Can i run without a dump valve safely
Can I get rid of my dump valve without causing any harm as im sick to the back teeth of the stupid noise 
I know i could fit a recirculating one with added pipework etc but id rather do without if i could.
4x4 saff running blacks with T34.63 cut back blades/360 bearing 500 cooler etc etc

yes you can mate as long as you blank both the pipes off securely otherwise you will lose boost etc etc! your vacuum side and charge side need to be air tight!

technically its not wastegate flutter its the sound of air hitting a closed throttle and being chopped up by the compressor wheel causing the turbo to stall momentarily dropping the shaft from extremley high rpm to none and back again constantley (this is what snaps gt shafts) which also causes the extra lag between gearchanges due to having to spin the turbo back up to speed when back on the throttle

Exactly the reason I left 1 fitted to this car as it spikes at 32psi and I wanted to not kill the turbo
