Placement of my Bonalume blow off valve has me stumped , is it the red arrow (vertical ) valve or the yellow arrow pointing to the more horizontal direction . They both have a 3 bolt pattern .

Test drive complete .. the woosh can be either subtle or aggressive depending on your go foot .. if you go easy on the throttle , there is only a woosh on occasion , but pretty much you get the stock sound of the motor , adding a bit more throttle aggresion, you get the woosh , but is not a sharp release of pressure , and when you tromp it you get that signature pshhhhh-woosh of a blow off valve . It?s pretty cool you can go stealth with it . Once again .. if you have big hands , be prepared for a patience challenge , there isn?t much room down there. Have your tight space tools handy , a T27 with some extensions and universals .

That's how boost valves work. Even the factory setup. All the diverter valve does is give it somewhere to vent to the outside air so it's more easily audible. Less throttle for a shorter amount of time = less boost pressure = less pressure to vent.

If you have small hands it’s easier , but there is 3 bolts to unscrew , it’s tight but you don’t have to remove anything , simply remove those bolts , lift the valve and put the blowoff valve sandwiched in between , only one way to install with the bolt pattern on the blow off valve and the longer bolts get put in place of the stock bolts . Fasten down and your done .. FYI my big hands did not make this easy .. and one of the bolts is a PIA to access .

Thank you but did you remove the bumper?

It doesn’t “need” the BOV. Car works the same with or without , only difference is venting to the outside air vs venting to the Intake. Woosh vs silence.

Yes it’s just an adapter plate sandwiched between the factory valve
