GSC S2 or S3 vs Kelfords vs FP4r

[IggyBcool]

Built 2L 9:1cr 9200RPM limit
Beehive springs +1mm valves, JMF Race SMIM, PTE 6262 Turbo 700hp range.

Right now the head has some Web's in it and I'm looking to upgrade. I'm looking for real world experience with these cams. I honestly don't have a clue which direction to go as my last set of cams were BC 280's and I was pretty disappointed in them.

I'm not too too worried about streetability as the car does not get driven on the street much at all. Just wanting across the board results and power.

I personally would go with either the Kelford 272's or GSC S3's which are advertised as 274's.

We have a great success rate in the Evo's with either of those cams.

S3s are a 280 duration and nearly 12mm lift cam...definitely not comparable to a K272. The S2 is the correct comparison.


You can not go wrong with either of those two choices. (K272 or S2)

Sorry I mixed that up you are right my bad. S2's is what you want

Dang.. No love for the FP's? I had someone mention a Kelford 276/280 combo. So basically it looks like you guys are saying I should stick with a 272 based cam.

9,200rpm catches my eye...what turbo and will you actually be revving it that high? I have stock cams still so I have no opinion, it just seemed like this was information that ought to be out there when making a cam selection.

Going to start out with a 6262 with a s90 TB and JMF race SMIM then maybe jump up to a 6765.

[90BLACKAWDTSI]

If you plan to go bigger might as well look at the S3's

[11secdsm]

I would agree...If you're planning to go 67mm, then go with the bigger cam.

ps...6766 is a much more efficient turbo than the older 6765.

I think I'm going to give the s2's a whirl.. I've got a guy local with a set for cheap cheap.

If you found a set of S2s for cheap, awesome. From personal experience, I ran S2s in my 2.4L/FP Red EVO VIII and loved them. They are the cam to get up to the 8,500 RPM mark. I know of a good friend that swapped to S3s and only suffered 100-200 RPM loss but gained +40whp up top.
