Competition 24V Valve Spring Question???

[justinp20012500]

I don't know if this has ever been covered before...

I have twins that make about 60 PSI (with woosy injectors). If the valve spring is able to apply 75 pounds of satic pressure to keep the valve closed, is that enough to keep it closed when there is no cylinder pressure??

I know that on the compression stroke the combustion pressure will be able to hold the valves up, but what about on the exhaust stroke when the 60 psi is pushing againts the intake valves???

If you look at it one way, lets say that the boost does push the valve open, would it assist in evacuating the exhaust gasses???

Just a brain fart... .

And if the above is a problem, where can I purchase heavy rated valve springs?

I see that they offer them. (Price WOW!!!)

But, how do they perform, do I really need them?? Is my first post a problem with other 24 V running high boost????

I wouldnt worry too much unless you start running higher rpm or you get valve float.

Really not my expertise!

I would at least check yours to test on seat pressure, and shim them . 060" or so if you get serious about boost and RPM. Just be cautious about coil bind.
