Worry not
This was straight 92, not meth. 93 and meth should eclipse this pretty easy.

BUT i'm also running a high flow cat....
I'd like to see 470 on Ivey's dyno.
It's going to be painful getting that close to 500 and not breaking it
I wonder how much i'm giving up from a GSC S2??

me? because I've had them for about a year now and they seemed to be the best option for a stock turboed car. I've said it before: although i have no experience with other cam options, I really really like the S1. They drive great and seem to make great power. 
I'm just worried they're too mild for my new setup. We'll see tomorrow!!

Our customer Thaine has been an avid road racer since he started coming into the shop year before last. His 05 RS has been build deliberately staged so that each time he takes out he can see the differences and if the changes are helping or hurting.
Last year the car on his normal torco/92 mix for the track put out high 320s on the stock cams. A set of S1s yielded a grand total of 366 at 26psi (his max for road racing). This off season, Thaine wanted to mix it up so he added a Red, ID1000s, ported the exhaust manifold, and switched to SD.
With the new found injector I was able to keep the car a little richer for those 20 min lap sessions and to stave off heatsoak induced knock. Here are the results-
and the logs-

This plot shows my car with stock turbo and S1s then with FP-red and S1s. There could be more power to be had but we need to see how this copes with track days 1st

GSC S2 cams were installed in my car before I bought it. The only other mods were intake, TBE, and MBC. I spoke to CBRD because I was wondering if the S2's were overkill for my setup. I was told that they don't even reccomend the S1's simply because they have seen a bigger gain from the S2's even on a stock car.

with the mivec adjustments on the stock cams, we dont see big increases with the s1's... the s2's work excellent..
evo 8 is a different story, s1's show great gains.

This is for CBRD...At what RPM will an EVO 8 start spooling up with S1 and stock turbo? What other boltons if any will help the spool with this set up? How does an HKS 264 or 272 compare in terms of power and spool? thanks guys!
