  • In this video, Kevin covers anything and everything Blow Off & Bypass Valve. Most, if not, all factory turbocharged cars come with a recirculated air system from the factory which is definitely a good thing! Want to learn more? Check out what Kevin has to say!

      Great video man, I have a 2018 Hyundai Elantra sport along with a HKS BOV. I have a adapter that replaces the diverter valve and the BOV sits where the diverter sat. I just don’t know if I need to bypass the solenoid or connect to it still. Also have no clue where the vacuum lines should be going. Mechanics around my are have zero idea how to connect a BOV or how to rout the vacuum line. Any tips ? Thanks

    Ex-turbo test tech here - Compressor surge on closed plate is BAD. Will prematurely wear bearing(s) and shaft. If they get too worn your compressor will begin to contact the housing. TLDR: you will be buying another turbo.

  • @Pr3vOne
    @Pr3vOne Před rokem +13

    The "stustustu" sound is the turbo still spinning forward and the blades chopping the compressed air. It's going to take a lot more than that to blow your turbo, and spin it backwards (turbos spin at insanely high rpm), it will put more wear on the bearing and such but isn't going to massively impact longevity. Compressor surge that is going to hurt your car badly is when your on boost and it starts doing the flutter sound, since your boosting more than the capabilities of the engine, it literally can't take the air being forced into the engine so the turbo starts surging.

  • @samisuhonen9815
    @samisuhonen9815 Před 12 dny

    The "stu-tu-tu-tu" flutter sound is actually caused by a lack of a BOV of any kind. It's caused by the throttle closing, and the pressurized air having no path to escape. So the air is escaping out of the intake, through the turbo the wrong way. And that causes the fluttering sound.
    You hear a "PSHHH" from a venting BOV, which vents the pressurized air out of the intake, so it doesn't wear out the turbo parts as it would normally escape out the wrong way through the turbo, putting high stress on the parts.
    And most stock turbo cars have a reciprocating BOV. This doesn't vent the air, instead it circulates it back in front of the turbo. The benefit of this system, is that you don't lose as much boost. These ones make only a tiny humming sound that's barely audible. Although a pro tip, is that you could replace often plastic stock intake tubing, with metallic (aluminum) tubing for like 300€, and the sound of the BOV circulating air will be MUCH more noticeable.
    Well, also if your car has a MAF sensor (mass airflow sensor), a venting BOV will cause issues with the engine. The sensor calculates air taken in by the intake, and calculates relative fuel amounts for combustion. These calculations will be WAY off, if you vent all the air as you lift off the throttle. The engine will run rich, run bad, may cause a knock, a check engine light, and might even begin to stall every time you lift off the throttle.
    A venting BOV is just fine and healthy if your car is tuned for it. Or if it is some kind of a model that has no MAF in the intake. Then you can vent all the air you want for loud hissing sounds. But for the love of god don't buy an Evo or WRX and just replace the perfectly fine silent stock BOV with a loud venting one. You will fuck up the tune. You will fuck up the engine. You will even lose power. All just to arguably make it sound a bit cooler.

    Years ago I had a roommate with an EJ20K swapped '00 2 5RS and he loved the turbo flutter sounds. I tried telling him that's air going the wrong direction through the intake pipe when boost is released but he didn't care. Then yesterday I see a video that was uploaded the same day, some guy with a Civic running ebay turbo parts and getting a dyno session done. All flutter lol. Then they start testing launch control settings and by the end of the video he'd busted a wastegate and cracked the manifold lol

    lol I upgraded my stock recirculating bov to a hks super ssq4 which is bent to atmosphere like people want. Also the loudness is more directly associated with the amount of boost your pushing. You can here it easily even when recirculating with a high boost pressure but it will be a bit louder if you chose to vent to atmosphere. Hks is the best in my opinion and don’t buy a knock off chances are you won’t hold boost correctly and your tune day will be a waste

      he explains it in the video. If you VTA on a MAF that has allready counted that air and delivered x amount of fuel . it will run rich af because the air that was supposed to be there just got yeeted to the atmosphere in stead of staying in the system to mix with fuel..
      You can VTA all day on speed density bc the metering of air isn't done on the turbo intake side. it's based on set VE tables and sensor outputs post turbo
      Likewise you can use a blow thru maf like a Maftranslator and VTA BC THE AIR IS METERED after the BOV's position in the charge pipe.

