so u made good gains i see , hope us on non mivec can also make good hp and also tq to race our evos

 

i want Kelfords now...

 

..

 

so has anyone switched from 272 hks to kelfords 272

 

If I were to upgrade from stock to kelford 272's would it be recommended to upgrade springs and retainers? I will be running off stock turbo and will most likely be boosting from 21 -22 psi.

 

I think adding springs/retainers is a good insurnace policy with higher lift cams. Look at it this way...it's cheaper than a floating valve.

 

im adding these cams with beehive springs and stock retainers

 

im gonna go with the kelford 272's over the hks but has anyone taken the risk of stock valvetrain? if so how long :P

 

yep , my friend raced his fp white kelford cam evo into a 11.9 1/4 mile stock valve train

 

+1 for kelfords, love em

 

Just in the second day switching to Kelford 272 from HKS 272, am using Green on EVO 8 so should fit your criteria.

It's much more aggressive all around, very slight longer spool but very very strong all around. Very drivable but idle is still tricky (Motec M4) and I still have to settle at 1200 rpm idle, otherwise very unstable.

Have to drive more but so far am very pleased with this Kelford.

 

gfng, did you get kelford after all?
