@@ddinoboy it makes the tradmark “sight whistle” sound on my boosted Honda but on my DSM at 30psi I feel like I’m pushing it to it’s limits, most of the people on CZcams you hear are running around 15psi, making it “whistle”, I feel like at 30psi it’s forcing the air out so fast it doesn’t have the airflow needed to make the typical type s sound
It's definitely not tuned for the whistle. You have to loosten the top screw, let it out and it will whistle. There are several big turbo builds which the iconic whistle present. You eliminate the whistle by screwing too far down.
@@AndesCandies86 literally can’t unscrew it any more than it is, look how far out the screws are at the beginning of the video, trust me, it’s adjusted properly
Probably performance difference under high boost. I did tial knockoffs like 5 years ago and it was good on low boost but on high boost, they were bad. Boost spikes, inconsistencies in opening and closing etc
It's not about the sound, it's about what it does or what it's supposed to do. A proper blow off valve takes the load (excess energy) from the turbo and dumps it so it doesn't damage and put too much pressure on the turbo. It also makes it sound awesome 🔥 The fake one just makes it sound awesome, but your turbo won't last long.. probably 🤷🏾♂️
the fake is engaging too slowly and is not flowing enough air to keep up with the boost in this build. that is why you can hear more of a hiss on the second one and more of a “pish” type sound on the first. to be fair even the name brand valve is underpowered but much less so than the knockoff.
I believe NGR bought the rights from Greddy and made it more durable with a silicone diaphragm and adjustment screw that doesn't strip like the original .I have the NGR Type S and love it. It will whoosh and whistle or just whoosh depending on how its adjusted. Bought mine used for $80 and zero problems in 3 years running up to 20 lbs boost.
@@dylanjamesryan9432 I had an electronic boost controller. Way more consistent than just relying on springs. Not sure how you can gauge how much psi a car is running from the sound of its hood exit exhaust 🥴
Hey that’s the blow off valve I use (cheap one) It’s claimed two turbos but thats cuz I was too lazy to see what was wrong. It was completely blocked off since I got it and I had to take it apart and reconstruct it. Works perfect now
Ugh.. the fart can on the back definitely steals the show 🤣 Reminds me of when I go to my great great great Grandparents after there Bean and Cheese Macaroni Lmao
All of em work the same in my opinion, some are designed to be super loud but this is the style most people use, as long as they dont break its fine no need for a super expensive one. Pretty hard to break a blow off valve.
Gotta be more specific bc technically they're both "Real" BOVs . One is a name brand Greddy valve and the other is a "Knockoff" brand that basically sounds the same, but what is t discussed is the performance and THATS what is more important. If you think a BOV is for making a sound then you deserve to get ripped off. BOVs serve a purpose. They prevent compressor surge, and when you're making power, it's important to make sure the turbo is flowing good.
🙋🏻♂️ Hum.....for someone like myself is a huge fan of the Greddy Type S and still currently running the same BOV after all these years, hum.... sir something wrong with those BOVs and they look beat AF. My Type S still sounds like you're breaking glass and loud AF 😉 I did experiment a Knock Off and it's close but not as loud as the real deal.
Right? The cheaper prob isn't as efficient, so you may want to go bigger than you'd think, and it may not last as long, but when you can get 8 of them with change instead of a brand name decal, there's really only one choice
I’m gonna have to agree with the people in these comments that yours isn’t adjusted properly, I have a 2g 4g63t with a real type s and my still has the whistle
Its not about how it sounds. It's about how it performs. Most of the Ebay stuff is junk but every one in awhile some absolute gem shines through and takes the win. Like the GT45 Turbocharger which they no longer sell die to companies changing hands.....
30 dollar one sounds fine to me
That’s what I’m sayin!
I came to the comments to make sure i wasn’t crazy
Not really…it doesn’t have the fluttering sound.

It has a hood dump straight off the turbo outlet so I’m not surprised
That awkward moment when you realize you have two fakes in your hands
or a "real" one with fake replaced spring
I’m dead af lmfao
I was thinking the same thing lol I've only had two turbo engines and both sounded better than that crap
I don't care about the sound, i care that it operates exactly the way the tune demands.
Under rated comment!!!
Lol ... How does the tune demand the bov??
@@street954depending on how the BOV opens will play a factor in how the power comes on when you back on throttle
Well that's the $30 gamble isn't it. However that $30 gamble could end up a $3000 fail.
@@vickramos9234 what does that have to do with the tune?? (Hint, it doesnt)
I don't think they are adjusted properly. I'm not hearing the type-s schwing sound on even the genuine..
they are indeed adjusted properly, the screw is loose enough to let the BOV open but not too tight to where it cant open and cause flutter
@@Austinarchu I don't know, just doesn't make the trademark sound. What do you think when you hear the other loud Type-S BOVs on CZcams?

yup ripping us off when can go with the $30 one hahahaha

I dont think this guy understands he can rev while stationary
It’s much harder to create boost when under load

Still waiting to hear the fake one 😅
Logos are expensive, they sound very similar ,if you put an hks decal on the fake one id believe you
Both sound shit 😂
Had a HKS SSQV on my Evo 5. The turbo sounds were insane.
All due to boost psi. This eclipse sounds like 5lb spring
@@dylanjamesryan9432 I had an electronic boost controller. Way more consistent than just relying on springs. Not sure how you can gauge how much psi a car is running from the sound of its hood exit exhaust 🥴
turbo flutter on an ssqv? a bovs entire purpose is to prevent flutter, so somethings wrong there.
Fake sounds better
They definitely both sounds pretty close!
Had the type S for about 7 years and 100k miles. I missed that sound so much. Man was I disappointed when it wasn’t there.
I have a hks one and that one sounds amazing. Always loud even at low boost or barely boost you can stil hear it very nicely
That full throttle demo was impressive
Hey man if its a sound contest and im broke you know which one im picking
Bypass valves and blowoff valves are two of the same but different obv you can like tune blowoffs

