Synapse BOV vs. HKS

[ClubbySuperCharged]

Anything wrong with an auto?

[marcelfast1]

HKS forever xD nice video!

[Brunopod4]

What the hell is this.



[delsurway]

HKS

[Smylyn2jz]

any reason for the dyno comparison for the bov's?

[bpetrach1]

*turbos

[bpetrach1]

Who turnkey an auto. That would explain the flutter problem.

[csrt4life]

so what kind of power numbers did you put down?????doesn't seem 3/400 hp...but nice build either way.....i currently run an hks v3 and have flutter only under low boost conditions..maybe 3 psi or so....

[dddecarmo]

that bodykit and tubo aint on an automatic..... should of been a 5 spd

[Pamfilo22]

I dont understand how people like to hate on other people's cars I wonder do they even have a car of their own? And also a prius that does not count. Also Nice Scion Tc :)

[T5SG]

@Pamfilo22 so right dude, they would never say shit to him in person

[Necraeon]

5:17 or so, it looks like a dick. How lame is that.

[southernclassik]

what is so wrong with an auto. If thats what someone wants to spend their money on, I think thats their decision... smh

[ActionBasterd630]

it sounds really bad tho listen to it lol

[shizzel122]

sounds like a piece of rice

[ReptarGSR]

"PrestigeWorldwide" hahaha

[22bgc8]

good lookin tc, but an auto.... thats a buzzkill

[UNOHsupra]

Hey, hate to break it to you, but with that synapse bov.....the pull you did showed really bad surge dude. I dont even have to look at the compressor wheel to know, the engine showed true comp surge. I have owned plenty of good and bad bovs. That flutter you are getting isnt true compressor surge. The flutter is caused by the valve in the bov not opening completely or at all on the "hks" bov.

[nikolaiski]

ATTN. VIDEO POSTER:

How many bar of boost and what turbo was your car running on and what were the power figures after tuning?

There seems to be a correlation between lower boost automatics running MAF sensors and compressor flutter - the stock springs are always too strong...problems usually solved with a plumb back bypass valve. True with most sport compact automatics running light pressure turbos factory-stock.

[OperationScion]

I have a Dezod S2 Turbo Kit with the exact same BOV and i dont have this problem what so ever. Besides thats not even true compressor surge, its turbo flutter.

[rx7kidd13]

@OperationScion whitch is the beginning of compressor surge, the bov is improperly tuned for the set up

[OperationScion]

Agreed. Mine works just fine. I have next to zero flutter, not nearly as much as you have with the HKS. Also I didnt mean to post my last comment more then once.

[OperationScion]

I have a Dezod S2 Turbo Kit with the exact same BOV and i dont have this problem what so ever. Besides thats not even true compressor surge, its turbo flutter.

[18vwT]

how many lbs of boost are you runin, cuss im thinkin your not runin enough for the hks to work the way it should. all other vids with an hks work perfectly every time.

[Funboymark]

I have to say, THE BEST BOV IVE EVER USED IS MY HKS SSQV.

[papaown]

This video makes me laugh. It's not HKS' fault that you don't have the BOV tuned correctly, or have the right insert, that makes you look stupid. This bov should work perfectly, the HKS supra runs 6's, and still has an HKS SSQV bov. 10 bucks says PrestigeRacing started selling the HKS bovs, and now only carry Synapse bovs, so they decided to make this video lol.

[22Moyboy]

haha this video is lame.. and so is the scion in it. get a real car

[brizzlefizzle]

Really? A scion? -_-

[ichbingott4510]

I wonder how much Synapse paid you guys to do this?

As well as how long it took for them to show you how to stage a fake "comparison"

YOU, PrestigeRacing, are complete sell-outs. I hope these Synapse valves are on your moms' cars when the engine surges and blows.

[EsoTeriC]

ROFL SCION TC

everyone knows the tc motor is a piece of shit, why do you think ken gushi has to resort to an engine swap while racing FD.

and yea my car will rape ANY SCION TC (minus chris rados)

so please re-frame from talking shit unless you can't back it up.

FWD LOL

[01damion]

hks is loader and sounds better



[LestatThirteen]

Never heard an HKS SSQ behaving like that. Sure you installed it right and the valve is good? In my experience, my cars have always driven better, felt stronger, and been more streetable when I put HKS valves on them. Think yours is messed up or the install was botched

[quitbeingthatguy]

great car man.....wait is that an automatic....nevermind

[ottzillator]

turbo->sport

automatic->grandma

the whole concept of a automatic in a "sportscar"is wrong.

i dont even thnk there was something wrong with the hks valve itself.

