Synchronic BOV on Turbo RX-8, part 2

[itzAndyBeezy]

Shit looks like its gonna punch through a vagina.

[adztermancoool]

LOL "whi-psh!"

[sharrukhahmed]

hahahahhahaha.....

[bigbocceball]

Where's a good place to get a turbo?



[abdulios]

@bigbocceball Go to your local race store, i don't know what else to call them. Or buy a quality turbocharger online. Garrett makes good turbochargers. But I'm sorry to say your question is a little stupid. If you were serious about purchasing a turbo for your car then you would not ask on a video such as this, you would (should) research it yourself.

[KnightKadir]

nice car

[pbcms13]

sounds like a whiplash

[RodanMz3]

lol would have been funny if you ran over ur camera... :) kool vid

[dontrustwhiteyever1]

Yes thus the term Blow "off" valave and not blow "in" valve!!

[THACHACHA]

hey bro i jus got done turboing my car n welll i was wondering do those gauges bother u while driving as in r they in the way... do they block alot ..???? oh n btw how much whp u makng at how my psi

[phuckthis343]

I have the same battery =] OPTIMA is FTW

[WeLoveBud]

Hey im interested in buying an rx8 but i dont know how well they run or if they break down often got any tips or suggestions? Any and all thoughts will be accepted thanks you =]

[g4m3rsc0r3]

what if MAF and MAP. also i have never known of a BOV to SUCK air back into the engine

[guccamain]

@g4m3rsc0r3 the synchronic does watch the vids about it, it sucks in air to give u a better throttle responce so the turbo has more time to get air to the engine

[tevinm14]

that makes the car sound like a fucking monster having sex with an even bigger monster...its like mmmmmmmmmAAAAAAAAAAHHHHHHHHHHH mmmmAAAHHHHHHHH lol

[RainingSushi]

uninteresting blow off sound but I love the fact of how it doesn't mess turbo set ups!

[quadracer111]

Cool video and sick rx8.

I have a r32 gts-t skyline, It has a synapse currently installed. The skyline has a maf, it is currently recirculating, I want it to be louder so I need to vent it to atmosphere. Can I take off the recirc hoses and install the anti stall kit?

Thanks

[dimitrya1234]

nice

[joshtard1111]

Hey I have had my RX-8 for a couple months now and i've been thinking about making it turbo. There seems to be no room in the engine compartment so what exactly do you get rid of? Is it just the stock airfilter? And i also saw a supercharged RX-8. Which system seems to work better Turbo or supercharged? Thanks

[DeMoeAurelius]

@joshtard1111 Depends on what feeling you want for your car Supercharged it belt driven so power is always there via belts!!! Turbo you have wait on spool up and your good but watch it cause RPM climbs fast. With turbo worry about boost creep, spikes, and excessive heat. With super charging worry about spinning belts off (rare but seen it happen few times) and limits of the pulley...

[Fubar231]

Hey man, the problem with bov's isnt that its sucking in unmetered air, its cause its releasing metered air, therefor causing a rich condition, not the other way around.

Its releasing too much air, making the car with, more gas less air = rich, bov's release air, not suck it in.

[tyrannical]

@Fubar231 The Synchronic without the anti stall fitting is OPEN when there is no boost. Thus it is sucking in unmetered air, and why a filter is required on the BOV. This is not an issue if you have a MAP based fuel system, as shown in the video. You obviously would not want this setup on a MAF system.

[unyosi]

@tyrannical if your sucking past the bov you have a poorly matched turbo all bov are open at idle or whenever there is vac in the intake ie when the throttle blade is shut allowing boost to flow out throught the bov only time the bov is fully closed 0 vac

[tkwjh07]

@tyrannical unless your doing a blow through setup



[urbex2007]

@Fubar231 he still doesn't know what a BOV is so i wouldn't waste your time!

[warrantofficerliu]

@Fubar231 it all depends on if the car is using a maf or map , lost of new cars now are sticking with map as its more accurate interms of lag time between the ecu and the change on throttle.

[godverdomme66]

dude sooo niceeeee!!!!

