Not neccesarily a dump valve, its usually when instead of being a dump valve, there is just like a gap in its place (im not 100% sure) and this causes it to "chatter" which is what you hear after the revs. It could be where the turbo is getting confused and fuel is getting put into the wrong places but that gets confusing :) Hope this helps
turbo chatter/surge is "unused" (lack of a better word) boost going back into the turbo, causing the impeller (correct me if im wrong on that) to stall, hence the noise. BOV`s are designed to prevent wear and tear caused by this.

abmeraz86 2 years ago
its a 2.5ltr 5cylnder turbo engine, 225bhp as standard, but highly tunable as shown in other vids :) the RS is a better choice by far tho

Easily the best sounding exhaust system on a ST/XR5. Hopefully I can get one in Australia for mine.

sounds awesome ive been tryin to get that sound out of mine but it wont do it because of the recirculating valve how did you get past this

I like the turbo chatter, and you can see it chatter when he views the front vent.