[XxJxX1337]

What a bullshit test. Get the damn car into full boost and the HKS won't flutter. What a ridiculous way to promote a shitty product to an unknowing public. I'd LOVE, absolutely LOVE to see a product comparison done in a laboratory by an unbiased mediator. HKS is the superior product, hands down.

[90camryV6]

putting a bov on an automatic???? sounds odd to me; not the bov but, the idea of it on an automatic

[myfinalhour]

driving your auto to make it sound like a manual FTL

[penaguay]

love the car! one of the best tc ive seen!

but theres nothing like having a clutch there!

automatics just dont entertain me!

badass ride! tho! love it!

[sparkyricky09]

nice clean car ur shop does good work man

[jjrock5]

This is bs. It's almost as fake as when they said that Tial didn't have a quick reaction time. In reality both HKS and Tial are great bov's and many high performance cars run them.

[DreEzed]

alot of ppl say HKS ssqv leaks...

[soccerballtux]

celicaboy thanks for that comment, good point, makes perfect sense.

[hinnyrsx]

hks=ricer.

[arsenic06]

yeah and you must know what a ricer is. douche bag

[666starlet]

if u actually lifted ur foot instantly off the throttle instead of slowly lifting off the throttle the hks valve would work properly...

i know because i run one myself, and instant lift off it vents perfect, left off slowly and it stalls the turbo....

[aconfusedazn]

regardless of how you let your foot off a good bov should not create surge like that.

[justforkiks29]

1) I doubt most of you own cars, and wouldn't know the first thing about manual trans vs auto trans. The only difference is preference. Both can be tuned to race in any fashion and be tailored to the drivers preferences.

2) To the poster of this video your having stall problems after bov discharge due to not being recirculated, and the longer discharge means there is still pressure in the intake system. Better to let it out and keep air flowing towards throttle body for faster turbo spool.

[Balloonpenishat]

automatics gay

[crashinc06]

for one lay off most professional drag racers use auto . one thing i wanted to no is what is your psi? and how big is you engine ? hks are known for the flutter there mainly ment for being around 20 psi or more for some reason there real stiff i have seen them on stock srt 4's and the run 14 psi and they run really well on them . most of the time when you have flutter is because the bov is set to high or not enough boost or both

[FDNY101202]

1) chick car... 2) automatic chick car... 3) turboed automatic chick car...4) 200+lbs in unnecessary weight... but i guess thats what show cars are...

[AceCampano]

dont forget fwd :)

[b20002003]

??????

[bustacap12]

Cool ride bro ...

[R6BigO540]

I literally stopped watching this video after i saw that it was an automatic. Nothing says "I'm a faggot, and don't know how to drive" more than having a ricer auto.....wow

[stillshady1]

nothing says "im a bitch ass hater that rides the bus everyday, cuz my mom wont give me a ride in her 86' dodge mini van" more than a pussy that talks shit on the internet....WOW!

[R6BigO540]

...more than a pussy who talks shit on the internet...haha i believe you just did dumbass...roll up on my r6 and i'll show you a bus rider, faggot. i'll leave you sittin waitin for the bus.

[stillshady1]

R6? yea right more like Rnothing your a idiot man get a life and stop hating on what other people have just cuz you cant afford it doesnt mean you gotta talk shit on the internet about it fucking loser

[R6BigO540]

WOW. you are SO good at comebacks. haha i know i couldn't afford and even if i could i wouldn't waste my money on a piece of shit auto. you couldn't pay me to take and auto....ESPECIALLY an auto ricer. All i'm sayin is that this dude could have spent his money on a lot better car than that.

[stillshady1]

all im sayin all im sayin no one gives a mad fuck what your sayin bitch get a life and stop hatin if you dont like it dont watch it idiot

[R6BigO540]

haha that i can and will do my friend. and you can stop hatin on people who talk shit cause your ass had done nothing but talk shit....just so ya know.

[maverick27502]

sounds like a lot of compressor surge to me. good way to blow a turbo. but kudos for boosting an auto. It's not done much

[kabism]

thats just..........sad

[tmitchell6]

wow... your car is slow... and gay... and automatic. what an achievement

[Snox440racer]

@tmitchell6 man i agree why an automatic? what has this world come to..

