im planing to make a upgrade my hks 280 on my evo 5, my first option are the kelford 272 and the S2, after read some post here one of them took my atention, a back to back with the hks and the kelford 272 and the test show just a little improve in the top end, so is really worth it the upgrade?

Here is the post that i saw.

i have a 6262BB .82, ams vsr intake mani, ported head...

 

I have seen a ton of great results with GSC S2 cams.

 

These are both good cam sets that look very close on paper, however, the nominally longer effective duration of the GSC S2 better matches your configuration.

 

Ted b is right go with what's best for your setup not what the hype says

 

Thanks guys... I think im going for the S2 with the gsc beehive springs too.

 

I went from SC2s to Kelfords and loved the extra lower and mid the Kelfords give me. Its a noticable difference when using the butt dyno.

Just my .02

 

SC2s? Do you by chance mean S2s? I only ask because I'm struggling to decide between the Kelford 272s and the GSC S2s but had all but decided on the S2s. But if you went from S2s to Kelfords and felt a big difference in low and mid range power then... Perhaps I have to give the Kelfords a bit more consideration...

 

Haha I meant GSC S2s my apologies

But yes I did notice a difference.
The S2 offers a great top end
But the umph is in the Kelfords for me
I'd never switch back

 

Also I will have a slightly used set for sale since my new motor is complete and im pulling the old one out .Just in case you dont want to make the full price commitment.
