vehicle-specific kit is designed with the best fitment in mind while providing impressive power gains, even on otherwise factory vehicles. Injected Performance is an authorized retailer and installer for all Vortech systems. 1 Quote Link to comment Share on other sites More sharing options...

So that would mean a 2020mm belt to possibly be a little too long so next inline on the eBay Gates belt link would be a 2013mm. A difference of 7mm so I would assume there is enough adjustment for this.

mouthwash Posted June 11, 2014 Share Posted June 11, 2014 According to our American friends and I've read this a few times.. Also, to answer my own question, this pulley requires a 79.5" belt kit (according to Injected Performance's website) which is Part #V2A046-795. Looking at the parts list for the V3 SC, it comes with that exact belt kit, so seems good to go I don't think it's that clear cut though, that's the problem: http://my350z.com/forum/forced-induction/562249-vortech-serp-belt-swap-3-33-to-3-12-pulley.html you drop 1/2" in belt size for each 1/4" decrease in pulley size in the end its easiest to buy 3 or 4 belts around that size, use the one that is the tightest and return the rest. Haha, someone just do this before me and tell me what belt they used! Quote Link to comment Share on other sites More sharing options...
