My car will be a weekend driver, I'll use it for track, and saturdays an sundays at street only. Thanks for the reply. So what do you think would be better? If you where me which one would you buy?

i have the S4's, i love them, the idle is nice and lopey, it takes time getting used to them, you sort of have to change your driving to match your cams. I notice the low end that i've lost, but the upper end is insane.. and i'm still going through stock exhaust and exhaust manifold. if your going all motor i say stick to the S4's
hopefully when i get an exhaust and header i will feel the difference even more
A friend told me, that maybe could be better S3, because I race in 1/8 mile track. But both could be good. thanks for the reply, I think I would go for s4's thanks.
Get slicks instead I only saw a 1-2 tenth drop in ET in the 1/8 with a 1-2mph trap gain with S3 cams. However I dropped 4-6 tenths and added 1mph trap in the 1/8 with slicks.

Go with the c3 cams if money is no object. You'll have to make a hefty purchase in cams/retainers/springs/dyno time but the gains are just about double what the s4 cams produce give or take.
Does anybody have the differences in times in the 1/8 with s3's or s4's??
Thanks a lot.
The difference in power between S3's and S4's is within 1-2 HP, according to the dyno sheets from SCC's Cam Shootout. The major difference being where/when the power comes on. The S3's make most of their power and torque earlier than the S4's.
I might get in trouble making this generalization:
...all things being equal, the S3's would have the advantage in an 1/8 mile run. The S4's would begin to take the advantage as time and speed increases, such as in the 1/4 mile and beyond.
From reading your post and the rest of the thread, I would think S4's or better yet C3's with tuning, as Purist pointed out, would satisfy your needs best.
Either way good luck with your project.
