why do companies such as full race put the blow off valve on the intercooler what is the advantage of this? just wondering if aneybody kenew

 

why do dogs lick themselves? cause they can.

that thread was loooooooooong, but it still never said if the bov is better by the TB or after the turbo?? no one ever agread.

 

why don't you ask them....my opion i think it looks good

 

from what ive gathered from talking to people...the real benefit of the bov mounted on the end tank is essentially the main purpose of a bov, to evacuate all compressed air from the intake system, to minimize the possibility of compressor surge. mounting the bov on the endtank also, from what ive researched keeps cooling efficiency of the intercooler top notch.

so pretty much, the bov mounted on the endtank is pretty much the closest location to the turbocharger possible, so when you let off the throttle, instead of the compressed air in the upper charge pipe section just being evacuated, all of the air that is in, i believe...the lower portion of the intercooler to throttle body piping, intercooler itself, and compressor to intercooler will be relieved. especially on a backdoor intercooler design, where the bov is within what, lets say a foot from the turbo itself...will be the best place to prevent surge.

 

I always thought it had to do with the time it took the shock wave to travel from the TB plate to the turbo. The line is only, say, 2x as long if the BOV is moved from just outside the TB to the end of the IC. Yet the shock wave has to travel probably 6x as far, and a lot of that is through the IC core, which will really help to randomize and break up the shock wave into random turbulence that can help cancel itself out. The direction of the waves is more aimed at the BOV than if the BOV is sideways off the pipe, is what I'm going at... wave theory.

Plus when you slam the throttle shut, the air pumping through the hot side is almost completely shut off. The pressure in the manifold depletes and you lose torque on the compressor wheel, so this is when it can backspin. You want to vacate the pressure as close to the turbo as you can so you don't have to empty the entire line, including the intercooler, to prevent that backspin.

That's how I see it. None of this is proven, just me theorizing.

 

I also think being on the intercooler it will rid some heat from the intercooler not much but enough to make the car able to run ever so slightly higher boost in the next gear etc

 

^^ seriously....you had to bump a 17yr old thread?
