Btw you guys do realize only a very small amount of air is expelled by a BOV? 95 percent is used up spooling the turbo anyways…. so again I say this is a sound mod. The only tests that have proven to benefit with BOV’s were built cars or cars with a turbo upgrade. The stock TD04 needs all the boost it can get… so no need to release the pressure nonstop.
Again read up. You’re correct I should of elaborated. BPV’s and BOV’s do have the same exact function, but perform it differently. Stock boost levels, or stock turbos DO NOT, I REPEAT DO NOT need aftermarket BOV’s. It’s purely a sound mod if you don’t have big power to back it up. When I got my SRT4 an HKS BOV I lost a couple HP dyno proven.
The reason a turboback gives gains is because most the backpressure is in the DP… and when you go catless DP especially you eliminate a good portion of that, especially when combined with bigger piping catback on a turbocharged car. A Catback alone though has proven countless times to give very little power and more sound on turbocharged cars.
So unless you’re trying to be a ricer and make noise or you have a large amount of power that needs to be regulated from the turbo you have ABSOLUTELY no need for an aftermarket BOV. Multiple tests have shown a loss of power from aftermarket BOV’s vs stock BPV’s. It’s not like you risk detonation at the power this bug eye is putting out. Why would you want a BOV releasing the pressure when you’re not boosting much to begin with? It’s stupid.
Yes it’s a bypass valve but until you crack 350 horse like I said you don’t need aftermarket BOV, Correct though a Bypass valve isn’t exactly a BOV but they both do the SAME EXACT in that they prevent compressor surges. One releases the air the other recirculates. Tests have proven countless times you LOSE power with a BOV not gain.
@clippersfan2004 nah dude a STI comes with a BYPASS VALVE, not a blow off valve. its 100% recirculating. Our subaru’s dont generally like 100% atmospheric. I went with the Go Fast Bits 50/50 bov for a good compromise.

factory turbos use recirculating valves it is actually supposed to be more reliable. But some people say blow off valves reduce turbo lag. I don’t see how I guess because it isn’t routed back into the intake like a recirculating but you get a bad ass sound
Um ALL turbocharged factory cars COME WITH a BOV man. Paying for one that makes noise so you can think your car sounds good is ricer. The aftermarket upgraded BOV’s are actually made for cars putting out serious boost to prevent engine detonation. So again. ALL TURBO CARS HAVE A FACTORY BOV. Anyone who buys one is like the same ricers who buy a muffler. It does NOTHING but make noise.
@clippersfan2004 A BLOW OFF VALVE IS THE MOST IMPORTANT PART FOR YOUR TURBO UNLESS YOU WANNA BLOW IT. DOESN’T MATTER WAT CAR YOU HAV IF U HAV A TURBO U NEED A B.O.V.
A BOV comes standard on all turbocharged cars and doesn’t need to be upgraded until you’re putting down MAJOR power. Only ricers get aftermarket ones to make alot of noise right away. The stock ones on the WRX are made to withstand approx 400 horse. You lose power if anything because a BOV releases excess boost but assuming the turbo can handle it that= more power.
See this is what people who watch fast and furious thing. A big top mount is just as efficient as a front mount unless we are talking about a 600 hp car. Also you can just get a tune and skip the wastegate. I got a tune that has taken me from 190 hp 200 tq to 230 horse and 260 plus torque. My boost went from 11 psi average (2.5l boosts less) to 15 PSI average. BOV is one of the absolute worst mods for a WRX.
@clippersfan2004 hey bro u dont need a downpipe in a turbo to make any power u jus need to get a b.o.v,front mount,boost tap,wastegate,than ull be boosting around an average of 16 psi.
It did seem a little quicker than a nearly stock 2.0 but I highly doubt any engine mods. What could he do? Cams? Bore? I mean the EJ20 is fine with the stock motor until he’s reaching high 200′s- low 300′s. The noob didn’t even do a slip he did a clutch dump. The worst possible thing you can do to an AWD tranny especially the bug eye’s which were made of glass.

No idiot… I said a CATBACK is nothing but noise.
@clippersfan2004 you telling me my full turboback on my 98 sti doesnt do anything but make noise?LOL stick to honda bro

LOL. Factory turbo-charged cars should come with a stock BPV (bypass valve): 100% recirculating. Not a BOV (blow-off valve): 100% atmospheric.

he might have alot of engine mods and or swap.
som people just like to take the cheap way out just to get something that sounds nice thats they way some people do it cuz they are fags
fuck ya bro!!!
