which way do i go ? vent to atmosphere or recirc ? my original turbo setup (406 sri turbo) runs a recirc dump valve setup i love the dumpvalve sound but have read articles that this option is not advised as problems can occur.ie that the dumped air has already been measured and catered for by the ecu/fuel system causing missfires/stalling and various other symtoms. can anybody give me any advice on my situation ? !

anybody?

im a child so air!

i reckon its probably bull about stalling etc... the big bhp skylines and other turbo monsters dont seems to suffer from it.

I believe if you recirc it before the turbine you reduce lag as it helps keep the turbo spooling.
