turbo two stroke

[ismokewead420]

your typical lawnmower engine is around 150 cc...lol

[motonick34]

dont call people out if you dont know what your talking about! a 2stroke makes power every revolution (every 2strokes), a fourstroke makes power every 2 revolutions (every 4 strokes). also, most car engines are made for transport not performance (to an extent). where this two stroke has hemispherical heads, a vw jetta doesnt (to my knowledge). two strokes are crazy. still a scooter that has that much turbo lag.... haha

[bmxty82]

Let's blow that fucker up!

[EpicScandinavian]

@ejhieviugiejbv how did that little engine's internals hold up to all that power?

[amadzack666]

is it 50cc or 150cc?

[hissy08]

@amadzack666 50cc

[rustyATV]

42 Horsepower at the rear wheel!? HAHAHAHAHA! That's nuts!

[SPDKNGG]

Took awhile...lol

Cool none the less. Cheers!

[winnabego]

wow that winds up to infinity!

[sentineloffreedom]

haha I live for sleepers and this, my friend, is completely badass :D

[gigobait]

Talk about fucking turbo lag

[roanconnorjohnstone]

vespas nearly are 125cc and bigger not 50cc

[turboboyyea]

thats awesome i want to turbo my 4-stroke 200cc dirt bike but some great info for that is put a smaller turbo on it they make them half that size boosting would be way faster (ALMOST INSTANT) i would love to see that.

[epicstove]

42 hp from 50cc?? Amazing

[gigobait]

@epicstove He's full of shit, if that was a 50 cc and had 42 hp that's mean i could turbo my 2.0 jetta and get around 1900 HP, impossible. That little 50'cc would rip it self into pieces at 42 hp

[nickernosher]

@gigobait why you think hes full of shit lol.. 2 trokes produce huge horsepower in standerd trim for there dispacment anyway.. your missing the point of a 2 stoke totally.. it revs high.. producing power all the way to the top, with a distincly strong narrow powerband unlike a 4 stroke wich is more linear.. all said i bet if you can get the right boost at the right time ie.. when in the power band i bet you can gain a substantial amount of horsepower.. dont be a hater man..

[gigobait]

@nickernosher Because i worked on 2 cycle engines for a few years now. And if a 50 CC aluminum block head is producing 42 HP it would rip it self in little tiny pieces...

[thdmtr]

@gigobait the jetta is a 4 troke, you cant compare to two strokes, you stupid. the power to weight ratio on two strokes SMOKES the power to weight ratio on 4 strokes. im sorry you're wrong.

[spindlerkart]

CREDO ! EU ACHEI QUE FOSSE TROTI ESSE VIDEO ! , PUTS ! A VESPINHA GRITA BONITO AINDA POR CIMA ! , FIQUEI IMPRECIONADO !

[jojothedog1234]

I love how all the negative comment people have NO fucking idea what they are talking about yet they are on here pretending like they do. What's the point of spreading bullshit that is incorrect? Why do you assholes do that? What do you gain? Does it make you feel less stupid when you pop into an internet forum and pass off some of your shit as truth? Your ignorant opinions are not fact you fucking idiots. Look at ZeroKenshin..fucking moron. Go fuck yourself you internet retard troll.

[buzneg]

8hp on 50ccs? 50ccs is usually only 2 hp, what engine is this?

8hp to 42???

[KapteinOpel]

@buzneg Most 2 hp 50cc's are downtuned for moped legislation, the full effect versions are usually around 5 hp... But an old Vespa like that is hardly more than 2,5 hp stock, so it must have a tune-up cylinder with more than 50cc to achieve 8 hp.. but 42 hp.. A 125cc competition crosser has something like that.. If the figures are divided by 10, i might believe it.. It was a 0,8 hp stock version that was boosted to 4,2 hp with a 2,5 hp cylinder and a file... ;)

[driftking9293]

how did you get to much power whit a turbo in a 2 strocke bike

[BLOODYKnuckles2000]

got any advice for putting a small turbo on a 7.5 outboard motor? i am going to do it eventually for sure but just wondering if you could give me some pointers, thanks!

[BLOODYKnuckles2000]

just popped a bonner from this :)

But can somebody explain to me how a turbo on a two stroke works? i thought that they only worked on 4strokes and that there was no gain in power when used on 2s????? or is it that the turbo has to be located after the expansion chamber in order to got a noticable power increase? plz help me out here guys, thanks!