[montegod7ss]

Don't listen to the ricers talking about a manual conversion. It is easy to spot manual turbo cars at the drag races, they are the ones on the trailer with a DNQ.

[SOFLA09]

Manual conversion!!!

[MistahMofro]

automatic turbo? Learn how to drive stick and if you do please swap it over.

[koldfire08]

Haha that fan is TINY! lmao

[H1shman]

i think the synapse sound the best no gay whistle noise

[nznew200sx]

lol auto turbo cracks me up

[poeticromance]

you should do a manual conversion...

[soquick1ad]

wtf get a bigger fan for the dyno hahaha

[mechlad]

you are a shit driver!

your cars auto! why would you continually take your foot off the throttle like that.. its not a manual mate!

wanker

[coppertyler]

when ever he lets go off the throttle thats when the BOV does its job

Wanker...

[shawnae86]

umm your an idoit first off. second the car is manuel..mate.. and when he takes his foot of the throttle its called shifting dumb shit.understand...?

[vr6muppet]

It says automatic transmission (54 seconds), understand...?

[SOFLA09]

Dude you can make a car sound like its a stick when its really automatic.

[keokechung]

the first test sounds like you have turkey power instead of horse power. lol

[ACupOfTeaz]

LOL

[celicaboy666]

the reason the hks valve was making it flutter was the slow close of throttle.... and the synchronic one was getting a snapped shut throttle..... easy to see it and hear it... people arent all that dumb u know...

[vr6muppet]

For normal driving in an automatic, you shouldn't really even need a bov. There really isn't much reason you should be going from boost to an instantly closed throttle, at least not often enough that I would fear for the life of the turbo. It certainly isn't bad for the turbo, your MAF based ecu might not appreciate it, but I do wonder how you are driving this car that made you think the HKS wouldn't do the job, oh well. Glad you found a valve to fit your awkward driving style.

[SubaSmash]

is this a ima suck ur dick if u sponser me video for synapse?? i have the ssqv on my daily driver and have no surge at all whats so ever.

[infidels24]

Good stuff! Thanks!

[hubi000]

Ohhhh Wiiiiii ! Sweeettttt sounddddd ... long and sweeeet !

How Many psi your turbo ?

[BrtshAmerican6]

can sum1 fill me in on wtf a BOV is? im slow. lol

[ShaolinSoldier90]

That is why google was created :P

Blow-Off-Valve (BOV) get it?

[BrtshAmerican6]

well obviously. lol. I mean wut does it do/how do un install it.

[hagileseve]

a blow off valve or wastegate is used with a vehicle that has a turbo, you dont need a BOV but basically what they do is release backpressure being created from the turbo to stop compressor surge from happening which is bad bad bad

[BrtshAmerican6]

thank you so much XD. lol. you just saved me from putting a bov ina stock engine. and yea, im that dumb

[vr6muppet]

A BOV and wastegate are two very different things.

[scottiethebody0]

times 2

[vidal2jz]

gay automatic!!!!

[gnova68]

i agree gay automatic

[rooty2t]

while i will agree with this...

take into mind he doesn't loose boost during the shifts ;)

[PrestigeRacing]

We'd be more than happy to put one of our automatic tC's up against one of your cars... Hit us up, we're in SoCal. We'll even provide a camera to document everything ;)

[DropThatHammer]

@PrestigeRacing Theres no fun in driving an automatic, your not a car enthusiast at all. I live in Whittier, hit me up for a race I have a few spots. WHats your 1/8 or 1/4 time?

[NaeJoy]

@PrestigeRacing That doesn't change the fact that automatic transmission is gay.

[illestk24civic]

@PrestigeRacing do you race in automatic cars? is that a joke?

[Pamfilo22]

@PrestigeRacing Hello! Are these legal in California I know you said you are in SoCal, but are they legal I just moved here and it sucks that there are so many things that are just illegal. Nice state, but these laws are pissing me off... :/

[ceelm]

@Pamfilo22 nothing legal in socal any mod that is not oem is illegal in socal

[1974dusterkev]

pretend stick at 6:00 test drive

[94jettameowpsst]

the way you let off the throttle has a lot to do with it surging. I have a 35r on my dsm and at full throttle at 2k rmp itll start surging too.  I can get my Tial to sound EXACTLY like that if i let off slow. Interesting none the less, id run one just to see the difference.

