S stands for street cam. When I was using the s-trim and a stock intake it made 598/531. The intake and T-trim raised my power band not the cams and even though they where designed for less rpm they still did well when pushed to 7k.
A lot of people get good results from the same came NA.
At only 12.5psi with stock heads and intake I made 515/453 I was even runing them with stock valve spings never degreed and I dropped them in with a cam retention tool never removing the timing cover. the 80+ incease was also with the same pulley. Imagine if I did it right lol
Even people with low boost see good results from these cams

They are only 531 lift. Look how flat for a Centrifuge supercharger when I pushed the little S-trim hard.
Stock intake, patriot heads and S-trim @ 16.5 psi. Not my tuners, I did 572 there but is dyno is ancient. I also read lower where I tune than anywhere else.
All the power by 6400 with stock intake and a S-trim

Now the same cams still not degreed TFS intake with oval tb upper, and an Accufab single blade oval TB. S to T-rim same pulley
665/540 @ 20 psi and 7k rpm.

The only regrets I have is that I went with the S instead of the R cam.
Holy crap George, please tell me your car did not go to 12.5:1 afr at 20 psi??? He was letting out of it correct? Are you spraying methanol?
To the OP: the mph cams have made the most hp repeatedly on centrifugal cars like what you have