[chivabh]

hey dude.. you should make like a race.. or something like that.

or make a video where you go fast or stuff... i also have an rx8 but its stock.. i might install a turbo on it.. but later

[alwaysanthony]

....mysql....you're bov is just sick

[MrMetalord]

sweet!

[lzhmax]

it sounds awesome man!

[DSMDriver69]

haha i dont know what it is but watching tha bov makes me laugh. it does sound good though

[kevin28800]

that car sounds amazing

[georgekenedy]

whats the name of the blow of valve? :)

[sc1zzen]

your videos are the sole reason I will have an r-x8. Im thinking after I get threw my first 2 years a Florida State College. I hope to see tons of new vids and ideas, so I will know what and what not to do!

[tyrannical]

rx8 has high compression rotors, so it doesn't need a lot of pressure to make power. The general rule of thumb though is 9 psi = 300 whp, 16 psi = 400 whp.

[Inklebonker1]

@tyrannical excuse me but what is all that?

i dont really know too much about tunners (muscle car guy) especially rotorys but i just love them.

[MonteLSV6]

It's a turbo set up. What you were looking at in the beginning of the video you were looking at the BOV (Blow Off Valve) and the charge piping on the cold side that goes into the throttlebody.

[opiumrx]

well it could if everything is done wrong and its not prepared to handle that kind of boost.

[Samtkjones]

0.9 bar thats like 13psi isnt it

it depends on the engine but my mate ran his standard gt starlet on 14 psi which is just under 1 bar for a long time and the engine never blow up

[apolomoon33]

its not true that if you go over 13psi your engine will explode. i've seen cars with over 20 psi. there's a DSM eclipse with either 23 or 24 psi. you can find it if you look for it on youtube

[Samtkjones]

bov stands for blow of valve it releases pressure built up by the turbo when the throttle is let of, because there is no where else for the pressure to go but back out through the turbo, unless you have a bov

[apolomoon33]

stop being a fag. i asked a question, you dont like it gtfo and dont answer with some stupider shit.

[apolomoon33]

i know this sounds really stupid....but can you put a BOV on an automatic?

[hurcorh]

yah, but it needs a turbo.....

[opiumrx]

yes but why would you want to do that?

[apolomoon33]

maybe i want to, got something against it?

[opiumrx]

not but theres really no point to it besides the fact you could show off

[apolomoon33]

im not putting to show off. i love that noise and to me i dont really care about what people think.

[150Spoke9]

This is not Intended for Women to Watch or they might faint from too much Visual Excitement!.................Pa­rental Guidance is highly suggested.............Rated P.G.- A.H.J.

When did they come out with that "whatyuhmacallit" known as "Synchronic B.O.V."?

Which Manufacturer and Model # and is this the only company that makes this style of an Blowout Valve?

Nine9eniN

[seboll16]

perfect sound,

[GreenBeret77]

Sounds really good bro... I like what you've done so far

[hellsingorg2]

whats the gas millage like with the blow off on?

[tyrannical]

The BOV has no effect on fuel economy.

[djarti24]

hahahahahaha this is porno ,i,

[silntinsnty]

niiiiiiice..

[sayayinep3]

yeah i love that BOV is slepeer i had mine like 2 years and still works good

[360mmspider]

does anyone know if mazda changed there engine alot in the 09s i would like to know if i can put rx8 parts that were for the 08s in a 09 ,will work ?

[DecalfxVideos]

Same setup

[tyrannical]

depends on the part. the 04-08's are interchangable. The 09's have some slight modifications, but it's changed enough that you can't use the same rotor housings, tail lights, bumpers, etc.

[360mmspider]

do you know if a 08 mazdaspeed exhaust or mazdaspeed intake will work with my 09 ?

