Notice on the site is says up to 9k, but the s3s dont have a rev range.

Id rather not change from s2's to s3's since im a 2.0lr, but im wanting to rev 10k once i throw on the pte 6870. Atm im revving to 9k for reference on a pte 6266. just curious as to if any high hp guys are revving 10k+ on gsc s2's.

assuming the rest of the engine can handle it no problem, will the s2's?

thanks.

 

The s2 do not have enough effective duration to make power at 10K rpm. 9k is the most they can go powerwise.

They'll do it, power just will likely be quite flat up top. Would be ideal to put S3's in it. You'll recoup most of the money by selling the S2's.

 

have you considered the STM 650 Cams? End of this year I wanna start to move towards a big turbo setup and that is what I am looking to run.