Wym like clogged or a cap from the factory?
U paid for 2 turbos, but then ran them through a $30 BOV? lol
@@501Labs 5 turbos
@@jonek473110 turbos
Not me immediately recognizing the knock off as I just put it in my eclipse…. I got mine in some kit so I can’t even complain sound for sound
Ugh.. the fart can on the back definitely steals the show 🤣 Reminds me of when I go to my great great great Grandparents after there Bean and Cheese Macaroni Lmao
Sounds set very soft. Mine doesnt sound anything like these 😅
Bet your dick is massive bro 😂
The flutter is compressor surge. My k04 gti makes it because it doesn’t have a bov. They use a diverter valve instead
One of the best sports cars ever made right there.
GUYS, HE'S DRIVING A MODDED ECLIPSE IN A PARKING LOT!!!!! What a movie reference!!!!
Oh I haven't seen one of those greddys in awhile. My friend had a talon with one me
Both sounds cool as long as both are doing the same job. It shouldn’t matter. It’s a matter daddy thing.
2g with the evo 8 wheels is fucking ELITE
Lookat that beautiful eclipse 😍😍😍
Scenery, sounds, car, all make me want to play Juiced, need for speed and srs and other racing games…good times smh
Didn't need to drive it to hear the difference 😂😂
I haven't seen an eclipse for some years, last one I saw was at a junkyard and I went back to buy it and somebody was already loading it up
They both sound good. Take it apart and show us the spring inside it thats the important part.
Cool car.
Ahh eclipse (:
Miss mine
Locked up in the garage.
Sounds almost identical 😂
I had a greddy type S on my mr2 years ago and I remember it be louder and higher pitched. I might’ve had more boost pressure tho
They sound roughly similar to each other, but I can definitely tell which one is the fake one versus the real one when you show them together
Both sound good
If you adjust that real one right, it will whistle like the eclipse in the fast and the furious.
Are you running speed density then? Or is it a recirculating setup? Also do you tune it yourself?
When you find out you just have a bad spring or vacuum leak and they don’t change sounds regardless
The greedy I had would whistle so loud. It was the classic wwwwiissshhh that you here on fast and furious 1
All of em work the same in my opinion, some are designed to be super loud but this is the style most people use, as long as they dont break its fine no need for a super expensive one. Pretty hard to break a blow off valve.
I know the flutter is compressor surge and is terrible for the turbo, but the sound of a crushed greddy knockoff is unbeatable 😂
I'm just glad they don't both sound like a pigeon is getting curb stomped.
The 250 sounds more in tone to the car but the 30$ still did a pretty decent job
They sound the same on that diamond star motor vehicle.
They sound pretty freaking close in fact the cheaper one is louder and more clear
It’s all in the spring.
They sound exactly the same lol 😂😂
the fake sounds horrible but the real sounds pretty good
Almost just need that extra stutter at the end

You can adjust the sound by tuning the vacumn
That car sounds like hell. What did you do dump the exhaust out the bottom into a 6 inch cannon?
Here's the thing though BOVs aren't a cosmetic to most people which is why the $30 one is better for most as it's works the same
I have a real one on my gsx and it sounds nothing like this lol wtf
Same. Mine whistles loud as hell.
Yeah sounds good either way not the most wanted car but deff a tuner classic and a sweet ride love man don't see enough of then
The fake sounds pretty good honestly
Those purple knockoffs are great paper weights. They all cause bad vacuum/boost leaks.
Just put the spring from the good one in the 30 dollar one and they'll sound identical
Either your car makes fuck all boost or they both sound the same
Sound should be the last thing you consider when building, Performance and reliability come first.
How come all the 4G eclipses I see online in videos and for sale all look so clapped and have hood dumps. I love it.
Welp sound dont mean jack but when you get a boost leak and cant figure it out you know where to look
As long as it works the same. Save money. Now for important things like brakes don't cheap out on some Flintstone heel rotors and pads
The one that does the same job for less is more intriguing in my opinion it doesn’t sound like a difference much
I mean its about function, but i think the knock off could be a temp fix if you dont have $250 on the spot or a spare one on hand
I would rock the fake one for the price sounds just as good but if it adds power and shit add the real one
What if I told you they weren't just for making the sound 😂
The real one has a slower release sound the fake one had an instant release
I’ll keep my diverter valve, thank you
Exhaust sounds like it's about to fall off
anything fuel related i would not get from ebay. but this is fine
They do the same shit. Got two Chinese on a twin turbo ls.
To me, almost identical
🙋🏻♂️ Hum.....for someone like myself is a huge fan of the Greddy Type S and still currently running the same BOV after all these years, hum.... sir something wrong with those BOVs and they look beat AF.

Is there a part 2 for the difference?
I missed the 90s .... the type S was $30 used
So you're saying you have 2 different profiles? That releases the built up Turbo pressure into the atmosphere and sound the same???😂😂
That mitsi is worn out my guy like that old greaty
Oh, so exactly the same.. cool.
You got intake air in that head light hole or just couldnt be bothered to fix it ?
It blows off intake pressure. Its doing its job. Fucking bargain if you ask me
