Ball bearing turbos rule

[MadJDMTurboBoost]

Thats awesome, but keep in mind theres still oil pressure in the turbo, and the bearings are still wet with oil after the pressure drops to nothing (which takes a while). So a journal bearing would probably spin for a long ass time too but not nearly as long as this. Definately crazy to see it spin for sooo long!

[MrHickfarmer]

oil still pumps through the turbo to cool and lubricate it correct..?

[marek0086]

@MrHickfarmer~... when the engine is running.

[CoolasIce2]

Don't most turbos use ball bearings?

[bgjon87]

@CoolasIce2 Most turbos that we see use journal bearings they are much cheaper but don't spin as freely

[AnTHoNyB1125]

a beatle??????

[DStylesHanska]

What`s the nozzle in front of the turbine?

[enfourcer]

@DStylesHanska

Nitrous

[hoodlumfromavk]

@enfourcer slow down there brian, you got the nos fogger system on it 

[kustomcarbuilder108]

Sick bug..

[kws30777]

now that is the wildest dak dak i've ever seen!

[savagenomore]

damn, that sounds good..

[TaLoCc]

wow camera was playing with my eyes i i didnt know when it was gonna stop!

[davidjv13]

VW!!!!!!!!!!!!!!!!!!!!!!!

[b00stinz]

0:38 Ball berring

[se7en1976]

Nice.. would like to see more.

[S14lopez1]

dam i would rock that car with a set up like that

[kinsley2108]

You have to remember, spool down time is nothing, sure a ball bearing is going to reduce friction, etc. But this kind of test doesn't prove anything. Turbos that have their bearings suspended in oil have no metal to metal contact during operation. They spool down quickly because once the engine is turned off, pressure is lost immediately and friction increases due to lack of oil pressure. Purpose of oil: Lubricate, remove heat and remove contaminants.

[darkmetallink1]

Do you have any videos of this bug on the 1/4 mile?

[12345678966666669999]

awesome engine

[dill30669]

godamn thats a beats beetle XD

[XHikotheproX]

0:31 - 1:17+ 46 seconds that thing spun, after the engine was turned off. 0.o

[enfourcer]

Yes it is a BIG electric fuel pump (methanol).

[MrGustavoviktor]

@enfourcer only pussies run nitrometh...

[EVOLUTlONX]

Is that humming noise in the beginning your fuel pump? Hella loud. What is it?

[sejfiu100]

wow nice setup

[vwpromod]

Cool. I learned a lot about "my" turbo. M-Spec Motorsports builds some amazing stuff and I couldn't be happier with my setup. It has been great laying down 9 sec passes at 140+ and have only had to check the oil for the past couple of years. The cool thing is that I have 5 more stages of boost and 2 stages of nitrous that I haven't even explored...yet.

[enfourcer]

You are hearing each cylinder firing due to the 4" wide open pipe.

It is EFI intercooled on Methanol.

There is no carb so you might want to look a bit closer.

[magna59]

I'm do not mean to offend, but this unit, although very good looking, does sound like a bag of nails. Is that just because of the state of tune ? ie happy from mid range up ? Is it direct injection ? and what is the motorcycle type carb below the mouth of the turbo ? Regards Bob

[CheeseLuv3r]

They should put that in go karts o.o

[ciara0601]

wow i now understand the need for a turbo timer almost a min and a half

[enfourcer]

@ciara0601

A Turbo timer would not do anything on this. The motor is just idling. A turbo timer just keeps the motor idling.

[Bryanx89]

@ciara0601 lmao no that will happen anyway. when the turbo is extremely hot a turbo timer will keep ur car idling for a min or 2. w.e u set it for so the oil can cool the turbo off before shutting the car off. keep helps turbo last longer

[ki11joy92]

how can I fit that onto my skateboard

[Virgo801]

So i was talkin with a mechanic about "compressor surge".. And he said yes compressor surge will damage your turbo, but he still said that you can still do compressor surge using ball bearing turbo!

[str8t6]

I bet that was one expensive fukin turbo lol

[HksTopAndRock]

Wow is that a beetle engine ur crazy man it doesnt look like it anymore :D

[ph33x]

You guys are half on the money but I can't see anyone explaining the real reason for idling the engine down. Yes it's for slow turbo RPM, and yes it's to allow the oil to remove heat, but the reason behind the latter is what's called 'oil coking' (Wiki it) - If the turbo is too hot, the oil inside will boil, lose it's properties, and will form a gum that sticks against the bearings in the turbo. If this happens enough, the supply of oil to the bearings will cease and THEN the turbo dies.

[ph33x]

^ I mean shit, who turn's off their engine with the turbo still spooling boost? It's not a common thing to see. Even NA (exotic) engine owners idle their cars for a while, shit I idle down my V8 commodore, it's just a good habit to have. The main problem with hot turbo's is oil coking as mentioned above.

