Are you getting confused with Wastegate Actuator?

BOV is basically a noisy equivalent of our dump-valve... On 17th Nov, 2014 Tom Fenton said:

No I am talking about the Blow off Valve, not the wastegate. Some of the ones I see on Ebay say they are adjustable with either shims or springs. This is why I am curious, I am not sure what the adjustability would be for.

Thought id just add to this rather than start a new topic... the universal recirc valves that u can get rather cheap on ebay.. can these be used as dump valves by just leaving the outlet to atmosphere?? U can get pretty much the same thing as a dump valve i know but the recirc ones come with different rate springs where as the dumpvalve ones dont.. On 24th Oct, 2015 jonny f said:

It's possible to induce compressor surge with an adjustable bov, they give an adjustable resistance instead of full pressure relief. Gives the boy racer chipmunk noises, puts a grin on your face but obviously it's not good for the turbo. |

Just fit a bosch recirc bov from a vw or Audi turbo car, black plastic 99 p on eBay, you can plum it back into the air box pipe work.

Not much left of standard, the airfilter is behind passenger headlight, and pipework for dumpvalve is on the otherside behind drivers headlight on the intercooler pipework, ill find the type of thing im looking at.. hang on...
