SAVKEL ROTARY WANKEL ENGINE

[KPAracing]

Its not a Savkel. Its a Brapkel... Brap brap brap braaaap brap :)

[metallicman711]

@KPAracing lame.

[KPAracing]

@metallicman711 I love rotaries. By the way i couldnt care what u think of.

[Texassince1836]

@copkilling745 they can also replace exhaust valves after every run, and have different cams than most motors. All motors need some backpressure for exhaust valves, and piston engines need more due to cam timing. If you took a factory truck that made 250 horsepower and 200ftlb of torque and toook the exhaust manifolds off, itd make 300 horsepower and 100 ftlbs of torque. Backpressure helps with torque

[Texassince1836]

You need a little backpressure on these motors fr ehaust valves. Piston engines need a lot more backpressure because most cams open the ehaust valve 60-70 degrees before the bottom of the powerstroke, which kills torque without backpressure. Drag racers and monstertrucks cams open the ehaust valve later, reducing the need for backpressure.

[moonerdizzle]

@Texassince1836 Rotory motors do not have valves, they have intake and exhaust "Ports". Okay. You find me a rotory motor with a camshaft and valves and I will call you a liar.

[minibikerider1]

what is that dude smoking he don't under stand rotary motors

[TheRealFobican]

Asses on fire!

[aza2speed]

@foxbodymustangboy89 check out my site and c my kart thats 6000 grand so far

[JuanPapaNicolao]

we have brap 

[DMRH69]

Made under Government contract by an Israeli company from the 1970's if memory serves me.....

Very rare today

[halpern6]

where is the rest of the lawnmower?.....LOL...

[russotragik]

i want to put this engine on my motorcycle!

[TABAGfrancis]

Please watch:

SUPER-EFFICIENT ENGINE Newest Design

[mrgixxer100]

u should fit it to ur mum

[mitteey]

it puts a shit stain on the towle

[iceman86694]

Cool engine the mazda rx dont remember have a engine like that but turbo i think... Howsoever trey have allot of potential... A 1400 cc 2 rotory can bring up over 240 Hp @ 16000 rpm

They work pretty high... I like it!

[420swimfan]

@iceman86694 Mechanical Redline of a rotary is 15,500 anything more than that any you will tear the apex seals off the rotors

[drhillaryharris]

The finest WANKLE in the WANKLE business.I cant stop saying WANKLE.

[iceman86694]

@drhillaryharris lol

[headsmess]

i dont get how a 2:3 gear ratio with one gear fixed results in a 3:1 reduction...increase?.. on the crankshaft...rotor?. then how raising the gearing will increase torque...

time to stop partying and start studying, funmaster... :)

starters, its an "eccentric" ;)

and who said backpressure has anything to do with valves?

*bangs head on desk*

[aerobubb1]

furmaster212 you obviously have no idea what your talking about, better to do your homework before making posts that make you look stupid

Search for rotary animation on youtube have a close look and you will see what I mean

[SuperSinistAr]

@furmaster212 You obviously have no idea what you are talking about, do you really believe that a rotary at 9,000RPM is turning 81,000RPM internally?

[wolfgangiceclaw]

@furmaster212 You have it backward the rotor spins 1/3 slower than the crank. For every revolution of the crank there is one power stroke, not 3. Also RPM is still measured at the crank as a piston motor.

[jzz20highwaydancer]

@furmaster212

actually the rotor moves at 1/3 shaft speed so at 3000 shaft rpm the rotor is only doing 1000rpm

[coldfarted]

@furmaster212 The shaft rotates faster than the rotor. There are 3 faces on the rotor. For every combustion cycle the crank will turn one time. That means the crank will turn 3x for every full turn of the rotor. Rotary engines don't have much low down torque : it's a consequence of the design. That is why you need low gears ( numerically higher) to get the engine in its power band.

[darkeyce02]

@furmaster212 haha you funny.

[minibikerider1]

@furmaster212 what the rotors are built into the crank shaft the speed of the rotors is the same as the shaft

[moonerdizzle]

@minibikerider1 The rotor and "eccentric" shaft are not one piece, rotorys do not have a crank shaft.

[SOHCNightmare]

Get that fram filter off of it! lol.

bobistheoilguydotcom can tell you why...

[GinoJerry86]

where did u get this and how much?... i want one

[form109]

Nice Engine!...Wankel Engines are Great.

[preludefan]

awesome!

[DW793]

Engine passing gas.

[420witchdoctor]

Imagine this little screamer with a turbo and a racing kart. Jajaja.

[aerobubb1]

thats exactly what I have planned for the second engine! Im going to make it a bridgeport turbo and fuel inject it, I have a kart frame in the shed for when I get to it just need the turbo, ecu and gearbox,

[420witchdoctor]

Oh that's nasty! :P I like that idea. I'm subscribing to your channel, man. I gotta see it in action.

[aza2speed]

@420witchdoctor  check out my rota kart with a savkel 440 in it

[aza2speed]

@aza2speed you rota kart?

