Bought the cams from a member @ HT. When it arrived the markings where shaved off.

Can someone let me know if this numbers are consistent with that of a SK2stg2's

Here are the specs I got from crower this morning when i had it checked.

0.020 ----------------------291.2---------240.0------222.3
0.050 ----------------------257.8---------212.2------193.4
0.100 ----------------------224.9---------179.1------151.4
0.150 ----------------------194.9 --------144.0-------97.9

Peak Lift @ Cam (in.)-----0.308---------0.244-------0.184

Exhaust

http://www.skunk2.com click on the camshaft link and go from there

 

All skunk2 site show is the Advertised duration @ 1mm. I'm looking for the duration @ .050" duration specs.

Crower show both the Advertised Duration and the Duration @ .050" specs.

Does anyone know how to convert .050" specs to the advertised duration?

 

Stage II (Not CARB Exempt, $700-725/pr, retail $849/pr)
INTAKE lift- 12.3 mm, duration 266 @ 1mm
EXHAUST lift - 11.8 mm, duration 262 @ 1mm


Peak lift of .308 = 12.11mm of lift.
Ex. 11.69

.050" = 1.27mm, so 1mm should have slightly longer duration (also 1mm ~.040"), so indeed, it looks like you have some used skunk2 stage IIs w/ some wear on them. Keep in mind that skunk2 has gone through multiple revisions of their cams over the past 10yrs (or however many it has been) and they have slightly different profiles for each....also keep in mind that you could have skunk2 rip offs such as blox or something....

 

Thanks 95 Integra!

I was afraid of this. waiting to hear back from EM1VtecSi on why it was shaved off.

 

Most of the older skunk2s have either "M" and "2" cast into the core (though some oem cams have one or the other as well...I believe the skunk2s were both on the intake and the "M" on the exhaust) and then later they did the etching on the end of the cams (something like ME80IN) and now they cast the little "S2" logo into them. Not sure if that helps any, but hopefully it will.

 

that's the thing it was grinded off
