| So, if you're correct, then a stock recirc would basically leak if subjected to any boost pressure above roughly 3 psi. But why is it that people are boosting to 15 psi or so without buying BOVs and still using a stock unmodified recircs? You obviously don't understand the idea of a pressure differential or how a BOV or recirc valve works. You are thinking that the valve is a simple pressure relief valve that relies solely on spring pressure to set its open point. When the same pressure exists on both the piston and the diaphragm the valve is not open!! It's no different than if it were off the car sitting on a table.... equal pressure on both sides and the valve is not open. In fact, I would be willing to bet dollars to doughnuts that the valves would not be open if exposed to your 3 bar twin T88s because if they are connected properly the effective pressure differential will be zero. Please don't misinform EVERYONE on this subject when you don't understand it.
