Ive read of some guys saying they are running for example 5psi springs and then making 10 psi. But that doesnt make any cense. Pressure is pressure, My best guess and im no expert would be that they have bad waste gate placement or they are running too small or a wastgate.
it will really depend on how much boost your trying to bleed off.
if your trying to bleed off 10psi i would think you would need a large gate
but if your trying to bleed of 2-4psi then you could get away with a much smaller one

They are basically a vavle that is operated by actuator. Its the actuator that see the presure and opens the vavles, not the exhaust gas (in this the boost air). So if you bleed of some of this boosted air before it reaches the weastage you can run more presure than the spring is setup to hold. Obviouslt once you start to push WAY past the spring presure the exhaust gas itself will start to push the gate open. This is when a higher rate spring is needed.
Thanks,
Chris.

Verdad Gallardo So the actuator recieves pressure from a charge pipe seeing positive pressure? So this keeps the valve closed for pressures slightly above its spring rate?
Could you just not hook up the actuator, and have it based solely on spring pressure?
Im still confused as to how you would get this to open and bleed off anything over a low pressure.

think you need to look into how weastgates actaully work a litlte more!
They are basically a vavle that is operated by actuator. Its the actuator that see the presure and opens the vavles, not the exhaust gas (in this the boost air). So if you bleed of some of this boosted air before it reaches the weastage you can run more presure than the spring is setup to hold.

I understand stand how you could achieve 10 psi on a 5 psi spring. I just dont understand why you would run it that way on a single boost setting setup. May be I miss understood the build I was reading about.
Sorry for confusing anyone.

The actuator has pressure on both sides. If the boost pressure on both sides is equal the your spring rate is the default in this case 5psi . So you would make 5psi. Now if you bleed off some pressure on the lower side of the waste gate this increases pressure on the back side of the spring holding the waste gate shut until the difference in boost pressure (between reference 1 and 2) + the your 5psi spring. (whatever amount you set to bleed off).

It is how alot of people have done it. However i think ti would be intresting to see the throttle body used as a form of boost regulation. It could even be tied back into the traction control system to help reduce power when you loose traction.
On a supercharged system ti would also reduce the amount of componenets you have to worry about. No need for a weastgate if the throttle is modulating the boost for you.
