big horsepower 2jzgte, t04z at 20psi in a toyota supra

[BoardUnderMyFeet]

Compressor surge only happens when building boost....

[pipelinewill]

@BoardUnderMyFeet that is not true in any way, shape off form, the uploader knows what the fuck he is talking about

[BoardUnderMyFeet]

@pipelinewill Does this sound and look anything like this? -> watch?v=nCj6Spwl1CU

[Matthew20595]

omg i want that 4 my ring tone

[JDM20L]

nice supra mate. Im thinking about going t04z on the FD soon!

[AdamJames989]

Dose.

[lastminuteresistance]

its not compressor surge. its just a turbo using itself as a wastegate, as without a BoV, the air has no where to go when the throttle closes, so it simply charges back through the turbine (blades) which causes the flutter which is actually the blades cutting through the air. comporessor surge is when there is not enough torque being supplied to meet the speed of the compressor, as a result, the turbine slows. then when there is enough torque the compressor speed up rapidly. fast to slow. surge.

[pipelinewill]

@lastminuteresistance you forgot the part where compressor surge is air being pushed back thru the turbo because it has no place to go and also the part where your wrong. and yes, the flutter is compressor surge, yes it shortens turbo life, but not by much. also you don't appear to know what a waste gate is.

[supra2jzturbo1]

That compressor surge will eventually tear that turbo apart, but then again who cares if you can afford a new one, i mean c,mmon, He drives a supra =]

[stewari240]

nice series 2 mate

[FawxbodyGT]

dat turbo sound.

[xHATEMANjrx]

i still wouldn't run the almost zero lag t04z without atleast a decent bypass valve. but. prefer an external tial gate and hks ssqv III . they work like a mickyficky

[MonoLythandros]

I wonder how many people who keep saying "IT"S SURGE!" have ever actually even looked at a compressor flow map? It's has this crazy line on the left side that's dashed and usually even says 'Surge Line'. This is the sound of the god's of POWA PONI(aka Horse Power) procreating :)

[sammerron]

so not even a wastegate on this?

[saintluke87]

@sammerron wastegate is for controlling boost so yea it would as any other turbocharged engine. Search turbo 101 and have a read on the turbobygarrett page. If its plumbed back into the exhaust you'll never hear it. It has no BOV thats why it makes that sound. As he said its BS bout the damage it does. I ran 1.7bar in my daily driven car for 2 years with no BOV at all and turbo was/is fine. Real compressor surge happens under full throttle with a mismatched turbo, thats what causes damage

[markwtf82]

Guys, you can stop arguing already.. the car had NO BOV. That noise is flutter/compressor surge. As for all the e-warriors that persistently tell me that the "turbo will blow up" - I did 30,000kms on that turbo setup over 2 years, and its still going strong today, making over 500rwhp the whole time, all day, every day on pump fuel. If that doesnt disprove everyones theory then I dont know what will. People can say whatever they want behind computer desk, but this is 1st hand info, believe it!

[bomzracing123]

@markwtf82 great car

[DeviousH2B]

@markwtf82 AMEN BROTHER!! I COULD PULL MY HAIR OUT OF MY HEAD READING ALL THE RIDICULES COMMENTS ON HERE!

[peircedjdmboii]

@markwtf82 this supra sounds fucking mean. right hand drive mean are you in nz??

[sct911]

@markwtf82 hey bud, whats the fuel economy like during normal driving( i'd guess close to 15L/100km?) and whats the economy while thrashing the car around? cheers

[trex252]

@markwtf82 What is your reason for not using a BOV? Wouldn't it be better to use one, and not have your compressor wheel lose momentum every time you shift?

[hoodlumfromavk]

@markwtf82

dafuk no bov

[mathyu0179123232]

EW! yeah bad comp surge d00d

[AntonyTrickrider]

Come on, you can do beter then that! Show us a longer clipp of you drifting or driving threw windy roads.

Compressor surge is bad for you, just like smoking is - HIGH FIVE!

[DOaten]

How long till this turbo packed it in?

This could have been a sick setup had it been done right.

