[zlobo]

Hi!

a frind of mine bougt an s2 some weak ago. he was told that the car has s1 cams, he was realy happy about that.
But i think it's not s1 cams.
I wonder if any one can help me to determin what of kind of cams it is?

The data on the cams is:

inlet cam have folowing numbers on it:
281B 054 mon4 and it's lifting 9,5mm 210degres@1mm lift

exhaust cam have folowing numbers on it:
7049 054 102 w20 04 4 and it's lifting 10,1mm 218degres@1mm lift


Does anyone know what kind of cams this is?

Im unable right now to check the numbers of S1 cams but there is a major difference between S1 and S2 cams as you can see on the attached picture. S1 cams has a cogwheel while S2 uses a chain between the cams resulting in S1 rotating against eachother while S2 cams rotates in the same direction.

i know that but i am thinking about the cam profile?
This is a dalbäck tuned car so i think its only 7a cams in it, and not as he was told.
