What's the best way of telling if I'm getting surge?
I can't tell if its the APS air feed or indeed compressor surge noise. I basically get a chattering noise on full throttle only when the turbo comes in to high boost, 1.3 bar. It's a VF34 on a 04 WRX engine running 346 bhp. If it is surge I wonder if it could be the SSQV causing this?
Possibly although the spring on mine seems pretty soft compared t my old Blitz one. Can't you get the effect of to much air being forced in to the compressor also resulting it a stalling/surge noise?
Hmm that's what I thought. I'm going to change back to the recirc to see if that has any effect, failing that am I looking at a good adjustable bov do you think? Or is it the fact I'm running the monster APS induction?