[dre1507]

ughhhh, when will people ever stop mistaking back pressure on the compressor wheel for compressor surge? compressor surge does not occur off throttle. it occurs at full load.

[BenMacKerras]

What model has those 3 small guages on the right of the tacho instead of the single one?

My JZA80 has the single, and I wanna mount my Defi's in dash.

[ThaGamePlaya]

600hp on stock bottom end?? i was gonna build my bottom end just to run 600hp... is it worth it?

[sivasli00]

that sound is the blow off valve. dicks..

[1JZdorifto]

@sivasli00 we may be dicks but at least we're not stupid like yourself. The video poster said a year ago up there that he runs no BOV. If we're dicks then your the balls.

[sivasli00]

@1JZdorifto Yeah but it's good that ur admitting urself as a dick

[1JZdorifto]

@sivasli00 and you didnt deny being stupid.

[sivasli00]

@1JZdorifto yes, Because i ain't stupid. could u shut up now please? i dont want to post a reply on ur stupid comment anymore. I'm wasting my time.

[1JZdorifto]

@sivasli00 Well, people who arent stupid use full words and dont say "aint" so you've proven my point. And you've proven you are stupid by your post that I first commented on. And heres an idea, if you dont want to "waste you time" and comment back then DONT! That fucking simple.

[sivasli00]

@1JZdorifto fuck you

[1JZdorifto]

@sivasli00 I dont like sexual harassment! LOL

[adamski100988]

THAT IS NOT TRUE COMPRESSOR SURGE!! AND IT DOESNT HARM YOUR TURBO!! What is wrong with the people on here!! evo 260's and many others do it stock,,,but u cannot hear it!! i know people who have had ther cars fluttering for years and never had a problem

[Nettikturbo]

@adamski100988 it for sure reduces the life of bearings either journal and especially ball bearings much much faster.

[callanbull]

@adamski100988 thats because people havent put any thought into their BOV, high boost obviously needs a larger port size on the valve. They also have adjustment, tighter for more boost etc. Proper adjustment means no compressor surge and all excess air is released through the BOV, rather than wearing out the turbo. And it does prematurely wear down your turbo, dont kid yourself.

[adamski100988]

@callanbull

its not about people that havnt put any thought into it,,,cars do it standard mate!! many do!! im a motorsport engineering student i study, work and play around cars all day, everyday. im not kidding myself, just people like you are very naive and read too much on the internet. this is not true compressor surge, the turbo doesnt stop!! it doesnt come close to stopping!! iv seen speed graphs and done the research.

[daveasi]

so how much HP u pushin 

[identity911]

Love the sound dude, recorded it and got it as a message tone. Everytime i get a message i quit everything just to listen to this beauti. :)

[daveasi]

is that a stock bov or hks

[elijahinky]

bad compressor surge, but I've seen lots of Supras with worse...not good for the engine, but if you have it built right then you should be ok...

[CYB117]

turbo surge sounds cool but you will regret it when the turbo has to be replaced

[is300ss]

just get a good blow off valve. shit get the best. go get a synapse

[c20let1000]

Hi im from the uk and do engine mods myself, the reason why you van hear the turbo chatter is because you are not running a dump valve, therefore the turbo is releasing the boost preasure itself, i take it you have an external wastegate as you'd have a biggesh turbo fitted?

[CYB117]

@c20let1000 the manifold is sending air back to the turbo thats why it does that a good bov will stop that from happening

[schnorky40]

Is this the garrett t04z? or the hks t04z?

[schnorky40]

Is this the garrett t04z? or the hks t04z?

[GTRwill4everLEAD]

that flutter is compressor surge

you may need a bigger blow off valve

correct me if im wrong , thanks

[stewari240]

looks good man how did you get around the air flow metres of the series 2, i dont have that issue as mine is a series one . what power are you making as my aim with the same mods is 350rwkw - 400rwkw

[twinturboteen18]

gose hard loving the gate on this thing

[h3h3ha3]

it's 4 sale ?

[themasterofallarts]

i love the sound of a waste gate

[cnknguyen]

@themasterofallarts its not the wastegate its the bypass valve..

