knowledge is power, 18lbs of boost is power also.

Life starts at 30+ psi

tpumpiscmibicv For race cars and weekend warriors..yes. For daily drivers..it won't be driving daily for long.

[@TreVox]

tpumpiscmibicv You life will end very easily if you're not careful..

[@joshAKAtheman]

Running rich between gear changes? Popping flames while shifting? YES!!!

[@Rusty_Shackleford79]

“Spirited driving” - I’ll be using that 😂

[@mozzy4637]

Bov--- wooommmm pshhhhhhhhh Recirc-- woooommmmm pshtututu 👌🏻

[@Th3Acc0mplice]

Mozzy 46 Summed the video up in 2 quick lines 👍🤣

[@atlanticimports6939]

Nice thing about the greddy type s you can make it recirc just by attaching the bypass hose to it. Just need a sti-greddy adapter plate and on hose 1.25"ID slightly longer than the oem one.

[@blakeslater1139]

Straight to the point, nicely done.

[@juancastillo5078]

Thanks man, what a great video. I can't tell you enough how many bad videos I have seen over the years. This was clear, concise and very informative. You earned my sub and its no wonder why you have 72k subs. Keep up the good work.

[@Bychugoodmoe]

Straight to the point 🔥💯

[@SchaferTheRicer]

FINALLY SUBARU LOVE

[@davistarwin3871]

I'm french but your explanation is easy to understand, good job, thanks !

[@jessereeser3376]

Great video! Got to the point without excessive nonsense in between.

[@Rekkless]

I would like to Add that a recirculating valve sounds better too. I've got BOV on my S15 that can be adjusted to full recirculating and full atmospheric (GFB Stealth FX Bov) and I vastly prefer the sound of 100% recirculating vs 100% or even 50% vent to atmosphere. Granted not all turbo charged car will sound the same as the SR20DET has a long venting pipe and mine is fitted with a POD filter which does make the vent sound louder.

[@troopznz1029]

wish i had seen this video earlier on my subaru had the same problem now changed to recirculating bov

[@pashagandomcar4882]

What a wicked video! No nonsense! Well explained 👏🏻👌🏼

[@Shatteredworld]

o -o i wasn't aware of these things. It the minor things that make car knowledge amazing. Thanks for the info guys!

[@kornshadow097]

So why does the rich condition matter? If it's only on boost and between shifts anyway? Wouldn't the extra fuel help turbo spool stay up due to unburned fuel traveling through the exhaust and turbo?..

[@brideau22]

Would you recommend a recirculating blow off valve for 2003 Lincoln LS turbo? Tial 50mm Qr? Using precision 46 mm wastegate.

[@shortyboy1986]

Good video

[@SharpyBoy221]

Should have said, "recirculates air before turbo". The air it is recirculating is already pre-intake manifold.

[@hurley566]

another great video! Do either of the valves offer more performance than the other in terms of boost produced? Or are they simply used depending on where the air meter is located?

[@BJWL93]

0:33 the turban blade?

[@Ra5caL06]

Wow I just learned something new. On a turbo Brz should I use a recirculating valve or blowoff valve?

[@briguy91931]

Subaru, porsche, the old VW water boxer, all are amazing designs! Lol although I dont especially like the new wrx

[@ANCIENTASTRONAUT]

i too also do some "spirited" driving

[@Scrrumy]

so for a gen2 speed3 im not sure if i want to get a bpv or a bov. having the pshh sound is always nice but im not sure what is more efficient for the car on its stock tune. If the valve is after the meter then id be better off just getting an upgrade bpv and not a bov. but if not...

[@adamzebrowski1459]

very informative and to the point vid. thanks for sharing!

[@alexhsu190]

Is it possible to do a hybrid of an anti-lag system and blow-off valve? Such as placing the BOV before the mass air-flow meter and venting it to the section of exhaust before the turbochargers exhaust wheel and after the engine?

[@darrensowden4178]

Excellent advice, thanks

[@jorgehernandez4283]

what would i need to do, if i wanna install HKS BOV on my 2015 subaru sti?

[@logicalpancake1347]

Turban blades.

[@alexmoore5970]

What sensor does the FRS have? Is it a mass air meter or a MAF?

[@hutchinsonshaun]

That andy, was a good explaination. thank you.

[@julianp9107]

is there a video about Nitrous Oxide? Preferably one talking about how much of a shot is good without ruining your engine

[@12389h]

Depends on what engine you're running.

[@bobbyching7502]

Does recirculating values make the same noise as the blow off values? I have a 2013 mini cooper S hardtop, which one is more suitable for it? I will have it tuned with the installation. But which one will produce the releasing air sound while releasing the pedal?

[@billyb7561]

Perfect.

[@ryanfitzgerald385]

What do u mean by tune? I have installed a intake looking into bov or recirc but not many made for 2011 rdx i found a turboxs hybrid on ur site would u recomend that ?

[@shahilpradipkumar1387]

Which type would be better for mk4 golf 1.8t?

[@robertt6430]

Nice

[@bigmotoxer]

But if the MAF is after the BOV? ...would it even matter if VTA, or Recalculate? You didn't address this Andy.

[@kyle-kelliher]

so the next question is how would you be able to to run a BOV on this car properly?

[@Truepk]

***** why would you need a tune for a BOV.

[@zkelley98323256]

Robert Campbell because if you are switching from a diverter(recipricating) valve to a blow off valve the car is now venting the extra air into the atmosphere instead of back into the intake. so the car may think that there is a intake leak of some sort and throw a "check engine" light. tuning will then fix the car's computer to know that the air is being vented out instead of reused.

[@carerragted8145]

you would have to run a MAFless setup...

[@briguy91931]

Who actually completely lifts off the throttle when driving "spiritedly". Lift a little, but not all the way! Lol whenever you change the blow off valve or recirculating valve you should get the engine tuned for it yes?

[@TheMiza555]

if the bov or recirculating valve is the same (upgrade bov for bov, and recirculating for recirculating) you shouldn't need a new tune, but if you go vise vera you will if you have a mass airflow sensor set up, with map sensors its all about pressure at any given point in time and it doesn't matter where the air goes to and from where because your going by pressure and temp not volume

[@SycoActiveMinds]

Wen u say tune wat do u mean

[@joule2104]

Hi, I'm trying to get information before adding a BPV to my CLA 45 (no BOV or BPV from stock). If I add a BPV, is the air being recirculated back to the manifold will disturb what's calculated by the mass air meter?

[@kbleik]

Would running rich basicly harm my audi tt 2000 if i switch to HKS blow off valve?

[@pebblez_]

nice

[@ahmidra8671]

I have an 05 impreza rs 2.5 with a brand new top mount intercooler ..does it have to have a turbo in order to install a recirculation valve???

[@theagemon5]

awsome! :)

[@lucywucyyy]

if it doesnt make a fun noise im not interested...

[@nicholasmazzella136]

or get an ecu tune

[@boostfiend]

YOUR MUSIC IS THIS LOUD... you are this quiet.