[moonerdizzle]

@ph33x it wasnt making boost, nor wil lthis really hurt the turbo, its not glowing red hot, so the bearings are not going to coke, and the motor didnt run that long, and also, its a ball bearing turbo, it can spin for a while with no harm done.

[ph33x]

@moonerdizzle I wasn't referring specifically to this video. Nothing is wrong what what's happening in the video here. We were discussing the reason behind dying turbos on shutdown in general.

[PAID2BSAVAGE]

sooo sick

[shuffle953]

my dads friend car has an engine the when you turn the car off and take the key out the engine will keep running for a minute or something for the turbo to cool down for some unknown reason and u can turn his car on from the key when u are inside a house :D

[theberengersniper]

@shuffle953 Known as a turbo timer. Turbo chargers need oil flow to lubricate them and cool them. If you simply turn your engine off both of those properties are lost, and that's bad. Keeping the engine running at idle maintains oil flow through the turbo and gives it time to both slow down and cool down following a run.

[shuffle953]

@theberengersniper oh ok i get it now thanks :D

[05hillbillydeluxe]

@shuffle953 its for the egts to cool down to prevent hurtin the turbo. its a goood thing to have.

[shuffle953]

@05hillbillydeluxe oh ok just like jets and stuff any its still sick xD

[123adrianramirez]

thats a sick comp turbo. how much was it, and did you get it tuned?

[abdulios]

wow that thing spooled up within miliseconds

[cyboula]

OK now THIS is a beetle !!!

[c12letmefly]

ball bearing is the shit man

[vochitoken]

Is that a Nitrous nozzle in the inducer?. Do you have more videos of this car?

[abdulios]

whats the difference between a ball bearing turbo and a normal turbo? just that it spins easier?

[ralliartfanevoix]

@abdulios bigger, sounds cooler, and looks nuts, even in spooldown. love it.

[Ravenwing3000]

is it a vw Beetle?

[GRATZIANI2002]

where are the rules??..

[robiniroven]

wow spins so long after shutdown :D...remember to let the engine idle a bit after it has been driven to slow down the rpm on the turbo and then shut down..otherwhise the it spins much faster and gets no oil..if i remember correctly :)

[caniwitech]

@robiniroven Idling doesn't slow down the turbo, it allows oil to flow through the turbo and cool it.

[robiniroven]

@caniwitech idling does for sure slow down the turbo after reving the engine...trust me

[caniwitech]

@robiniroven The impeller will be turning slower at idle, but you act like it will get clower and slower. Yes, the turbo will be slower at idle than at higher rpm, but that goes without saying. The turbo doesn't continually slow down the longer you idle, It will reach a certain rpm and then stay there, you idle it for 5 minutes to allow the oil time to carry off heat.

[robiniroven]

@caniwitech i wish my english was perfect..there are so much stuff i wanna say but i dont know how lol...but ur right..it takes a lill while to lower the rpm cause the engine is still on and the exhausts is still turning the turbo

[silvertungdemon]

i couldnt tell what kind of motor that was at first it almost sounded like a 4 banger cummins but a turbo bug thats cool

[Turbos4Sale]

@silvertungdemon a good 95% of Volkwagons that are used for racing are turbocharged.

[caniwitech]

@silvertungdemon If you thought that was a cummins, i don't even know what to say.

[silvertungdemon]

@caniwitech almost read carefully

[griz4020]

that's not a silver bullet turbo is it?

[jillnryan]

what turbo is that?

[enfourcer]

@jillnryan

Comp Turbo

[hitcb]

lmao thats one bug i dont wanna try to pull on hahaha

[Jd3211]

awesome VW

[frosty9595]

It..... It.... It wants to hurt me!

[KooKVT]

That is a mean, meeeeeaan bug. Any info on whats behind the turbo and spinning it :)

[JaxxBat]

kewl..

[0033jorge]

Rev that mother fuker

[fuzzytopbop]

dare you to put your finger in there....haha

[starlesssoldier]

I'm thinking about installing a turbo kit on my Z3. What do u think about the Kits? Like ease of installation? It says bolt on but the pipes may require some modification. Will the motor run correctly without being tuned?

[454sskilla]

so these turbos dont use any oil?

[enfourcer]

Yes they still use oil.

[marek0086]

u should have filmed a hot engine shut down..... it would have spun for even longer!

[weedeatertijs]

ha a ball-bearing is even more sensitive for running dry than a plain bearing is...

[jorgeykami]

stick your finger in it to stop it

[nbssage]

that whole you plucked into the mouth of the turbo certainly is not doing you any good. the rate at which air must flow through that turbo is something you never want to change. that will throw your air to fuel off, will it not? well seeing in how you have a bung sticking up there, your really playing with that air, and how to turbine sucks it through. i don't think it will ever damage the turbo in my opinion i am just going off fact. air is coming through at an irregular rate, thus more stress.