[mmmmmtasty]

If you referring to the noise that sounds like squirrels being minced then its neither.

Its compressor surge and by god do i love the sound of a T04Z!

[gotchugotchu]

hks t04z?? has anti surge =)

[silentslayer911]

turbo flutter

[tofulenny]

this is fuken sickk! sounds exactly like my 13B with the To4 with twin 38 mm wastegates , as well as the 50mm BOV <3 turbosmart! ( - the 2jz hehe , mines rotary :D ) nice video fersure man! 5/5stars

[Scions4life]

@tofulenny I believe you, I went cruising with an 800 hp 3 rotor single turbo and it didn't sound anything like a rotory at all. But god damn was that thing nasty!

[tofulenny]

@Scions4life lol at least some peple have sense lolz , i agree w/u

[primazzz]

lol whats the point in saying its a private road when you can see other cars and your indicating?

[Senninha1960]

@primazzz

He meant to say "Private road with a real time simulation of traffic"

;)

[alcoholic420zhotmail]

you dont need a bov with ball bearing turbos

[madsupra88]

??? People like you need to get educated on turbo's before misinforming others.....

[albyBLZD]

LOL these people without bov's are hilarious..

[gsymdzd1]

its the turbo surge only

[suckmygl0ckz]

whats hilarious about not having a bov i have a DV and it do the job welllll

[loonaticc9]

nice dose mate

[supradave9]

why no BOV i thought compressor surge is bad for your blades, and doesnt it slow how fast you build boost?

[suprakilzz26]

does not effect the blades at all

[supradave9]

compressor surge does damage your blades, its negative pressure on blades already spinning in one direction

[89jdm7m]

i think the main concern is the shaft the blades are attached to..... that and the bearing the shaft floats on

[bllbrd]

Sersiously, can't you all just appreciate the car for what it is. I have a GT35R on my supra and it makes a similar sound. It's compressor surge. I have run the turbo for 3 years and there I have no reason to believe that a BOV will prolong the life of the turbo. Speaking from experience.

[celicaboy666]

depends on a few things to man... i run a bov and still get compressor stall under 20psi.... my bov is only set to crack open at more than 20 cause i dont wanna risk it... i know it may not happen but yer.... it doesnt get cracked much though cause i love the sound of compressor stall tooo much

[89jdm7m]

i believe the idea is to relieve the forces applied to the compressor wheel and impeller shaft (compressed air rebounding off the throttle plate when it's suddenly closed)..... not only this, but when a gear change is made..... the compressor wheel doesn't slow down nearly as much compared to a set-up w/ out a bpv....... anyhow.... i can't really believe i'm explaining something so simple

[eyrieeyrie]

its what we call in australia a dose pipe, its a piece of pipe that goes onto the end of the turbo, making the compressor surge louder.

[markwtf82]

umm.. no gay "dose pipes" on my car. its got a hks air filter into a straight bit of 5in pipe then into the turbo, then modified blitz intercooler piping to accommodate the single turbo, and a 4in thick blitz intercooler, with no blow off valve. I dont care for useless mods like "dose pipes".

[eyrieeyrie]

are you stupid? you just re wrote exactly what i just said, a straight piece of pipe that either has a piece of mesh or pod filter then then gets clamped onto the turbo. therefore making the compressor surge louder

[markwtf82]

if you go ask the VL turbo boys what 'dose pipes' are, they will go into a speil about long beaten up pipes that are specifically shaped for it. my turbo basically has a filter bolted straight to the end of it, nothing special done at all to enhance the sound. every single turbo car has a bit of pipe going from the turbo inlet to the air filter, so are you suggesting they are all "dose pipes" ?

[eyrieeyrie]

you mentioned below that you had a 5inch pipe bolted to it.

take off the 5inch pipe and pod filter and watch it not flutter as a loud, as there is nothing to amplify the compressor surge.

put that 5inch pipe back on either with pod filter on end or a piece of mesh to stop crap going into the turbo inlet, aka what people call a dose pipe.

if you have a intercooler i.e vl turbo you move your afm to the intercooler piping so you dont need to use the airbox.

