For people asking for specs the cosi have more effective duration @1mm than the S2. In fact, I was beating around between the cosi's and S2. Here are the specs. Cosi's effective duration @1mm is 255 IN & 221 EX with 11.0 lift for both, S2 is 230 IN & 225 EX with 11.2 lift on IN and 11.0 EX. With that being said the cosi have 25degrees more on the IN than the S2.

So they work on the butt dyno but no numbers? I know the cosworths did not have a good showing at the dyno day i went to. My first pass untuned made more power then they did after the tune. Im not saying the S1's are better, im saying i like them and they seem to be making good power all over the board.
I think some people forget that you arent on the peak hp rpm ALL THE TIME. Theres a a whole lot of room to gain if your setup is right. And cosi or s1's doesnt matter if your set up is right they will work out. Both are good cam selections but the decesion i had to make was more bottom end and midrange with a little more top end or more top end than anything and i choose the s1s because they suposedly made the most power across the board not the most peak hp.
and for what its worth S1's FTMFW, greg at gsc has been on top the customer service game since the get go and to me thats worth a few hp.
Oh and for the guys with the Cosi's in the 9's, hows the idle. Ive heard they lope really hard and ive heard they idle like stock?
