  • first off I love it. 2nd, I have been looking to install either a snowmobile 1000cc triple, or a PWC 1200-1300cc get ski or an outboard motor into my old SAAB GT850 triple.

    I have been trying to find info to no end. You guys would perhaps get back to me so I can get some info?

    Heres my youtube page. Please contact me. I'd love to talk.

  • am i the only one who saw 2 stroke v8 and thought it was a detroit diesel?

  • people need to understand that if you got a 10 hp motor with 20ftlb of tork, with 5/1 gearing, you could have a 9 hp motor with 25 ftlb tork and 4/1 gearing, the 9 horse is gonna go faster...it's not all about horsepower and torque... its about the engine, transmission, drivetrain, and how they all work together...

  • just get a victory bike engine with a turbo...it would sound sweeter

  • @egotripband what the hell?

  • A 4 stroke has less torque than a 2 stroke of the same displacement. The only reason why people say 4 strokes have more torque is because they are comparing engines of different displacement e.g. (250cc 2 stroke vs 500cc 4 stroke)

  • @jalit wrong

  • marine engines are de-tuned so much if you use them you would know that also evinrudes are work horse engines they have the same torque but less rpm only because there de-tuned more then mercs i could get into the reasons and the parts that where used but i wont the fact is these are work horse engines more so then mercs and Chrysler and they where tuned for workinging hard not for a car- tune it up and rip

  • Thats why there will always be be 2 - strokes!!

  • Guys dont forget they're measuring the hp at the rear wheel not at the crank.

  • i think you broke the dyno

  • If this engine would be a good one liter of power than the 125 cc Motocross bike, which has about 40 horsepower, so this should be a 1152 horsepower, so the power does not go much out of it. Understand the two-stroke engine exhaust pipes of the importance of! They can affect much more than a four-stroke engine.

  • @Topsiekku you cant always get another 40hp by adding another cylinder of the same size, you lose power as the force required to turn it becomes higher. I've heard rumours of the 125GP bikes making 60HP on the crank and the 250GP bikes making 110HP on the crank now make that 3.6L its never gonna happen. plus did you see the torque numbers! thats insane for a 2 stroke

  • @Topsiekku 1152 hp? go back to school.

  • Never install a two-stroke engine direct a big pipe!

  • problem is that marine motor are so detuned for reliability. but with the right setup that thing would RIP.

    expansion pipes, bigger carbs, milled heads and a port/polish will boost the power through the roof.

  • @Turbojeep23 Marine motors are purely tuned for torque. If i'm not mistaken, evinrude v8's are fuel injected.

  • the computer con't hand it looool

  • i've found my new ringtone ! the new strokes are out to bring life into the world,cant wait,i got a nice enough hybird stroker ,but ,sick n twisted 2 stokes like this are something ,real bikes,if ya cant ride get off ha ha

  • i've found my new ringtone !

  • ya dont just make a fine chassis, and slam a boat engine on it...

    for practical issues , marine power-plants are rough and got heavy parts,

    this causes NA engines to hold, or restrain its potential, for some reasons, i remember 2,

    first is the constant mid-high RPM leves which they are submitted, so theyr made to last doing that

    second is the amount of torque needed, diff from a car/wheel vehicle needs, so there are not light weighted moving parts, since inertia of the propeller is the key

  • haha the 2 stroke molested the dyno test

  • wow only 200 hp from a 2 stroke motor. and a 2 stroke v8 at that. you should have way higher numbers

  • @mxkid1000 That's a boat motor. I dont know how big the cylinder volume are, but 200hp from a boat motor is pretty good. I'm sure they can get more horsepower by building exhaust pipes that are better matched

  • @Adde085 the pipes would be matched to the port map for engine efficiency, you'd have to change all the characteristics of the motor to make a whole lot more power and with this you would lose loads of torque in the process

  • used to be a v6 outboard in a buggy near here bout 20 years ago. i think it was a mercury. aparently it was wicked.

  • Awsome. Never even thought of using one of those!

  • why r the stats all over like that? lol

  • bhp?

  • What transmission did you use for this car?

  • this engine in a RX7!

  • @kardinaalpwnd The RX7 was a rotary engine, not a 2 stroke.