[markwtf82]

my inlet pipe to the supra is very short, around 8 inches or so. its essentially only there to get teh filter attached. I have previously run with a large alluminium trumpet which has no filter, and the flutter is still just as loud, so i dont think in my case anyway, that the sound is from having the pipe on it. i think its more due to the size of the turbo, the volume of the intercooler and how much boost im running.

[eyrieeyrie]

have a look on youtube put in dose pipe and have a look at them if you dont know exactly what i mean.

but anyway mate nice car none the less.

[crazyredneckwifknife]

@markwtf82 Just to clarify dude, its not a compressor surge. I am not meaning to insult you in anyway, but they are commonly misunderstood, that 'flutter' you hear cannot be coming from the turbo having a compression surge, these are not possible under normal operating conditions. If the turbo was to have a compression surge it sounds nothing of that nature and the car would be jumping violently with the boost coming on and off quickly. What the 'Flutter' sound is coming from what I have gather

[crazyredneckwifknife]

@crazyredneckwifknife is because you are venting to atmosphere. Not having a ago at you, but Thought I might though my 2 cents in.

[kyleisreallycool]

@eyrieeyrie who cares flutter sounds bad ass

[ofnarcr]

@eyrieeyrie you're talking about an intake pipe. Sheesh..

[fstylezkrNNN]

@markwtf82 thats a cheap doser for a VL the professional way to get the sound is how he said it which is what you have Jheeeeezus

[MrShakotan]

@eyrieeyrie its not compressor surge as its often called. its simply turbo flutter. true compressor surge is very violent and does damage. with the standard turbos and standard BOV i get a little bit of futter on my 2jz. i hate it, but not as much as i hate psht.

[slidin2sidewayz]

@markwtf82 ok well there u go right there u only get flutter when either ur NOT running a bov, the pressure is to great for the bov, or it not openning at the right time causing wastegate chatter running a "dose pipe" or not doesnt change a thing. i had the same wastegate chatter on my rb till i added a dual hks bov fo boost i was running. witch mine and ur car r very similar

[jsaulgodoy]

@markwtf82 no blow off valve ohhhh.....they exist for a reason...gona wear down those compressor fins prematurely..

[mikedsm12]

@markwtf82 haha yeah buddy!

[Godeepgts11]

i want that gauge cluster! (and gauges too)

[goodoldjam]

Is the flutter for effect or does it add something? Other than the extra wear. I would think its defeating the purpose of a bov..

[blandruff]

very nice setup, especially the fuel system. Good to see people out there that arent running those shit walbro pumps.

[stuie334]

bad compresser surge man

[surlograsp]

agree. sounds fuckin' great, but poor turbo :'(

[slidin2sidewayz]

@stuie334 yea u and the other 8 people that rated u should really learn what u r talking about bcuz compresser surge happens when its under load,boost, SURGE causing the compresser to bump and have a unstable surging flow and sound lik the turbo drys out bcuz the backpresser on the wheel pushes it into the housing

go watch "True Compressor Surge" its a former r33 d1 car i used to compeat against showing REAL SURGE in action

[slidin2sidewayz]

@stuie334 yea u and the other 8 people that rated u should really learn what u r talking about bcuz this is wastegate chater not surging. compresser surge happens when its under load,boost, SURGE causing the compresser to bump and have a unstable surging flow and sound lik the turbo drys out bcuz the backpresser on the wheel pushes it into the housing

go watch "True Compressor Surge" its a former r33 d1 car i used to compeat against showing REAL SURGE in action

[sti4nz]

If they run without BOV's they might blow the turbo, the point by turbo is to let out the pressure in the turbo, to not blow it.

[injen95]

what bov is that?

[Falessi]

50mm tial bov

[silkrodd]

hahaha, Nobody tells us anything.... But I know and you should know that if the turbo fins are spinning at a sht load rpms and all of a sudden all the air its pushing is forced back into the turbo... that equals pre turbo failure.

[silkrodd]

Not tryin to be an aszhole to the video poster even though I might've seemed like it.

I just dont understand why people run turbos without bovs!