[Rabbiaodio88]

farting mazda

[hellriser180]

0:16 looks fucking pissed lmfao

[ianakabeans]

y not filter the BOV? its Blowing cleaner air right into the engine compartment, which in turn may contribute a small amount of clean air back into the engine

[Totenhosen17]

uh, why would you filter the air coming out of the turbo? Theres already a filter on the turbo... :O

[bmxking2008]

its probs to make it look betta nd shinyer under the hood

[CharlieF576]

This remains in option position at idle, so it's sucking in air (bypassing the turbo system). There r three options: 1) to install a small air filter on it, 2) recirculate the bov, or 3) install the anti stall adapter.(shown at the begining of the video)

[Totenhosen17]

Watching the vid more carefully i see what your saying.

Thanks! :)

[CharlieF576]

your welcome

[supradave9]

what does the anti stall adapter do? i cant read it in the video, the letters are white aginst his silver engine parts

[tyrannical]

anti stall is for cars with maf and can't allow air to be sucked in via the bov.

[supradave9]

oh, but how does that help with lag?

[texcali85]

shit.... damn thing sounds like an airliner... prolly got some balls. how much power you think u got? im not too much into imports but i do have great respect for em.. ima a dodge man myself got a 01 cummins turbo diesel 4 wheel drive with a dayna 80 rear end axle.

[Brammage]

I'm not 100% sure I get the purpose of the filter on the BOV. Typically if you vent to atmosphere the air never reenters the system anyhow. Why filter the air as it's being blow out of the system? I could be missing something here. I read the manual for that BOV and according to the manual a filter is required. Recirculation is usually done through a tube that just pushes the air back into the system without exposing it to unfiltered air. If there is something I don't understand please inform me

[texcali85]

heh yah bro i agree with u on this one, no need for a filter unless he some how wants to make cleaner air for our planet hahaha

[CIDVICIOUS831]

dont really like the sound. im more in to the sound of a trans am ws6 with flowmasters

[trakasubmersis]

wooow, i really liked it

[Sebastian3103]

lol like a hairdryer!

[Amypr1ncess]

proper care? proper care for a rotor means thrashing it. u dont know shit, just continuing a fight.

if arguing over the internet is pointless, why did you reply?

what we have here is a keyboard warrior mascarading as fucking dr phil.

If you reply, ur proving my point. And as i know you will, ill be busy 'getting a life' as ur next message appears so i apologise for no reply.

In the meantime, look up 'internal combustion for dummies'. and the secrets to direct exhaust injection. :P

[fcazares583]

stupid asses. y argue over the internet....fucking shit talkers

[Amypr1ncess]

y comment on shit talkers over the internet? fucking shit talker about shit talkers.

[mechaniclad128]

HAHAHAHAHAH MADE ME LAUGH :):):)

[spsickfastsupra]

"what is this whole idea of unreliability past a certain mileage.. it doesn't work like that all it is is a myth."

Well buddy it didn't seem that way with the rx7's the only thing reliable about them is that they DO blow up after x miles. What you said there, is like saying the 2nd gen 2.0L eclipse turbos crank walk is a myth lol.. of course your correct when talking about "rotartys" in general, but not Mazda and their rx7's

ps. this bov looks like sum kinda ant eater w/ that thing on it

[cabras51]

nice sound!

[Amypr1ncess]

is this engine still alive? no rebuilds? how many kms? i hope so, at least one turbo rx8 should have lasted more than 20,000kms..pls say it is. plus, what mods do you have?

[bokyboy123]

LOL?

Rx-8's can easily out-live a piston engine

what is this whole idea of unreliability past a certain mileage.... it doesn't work like that all it is is a myth..

rotaries can easily make out past 200,000 without issues as long as they are maintained properly.

[Amypr1ncess]

are you so stupid that you didnt notice this rx8 has a turbo on it? and that turbos mean the engine doesnt have the same reliability as they do n/a?

[bokyboy123]

nah man

you are mad retarded

turbo doesn't effect the wankel's life as much as you think....

infact there was someone in the US who made 450,000 miles on a 13b turbocharged stock.

fucking idiot

[Amypr1ncess]

prob an rx7 13b not a renesis. ur a moron. if all the evidence youve got is 'some guy', and ignoring every1 else on here thats had their bolt-ons blow, by all means push 12psi into a stock renesis. in fact, if ur so confident, y dont u do it urself and prove me wrong huh?