[420witchdoctor]

@aerobubb1 That's bad-to-the-bone, buddy. You've gotta make a video series of the build. I'll subscribe. I want to follow these engines and get into working on them. I already know rotary engines very well and had an FB '85 5-speed with a peripheral-ported 12A, and 45mm Webber pipe carbs. What a nasty little car, but it hated apex seals :P

[tpvalley]

@aerobubb1

just port it and fit a BIG carb and megaphone exhaust and calculate the length etc.

adapt a snow mobile belt drive maybe?

[hothothotmale]

Give you a dollar for it.

[jamdread]

where did you find the engine? because im looking to buy one

[aerobubb1]

I found it on NZ auction site trademe, I have only seen a couple for sale they are rare and usually expensive, I still have one in my shed but its currently not for sale,  you sometimes see them on ebay but they usually priced around the $2000 usd mark

[aussie507]

@aerobubb1 im a kiwi and that is why i love trademe you find the best stuff

[DonHoraldo]

yeah the fire coming out the exhaust seems safe.

[acdcgranada]

Do u need 2stroke oil for it?

[JUNIORROTAX55]

is this the aixro kart engine?

[aerobubb1]

No its an savkel, its a bit more cumbersome than the aixro

[DJRackerstrance]

thats nutz

[darkeyce02]

wher can i find this? i havent found any rotorys at all

[aerobubb1]

Sorry man it sold about 3 years ago, these engines don't come up for sale very often, I still have one stashed for a gokart project, I have a frame and everything but just no time!!

[darkeyce02]

ive looked a lot too, i have a Razor motorcycle i want to use it for...

[AKAxAUTO]

I'll buy it. I love Rotarys

[pdgeman]

thats awsome.. a rotary go kart motor. but the flam comes out at your ass

[madjimms]

400cc but its sooo small?!?!

Gotta love the rotary for its power/weight ratio!

[adam27666]

hey man where abouts do you buy these engines from?

had a bit of a look on ebay and searched the net but couldnt find anything..

how much do they sell for aswell?

cheers

[aerobubb1]

You can't buy them new anymore they stopped selling them in the 80s, I sold this one for $1200nz but I have seen them sell in the US for over $2000USD so they are worth whatever someone is willing to pay for it, You are lucky to see 1 for sale a year, I have one stashed away for a go Kart project, I might yet fuel inject it and turbo charge it, I just haven't quite made my mind up yet which way to go with it but more power is good! 150hp should do it!!

[Ibringthetruth1]

excellent video.

[aerobubb1]

I usually use a motorbike gearbox and take out the crankshaft and make up a straight shaft to go in its place and blank the barrel holes, and then use timing belts or chains to connect it too the engine,

As for engine life they are usually good for 1500hrs if treated correctly

[aerobubb1]

Yep they are great for karts, I sold this engine for 1200 NZ dollars, thats about 700-800 USD, I have seen them on ebay selling for a lot more than that, I still have one of these engines which I have got a race kart frame for, and I will be building it probably next year

[nswiss1975]

Awesome kart engine!!!!!!!!!!!

[pixuma]

ya know... i've run a few piston engines without exhausts (mobber cars) and over years of redlining i've never burned a valve... cracked a valve yes, burned no. this is because they get hot, i shut the motor down and cold air gets in and hits the valve, cracking it. i think thats what people mistake burning with

[nucleartractor]

Won't shutting it off before getting up to temp kill it? I heard some bad things like that about rotors, but never owned one so I could be wrong!

[aerobubb1]

no it won't kill it, they certainly don't like doing continuous short runs but that goes with any combustion engine, however thrashing a rotary engine before its up to temp will shorten the life of the engine considerably , I have two rotary cars I use every day and I take to the redline nearly everytime I drive them and I have never had any issues with them, I have killed nearly every piston engine I have had driving them in the same way I drive my rotarys

[aerobubb1]

Dude please explain to me how the lack of exhaust system is going to destroy this engine? Apart from emissions and noise I can't see how the lack of exhaust would have any bearing on the engines life span but I would love to hear your reasons so fire away and give me reasons or if I don't hear from you Ill assume your another self proclaimed engine extraordinaire that at the end of the day dose not know the rotor from the apex seal?

[smithz1983]

hey dont listen too him he obviously doesnt know how a rotor works. the less back pressure you have on a rotary the better unlike piston engines where you need some back pressure so you dont fuck up the valves

[aerobubb1]

At last someone with a brain!!!

[m4xwellmurd3r]

@smithz1983

back pressure is NOT good for piston engines. FLOW is. the reason why smaller exhausts work better on some engines than larger exhausts, is because the smaller pipes maximize exhaust gas speeds. The increase in speed increases power due to less pressure and also due to scavenging (as in, the exhaust pulses pull the gasses out of the cylinders) Bigger pipes=slower exhaust speeds=INCREASED back pressure=LESS power

[Texassince1836]

@m4xwellmurd3r some backpressure is needed for the exhaust valve so it doesnt burn. you dont need much backpressure, most engines have too much, but some pressure is needed

[aaroncake]

@Texassince1836 Yeah, lots of issues with exhaust valves burning out on those Wankel engines.

