yea and well the vs aint a bad cam either.
i guess i just get tired of always hearing the xp come up in these topics. what about the nic?? with good tuning that seems like a bad ass cam.
as for stress on the valve train, im not quite postive what causes that but if its lift the xp has more lift than the s1x. i guess im just not a big fan of the zzp cam grinds. whats the fastest zzp cam, the xpz?? thats in the high 11's. ive heard of s1x cams going high 11's. intense cams also have a nice loap. to me it seems like intense has the better grinds compared to zzp hands down.
like said, if it was up the gpf everybody would have an xp. its far from the best cam out there and the vs could probably to just as good as the xp.
vs cam... intercooled s3 heads -- 341hp
xp cam... intercooled s3 heads -- 350hp
there is not that big of a diffrence. IMO the xp cam is not as hot as it is made out to be.
