  • this is cool....totally and i researched what that filter did. i was gonna post sime dumb comment when, ur message popped up. lol

  • whers the speedup-o-meter?

  • i thought they only made alot of noise blowing off at higher rpms...?

    am i wrong? lol

  • @tyrannical @bikerboomer O.o Y'all make me feel dumb lol all this fancy car talk.

  • nice 10 second car :)

  • wind the boost up and it will sound better/louder

  • My friend has the grand touring version of the rx-8 without the navigation system. Nice vid though.

  • whats the 0-60 time?

  • It seems to me. The reason for, and or need for the filter. Is right after the BOV opens. It creates a vacuum inside it for a short time. Hence the need for the filter. Does that sound about right ?

  • You have the Speed8 spoiler on there? it looks like it hahah nice. :)

  • Nice!

  • The idea of a BOV or similar that goes 'psssh' on a turbo car is out dated and not good for your turbo or performance.

    It comes from the 1980s when racing cars with big turbos would dump the air from the turbo between gear changes (when the throttle is shut) to keep the turbo spinning and reduce lag. However, it's better to re-route that dumped air back to the intake side of the turbo as this provides even greater performance.

    It's for the sound only, anyone saying otherwise is selling them.

  • DONT listen 2 this guy A BOV is to release the pressure from the turbo when it needs it and that just so happen to be when the throttle shuts and by RECYCLING like u said yes push even more pressure on the turbo and makes Turbo Surge (when the pressure forces the air back out the turbo its self) and that makes the turbo fan spin the other way which is VERY VERY VERY BAD so if u wanna fuck up your turbo and your car at the same time by all means be a fuck face and do what this guy say

  • @makana931 haha you're an idiot. Next time read more carefully what I've typed and you won't look so dumb.

    Get a valve that recirculates the air, not one that goes 'psssh' and vents it to the atmosphere, just like I said.

  • DONT listen 2 this guy A BOV is to release the pressure from the turbo when it needs it and that just so happen to be when the throttle shuts and by RECYCLING like u said puts even more pressure on the turbo and makes Turbo Surge (when the pressure forces the air back out the turbo its self) and that makes the turbo fan spin the other way which is VERY VERY VERY BAD so if u wanna fuck up your turbo and your car at the same time by all means be a fuck face and do what this guy says

  • How many miles u get wit full tank??

  • nice car and sound !

  • you need to get some 285R18s on the back, and lower it. Handle the extra torque a lot better.

  • beefy little thing

    

  • very neat set up. thumbs up for u.

  • @SnowAura1337 Go to mazda's website 33k the r3 model, the sports model 27k and this engine is better than the rx7's engine because its a lot smoother, all its missin is a turbo >_>

  • so is this the sound that can be heard when import tuners shift

  • Lol that sounds like darth vader taking boost up his ass then exhaling

  • i am saving uo for a rx8 2010 and i plan on throwin a GReddy Mazda RX8 Turbo Kit w/ Intercooler and throwing performance parts like trubos and such will this make my gas mileage better or worse cuase i hav a 71 cutty and i put a eldebrock carb on and i get 160 miles to the tank and i want i car that i can make fast and still get awesome mileage

  • blow off sound 2:20

  • your BOV owned your camera

  • I've never heard of that, but it's brilliant! reduce turbo lag!

  • Sounds like a ninja farting. =]

  • ok where the fuck are u guys getting that a rx8 starts at 40k its called google use it before stating a idiotic remark about pricing i bought a brand new r3 which was 32k but bc it was last years model i got it for 28k so your fucking stupid

  • @SnowAura1337 The RX8 starts at about 27K

  • @SnowAura1337

    40k are you fucking nuts??? a new rx8 cost 26k the sport model and the r3 cost 32k wtf are you talking about. The rx7 cost 40k when it came out, jesus get your facts str8. And btw this engine is better than the rx7 engines.

  • whats the advantage or difference of one of these over a normal bov?

  • What is better the RX-8 or the RX-7?

  • @FFFFYourMom The 3rd gen Rx-7 (FD3s)  personally i like the 2nd gen Rx-7 (FC)TII

  • they really bark at over 22lbs

  • nice vid and nice car!

  • damn i got scared it looked like a scary movie at 2:22 lol i think you should go with the greddy type s bov it sound some much cleaner

  • Nice car man

  • what exhaust are you running? it sounds sick as hell

  • nice songs@!!!!

  • nice car. how much whp with the turbo?

  • perfect sound...damn cun....

