valve springs pressure

[tryblue]

hey yall are the 60 lbs springs on both sides of a 12v good enough for 70psi boost pressure with a lot of volume or do you all use more spring pressure?

 

[Timebomb]

A 60lb spring is not 60lb on the seat, its 60lb over stock pressure wich brings it to around 190lbs on the seat. You will be fine.

The discriptor "60 lb" is named for the exhaust brake pressure they were designed for. I run the Cummins 60 lb springs and have for 7 years now.

They will hold that much boost and more

they are a good start for all but a few aplacations .
for the all out agressive cammed engines the selection is wide open

We tested the 60LB springs, we found:
The seat pressure on these springs is ~115lbs at the installed height of 1.950.
At 400 lift, the spring pressure is ~192-195lbs.
At 500 lift, the spring pressure is ~210lbs.
