I agree with you on the intake. I'll be building one (or three if there is interest) of them this winter, but for 2v turbo stuff.

 

Pretty sure its the OEM that is willing to make cores, but the minimum order seems to be firm at $40k of a given type. I "almost" had a deal worked out for a mixed order 16v and 32v cams for the 928 combined with 944 cores, but they wouldn't allow a mixed order for the minimum production. Cost per cam core was very reasonable, but the numbers totally impractical.

*** The current supply of 944 cores, as I understand it, is running low, which is why 944 cores were part of the deal. $40k of 944 cores lasted something like 8 or 10 years.

Cheap cores would allow all sorts of ideas to be tried, so I haven't given up on finding a source for a smaller run. For now seems to me that reduced base circles and welding are a more practical option than billets at least until we have a few known profiles to shoot for.

 

If someone were serious about 2v stuff, I'd cut the cam box in half so that you could just run bigger lobes than the journals normally would allow.

 

Dennis and Ptuomov,

I am already underway on having new billet cams made. It will be a run of either 25 or 50 sets. I will most likely look at offering 3 levels of cams.
Prices are looking to be around $1200USD, but that is NOT set in stone and could change fast.
I will probably do it as a group buy only 32V and for S4 or S3 heads. And Dennis, you have the right idea when it comes to cam lobes!

If you would be interested in discussing LSA, and other numbers/things you would be looking at please pm or email me. I am going to see him tomorrow morning.

Once more that is for NEW billet cams and these would be cut finished, parkerized, and ready to install and go.

 

I'd be happy to run billet cams w/ plain old lightweight INA VW 35mm diameter lifters. (Thanks to Mike Simard for finding them) It's not necessary to run the keyed lifters. The Subarus you mention have 31mm lifters, no? And they have cams of 272°, 280° & more. There are cams available for VW's using the 35mm lifters that have durations of 280°, 292° & more. The are plenty of grind profiles out there that have the appropriate cam velocities for a 35mm lifter, yet still have durations far longer than stock.


Wow. That's great news! Please keep us informed as you go forward with this.

 

I agree on duration, yes one can grind a billet to have a lot of duration. But it was my (perhaps incorrect) impression that one can grind more duration out of our existing cams without huge problems. But how do you get more lift? My turbo heads would love to spend all their time above 12.5mm lift, and to do that one needs a cam with considerably higher lift than what has so far been seen.

 

That's a damn attractive price. Let's make one of the sets a turbo cam set. I'll PM you.

 

Guys, I have responded to you privately as well but the price I am working on with him seems extremely reasonable for sure!

And I will keep you in the loop regarding the cams.

 

Ok I have recieved tons of interest from my post and I got back from having a meeting and discussing things. There is still some prep work to be done, and it may take a little while till they are ready but I am proceeding with it.

To those wondering the cams I am looking to have made/done will be brand new billet castings.
I will have exclusivity to these cams, the maker will not sell them to anyone but me. The billets will not be being sold as blanks. This is mainly to protect anyone from getting a bad grind/cam and bad word spreading.

These cams will be made so as to be able to run in both S3 AND S4 heads, when we are ready to go forward we will need to know when we start to cut them off.
We are also increasing the contact patch slightly (enough to make a difference) so that those of you wanting to run stiffer springs wont run into wear problems due to increased spring pressures.
The LSA will be 114 deg.

We are still looking at lift and duration numbers. As much as I would like to see a .490" lift with the size of our base circle this is not going to make for long life cams due to the point that would be required. So .460" is probably more realistic. Talking to the cam guy duration between 220-240 @ .050" is realistically what we could get away with. But again some of this is still up in the air.

But there will probably be 3 base options with the option to cut/make almost anything you wanted.
The minimum one will probably be a nice step above the GT with 215 duration @ .050" and lift in the .400" range. Stock GT is 211/200 @ .050" and .393"/.353" lift.

I hope that this answers some questions but I do feel I need to let you know that I am not offering these for sale at this time or even on this board. This is JUST to answer some questions I have been given and get you an idea. When this does happen I will be letting those whom have contacted me privately know first. After that it will be the 928racing list, and finally posting it up on Reutterwerks.

 

If anyone knows what the maximum lift that the stock springs are able to handle is, I would really appreciate them posting that up.

 

Using stock 928 springs or shorter 944 S2 springs and taller lower spring plates? With lighter VW lifters maybe stronger springs are not needed?

 

Stronger springs should not be required for the style of lobe I am hoping to achieve. That was more just a note to those who were interested in running much stiffer springs and increasing the redline.

 

When I bought my 16v cams I am pretty sure the vendor told me to stay away from the ina VW lifters. Do they have any kind of track record in higher lift, higher spring pressure applications?

 

great work colin.....thanks for heading the effort for everyone!!! I look forward to some cams in the future!

 

You should ask Mike Simard, iirc he is running .500" lift with them.