  • id lol if he ran over his camera by accident

  • i actually like where the gauges are, the only thing i worry about is the engine man , i just raplaced 2 this week and last month i replaced 4 i hope it lasts long other than that it does sound very good .

  • that is cool as hell

  • what is a blow off valve cos ive never heard of it before?

  • sounds badass, good job.

  • that's what i call a motor!!!!!

  • nice car man but rx7 twin turbo with nitrous can beat sorry muahahahha

  • @SpartanVela7 your ignorant

  • Whats that gauge to the left of your greddy turbo one?

  • sounds awesome man!

  • @Soffex Nothing sucks about it. The gauges can be placed anywhere. I happen to have navigation system, so the usual center area is taken. There is an A piller option, but I liked it down on the steering area so you can't see anything from outside.

  • @tyrannical There is also a gauge pod for above the speed cluster

  • @tyrannical i agree it doesn't suck i think it looks cool!

  • @tyrannical thats actually my favorite location for mounting the gauges too

  • Rev it to 9k and u will hear ur BOV with the filter on, changing at 5k isnt going 2 set it off nice and loud.

  • nice dashboard

  • having the filter on there changes the pressure and is a terrible idea. it acts as a constant boost leak then... absolutely retarded.

  • @bikerboomer It's ironic that you're calling the BOV retarded since your comment is the only thing retarded. The car is MAP based not MAF, so it doesn't need to meter the air through the intake. Additionally the BOV seals shut when boost starts. That means anything above -10 inHg. Please read up on the Synchronic BOV before making yourself look silly. ktnx.

  • @tyrannical im not calling the BOV retarded, im calling the filter retarded. Now i did not know it was only MAP based and no longer usses a maf, so with that fact a vacuum leak wouldnt effect your fuel flow. So i guess it really does not matter, however most cars are not MAP based, so they could not use this bov.

  • @bikerboomer Ah ok - then I take that back :) MAF cars can use it. There is an "anti-stall" valve that prevents sucking in air in non boost situations.

  • @tyrannical oh really? i had no idea... hmm i guess i am the one thats retarded :P lawl. sorry bud! nice 8 btw, sounds good :)

  • @tyrannical

    Will this BOV be an advantage if I run it with a MAF if I recirc it?

    That is, will I still get the advantage of by passing the intercooler hosing while recircing?

    RB25DET btw.

  • @bikerboomer ok dude the synchronic sucks in air while accelerating to give the turbo time to get air to the engine so it dosent bog or give bad throttle response

  • Haha u let the camera alone:D

  • 1.3 litres of sexiness

  • nice sound when shitting!!! i just brought my rx8. and i trying to put some good stuff on it>

  • i have one on my skyline

  • No you dont your fucking like 10

  • lmao that kids an idiot

  • hahaha

  • @rinders11 n a sick way to blow ur engine mate. 25psi of boast on an eclipse... nice, man... it's gnna go boom sooner rather than later.

  • that rx-8 sounds really damn good tyrannical. I have one of those valves and I'm just doing the research.

  • I love how it sounds at 2:29 - 2:32

  • i think you should get a boost controller so that you can give it more boost you know

  • I have one. It's a GReddy profec B specII, mounted under the steering column.

  • so why do u need a filter over the bov again? i saw ur thing and went on the site but couldnt find why

  • No difference, had the bov on my Corolla recirc and vent to atmosphere, and removed entirely. No difference at all. Boost pressure was monitored via datalog on the ECU, not a damn difference.

  • clicked the wrong reply button, that comment was for nikzilla, about the recirculate.

  • @davidzzz94 maybe because this blow off valve remains open at idle,so the engine sucks air through it when its idling and unfiltered air isnt that good for your engine :D and i think the filter muffles the bovs sound a little? :) somebody tell me if im wrong :)

  • what does bloff off do

  • release the high pressure of the turbo when you throttle off

  • it releves presure from the turbo so its dosent hit the throle back plat when it closes

  • damn nice ride my boy has one like that except his is a lil louder but its still sick as fuck

  • how much horsepower do you have?

  • No time to explain the wankel engine look it up!!! Decide for yourself.

  • Hey is that available on a Miata

  • long live the turbo!!

  • Iv never had an rx7 or 8 but i keep getting told there slow, is this true? Apparently all the power is high revs but its only for a short amount of time?

  • RX's is not slow...

