Seat Pressure 165 lbs, comes with retainers and locks
If
you are over 30 lbs of boost/drive pressure or over 3500 rpm with your
12 valve, you are experiencing a few negative things.
First, valve float,
which can cause serious damage to the valve train. 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. We have seen
10-12 hp increases with customers changing their 60Lb. spring to our
beehives.
These springs will work well up to 4,500 rpm with moderate
cams and OEM size valves. If you are spinning over 4,500RPM with a
healthy cam, and/or larger valves, then you need to look at going to our
dual spring for safety and valve control.
