dump valve ?
Turbo Mini Forums

first cheers turbo phil that did the trick running sweet now. as for my next querie when purchased turbo motor came with modified plenumb chamber was going to blank off but friend gave me a dump valve so connected it to pipe on plenumb now i do not know what the little pipe on the other end does or where it goes
any ideas would be gratefull

the small pipe goes to the inlet manifold, ie after the throttle,

the function is when the throttle is closed the depression in the inlet manifold will suck open the dumpvalve, this will provide an escape for the pressurised air which is now obstructed bu the closed throttle.

does this meam tapping a small outlet into the inlet manifold

Thats what I did,well drilled and press fit just behind the servo take off

exactley as dangerouse has it

forget about the yellow pipe that dangorous has in the pic as its for the WASTGATE pressure side to open