  • I've been told the same thing, only thing i know is the one i raced i beat and i only have I/H/E he was built and turboed, but come to find out he can't drive worth shit so i'm not sure. just my .02

  • @SuPrAmAd101

    uhm no they're not slow :p look around on youtube etc, the're not the fastest cars around but you do get what you're paying for :)

  • There not slow they just dont have alot torque.

  • RX-7 are not slow from stock, but RX-8s are consdered "slow" for a sports car. The main complaint with RX-8s is that they lack tourqe, but that problem can be solved by turbo charging it.

  • that sounds so nice and subtle compared to all of those other aftermarket bovs

  • lol. awesome at 2:24

  • yo props on the 8 it sounds sick as fuk im a seven fan myself but i apreciate a well done 8 is that the renesis engine or an rew

  • the car revs all the way to 9k so he probably has almost 20 boost total. i love the look and the way rx8 drives but thers not as muc htoys to play with under the hood you got a air intake ... turbo ...exhaust manifold? cat muffler tip thats about it right? dont turn this into a flame way i dont know much abotu the rotary engine

  • uh what? There's as many things on a rotary to mod as a piston car.

  • I wouldnt say as many.... I've owned 2 Rx7s before... and theres really not that much you can mod, its mostly tuning, your manifolds, injectors, ignition system, etc... internally they have no cams so to alter your "valve" timing you have to port the housings, also allowing more airflow in that youre making the holes biggers, etc... but theres REALLY not that much to mod internally on a rotary...

  • nice car!

  • boost 0.8??weak

  • You don't need as much boost on a high compression engine to make power. 9 psi = 300, 16 psi = 400 whp.

  • Awesome RX-8, nice job!

  • Do want

  • Wow, I don't think I have ever seen anyone do anything to a Mazda RX-8 and I lived in CA for a year. But I REALLY LOVE IT, it sounds amazing

  • TNX for answer my question & i' m gonna put a videomshowing my car later on ! ! ! TNX again

  • Hey i have a question i have a mazda 3 2004 stick shift 2.3 lts. & i want to know if i can install a BLOW OFF VALVE, all my engine is stock except the ecu system, i mean no turbo, no intercooler, can i install it without that ????????

  • is this possible if it is i will scream :D i want the hissing sound only :D

  • i want that too, i dnt wana buy a damn super charger!

  • exactly !!! dont have the money for a whole tune on the engine

  • u can install a blow off without turbo. the only prob is.......it wont do anything cause u dont need a blow off if u dont have a turbo xD

  • Without a turbo, there is nothing to "blow off". The turbo compresses air and forces it into the engine. The BOV releases that air so there isn't compressor surge (air pushing back against the turbo when the throttle body is closed)

  • Simple answer to dumb question, NO!

  • i believe BOV's are for turbo's only

  • @chekoeldisenador LMAO, a blowoff valve on a non turbo car

  • well every should!!

  • evreyone likes how blow off valve sound's like (at least i like it)

  • Why does it seem the only important thing to people is how the bov sounds?

  • is that a 13b or a 20b

    i dont really know the difference in appearence yet

  • 13-rew

  • rew?

    sorry im studying mechanics and im only just learning all this stuff

  • The new version of the rotary, the rotors look like alien technology

  • 20b has 3 rotors.

    13b has only 2.

  • sounds fricken sweet! exhaust is awesome

  • Sounds like Darth Vader "phhhhhh I am your father".

    But cool video(Y)

  • i like your video's

    Greats from Persia

  • thats FLIPPIN AWESOME :D

  • 1.3 rotor...

  • what is the right extra gauge for ?

  • You mean the one on the right? Shows the air/fuel mixture. I don`t know much but if I remember correctly 13.5 was the optimum mixture

  • thanks man

  • 14.7:1 is ideal according to my labs at school, but leaning out the mixture a bit makes it burn better on turbos

  • LOL your nuts. Turbo cars run richer than that, thats ideal as you said. If you ran that your car would go boom.

  • hahaha LMAO yeah if burn better you mean burn holes in the pistons better!!!

    hicher is better on turbo cars to preven detonation. LOL

  • HAHA LMAO you know nothing about fuel.

    higher octane reduces the chance of detonation NOT how much fuel the injectors dump into the cylinder. SO HAHAHAH to you when you blow your fucking motor

  • we are not talking about octane genius, we are talking about AFR, leaner than stoich can cause detonation not higher.

  • alright, i'm done arguing with you idiots.

    go run a rich-er mixture with your regular octane gas and blow your motor to fresh hell because you think that MORE of that weak ass fuel is gonna save your motor

  • Well less of that "weak ass fuel isn't going to help.