Anyone who believes Im wrong about turbo surging prematurely destroying your turbo! Lay it on me! give me your argument! tell me why turbo surging is cool and isnt bad for your turbo!

[nitrousboy0311]

Could be a DBB turbo which cane take alot of stress and stand up to compressor surge

[silkrodd]

only dumbass kids drive nice turboed cars without bov's and rev the motor like that!

Did you know? and doing sht like that to your turbo will eventually destroy it! Did you know?

[markwtf82]

ohhhh noooooo..

im such a dumbarse kid.. what ever will i do! please internet guy, pleaseeee approve of me.. i so desperately want your approval!

my car, my choice. bite me :)

[argirce]

hahaha aww thats funny, i think u got it the other way around kid

[silkrodd]

Whats so funny argirce .... How do i have it the other way around? I think your the confused one ya fool... funny how idiots try to call everyone they cant argue with a kid... oh well your only an inexperienced fool who dont know wtf ur talkin about... i'll let it go...

[I2eapz]

DOSE PIPEEE ftw haha sounds nice what dose pipe u got on it

[markwtf82]

dose pipe? it has nothing besides a big turbo, a big intercooler and no blow off valve. you dont need any special piping or "dose" modification to make that noise. Formula is simply to use a big turbo and intercooler.

[AntonyTrickrider]

Would i get that noise from my supra if i uppgraded to bigger twin turbos or is it only with singel you can get that sweet sound (love it).

[silkrodd]

you must not know anything about turbos... If your car is turbocharged and you hear that sound after letting off the gas petal....ITS BAD! you will prematurely destroy your turbo because of comp surge! and IT DOES NOT MATTER IF YOU'VE GOT ONE OR TWO TURBOS!! omg sell your supra please!!!

[AntonyTrickrider]

For your information i have HKS SSQV venting out to atmosfear on my Twins. AND... the turbo/turbos will breakdown aventualy annyway or need a propper renovation with afftermarket components that are better than original. I wouldnt mind driving as long as i could with out B.O.V and then having them renovated. Not that expensive in Swe.

I dont need to sel my Supra, the rest of the engine is good!

I wasn´t asking you annyway...

(But thanks fore caring about Supras in general)

[supras4life]

Its a single i think

[I2eapz]

sounds like the afm is in the cooler piping befor the turbo ect with a peace of piping coming off the front of the turbo (look up vl turbo dose and u will understand wat im talkin about

[markwtf82]

i have no afm. running map sensor.

only pipe i have is a 12in bend going to hks air filter on front of turbo.

[YellowZR2Man]

the sound you are hearing is the waste gate

[markwtf82]

its not the wastegate. its not the bov.. its compressor surge. The wastegate vents to atmosphere and just makes a loud exhaust noise. Wastegates dont make that flutter noise.

[skylineracea09]

love that bov nice car man..

[nitrousboy0311]

Lol compressor surge sounds like a whale getting off haha

[GoDzBaPeZ]

nice compressor surge dumbfuck

[sdrapaka]

Supra YAAAAA great car -Right hand drive imported from somewhere else boo.

[2076649]

what is the name of this bov???

[initialmoe]

The noise you are hearing is not a good sound...this type of Surge and destroy Motors and Turbos.

[tuttimannnnn]

i LOVE the noise of the compresser surge ( 3 seconds) it sounds like a little evil laugh or a giggle. loll

[bmxerboyee]

if that was compresser surge it would be jumping around

[JayMark2049]

Nah sorry about the stupid thing, didn't mean it. I thought compressor surge could damage the turbo or shorthen it's lifetime but it seems that it's not the case on every car/setup. Nice car dude, I want a Supra too.

[markwtf82]

cheers, i am aware the lack of BOV is not ideal for turbo life. It was actually a measurement of my laziness - i cbfd making up a new pipe to put the bov on when i changed intercooler kits, so i just left it off :P it wasnt really out of choice.

[JayMark2049]

Allright dude! Well I'll be looking at it! Keep on going man!

[JayMark2049]

Also I said that because that sound is really IMO like the sound of a BOV. Seriously.