[bokyboy123]

LOL PROVES HOW MUCH YOU KNOW

THE RENESIS IS A REVISED VERSION OF THE 13B WITHOUT A TURBOCHARGER AND LARGER ENGINE INTERNALS RESULTING IN MORE NATURALLY ASPIRATED POWER

By all means add a turbo charger to the renesis and it would be very similar to the 13b in a 7 series.

[Amypr1ncess]

the 13b-renesis is nothing like the 13b-rew. i think the side exhaust ports (rather than peripherals), 6-port design, and of air jets, exhaust air pump and overlap together arent in favour of forced induction, not to mention loads of arf rich/ detonation problems without an efi. mazda themselves have struggled with turbo-charging the renesis. but its kool if you dont believe me, one day ull get ur proof and rub it in my face eh?

[element774]

both of you bitches stfu...a rotary is just that..a different type of motor...both piston and rotary engines can run well past their intended use with regular care......

adding a turbo to an otherwise naturally aspirated engine will ALWAYS decrease its life, and can be very unpredictable........that is an inarguable fact.

Now, let it be learned....arguing on the internet is pointless.

[Amypr1ncess]

a 'different type of motor', in what way? do u even know why its different or the discrete differences/problems with turbocharging either are?

You obviously havnt noticed that neither of us have sent anything lately because we're done jackass. Ur participating in and essentially, re-igniting an argument that had ended, So before you go flaming all high and mighty like ur god's fucking gift to this convo, have a check and notice ur a Hypocritic f**ktard.

k?

[texcali85]

Ahahaha damn bro u crack me up. hells ya tell that fcazares583 fucker whos boss. you should keep writing shit to piss em off even more. you make good points though man, you make good points...

[Amypr1ncess]

lol, u just added that last part so i dont go flaming to you 2...just looking back at it, i went nuts haha. I promise to keep pissing people off ;)

[BOOSTBUGGED]

@bokyboy123 and piston engines can make it out past 400,000 kms...

[catfisher10100]

@bokyboy123 I wish i could give you 1k thumbs up.

[ZoinkyFilms]

@bokyboy123 my mommy's toyota avalan has 300,000+ miles.

[rachaeljanenz]

Looks like penis.

[aicrag1]

DAM!!

[gooferman609]

so would you recomend no antistall device or BOV with antistall AWSOME SOUND! amazing car man!

[rondar2]

sounds like a whip

very cool

[tyrannical]

how would a bov without a turbo give you any gain? the bov itself doesn't give you gains even with a turbo. All it does is lower spool time between shifts and prevent backpressure on the turbo.

[1chavito3]

oh oky just woundering

[SeigiSama]

ya you really don't want 10+ psi over 1 atmosphere slamming into your butterfly valve when you let of the throttle to shift gears. Charge pipe blowing off is not a good thing.

[tdog4500]

actually changing the bov can improve hp from other ones, i saw a dyno of a twin turbo vet that had changed to synchronic bov's and gained about 15-24hp thats quite a big dif for just switchin a bov! but without a turbo..ive never heard of even doing that that seems stupid

[batmanrosel]

i'm hooked, going o/s soon, but as soon as i get back i'm buying an RX8, boosting it and buying one of those bad boys!

[eclipse93gst]

be honest with me bro im upgrading my dsm soon working 400 hp to the wheels and i dont want a shitty bov but there is so many choices and so many opinions, and by the way it looks like u know alot about this bov so what is your opinion between this bov and hks and tial 50 mm let me know whats up thanks by the way bad ass rx8 my buddy has one the handling is fucking awesome mazda new what they were doing with this car

[kingtubenino]

but the synchronic bov sounds so nice tho. ommggg

[kingtubenino]

SOUNDS LIKE A FUCKING CANNON HOLY SHIT

[KapteinOpel]

But what is the point of a BOV anyway?From what Ive been told,it is supposed to reduce turbo lag since the compressed air inside will slow the turbo down unless its released by the BOV..My theory is that it in a such case it would be better to put on a butterfly valve BEFORE the turbo,that acts like the BOV,only it shuts the air off rather than releasing the excess.Think of a clogged vacuum cleaner,the motor spins faster because theres no air inside that slows the fan blades down.Just a thought.

