dumpvalve

  1. Mito QV dumpvalve going bananas

    South Africa
    Hi all. My mito recently started jerking under acceleration. When I accelerate on 3/4 throttle the car pulls,then there is a dip in power and the dumpvalve can be heard blowing off, then the car pulls again through the rev range. The car is in Dynamic when this happens. This happens...
  2. Dump-valve on a JTD

    Alfa 147, 156 & GT
    Lovely as my SW is, there are still things I would like to improve. One thing that frequently bugs me is the turbo lag on changing gear whilst accelerating hard. Would a dump valve be as effective at combatting this on a relatively low-revving JTD as it is on a turbo-charged petrol engine?