[nbssage]

if you are after performance, at the price of "A pain in the ass", well header wrap is the way to go. as much as you think it doesn't make a difference, it does. especially on the softer metals. every turbo essentially has some form of lag, that is just how a turbine works. working more and more to reduce that lag and increase the maximum amount of air flow will give you the maximum amount of power. all these things matter!

[enfourcer]

The cermic coating is performing the fuction that the wrap would but even more effectively.

[enfourcer]

That is a Nitrous nozzle brother.

It is the second stage. There are 2 other nozzles down in the intakes.

[Turbos4Sale]

@nbssage that small nitrous nozzle is a moot point when you're dealing with a turbocharger thats capable of 800+ CFM intake. Take a look at how many automobiles come with restrictive air flow meters - VAF/MAF and have restrictive intake plumbing and horrible airbox designs and it's not hard to see where your point about a small nozzle is irrelevent. Benchtop racers- gotta love em.

[454sskilla]

whats ball bearing mean like wats the diffrence between a ball bearing and a regular one?

[ultramaxracing05]

are these ceramics ball bearings? seem to spin for a while, seemed more likely to be ceramic

[69frank06]

how much horsepower will that put down

[ryan05753]

71mm with ball bearings

[ryan05753]

k if a turbo is so good to let it keep on spinning rev the pisss out of it and cut ur engine. let her just spin without oil feed, and watch those ball bearings go.

I have a aftermarket 71mm turbocharger in my powerstroke and it requires me to dump preasure from a tank, reverse flow to slow it down and stop asap to prevent damage.

[69frank06]

how much would 1 of those cost

[enfourcer]

The turbo cost $1,800.00

[tpvalley]

if u wrap the headers leading to the turbo the exhaust gas will be hotter so less dense so at higher pressure, spinning turbo up faster.

R those water intercoolers on inlet manifolds?

[enfourcer]

Header wrap is a pain in the ass and does not help spool-up if the turbo is sized correctly.

The intercooler is in front of the motor. Those are plenum chambers on top of the manifolds.

[tpvalley]

consider this, a very long pipe getting colder the further along u go, the colder the air the less dense, the less pressure, the less it would spin a turbo, those headers r very long, try it.

[enfourcer]

I have.

I have been building this stuff for over 20 years. This aint my first rodeo. Wanna race?

[tpvalley]

ha, my mega fast 60bhp diesel would totally.........make a lot of noise and get left behind.

[XXdriver2000XX]

Hard to see when its really stopping lol

[gavincurtis]

Put some money into that poor bug...

Beautiful work!

[garrett6699]

you may need a tune.lmao

[turbobusayar]

That is the most beautiful thing I have ever seen!!!!!!!

[marek0086]

haha!.... its pretty nice.

[12vcummins4life]

i dont understand what a ball bearing turbo is. could someone explaine

[ejeightsohct]

regular turbos are considered journal bearing. when oil comes in the turbo it lubricates while oil goes between the center cartridge and the shaft. therefor it causes the turbo to spin on a layer of oil. ball bearing turbos have ball bearings in them, similar to skateboard wheels. they spin with less friction and they spool up quicker. you can tell a ball bearing turbo when it has that sweet whistle noise as it spools up.

[hiks1969]

great video....,

can i upgrade standard turbo shaft to ball bearing type, how?

[xpectz]

i want to know too!

[axotlprogeny]

You cannot upgrade a non ball bearing turbo to a ball bearing turbo. This would require machining the center section of the turbo that was not designed to accept the ball bearing cartridge. With some turbos, you might be able to find a comparable size ball bearing turbo, but they will be priced higher than the standard journal bearing variety.

[ryan05753]

just think how long thats spining without oil. that can cause some wear right there dont care who ya are!

[enfourcer]

You obviously have no idea what you are talking about.

[sweenster123]

do you know anything about ball bearing turbos??

[axotlprogeny]

Just in case you did not read the above post, and/or are not familiar with turbos in general, there is no damage caused by allowing a turbo to continue to spin after shutting off an engine. In fact, all turbos continue to spin after shutting off the engine. If this is unacceptable to your school of thought regarding turbine engineering, I ask you to please devise a method of stopping the turbine wheel (on your own car) immediately following engine shutdown, and post a video. :P

[yamasubaruger]

That was a brilliant comment. I was wondering the same thing " how does he think ALLLLLL the turbos in the world spool down mechanical drum brakes? ".

[enfourcer]

LOL

[rudolphna54]

Holy crap

[whyzee125]

the starter sounded like a honda lol

[elninovago]

what kind of turbo is that?

[94fordf350]

enfourcer ball bearing turbo for a VW

[GabeytheNuthead]

kewl bug

[shadynebey]

That looks like a SERIOUSLY modified flat 4 in a Bug.

[94fordf350]

how many cubic inches is that motor and what brand?

[mrclown88]

Gotta love ball bearing turbos :)

Great vid.