[Samtkjones]

how do you mean before the turbo?

[KapteinOpel]

I thought the very point of a synchronic BOV was to suck in air...wouldnt it be better to couple it to the intake hose between the turbo and the air amount meter?

[tyrannical]

There is more than one way to use it. Recirculation is useful for MAF setups. You don't need it if you're running MAP. I happen to have the choice between the two using a microtech and an accessport.

[bboipoet]

beutiful..just beutiful

[tonysam11290]

its beautiful, nice try... i need one of those on my rx :-)

[blackshadow9115]

cool :)

[roddymerritt]

Nice!!!

[nissanshift20]

that bov sounds awesome, and the rx8 sounds even better!!

[AkinaGod]

How much torque does this one have?

[tyrannical]

210 on the greddy turbo at 9 psi. 250 tq on the 3071R upgrade at 9 psi. These are all low boost numbers, we can go to around 13-14 psi on street gas.

[AkinaGod]

Not bad. Not a fan of greddy personally. 250 torque is good though. What is the HP at 250 torque?

[tyrannical]

greddy can't make 250. greddy makes 270whp/215 tq at 9 psi. To get 250 you'd need something like a 3071R, and it makes about 308 whp at that torque level (also 9 psi). If you go to 16 psi, you'll make 400 whp / 300 torque.

[zack199421]

you know your shit nice dude!

[rockyandcrystal]

i need to know where you got this filter. I have the same bov and can't find it anywhere.

[nebuthet]

hey dude i have an rx-8 and ive always wanted to turbo it....wat would be the best way to start this?? is it costly and wat sort of power gain will i get from it??

thanks

[franky2me]

fuuuuuuuuucccccccckkkkkkennnnn­nnn nice i want one now

[650FLN]

since you posted this video two years ago, how has the whole system held up?

[tyrannical]

I joined 2 years ago, the synchronic hasn't been out 2 years yet... but if you're talking about the rx-8, it's held up well. The accessport is a godsend for the vehicle. Perfect fuel management without it doing odd things due to temp changes, or pcm fighting with aftermarket piggybacks.

[650FLN]

What ECU have you got for it now to run that system? I want to get a turbo for my RX8 and want everything to run as nicely as possible with very few bugs. Do you expect the engine to hold up well running boost?

[dejacky]

What brand and model air filter is on the blow off valve? I need to get one for my Sychronic bov and yours looks good!

[TonyT397]

what type of turbo kit you running and what are your horsepower readings???????

[tyrannical]

280 whp right now. In 2 weeks I'll be upgrading the turbo. So will be able to push 350 whp.

[TonyT397]

you still did not tell me what type of turbo kit your are running on your rx8??

[hish911]

what turbo kit do you plan to get

[ggod408]

It's not often you see an RX-8 with a turbo. Very nice!

[Bartolini87]

like the car, watched both vids. like to see more action :)

[tyrannical]

After a few weeks with this BOV, the only issues I've had is that the o-ring that seals the BOV to the flange is easily cut when installing ... so you might want to get some extra when ordering. Also the two set screws that hold the BOV to the flange can work loose. Get loctite so they don't fall out. Additionally, the set screws are kinda soft and can strip if you tighten too much.

[xcincai]

excuse..

btw wat is the anti stall for??

[blackXSpr]

anti-stall

figure it out yourself

[crswjr]

Isn't it to minimize Turbo lag?

[kornukaz]

Nope. It's for the car not to stall at idle or intersection lights etc.

[mzking1980]

where can i get one of those filters?

[tyrannical]

Email Geoff at titanmotorsports dot com. He has the best price for this BOV.

[mzking1980]

i love the sound..i cant wait to get mine..on order now.

[tyrannical]

It's one or the other. You either have the recirculating fitting (with filter over it) or the anti stall valve.

[staticlag]

so, the antistall valve was on under the air filter?
