How do you guys think the 'new' S2's will go compaired to the Kelford 272's... Do you think it is work swapping my kelfords out for the NEW GSC S2's?

Im running a 2.3L, Trust T67 + Fully built head..

Looking for killer midrange..

 

^No dont think its really worth it. Just keep the Kelfords.

 

Bump from the past!

JB, it's 18 months or so later, you still liking the mivec S2's on the stock turbo cars you tune? How do they affect spool-up? FP 4R's are the only mivec cam I've seen that really improve on spool but have decent top-end, and curious what the S2's do.

 

He'll be tuning my car on Wednseday after ER installs my S2's! I'm sure he still likes them Be sure to post my results too..

 

Here is a comparison from Cosworth M3s to the 278/274 version of the S2 (no longer available). I have loved every minute of the 274/274 S2s I had, the 278/274 in my new motor and the S2Rs that I have yet to test will be the same I am sure.

 

So the s2r's ( 278/274) are no longer an option? Im curious if i should switch to a different cam from the comps.

 

is brian crower 272 and fp red a good combo john bradley?

 

Nope. You'd probably be better off with your stock cams.

 

look at my evo 8 sig johnbradley, how much power i can gain if installing the new gsc s2

 

Kelfords are better IMO... i no they have better top end

 

well 5leeper, i love top end , probably kelford 280 plus spring, retainer are for me.

 

stock cams are better than brian crower? really

 

In my opinion yes. The BC's will gain you a little power, but you will need to degree them with an adjustable cam gear and even then won't give you nearly the gains as a "good" cam. If you're going to go through the effort of installing cams (or paying to have it done), you might as well spend a little extra and actually get a proper camshaft.

 

Lets see some proof (and please don't link me to AMS' cam shootout thread).

 

so what do u recommend kracka? gsc s2 or kelford 280 for my setup. Do i also need to install cam gear with these cams? thanks
