After some discussions with CDF racing, we will be testing these pulleys on our car over the coming months. They will tested on track and drag environments and put to the test with power up to 600bhp. We will keep the thread updated.

 

will keep an eye out as i might use these for my build.

 

All ready for testing now. There is not a great weight loss but the main purpose is that they are now adjustable , hard anodised & stainless centre's . The are adustable 15 degress advance 15 retard . Not that you would ever need that much .






















Testing next

 

they look great, i hope they perform more than you hope for.

if so iam on the list, this will be my 3rd cdf group buy..lol

 

How exactly would you fit / adjust these?

 

any luck on the testing at the moment ???

 

We received the cam wheels last week and are fitted now with a few finishing touches testing will begin this weekend and will go on over the next several weeks.

Its not good to rush these things

 

lol... just me being impatient

 

still really interested for the rally car as I have ehard that you can get laods of low down power from cam adjustment

 

Don't use stainless bolts, high tensile steel will be stronger, 12.9 cap heads with nice thick washers wouldn't be a bad bet.

 

Yes they look great,how about for my MY99/00?

 

they have them available for 99/00 they just don't realise it.

 

We can't make them yet as we don't have any stock pulleys to copy . They are not exactly the same as 93-97 cams . If they were we could just use those


They are Keyed differently and the cam trigger sensors have a thicker edge , thats the reason we need sample's

 

As above. You already make them, but you just don't know it.

 

Are they excatly the same as the early cams then?

chris

 

It will cost you a set of pulleys to find out!

 

Agree with Paul, i will send you over some 99 pulleys to have a look at.

Also to update the thread the pulleys are now up and running on the car so testing has begun, i will post some pics in the next few days.

 

 

wanna test them on a rally car and really put them through the paces

 

MY99 pulleys = MY01-MY05 pulleys with MY93-97 crank sensor pickups.

I honestly can't believe after all the hints, nobody even bothered to ask me. It's easy, just take an early style outer and fit a new age hub to it, et voila, MY99/00 pulleys. Now just make them lighter and they'll be pretty good.

 

 

Spoke to Neil today and all is well ... few more weeks of testing yet though

 

chris,
iam here still waiting ...lol

 

NOooooo 12.9 grade are very liable to hydrogen embrittlement (google it) and are only safe if kept sealed form water (especially salt water atmosphere like the sea side) 10.9 max.

Fit 12.9 grade and you may as well take a sledgehammer to your engine in 6 months time!

Simon

 

Good point but the issue of hydrogen embrittlement only applies to zinc plated 12.9’s from what I understand.

 

Just to update everyone .


The cams will do on general sale in October, By this time they will have had plenty of testing .

I range we can offer is going to be 93-05 but I will still need to gather some 99 cams - hopefully Neil can let me borrow these ..


They will be offered with Stainless and Titanium centres


The main concern about the adjustable cams in them slipping . I will now add something that will eliminate that . It's a pin system . The pin system will still allow the cams to adjust but when the centre and the body lines up a degrees it will allow you to insert a pin and prevent the body turning/slipping .

Hopefully the below pics will show you what im going on about .. It will also making timing easier ,


I have programmed the drilling of this already .

CENTRE ( STAINLESS PART)


BODY ( ALLOY PART )




Some finished






So what you will have to do is turn the centre to line up with the hole in the body you will know it is exactly a degree

 

looking good chris

will these be available in the 'hard anodised' option just like the other pulleys ?

matt

 

Of course
