ok, a long with the 51mm throttle bodies i've been working on (but had lots of uni work to do as well so progress is slower than i thought) I made myself some toothed pulleys sometime last year. seen a few people asking where to get these so thought I could make a few sets in different pulley form.
However. they would be steel (i may be able to get a supplier for aluminium ones but they will be more expensive) and they would need a spacer too, which would be included in the set.
the pulley i run is 2x crank speed but will be able to offer a few others like 1.85x crank speed and maybe a 2.18x if any mad man wants more boost. would anyone be interested in these? if so i could do a few sets.
probs around £150 with a belt, maybe be a tad more or less when it comes round to it.
Ok, well I have got in contact with the manufacturers that made PSD's pulleys. I have asked for a quote for 10 sets of the pulleys and they said they can supply - they would be the same spec as PSD's old ones, hard anodised too. Asked for the phase 1 style anodising because they were stronger. Will have to see what they quote me for before i know prices and such but if people are interested.
It will be good to have these back on the market.
sound good :)
Do you know what kind of aluminium alloy the PSD pulleys are made from ?

no I dont, but the guys who did it for them will know - should have a price next week
Any chance of getting some eaton pulleys made up i can get some dimensions?
Ok, good update today. Visited the place that did the PSD Phase 2 pulleys. They had a set there and I was impressed by them - about 750G in total, maybe 800 with the guides / screws. Would probably have different guides (trying to find a supplier for these atm i think i have one) / screws and they wouldn't have PSD engraved on them (might get G40 on them though;)) other than that they would be identical.
I would want to order about 10 for stock, so not a group buy (unless we can get 10 in for a buy) Price would be £265ish, including guides, assembled and with a belt. Would be able to post to europe too if there was interest.
Now I need your guys help - I need any info on the PSD Phase 2 kit, photo's and such, how much wear? Cause the guys said they did 2 different types. One was a soft ally that was hard anodised, the other was a harder ally that was just anodised. they said the harder ally ones were better than the hard anodised ones.
I know the Phase 1 were done by Pace products so i'm not sure what materials they used, these were good so I have read. Sure some guys on here will know more about them though.
As for the eaton kit, unless there was a good demand then no unfortunately, maybe these would be better for a group buy?
its generally the later silver of hte phase2 i've seen with the most wear

Ok, the ones I've handled were black anodised. I just want to be sure of a quality product to offer people.
the pace products ones are by far the best... I've had a set with about 80k on them and they were mint!
Are the silver ones the phase 1 and the black phase 2?
phase1 have guides on charger and alternator pullies and are browny colour.
phase 2 have a wider charger pulley and only a guide on the alternator pulley. They did a silver batch and a blue/black batch.
Always wondered what the difference was.
It appears I have a set of Phase1 and a set of Phase2 :o ;D
I seem to be the only one who's had the problem(or noticed )it, but the keyway on the alternator pulley of my phase 2 kit was cut same size as the charger pulley when it should have been much smaller. This led to wear on both the alternator shaft and pulley. Had to get the pulley re-cut. Worth checking!
With the eaton pulleys, I'm sure there'd be a need for at least 10. I want 2 (1 for spare charger), my mate would probably want 2 and there's afew people on here after 1.
worth also noting that 'juan' also looked to remake some psd phase 2's which may differ in spec and quality
Ah right, mine are phase 2 but with no guides on them.

Jezz how many miles you done on them? whats the wear like?
Just spoke to Pace Products and they said they wouldn't be able to do them or have any information about the old ones unfortunately.
Quite un sure wether to go for the Hard Ally/ Soft Anodising or the Soft Ally/ Hard Anodising. They did say the hard anodising slowly wore away due to road grime which exposed the softer ally beneath it and wore them. Where as the soft anodising would come off quicker, the harder ally would be stronger long term.
I`m not too sure on the grades of alloy available for them Justin but as i have it the most common grades are T4 & T6.
At a previous work place called Taylor Bends who have Mandrel bending machines and tend to buy T4 as its soft and bends easily.
If they can only source T6 then a trick to bend it without ripping it apart is to rub Imperial Leather soap around the area to be bent
and heat it till the soap turns black. This indicates the correct temp at which point they Quench it and it pretty much becomes T4.
Then it bends without ripping apart.
Therefore i`d say that T6 or higher grade would be best for the pulleys then also hard anodise.
It is also worth mentioning that T4 becomes T6 with age as it age hardens so hence why such as old Alloy mountain bike frames
eventually crack.
I`m sure you know the Grades of Alloy though Justin if your in Engineering and will put me straight if different.
Regards, Fred.
Justin, any updates on this please? :)
