anyone heard of the sard racing blow off valve,,,i heard one at vakamon,,,whoa that valve sounds mean,,,,its like a fluttering sound and then you get the psssh,,,,awesome,,,,but i think i'm gonna get one,,,i heard it mounts under the intercooler on the y pipe,,,anyone heard of this valve on a wrx...holla back yo

 

ive had 2. one on my top mount and one on the front mount... true they sound mean but they stick and need adjusting a lot. Get an hks.

 

yup. had one for years already.

flutter noise isn't the blow off valve.

i have a hks,,,,but the sard one sounds mean....

 

i guess this is a newbie thing again....

don't worry about what the bov sounds like buy a bov because it works. sounding mean, looking mean doesn't matter if you don't have the upgrades to justify the bov anyway.

 

true about that,,,,,but i have upgrades,,,,,uppipe,downpipe,tmic,txs utec,intake,hks carbon ti exhaust,,,255 fuel pump,,,sti injectors,,,and tein coilovers,,,,if you go vakamon,, they have a evo with the sard racing blow off valve and i heard its better then the hks or the rfl...better spool up between shifts plus that blow off valve has no gaskits or clips to worry about wearing out......

 

and the fluttering noise does come out threw the blow off valve,,,,sard jus came out with there line of the racing blow off valve

 

Anyone have a sound clip of it? And how bad is the maintenance?

 

Jon is right..Just the Sard BOV alone wont make that fluttering sound your describing...trust me i have that bov as well ....i have noticed on every other car w/a FMIC it has that cool fluttering..but not with the Subie TMIC...

i ran it on a 04'wrx w/cobb 2.5 (vf-34), jdm STi tmic, uppipe, intake, ETC. and it did not sound like what you describe...

if you dont beleive us.. then by all means try it for yourself...i did..LOL

good luck

I'm sure I've posted this before... but the fluttering sound comes from compressor surge -- the turbine blades pulse through the air due to the bov being too tight and air having to escape back into the turbo. This is not a good situation because it can damage the turbine. You can make almost any bov have the fluttering noise provided they can be tightened enough to keep the air from escaping properly.

 

So how did it sound? Anything remotely similar to an HKS? Greddy?

 

this is true...usually when you start hearing a fluttering noise comming from the Passenger (turbo) side of the engine bay and not the BOV side that usually is a sign of something bad...

out of curiosity, you have all those mods like sti injectors and 255 fuel pump on stock turbo?

 

so who tried the sard racing valve,,,,,and where did you mount it....curious

 

stock location...how you ask? ...i made the flange myself
