Hamilton Cams 07-S-006 Performance Valve Springs
|This spring allows you to run higher boost pressures and rpms without
experiencing valve float. No extra cylinder head machining is required
to run these springs. Depending on installed height, you will have
approximately 130# installed pressure.
If you have an aftermarket
turbo and are running more rpm than factory, you will see a few
problems if you are still using OEM springs. First, valve float, which
can cause serious damage to the valvetrain. Second, intake and exhaust
valves can be blown open by boost and exhaust drive pressure which
allows reversion. Reversion can hurt your power potential by allowing
exhaust gasses to enter the cylinder on the intake stroke. Inert gasses
in the exhaust, when re-introduced into the cylinder shield the fuel
particles from oxygen in the cylinder. This does a few things that
negatively affect power.
It increases the time delay from start of
injection to start of combustion, it decreases the maximum pressure and
maximum temperature reached in the cylinder and it increases the total
time needed to completely burn the available fuel. Correct valve spring
pressure is a very important piece of power production. If you are
running a tuner on an otherwise stock truck with a VGT charger, based on
exhaust drive pressure, these springs will help you.
