vernier pulleys V6 24V

As the title says,Does any of you know if they are available for the V6 24V?
It will save a lot of time adjusting the cams.

Regards,

Tim.

They come as standart tapered cam shafts that lock to pully by means of bolt through the center

if you want after market then i have not seen any but you would be able to get a machine shop to make you a set.

I know they are tapered , I mean aftermarket ones.
when I want to change the cams position to crank (advanse or disadvance) on the dyno with the original cam pully's this means take the manifold and camcovers of adjust then run again if not ok visa versa (lots of work) would be easyer when I can change them from belt side only.

Looked at this myself. AH motorsport do some, but they are dear.

I found one company who took a spare set of mine and they said they could do some, but it was a fortune, basically they wanted me to pay them all set up costs on top of pulley price.

I think a group buy would be worth investigating as its a pain to adjust these, especially with uprated cams

I'd be up for a reasonable priced set if a group buy was set up.

Well been searching myself but cant find anyone, also if you look at the prices for 1 (cheapest is approx €150,-) so that times 2 or 4 and it becomes ridiculous expensive. So I've decided to go and make my own pulleys.

Try and find some prices for a bulk order, I would like to be able to reduce overlap when using forced induction, verniers would make perfect sense.

There's a shop over here that make verniers of a rediculously high finish T O M M I S B I L L E T.

Their standard price seems to be 135 per pulley. They already do a number of different alfa 4 cyl pulleys. If anyone's interested i can check if they are interested in doing busso pulleys too.

I spoke to the guy on charge and he is interested in doing busso pulleys too.

He however wants an initial minimum order of approx 20 pulleys to make doing cads etc economically reasonable.

I've PMd Dan the details, but feel it wouldn't be fair of me to disclose the details of the approximate cost per pulley for a bulk deal. I'd imagine autolusso would give you a nice rebate for being the first confirmed customer of these through them though. If they hit it off with the manufacturer, that is.

Thanks for your PM. I'd only be interested in 1 set for my own car, I think we need to gather more interest to get the ball rolling with this

lol missed that 1st time did you had to bore a tapered hole, the pic from the top is slotted ?
just a thought arnt the Ford RS pullys
No. Teeth/Shape: 40 / circular
Outside Diameter/Width: 119,35mm 30,30mm
would the inside not machine to match the alfa cams, if so they are 140 fo a par by the looks of things?

It's difficult to explain in english...

it will take a little sand so that the pulleys rotate without rubbing, you understand?

Oh, i was of the impression you were asking on behalf of autolusso considering the number of pulleys mentioned and the nice busso builds you do. So i guess i'm not revealing any trade secrets by also sharing what i discussed with the guy with the rest of you.

As i'm currently on iPad i cant be bothered with rewriting all the stuff, so ill just paste in my pm to pud.

He's indeed interested in making Alfa V6 pulleys.

He would like an initial minimum order of approx 20 pulleys to make it economically sane to start fabricating a new design. Price for 20 pulleys would be around 100/pulley, and 40 pulleys would creep down towards 90 a piece. Price a bit depending on what design the center piece should have (which is discussed with the customer for a new product). It doesn't affect the price that the rear and front cylinder bank pulleys have different offset for the center piece, as long as the toothed outer rim is the same for both banks (which it is according to my measurement by eye).

The outer rim can be either light or dark grey (eloxidated?), and the center piece pretty much any color (anodized).

Finished pulley weight is generally around half of the original steel pulley weight.

Taper lock center piece is not a problem.

He wants to know that the cambelt cover doesn't have any parts going into the center of the pulley that might hit the adjustment screws (hope you understand what I mean), and referred to some renault model where this is a problem. That wouldn't be the case for the GTA/GT 3.2 engines as far as I've seen, but I have no clue whether other busso-equipped alfas have different covers where this might be a problem.

He's adding various inscriptions to the pulley center pieces with laser (5/100ths mm deep), and can add for example your logo if you're interested.

To get started he would need a set of pulleys (one front bank pulley, one rear) to take measurements from by laser measurement equipment. I'd imagine you have some spare busso pulleys on the shelf somewhere. He estimates it taking around 2 weeks from him getting the model pulleys to provide a 3D (CAD?) model of how the finished product looks for the customer to approve.

He prefers being paid before taking the process from CAD to production, but does offer a money back or pulley redesign+remanufacturing if the customer is unhappy with the product. I got the impression this is negotiable when dealing with firms instead of with private persons.

Production cycle is a couple of weeks since he uses a third party for the anodizing.

Anodizing can be pretty closely color matched to customer wishes.

I'm very sure I forgot something since we talked for quite a while, but hopefully I got everything important. I believe you're best of contacting him in person so I wont induce some 3rd party translation errors. He should know english since he already deals with US, Norwegian and Swedish companies.

Details:
Tommi Virtanen
Mobile: +358 40 587 1120
Phone: +358 2 2433 663


Will be interesting to see what the finished product looks like if you decide to cooperate around this.

cheers,
Mathias

I really think money could be better spent. I have adjusted mine with dial gauges and when they are adjusted thats it! And you can lighten the originals too. And spend 400 or more pounds for other tuning parts.
