Well why on the catalogs says beehive kelford springs (for cars running up to 2 bar) 2 bar is around 29psi. Does this mean i run lets say 32psi over stock rpm 7600rpm will result in problems??? all this on a 2.0L stock internal evo.. just got my Kelford 272 and im looking for the best option for the price and performance output on springs or if i have to get spring and retainer???

 

i have manley springs and retainers on my kelford 272s and they work pretty damn good

 

its as simple as this get spring and retainers end of story as stated earlier to many bad things can happen without them

 

I had valve float issues with stock cams at 8k rpms. Get the springs and retainers.

 

nice bump of a thread from 2008. well played