    The point that most are trying to make (I think) is that it is safer to run a LITTLE rich so that in the event of a boost spike, sticking waste gate, BOV, etc there is a bit of scope for saving the engine.

  • @KtfoMustang, everyone here is correct but you. 14.7 afr is technically "ideal", but you cannot use it in FI as it would blow the engine. Thus you will usually only see 14.7 at idle, and closed loop cruising. Any WOT activity will involve a richer mix. Somewhere around 12.5 is usually the target for boosting, you can go leaner if you have solid fuel, but people usually want a little buffer from the bleeding edge because things can and do go wrong.

  • i truly hope no one listened to your advice. 14.7:1 AFR is a lean cruise. you need to aim for 12.1:1 AFR at WOT to reduce chances of knock/det.

  • Especially in a rotor.

  • Comment removed

  • did u do the research? because you are completely wrong. please lets see your turbo set-up.

  • Comment removed

  • Rather not take the risk in a Rotor.

    They are very sensitive to detonation and if you get a big lean out you don't usually get a second chance. I got lucky on one occasion when new to Rotors.

    Like I said, rather not take the chance, better to be safe than rebuilding.

  • that isnt a turbo tho right so why the blow off valve

  • did u not see the turbo gauge? lol fail

  • Wow you guys can't see the turbocharger at the begining of this vid, and can't hear it throughout. No shit, that's a boost gauge, and that one on the right is the voltmeter.

  • You're an idiot.

  • wheres the wicked sick burnout or drift? i mean cmon somthing your puttin a camra outside the car take action of that shit man

  • the reason they fit it with an air filter, it's always open and allowing air to get sucked in, or escape. There is zero chance of getting compressor surge. The BOV operates on the reverse of a standard BOV. It's always open, and only seals when there's enough pressure to force it shut.

  • what's that gauge on the right that shows 10-17? is that a voltmeter perhaps?

  • that would be a wideband. shows the air/fuel ratio.

  • Kör som en kärring!

  • thats a nice dude. it seems to be powerfull but. beat it!! then we will see the real use of these sweet accessories lol

  • yo

    haha i like your little nota on were not to put dick head comments lol but yeah that car is bad ass

  • Sexy. But pitty rotaries requires frequent rebuilds. Of course, depending on how you drive it :)

  • This isn't the RX-7. The engine in NA form can go over 150k miles no problem (We don't have a ton of data yet since the car was only released in 2004), but the early ones had issues because the OMP was not flowing enough oil, which caused engine damage over time. Since been fixed, so no reason for them not to go to 200k if maintained.

  • rotary engines make me all tingly inside :D

  • I just wish they got better MPG's :'(

    Can I put this engine in a wheel barrow?

  • guess you don't need any more than 9 lbs when the motor turns 9000 w/o a problem lol

    sounds good

  • i have a hks ssq and its very loud and sensitive, i dont like yours as its not that loud,maybe more efficient but i pay more for the noise im afraid,it looks good with the filter on it,what does your car rev to anyway,they rev high as standard so im just curious

  • only nine psi?

  • high compression motor. no need for massive psi.

  • LOL at coming back and just reving ur engine haha

  • that sound makes my ears have orgasms lmao

  • dud ur only running 10lb u don't really need a bov, fiswill is rite only unwanted pressure

  • bad ass sounds great!

  • weld er up let the boost build till the engine blows who needs a blow off

  • your thinking of a wastegate.... a BOV does not control boost, just un wanted pressure built up between shifts.

  • your right my bad i had the wrong thing in my mind. i know all the parts and what they do i just mix things up at times

  • hey i nevr knew wat those flashing numbers were. wat are they?????

  • PSI is basically how compressed the air is in the piston.. higher, more power, faster engine wears off.

  • it would have been funny if u hit the cam and funnier for what

    QuantumCarl said

  • how much does that car wiegh stock?

  • It depends on package level, how much gas is in the car, driver weight, etc. But generally speaking, it's around 3000 lbs. If you strip it down you can go to 2800 lbs without a lot of trouble.

  • thats wierd bro but i hurd the rotary engine is lighter then a piston engine

  • it really weighs that much? thats seems high since the motor weighs nothing lol i guess its all in the frame, i know they had a hard time keeping it stable with the rear doors. i really would have thought they where lighter. i have a gto and i always thought it was really heave but it wieghs about 3700. its a sick car though man. ill have one some day:)

  • around 1300kg

  • I'd laugh so hard if someone made off with your camera.

  • only 9 psi?