      @alyxryder1999 Před 22 dny

      -Stock Diverter/Recirculation Valve (Standard on most new turbo cars) = "Pwah" sound which is nearly imperceptible over engine noise and MIGHT be heard in cabin.
      -Upgraded Diverter/Recirculation Valve = "Psht" noise and can be heard more than stock, both inside and outside the car, but not as much as much as an atmospheric blow-off valve.
      -Blow-off valve = "Psst" noise and can definitely be heard outside of the car and, if you are pushing enough boost, there can even be a nice whistle tone at higher RPM.
      -Block-off/Delete Plate = "Stututu" noise and is very much noticeable, but you can run much richer and can run into something commonly known as compressor surge (read below).
      Best odds: Get a atmospheric blow-off valve adapter plate for your stock diverter valve (most cars turbo'd from factory have an option to purchase aftermarket adapters similar to this, usually around US$100). This will increase the noise produced from the turbo without running TOO rich (you will likely still run the tiniest bit richer than stock) or having to tune. I would not recommend block-off/delete plates, not because of compressor surge, but running too rich due to your car expecting air to recirculate through from the "front" of the turbo, which can cause some problems, such as spark plug and intake/exhaust valve pitting/fouling (simply put, damage), clogged fuel injectors, and rougher idle (which will cause problems faster than compressor surge).
      My OPINION on compressor surge (with operational knowledge of turbines/compressors within my occupation, I AM NOT AN EXPERT): Compressor Surge CAN be bad, but most smaller turbines engineered today have some sort of 'appreciable compressor surge factor' (per se) built into the engineering and production of the turbocharger itself. If you're running something older with a turbine made of ceramic or a weaker housing, it can be cause for early turbo failure, but that is only cause for concern if an ungodly amount of boost is being sent back into the turbine or running that way for an unreasonable amount of time. You're probably more likely (or just as likely) to MAYBE have your MAF or MAP sensor blowout of the intake, or, if running an intake manifold made of weaker material (such as plastic), you MIGHT crack the intake manifold due too much pressure beyond the throttle plate, but, again, highly, highly unlikely for both your sensors or manifold.
      Additionally, if you would like to hear your stock turbo system more than stock (in order from least expensive to most expensive):
      -Most cars turbo'd from factory come with a turbo muffler. You can get a turbo muffler delete for this which will add more of that turbo whine to your car's noise. (~US$100)
      -Look into an upgraded intake system and an upgraded turbo inlet pipe. This will allow the sound of the turbo to reverberate causing it to be "louder". (~US$500 for both)
      -Upgrading your downpipe (with a tune, chiptunes are sold for most cars now) and the rest of your exhaust system can cause your turbo to spool faster. (Varies, but usually ~US$2000 total)

    I've got a 2018 civic Si I put a HKS ssqv on, at times I would notice a sudden drop in rpms and a engine brake like effect after shifting with rev hang off ( no it's not the throttle padding ) while letting the clutch out into the new gear and it does it less with rev hang on, it's hard to explain what it was I experienced but I recently got a full recirculation BPV and I'm running that now and overall I would say the car feels alot " healthier " when shifting and going fast before with the hks it just didn't feel right driving

      Hey! You will have to contact your dealer to see if this is something that voids the warranty. In most cases does not but every warranty is different. Is it worth it is a hard question to answer. If you're going for a very modified car then yes, if you plan to keep it mostly stock then go with a recirculating bov!

    • @alyxryder1999
      @alyxryder1999 Před 22 dny

      -Stock Diverter/Recirculation Valve (Standard on most new turbo cars) = "Pwah" sound which is nearly imperceptible over engine noise and MIGHT be heard in cabin.
      -Upgraded Diverter/Recirculation Valve = "Psht" noise and can be heard more than stock, both inside and outside the car, but not as much as much as an atmospheric blow-off valve.
      -Blow-off valve = "Psst" noise and can definitely be heard outside of the car and, if you are pushing enough boost, there can even be a nice whistle tone at higher RPM.
      -Block-off/Delete Plate = "Stututu" noise and is very much noticeable, but you can run much richer and can run into something commonly known as compressor surge (read below).
      Best odds: Get a atmospheric blow-off valve adapter plate for your stock diverter valve (most cars turbo'd from factory have an option to purchase aftermarket adapters similar to this, usually around US$100). This will increase the noise produced from the turbo without running TOO rich (you will likely still run the tiniest bit richer than stock) or having to tune. I would not recommend block-off/delete plates, not because of compressor surge, but running too rich due to your car expecting air to recirculate through from the "front" of the turbo, which can cause some problems, such as spark plug and intake/exhaust valve pitting/fouling (simply put, damage), clogged fuel injectors, and rougher idle (which will cause problems faster than compressor surge).
      My OPINION on compressor surge (with operational knowledge of turbines/compressors within my occupation, I AM NOT AN EXPERT): Compressor Surge CAN be bad, but most smaller turbines engineered today have some sort of 'appreciable compressor surge factor' (per se) built into the engineering and production of the turbocharger itself. If you're running something older with a turbine made of ceramic or a weaker housing, it can be cause for early turbo failure, but that is only cause for concern if an ungodly amount of boost is being sent back into the turbine or running that way for an unreasonable amount of time. You're probably more likely (or just as likely) to MAYBE have your MAF or MAP sensor blowout of the intake, or, if running an intake manifold made of weaker material (such as plastic), you MIGHT crack the intake manifold due too much pressure beyond the throttle plate, but, again, highly, highly unlikely for both your sensors or manifold.
      Additionally, if you would like to hear your stock turbo system more than stock (in order from least expensive to most expensive):
      -Most cars turbo'd from factory come with a turbo muffler. You can get a turbo muffler delete for this which will add more of that turbo whine to your car's noise. (~US$100)
      -Look into an upgraded intake system and an upgraded turbo inlet pipe. This will allow the sound of the turbo to reverberate causing it to be "louder". (~US$500 for both)
      -Upgrading your downpipe (with a tune, chiptunes are sold for most cars now) and the rest of your exhaust system can cause your turbo to spool faster. (Varies, but usually ~US$2000 total)

    Blow off valves do three things. They don't kinda save your turbo they do. First they save the bearings from the surge spinning the turbo backwards almost instantly. Second they keep the compressor wheel spinning fast to increase transitional response on boost/off boost/ back on to boost as fast as possible. Third they sound pretty sweet but that's opinion.

    • @Evanmaier
      @Evanmaier Před 2 lety +10

      turbo flutter/surge doesnt spin the turbo backwards, it’s impossible, the turbine in boost is spinning at 10s of thousands of rpm, it is impossible to instantly just jump backwards, its just air getting pushed back through the turbine bits at a time, this is a huge misconception in the car community, not trying to argue or anything but just letting you know🤙🏼🤙🏼
