Hi folks, I've got a question about the sounds that dump valves (BOV's) make. In the fast and the furious film the dump valves don't make the usual wooshing sound. To me it sounds more like a rattle. Is this a particular type of BOV i.e. HKS SSQV or Dual piston type?

 

Cheers, Mark

thats the sound of an external wastegate ;) not bov

more like a rally car sound, love that sound!!

Cheers bud. That makes sense

do u mean wastegate chatter ?? or compressor stallling.its the compressed air bouncing off the blades after its bounced off a closed butterfly.

i think he's thinking as i was a while back of compressor stalling, which i think we agreed was not very healthy for the engine, sort of whoosh noise that chatters like fook

Hi Mark

 

I believe the dump valve on the Eclipse in the movie was a Greddy type S. I've heard this dump valve on a S13 and S14 and both sounded identical to the Eclipse.
