Ok I wanna know whose is running them and there thoughts about them .

 

Depending on the ramp profile they could put a new meaning to harsh, they have quite a bit of overlap it'll definitely kill your mirdrange power.

I sure hope you have an EMS, your going to need it to Pull these bad boys off.
Here are the specs for you guys that don't know

Intake....Exhaust.....@.050....@.050........LIFT.. ........LIFT...............LSA
...280.......280.............206.........206.....1 1.50mm...11.50mm.....107...117

 

He11 yeah, a Kelford thread!

The 280's are uber-agressive. I've got a little info on the 272's, so hopefully it's somewhat relavant. Here's some info I got via email last week from Kevin @ Kelford (got addy from the website) when I asked them about Kelford cams with the Mivec IX:

 

High lift (for an EVO cam anyway), but with duration and LCs that appear to be considerably short of what's needed to get best high rpm power with a big turbo (e.g. GT35R or greater).

Looks like something I'd expect for a WRC car. BIG midrange with a stout setup and small to mid-sized turbo, and ported head a virtual must.

 

i have kelfords they are bad ***, i thought i had 280's but the shop i bought them from recently told me they are the 272. so i guess i lied in a few threads not knowing my bad boom.

 

i gained 26whp on the low reading dyno dynamics with the kelfords on the stock turbo.

 

Post the graphs and list the mods and particulars so we can comment, because as of now, that isn't telling us much.

 

i dont have anyway to post a graph. sorry i couldnt help.
