Engine Bypass or Bypass Valve for TRD Supercharger

Bypass or Bypass Valve for TRD Supercharger

I came upon this article from Import Tuner magazine regarding the bypass valves for the supercharger.

"Compressor surge is a problem that affects most superchargers and develops when the supercharger is creating boost, but the throttle shaft is closed. Although not a problem on some low-boost (5psi or less) applications This condition can occur under deceleration or while shifting between gears, and can cause the car to sputter and chirp. Under surge, the compressor forces air into the closed throttle body until the pressure inside the throttle body is higher than the amount of pressure being created by the supercharger, and the air tries to pop backward through the supercharger. At that point, pressure is released inside the throttle body and the compressor forces air back through the supercharger and into the throttle body, which again has nowhere to go, and the process repeats. While surge normally is not highly damaging to the engine it is certainly annoying and can cause damage with time. To eliminate these problems under surge conditions, a bypass valve (sometimes called an anti-surge valve) is used to release the excess pressure. The bypass valve is actuated using intake manifold vaccuum, which opens the vent valve and releases pressure in the air-intake. Air is either released into the atmoshpere (blowoff valve) or recirculated back through the supercharger compressor (bypass valve)."

Our superchargers could use one of those, but we're not really getting that much boost. Do you think this is worth getting?

somebody on the board has one on their TRD supercharger...........he used the one for the tacoma. I think his name is TRDgreg or something like that.

from TRD website..

00602-17620-670 Toyota Corolla 2003-2004 Supercharger Components
Actuator, By-Pass (Inline), 1.8L Supercharger $40.95

if what it says on Import tuner is true... then i rather spend $41 and get rid of the problem..