[rickforpresedent]

try using an exhaust pipe not hard to make

[aerobubb1]

exhaust pipes are for nanas!!

Try using some hard pills

[Tubeboy732]

As much as I hate to use an exhaust on my go kart, I'd rather not destroy my engine. Now if you got money to by more parts and stuff be my guest, but the engine sounds lovely

[TKDWolf]

You don't need back pressure on a wankel like that.

[Bobbymitchell10]

i have never seen one like that well this is the first wankle rotor i have seen run to

[sweetaction69]

LOL BRAP BRAP BRAP love that sound

[Triple88a]

hehe i like this thing, what did u take it out of?

[generator5500]

yeah!!! try on your own mower can cut 6 inches grass at 250 sq ft per minute

[tomistopdog]

That thing would look sick and sound so sick on a go kart or something. Be just like a mini 13b on a go cart.

[FiresWithWires]

were u get it an how much it cost

[adv20]

Looks like farting on a white sheet xD

[aerobubb1]

If your farts look my engine I would recommend seeing a doctor!

[SteffanLlwyd]

LOL!

[melsoftm]

where was this engine purchased?

[vicioustrees]

So cute!

[scott93257]

That's a neat little thing

[smounlasy]

That would be a perfect kart Engine!!!

[435ceg]

fukin A!!

[slymjim2007]

There is a kart engine out there, it makes upwards of 40hp and is practically dangerous to drive.

[SPTSuperSprinter156]

Nice little engine!

[bradhogan123]

nice

[IceDragon387]

yea seriously...where can i get one?

[foximissi]

22-30 bhp. savkel sp440 engine 440cc single rotor made by israel in the 70's. air cooled but have a conventional oiling system with a pump sump and oil metering injection. 7.6:1 compression,

[treborly]

few questions :)

how much HP?

how much does it weigh?

where did you get it and how much did it cost?

thanks.

[TommeyLeeReed]

Nice...What do you think about my rotary engine?

[aerobubb1]

A great idea with gas prices going up how much hp at what rpm? and how long can you get out of that tank at its rated hp? Ive seen similar engines on falklifts working in buildings great because your not gasing everyone out and when it goes flat you just change tanks or charge it which beats waiting for batterys to charge!

[abominableaussieman]

where could you buy a wankel engine like that? im in the market to buy one, i just dont know where

[buick455muscle]

What does this little rotary engine normally go into?

[aerobubb1]

great another gun crazed nutter, just what the world needs!! brap brap not bang bang

[peterban1234]

Your retarded motor just shitted himself.

[aerobubb1]

An expert ha? Unlike your camel rotarys very rarely shit themselves!

[xsyar]

jupp

[aerobubb1]

you can't they are 25+ years old

[hyperkinetic]

Is there a modern equivalent available? Who is building Wankel's these days?

[aerobubb1]

Yeah theres a few people still building them obviously mazda with the rx8, but apart from that theres wankel gmbh building cart and aircraft engines, I think moller still build them and there is another company building an engine called the RENNtech AIXRO xr50 a gocart engine, and os building the 5cc rc aircraft engine, they are making a bit of a come back as they deliver similar power to a 2 stroke but without the emissions.

[CubewanoLtd]

Cubewano!

[aerobubb1]

Nice engine! you guys got any jobs going? Im sick of working on turbines they just don't bring the same smile I get out of rotarys!

[kaupunkimoukari]

That air filter is horrible.

[aerobubb1]

If you don,t like it you will have to go back to using your mama's stockings as an airfilter you war crazed nutter!

[ultracomp2]

i know right. i mean like why do people say something. i mean like it wouldhave been better is kaupunkimoukari said something like " the air filter is horrible i think it would look better with (a different air filter with name or something)" other than justsaying air filter is horrible. awell. nice engine and fire up and flames out of exhaust

[douro20]

There is nothing wrong with that filter. It's much better than what was used with most small rotary engines (some had only a fine mesh screen).

[000darkstar000]

WOW!!!WAY COOL VID*****it's got Heaps good throtle Response!nice nd Crisp Exst2!wow cool!

[scavenom2008]

how many hp is that?

[aerobubb1]

about 29 from memory

[kasjv]

is it still for sale ifits on ebay still what the item number

[MadForM9950Cal]

haha great selling technique 'here is the engine.. this is a picture of me with my foot on it'

[aerobubb1]

And sold it no worrys at all! It was my foot that sold it I think!

[MadForM9950Cal]

wow. you have a magic foot :)

[acuraintegra101]

now how big is this motor and what is it for...

[aerobubb1]

Its 440cc and they were used on all sorts of vehicles and for industrial uses, things like ATVs and Ultra light aircraft, gocarts whatever you want really

[aerobubb1]

this engine is currently for sale on ebay