[markwtf82]

if you hear flutter at all, it means the bov isnt doing its job, or is too tight. if a bov is set correctly you should not get any flutter, so im not sure what bov's u have been listening to. As for being stupid - so what its my car, i can do what i want. i really dont feel the need 2 get into an internet argument about bovs. I like how it drives, sounds, and done around 30000k on this setup on a non rebuilt motor with stock internals pushing over 500hp at the wheels, so whether im stupid or not

[phatlary]

is it a hks or garrett ?

Sounds nice and pulls like hell

whats the max power you got from the t04z

[markwtf82]

garrett.

making over 500rwhp. getting new exhaust and some other mods at the moment, shooting for 650rwhp next week.

[phatlary]

ahhhh thats gonna be nice should be able to achieve those results

thats with 98 octane bp ultimate ?

[Fubar231]

Turbo flutter = bad

[markwtf82]

bad? hey ive done over 120,000kms on a stock internals motor which has been pushing over 500rwhp for 30,000kms of that, and the engine and turbo still works perfectly fine.. so... go figure ;) so its probably not ideal, but who cares. works fine for me :)

[Fubar231]

Well, what size turbo / turbo shaft do you have? I drive a MK3 supra, and ive ruined turbo's due to Turbo Flutter. You do know what turbo flutter is and what it does right?

[markwtf82]

well i did much of the work myself. I also had a 700hp mk3 supra til early this year which even though had forged internals would not have lasted this reliably. This turbo has jack all shaft play and still spins as free for around 50 seconds after i turn the engine off. Doesnt smoke, or leak.

Turbo is a stock t04z roller bearing with 0.84? exhaust.

[Fubar231]

What size trim is the turbo though? How thick is the shaft? And don't hate on 7m's there still good motors. But just saying turbo flutter is bad and can weaken the turbo shaft and cause turbo play, unless your running like a 80+ trim turbo with a huge shaft. Then that shit wont break.

[JayMark2049]

What do you mean turbo flutter and compressor surge? I can hear the blow-off valve flutter but it's no surge.

[markwtf82]

i dont know how u can hear my bov since i dont have one?

[JayMark2049]

Ha ok so you don't have one. Sorry I didn't know some people were stupid enough to have a powerfull turbo car without any pressure releif system.

[kaeme]

Flutter is when your throttle snaps shut and the pressure in the intake is high enough to force air backwards through the spinning compressor wheel which can flex the turbo shaft around. Imagine holding an air compressor the wrong way against a PC case fan and seeing the blades flap all over the place. Since in a turbo the compressor is rigid and fixed, the only thing that can move around is the shaft on its bearings.

[mmmmmtasty]

oooo thats not good for the turbo bt it sounds awesome. question did you get the gauge rings from mvp??

[JXDeaLz]

wrong, there is no bov, its the wastegate.

[Fastspoolsupra]

It's not the wastegate.

[markwtf82]

its not the wastegate, its compressor surge

[xtelenorx]

Those are the same just diferent names

[markwtf82]

errrr, sorry you are mistaken. The "wastegate noise" and "compressor surge" are completely different phenomenon.. the wastegate is on the exhaust side, and the compressor is on the intake side of the turbo..

[Fastspoolsupra]

Correct. There are 2 different wastegates, an internal wastegate, and an external wastegate. Internal is inside the turbo, external is on the manifold, and regulates the amount of combusted air/fuel entering the hot side of the turbine.

An external wastegate can be dumped to the atmosphere, or to plumbed back into the exhaust.

[Supralover79]

I like a lot;)

[SnpStickle]

It sounds so nice! What BOV do you have?

[mdeluca83]

no BOV id say.

[markwtf82]

correct. no bov

[SnpStickle]

Then is that the wastegate?

[sdc1213]

It's flutter aka compressor surge from when the turbo goes in the opposite direction. Sounds cool, but not healthy for the turbo in the least.

[kingskyline]

Correct its turbo surge, Id say sounds better than BOV

[endlessjz]

i likeeeeeeeeeeeeeee :)

[gwilmarlio]

NICE love the flutter sounds alot like mine
