I'd go with the GSC S1 268/268 grind over the Kelford 264/264. S1 should make a bit more power while retaining the stock valvetrain. I don't mind spending the $$$ to do it right with the 272's but I don't think those cams match the stock turbo powerband...and I don't plan on switching turbos maybe to a EVO IX but doubtful.

I have Kelfords 272 and did not make hardly any WHP with the stock 9 turbo. Although, I really fill them working at 6000-8500 RPM's with the FP Red.

Go with the Kelford's for sure you will not be disappointed!! The S2 is a nice cam as well, just not as beefy as the Kelfords

Can somebody explain me about gains in power on stock turbo with anything more than stock cams? As far as i understand the turbo's gona run out of normal compressor map - there is not enough stock turbo to work with 272/11 cams!

got the Kelfords installed on the stock turbo and I absolutely love them! What a difference throughout the powerband and not losing anypower up top.

I have a brand new set for sale too if you know anyone else interested in getting a set of those cams.

What I meant was the stock turbo typically is out of breath at higher rpms and the power curve will downward slope. Especially on the 8 turbo