[LiLTMac123]

wtf car sounds like crap

[metalicsupra]

hks is better. you don't see 700rwhp supras with a synapse POS installed do you? no they usualy have hks or tial.

[PrestigeRacing]

So because everyone's using a more established brand, anything else is automatically inferior?

To each his own, but ALL of our tests, and each person who's switched to a Synapse over HKS, they've had no desire to go back.

[gotboost15psi]

automatic....hahahhhahahahaha.­lmfao.................jezzz is this like new age rice

[PrestigeRacing]

Lots of drag cars are actually automatic. No downtime in shifting ;)

And aren't many supercars switching to automatics? Hmmm

[jvlazzar]

your ghey scion is neither

[unrest101]

Lots of drag cars are automatic for more consistent lap times. And these supercars you speak of aren't switching to automatic gear boxes, they're using tritronic which is very different from a conventional automatic. Mainly because many of them are influenced by formula one cars.

[PrestigeRacing]

Most peformance/super cars have automatic tranny's that allow manual control of the gears They still have torque converters though. So I'd still consider them automatic. A bit different from the one in a Scion obviously, but still within the same category. Double Clutch tranny's fall under that category as well IMO, like the one in the SL5 AMG .

[Jaran912]

@PrestigeRacing anything without a third pedal is auto to me

[DarkGodV]

lol auto

[ccbikeryder]

lol @ lol auto. hahhahah.

[graveplott47]

lol @ lol @ lol auto hahhah

[pavendort]

EVERY video I see of the Synapse guys bashing HKS are sponsored or something. ALLWAYS show the HKS surging, and never the Synapse. I have the HKS, NO adjust screw (fell out) and it never surges. Seen the Synapse surge before tho. People need to know its PREFERENCE! Neither is better or worse. Tho I would not get a Synapse because they go out of their way to make the HKS seem like crap. There is a reason nearly every street high hp turbo car uses them.

[squarecnix]

hahaha scion AND automatic lmao turboed? what a joke

[PrestigeRacing]

Lol, your ignorance is showing bolt on turbo kits make tC's that will hand it to lots of "sports cars".

One of our tC's had a Turbinetics kit and was able to consistently take Evo's from a line. Wait till you see a video of the tC we've been working on ;)

[squarecnix]

lawl id love to see it. pls msg me when its up champ

[Antartic440]

bullllllshittt Tc's are not good.........post a video of a tc taking on a EVO, prove it.....even civics are better then those fucking camry engines or should I say Tc's.....hahahahah that is just a family car engine...come on................

hooooooo automatic lol hahaha

[PrestigeRacing]

lol, search for yourself. There's a video of Chris Rado's tC raping AWD cars at Super Lap Battle.

And his engine is even less built then ours lol.

[4G64TurboSpyder]

...are you kidding me? I did wholesale business to Chris when we ran World Motorsports in Reading Pa...trust me, he dont run a Synapse AND his car is much farther built than this thing if this is the one your talking about.

[PrestigeRacing]

This is in response to another comment. We never said that Chris was running a Synapse setup, but that his engine was less built than one of our test cars. It's a Black 5 speed 2006 tC.

Chris has stated repeatedly that his motor only has internals. In fact, a large amount of his car is relatively stock, including the tranny. Our tC's motor has a upgraded pistons, rods, cams, sleeves, etc. It's definitely more built than Chris' "Black Betty".

[4G64TurboSpyder]

Up until a year ago, indeed, Chris' Black Betty was for the most part mainly internals...but that also wasn't the main motor he and Eric were planning on using when Jose and I were a main source for his "experimental" ideas lol. However, I lost contact with him when business decisions of moving to CA were contemplated...and again, I can't really talk though cause I don't know exactly what went into your TC's build either...so yeah my bad man lol.

[pundit116]

+1 bud

[WTFDanger]

I have a Synapse and it doesn't flutter even at low rpms and high load. You should probably go out and find someone with this BOV/BPV and take a listen for yourself (maybe even drive). The Synapse has a nice crisp, clean sound to it, holds boost very well and throttle response is awesome.

What all of these test are lacking is a very controlled environment, driving on the street sucks, this way all doubts are removed. I want to see the HKS/Greddy/TiAL/APS and whoever PROPERLY set up, then ran.

[PrestigeRacing]

Can't get much more controlled than on a dyno ;)

[WTFDanger]

And show the dyno readout of boost pressure. If you really wanna show off the Synapse, it's what you're gonna have to do (along with proper setup of the competitions BOV/BPV).

