Right this might sound really strange and I'm pretty sure i know what it is but just want to check.
Ive fitted my new charger plate and relocated my recirc valve (with a much longer run back to the charger) and am now seeing 6psi (2 more than before). Good news yes. Bad news is if i come off the throttle at highish revs/boost (above 4k), i get a nice chirp from the engine bay which sounds like a momentary belt squeak. My guess is the recirc valve isn't big enough allowing pressure to build up and try and stall the charger. Am i right here or is my charger just f*cked? lol
Its not the engine as I've had the belt off and that runs nice and silent so I'm happy its not about to go bang but i know these chargers don't last 5 minutes when they back up so want to find out if it is that so i can get it sorted. If so, extra recirc valve i suppose?
