What are the correct specs for the GSC S1 Evo 8 Cams?

The STI Killer website states:

6008S1------- ADV Duration ------Duration @ 1mm ----------Peak Lift-------------CenterLine
Intake ------------268--------------------- 216 -------------------11.00mm --------------107
Exhaust ----------268 ---------------------220 -------------------10.50mm --------------113

But almost every other place I have check says that the peak lift of the Exhaust GSC S1 Evo 8 Cam is also 10.5 mm.

I swear I have seen the two different specs in different boxes. Is it that the intake with 11mm lift are the newer ones? Was there a revision in spec for GSC S1?

 

I bought my S1 cams when they were first released. My specs are different, so yes, they must have changed slightly over the year and a half they have made them.

My original S1 specs are:

In: 268 10.5mm 107

Ex: 266 10.5mm 113

 

the 11mm intake cam is the new one. we added a little more lift to the intake during the summer of 08. and rather than just releasing another camshaft we revised the S1...

the STikiller website is the current grind and others might be slow to update

Thats what I thought. Thanks for the info!!!

 

sorry to revive an old thread, but how do i know if i have the first batch or the revised set?
the intake's marked jg41 and the ex is lg51.. the prev. owner didnt really specify when they were bought or anything of that sort..
