Wormhole

Please let me know if you have a good one.
Thanks

Lemming

I may have a good one from a 968. I know one cam lost a tooth, but think that was on the intake side. I can check tonight when I get home. I'll shoot you a pm later.

I have one but it has some pitting on the lobes, so unless you're going to have it reground I doubt it will be of much use.

Wormhole

Great, thanks Tim.

Yea, looking for one in good shape.

Anyone know for certain if the camshafts from a 944S2 and 968 are identical?

Lemming

PET shows different part numbers

S2 944 105 275 09
968 944 105 275 10

Careful here ; the number of teeth on 968 is different than in S2.

I have A-class condition camshafts but they are herer (in europe)

But, you can use 944S exhaust cam ; that'll give you little power-hike too.

Wormhole

I plan on using a twin cam gear setup so I'm not really concerned about the number of teeth.
However, I would like to know the profiles for each.
How is the profile in the 944S cam different that it will net more power?
This will be a turbo application so everything will be different, but I'm still interested..

There is a 3 degree difference between when the exhaust valves open and close.

Wormhole

Thanks. That is 3 degrees opening later?
Thats between the 944S and the 944S2, correct?
Is the duration and lift the same?

Lemming

John,

I do have a good 968 exhaust cam, PM me if interested.

krazykarl

Exhaust opens 36 degrees before BDC on the S cam and 39 degrees before BDC on the S2 cam. Exhaust closes 4 degrees before TDC and the S cam and 7 degrees before TDC on the S2 cam. I'm getting this info from the workshop manual, not sure about duration and lift.