[CHickenWing00794]

Hey good Job ;-D

Where can u buy sooo Small turbocharger??

[christosGTAIV]

now this thing is a jet

[sweffe96]

Haha, 42 hp! Shit!

[1469N]

they have been putting turbos on 2 stroke snowmobiles for years. you problem with spooling is its just to big of a turbo.

[Hellmth]

Guys, this is awsome! I never thought a turbo would work on a 2-stroke! Where did You get a charger in that small size? Please do some more videos, i`d like to see more of that engine because i`d like to build one, too. Thats exactly the style a scooter should have: a powerful, mean machine but a clean, average look. I`m from Germany, where are You from? Guys, i think about a visit, i`ve got to get a live experience. Keep on tuning!

[mickeynismocat]

Thats got nearly as much power at the back wheel as my KTM620!?

[1991mark1991mark]

what turbo? i need to know as i want to turbo my kart engine write back asap

[RandC48]

...google it.

is the engine 2 stroke or 4 stroke?

[greyfields]

cant you tell by the sound? omg 42 hp XDD thats near my 250 power lol

[elchicoboy]

wow it has more power than a honda... 0_0

[joeyteamxracing]

thats true two strokes run like shit with turbos unless in cold climates because they need cool air to combust right

[ejhieviugiejbv]

and i know people r just dieing to jump on the fact its 50ccs but 2stroke so as far as a turbo gose its like a 100cc if it were a 4 stroke the it would not spool ever but its a 2 stroke so it can spool it. it just takes a long time

[bleachworthy]

@ejhieviugiejbv It really all depends on the turbo, the motor, the load, even humidity. Your best bet though is to have a smaller turbo that gets to capacity faster, as there is no way that this motor could totally max out the turbo in the video. smaller turbo and you can start to spool as low as 2500 rpms with a good load.

[xandelee]

whats the original power? anyone knows? im curious

[ejhieviugiejbv]

like 8hp

[xandelee]

@ejhieviugiejbv OMG MAN FROM 8 HP TO 42 HP WITH ONLY 0,6BAR? IS THAT CORRECT?

[golfraggarn]

@xandelee if it is 50cc its like 2 hp.

[bonebreaker27]

its not the only turbo 2 stroke engine that its build so its possible that the 2 strokes work with turbo

[80amnesia]

you can't apply a turbo to a 2 stroke engine

[ZeroKenshin]

that is true, two stroke runs best with open carbs than turbo =)

[ejhieviugiejbv]

there r jet skis with turbo 2 strokes with boost just dont comment with out looking at facts whats out there and trying it

[50centmnm]

@ejhieviugiejbv Howd you get it to work after the expansion chamber, after all doesn't the expansion chamber throw exhaust gas back in and wouldn't the turbo just eliminate this whole process, therefore eliminating the need for an expansion chamber??

[slimgrey]

@ejhieviugiejbv Those engines have exhaust valves like 2stroke diesels which is why they actually benefit from forced induction. The Piaggio engines used in Vespas don't have exhaust valves.

[Blaze0303]

@80amnesia: Don't be so closed minded!

Diesel 2strokes won't work without them, and having a turbo actually takes away the need for an expansion chamber.

[nightsunfire]

pressure built up in the intake is matched in the tuned pipe SO .. no the boost will not blow right threw the ports and out the pipe CAUSE it takes pressure to make pressure dumbasses and for the reeds matched ... easy again what ever pressured air passes the reeds goes into the crank case the piston comes down (BDC) and creates a greater pressure then what was pushed into it as it would normally do... regardless of the pressure

[ejhieviugiejbv]

ok theres a dyno for u people to see

theoreticly a boost botle works but in practice it dosent

small exuset ports and big intake ports help keep boost in there now when u get off the throtl in boost it sucks and it runs lean becuase the expantion chamber is under low preasure but when u get on it its a high preasure and that helps it to i have resently turboed my 1/10th scale nitro car it was a lot of work and some 1off parts but it runs well and its at 3psi

[MoreBassproductions]

@ejhieviugiejbv what kinda turbo is that?

[palledrengens]

a to stroke engine with any kind of boost will when the piston is all the way back, press air in to the channels while fuel are trying to get out!?!? it can not be done in the same time cause boostpressure is continuesly and dosen´t stop just because fuel want´s to come out.....it doesen´t work that way so please teel me and others how you perform this metod............!

