Now that most of the reviews for cams are old, I don't know what to get. I'm debating between the GSC S2 and Kelford 272's. GSC's are 274/274 11.2mm intake, 11mm on exhaust while the kelfords are 11.0mm for both. (a lot of reviews for the gsc's are about the "good idle" for evo 9s.. i have an 8 so idgaf about dat).

Side note: 91 octane, stock frame turbo. Looking at the bbkB turbo in the future.
Thanks.

 

Ive got S2's stock turbo atm and it idles lopy, although you can richen the mix to remove the lope if thats what your worried about

 

Gsc ftw!!!

 

Evo 8 everything else being equal, the S2s were worth 25whp more than the Kelfords. There are a few threads on this.

GSC S2 are the cam of choice

 

What did you say!?! Well then I guess I need to start looking at a different cam.

 

ty, I'll take your word for it and pick the S2's then

 

id go with kelford 272's, they won the shoot-out between all the major products.

 

Kelfords are good, but its hard to go against what JB posted. He's got a lot of experience with different products. I'd take his word for it and just go with the S2's. Plus they're proven to perform. What's not to love about them?

 

You can't go wrong with the GSC S2 cams, I love mine.

 

Kelford won the cam test but then again it was the first batch..Gsc 2 cams make more power on the new batch then kelfords..They have excellent mid range and get freaky up top the more you rev it the more power they make..I would recommend a beehive of some sort too.Also kelfords are known for phantom knock!

 

+1 for gsc s2

 

I switched to the S2s as well.

 

How high does the idle need to be set with S2s? How do drivability and off boost torque compare to something like GSC S1s or Comp 280s?

Thx.

 

After warmup mine idles around 900ish...probably also due to the cold weather here in PA.

 

Kelford won the cam shoot-out like three ****ing years ago. GSC has made at least 4 revisions that i know of since and now have the absolute best cams on the market. PERIOD. Don't take **** like that to heart. It is old and the car community is always evolving into better products.

GSC S2 FTW!