[12410963]

my hks bov is exactly the same as yours shown and does not make compressor surge noises or fluttering under any load conditions.

not sure why yours does??? rigged???

[PrestigeRacing]

Why would we rig this? We're not sponsored or endorsed by Synapse, and we sell HKS BOV's all the time lol.

[metalicsupra]

im pretty sure because the most respected garages in the world recommend HKS

[funitsu]

part2

Your tests did NOT put both the BOVs through the same conditions. I can LOAD UP ANY BOV at low RPMS and more than likely there will be SURGE if I lift off the throttle just enough to close the throttle body and build pressure between it and the compressor.

[funitsu]

Here's the difference. When YOU had the HKS in there, YOU drove at lower RPMs with MORE load. More boost was made and not enough vacuum for the HKS to fully OPEN. The DRIVING you did with the Synapse was with WOT driving and HIGHER revs. When you LET OFF you get MORE vacuum at higher revs thus less surge. When testing the HKS on LOAD, you lifted slightly so the throttle will close thus the HKS not being able to open, therefore compressor surge. You DIDN'T do that with the Synapse.

[stolenfiend123]

Actually to tell you the truth the TC is Just not producing enough suction for the HKS SSQV to work fully to its potential. I Have one on my WRX STI and its loud as hell and it sounds great. granted i get backfire cause it makes the car run rich but i can deal with it.

[turbotj99]

That's why you recirculate it until you eliminate the MAF or go with a GM style MAF!

but i guess if you just want to sound like that and be slow, thats cool...

[pinespeakz]

You have no clue what your talking about do you?!?!? First off the reason why his HKS isnt very loud is either the turbo isnt moving as much air as your car either because of less boost or a smaller turbo. Secondly backfire is fuel combusting in your intake manifold. Afterfire is when unburnt fuel combusts in the exhaust side.

[tbond86]

the hks sounds like you dont even have a BOV. the synapse sounds good. would like to see a comparison to the tial if you ever get a chance.

[eastbxc]

wtf automatic...i am just surprised that tranny can take it

[Soulquarian]

There are quite a few boosted automatic tC's. The threshold seems to be about 250whp though.

That having been said, just wait until you see what we've down with our signature series kit on a manual...;)

[510les]

Automatic AAAAAHHHHAAAHH!!!

[mapy8686]

if I was you id drive that car off a cliff with a dildo in tha mouth

[PineappleDevil]

lol...i love when people in automatics let off the gas to make it sound like a manual

[pancit7]

hes only doing that so u can hear the sound..

[aceflipgt23]

wow auto....

[DSMERGSX]

that SSQV does not sound like its venting right.. i have both gen's and neither do that

[Soulquarian]

It sounds that way on almost every tC we've heard with the SSQV.

[DSMERGSX]

thats weird

[dhexter143]

ei!!!!! wat kind of bodykit is that!!!

[dalamaarthedark]

The HKS is able to hold very high boost pressure. What is the Synapse rated at/what were you testing it at? I'm looking for something that will hold around 30psi w/ no leaks.

[synaptic1]

Synchronic is pressure tested not to leak at 100 psi

[blueturbotc]

The "flutter dump you are trying to get rid of is still there. The reson whay it is less noticeable on this BOV is 1 it has that redicouls ANTI stall thing added on. Remove the Insert on the HKS and guess what IT DOES THE SAME THING as this Miracle BOV.

[thedowner]

word

[deathbyc4]

i got mine on and sounds great, waiting on tuner to get time to run on the dyno. vids will come shortly after.

[synaptic1]

For the guys that recirc their BOV, one of the great sidenotes that we've been hearing is that people are getting more vacuum from the engine. This is awesome for helping out their braking by increasing the vac to the brake booster.

[Soulquarian]

Love this BOV on my ZPI tC! No more throttle delay FTW!

[chintastic7]

nice...i thought the hks was adustable....i have a hks nd i havent run into any problem with surge...wll i am running a pea shooter turbo tho lol 16g...nice vid tho...and nice car browndogg...its comin along nicely

[synaptic1]

Prestige- That video was awesome! Thanks for taking the time to put it together. I'm posting it on our Youtube channel

[BrownDogg]

Excellent video of the comparison of the BOVs. That is my car in this video and the Synapse BOV definitely solved my problem.