[fpvshitsonhsv]

There just peanuts,it isnt posibal as the fuel/air mixer is compressed through the cyl walls via the crankcase

[palledrengens]

tell me how you are able to boost a 2stroke engine with a turbo since boost pressure is supposed to boost air and fuel together in trough the inlet manifold using the valves to prevent the boost going the wrong way when pistons are at bottom......?

[1skiinIan]

achieves full boost in only 3.4 days! lol pretty cool though

[thisisobvious]

also, where did you get the oil for the turbo from, since it's a 2 stroke? just ran it dry?

[emtrixdk]

lol running two stroke dry

[ejhieviugiejbv]

oil injection tank it runs premix

[thisisobvious]

the power band on that thing is probably much more thin than a human hair.

[Kemosabi327]

were did you get a turbo this small i want to do the same to my moped

[vikkiandbradley07]

looks like a t2 engine to me,

and the oil can be pumped sepratly its not hard,

a elctric pump,oilcooler,and pipes

[ejhieviugiejbv]

thank you

[at8tc]

yeah or maybe its a sealed bearing turbo like they use on the 2 STROKe sled motors!

[cerberusgoddog]

how many cc's!?!?!?!?

[ejhieviugiejbv]

50cc

[nikogpv]

vespa 50 or 125 cc?

[ejhieviugiejbv]

50cc

[prawler646]

I dont like scooters and stuff like that, but this one was nice^^ Maybe you can get it up to 0,8bar! >:D

[rdcorporation]

first i was like : -.- then i was like : O.O

[DjRewolution]

Uzasny,, taky se do toho pustim,, mooc me to zajima!!!

[MassacreSound]

that thing must run like shit. you must have brackets bolted on an pushing on your oild seals so they dont blow the hell out

[sm0kinace]

sounds like it's gonna run away in the high rpm's...just keeps accelerating!

[weetnietgeen]

I might try that on my Aerox rofl! unlimited speeds oO

[Nza420]

the only thing that comes to mind is "speed wobbles".... lol

[glenben92]

Max respect to you guys, that is wicked. i'd love to see some cocky twat try to race you on a similar bike as standard.

[meancharger]

very nice , nut how the hell have you got the turbo to work on a 2-stroke??? pls tell me, would be nice to know how :)

[Ryan2588]

You can turbo any engine that exits exhaust.

I would think a turbo on a 2 stroke would be more effient since there's exhaust comming out everytime the piston moves up.

What size turbo did you use?

[jahosaphet05]

thats very true, heres the problem with a turbo 2 stroke... the intake and exaust ports are open at the same time, so you lose alot of boost

[galactophore]

in a sense a 2 stroke is already a forced induction engine. As the piston moves down it positively pressurizes the crankcase to force the air/fuel/oil mix into the jug. Additionally the expansion chamber bounces the mix that passes into the exhaust back into the jug positively charging the jug. If you run the turbo after the expansion chamber you're essentially replacing the stinger and making variable backpressure as backpressure is reduced as the turbo spools. Done right this all works.

[ejhieviugiejbv]

yes

[50centmnm]

@galactophore soo essentially just hook it up after the expansion chamber somehow, be it a hack weld or whatever, as long as its on there?, But what if i have 2 cylinders and 2 expansion chambers?, Thanks for the help, Chris

[galactophore]

@50centmnm run two expansion chambers, one for each pipe, converging into where the stingers would go and run that into the turbo. 50cc turbo'd is hard but 70-80cc turbo'd is more usable as it can spin the turbine faster. I may go the supercharger approach.

[ejhieviugiejbv]

u dont lose eny boost in u keep it low but if u bring it high u do and messing arond with ur ports is good to

[kalagukalagu]

How you made it! Tell me!  :)

[BikesXtreme]

It proves that you can use turbo on a 2-stroke.

[BikesXtreme]

How many cc?

[ejhieviugiejbv]

50cc

[milomilitary]

I want one... I want one... I want one...

It's just great.

[nomoneysonny]

really clean installation

[RaffaLello7]

Good! i've never seen turbo on two stroke engine!

[MKUltraProject]

"whaaaa .. whoaaaaaaaaa" tard haha

[SeiNDeuHR]

haha sweet :D
