Dump valves - what's the difference?
#1
'ello all,
What's the difference between an atmospheric bov and a recirc bov? Are there other types? How can you tell the difference from just looking at one and/or listening to one?
TIA.

Dump to atmosphere makes the loud "Whoosh"/ "Phssshh" noise when changing gear as it dumps excess to the air. A recirc doesn't and is quieter in it's operation because of this.
The only real "benefit" is faster in-gear spool up by fitting an uprated dump valve (and the noise if you go atmo )

just had a forge vta dv fitted with a tsl firestorm bb, not aware of any flames, but has started to pop, which did surprise me as i still have both cats fitted on my 99.
forge vta = 1pence per daft grin
