Any idea with the GS C S1, which are not the 272s, when are they straight up, which is how I currently run them, any Idea how the are advanced or retarded compared to HKS 272's, or they the same as above?

 

don't feel bad, there is a guy putting down 400 whp in his sig with similar mods to mine. also emember I have the green turbo

 

Presently I have the GSC 272s on the car. They are coming off about 2 weeks after I put them on after a few pms with Greg @ GSC about the S1s. Also, Nils had great things to say about them too.

I asked Ted B. which would be a good cam set-up for the S1's with good top end but without sacrificing tip-in or torque too much. Basically a mostly street/sometimes track set-up. He told me -1/-3, which is what I am going to have them set at once I get the S1's in.

 

Correct. Ted B was at the shop when Shiv tuned my S1's a week ago. To get max HP out of these (while shifting your curve to the right) you have to really "get retarded". Mine are installed 0/0, and after one week with them I can say that they are very torquey/quick spool. Great daily driver setting - going stop light to stop light. Absolutely zero valve train noise, very lopey. I'm curious to see how -1/-3 does for you, I think that is going to be a great way to go.

How did your numbers look next cars with similar mods running more standard 272's?

 

I don't have the graphs scanned in but I did 275HP. Pretty similar to what people do with standard 272's. Difficult to compare because I have minimalist mods - not many people to compare with anymore. Without a cat, with 10.5HS, with O2 housing, and standard 272's people due 290's on pump (93). So taking in to account that I have a cat, no 10.5/O2, and cams timed 0/0 with relatively advanced lobe centerlines - I think I did well. But this is all speculation - nothing very scientific.
