hi guys.

something in#s wrong wi my sup twin turbo,

the boost is reading fine but when its on full boost at about 11 or so psi i get a howling sound like there is a werewolf trapped under the bonnet, i am thinking burst boost hose or intercooler, what do you guys think, also it sounds like its from the nearside/ or drivers side if you prefer

mines sounds like the one in the video but its a jspec an its really low mileage so don't think its the turbos, also i am still getting full boost and have a blitz dump valve fitted already so i know its not the factory re circ valve either, wil just have to keep searching the engine bay for the noise,

 

 

also it only seems to happen when your driving and come onto boost all the way up to full boost
