hi . ive currently got a dump valve fitted but was thinking of getting rid of it , what advantages and disadvantages does a dump vavle have ?

is it true it keeps the turbo spinning while changing gear and prolongs turbo life ?

Thanks

i was thinking this with my efi engine


was thinking of taking the one off my efi.

would i get more chatter on the efi engine with a t3 conversion?

binned my d/v today, its so much nicer to drive not having that shitty noise all the time!

i get quite a bit of chatter running stage 1, 0.8bar and standard airbox.

-so youve removed the dump valve!! where's the compressed air going now??---------i think you need to go read the principles regarding turbo's-
a dump valve is a safety valve much the same for any instalation regarding compressed air/water etc-etc.it releases pressure at a given point-very basic science!! you dont have to have the -HISS- of expelled air!!! recirculating does the job but i suspect you like to hear something to impress your mates. or to make you feel better in your car! so hows that reflect on your engine then!!!-

ha ha no a dv 's a glorified boost leak,

if there that safe ford would have fitted them standard

unless your running 25+ psi u dont need one even the u dont rely