  • @Carlar788 no shit sherlock! I was reffering to putting such an engine in a RX7 FD3S. Low weight to keep the the balance intact and the sound it makes just makes me jizz my pants.

  • @kardinaalpwnd just shut up. youre retarded.

  • The poor man's F1

  • pep boys dyno machine??

  • That sounds awesome - like a formula one car but better.

    2 strokes are amazing engines.

  • Dyno fail... :)

  • @DoubleM55 i know if its an marine engine why not take to a marine shop, tune it then dino??? retARDS

  • Lol @ dyno thing XD

  • ur power curve is messed up! -408 hp

  • ur power curve is messed up!

  • Where is 2 stroke exhaust pipes?

  • Best sounding engine EVER !!!

  • Sikc!!

  • boat motor for the win! :D :D :D!!!!!! lol thats fucking brutal!

  • wow this is AWESOME!!! I have wanted to do this with a Mercury V6 for a long time

  • Is it on its side?

  • i dont get this dyno? what kinda numbers is it pushin out?

  • i wanna see this thing in action!

  • why hasnt anyone built a scaled up honda cr250 motor V8, for a car? how hard could it be with computer drafting. reed valve tuned pipes in a car.......evinrude is a piston port design the piston is the valve just like a 1998 indy 500 snowmobile no tuned pipe.

  • hell yeah this sounds great in high rev area

  • its sounds like a v6

  • I think that engine sounds better that 4 stroke v8's

  • @sam those power stats where at the wheels so more like 320hp and 420lbft at the crank.

    @laz your right I bet that whole engine weighs at or under 400lbs. A 3.6 4stroke 6 or 8 would need to be dohc to make that power. and said engine would easily hit 7or 800lbs

  • @beavistechrock i think you need to look up how much an ls1 v8 weighs.

  • @beavistechrock

    you think DOHC makes instant power? I think it only makes prestige.. take a closer look at OHV or SOHC. Those systems actually have more advantages than disadvantages over the DOHC. DOHC only makes it "sound or look cooler"

    don't make me proove you this..

  • @ht666th On a stock engine dohc is useless. One cam can easily drive the same number of valves as a dohc. When you have a modified engine, with heavier valve springs, sometimes dohc is needed for the strength to drive all those springs at without breaking, A sohc can may not be able to do it. In stock form, sohc definitly has the advantage of less rotating mass.

  • i seen a 750 2 stroke engine in a bike put out 165hp!!

  • i know 2 strokes are twice as strong as 4 strokes coz they have twice more power strokes ...220bhp is extremly weak

  • Not true. Much of the power produced by combustion escapes out the exhaust as well as some of the intake charge. The power band is also narrow due to that fact. That's why the exhaust must be tuned. They do rev higher without the valvetrain draging it down or having valves to float and produce horsepower that way but when it comes to crank torque they have nothing on a 4-stroke. The only advantage a 2-stroke has is power to weight ratio.

  • @lazzer408

    actually single cylinder 2 strokes have the advantage of "any position" that means you can run it upside down. wont happen with 4 strokes. and the intake charge only escapes for gasoline 2 strokes. everything that escapes in 2 stroke diesels is more air from the turbine which isnt such a loss as fuel.

  • @ht666th There are string trimmers with 4-strokes that run in any position. More complicated sump ofcorse and not a very demanding application but they do exist.

  • @lazzer408

    could be but the sump must be pretty fancy. thus when shutted down in upside down position the oil tries to leak through piston rings into the combustion chamber. two strokes (single cylinder) have the same stuff in both sides of the piston. two strokes are also smaller cuz they dont have heads (for multi cylinder not so big heads or so many cams). thus the valvetrain (if it exsists) is not so complicated and doesnt take away that much horsepower.

  • @ht666th They may have to be stored rightside up. I have no idea of that. They run any direction though. Same with RC car and Airplane 4-strokes.

  • @lazzer408

    its possible that they RUN in any position but things get different when they lie left somewhere.

  • @lazzer408 "but when it comes to crank torque they have nothing on a 4-stroke. The only advantage a 2-stroke has is power to weight ratio"-nope. if the displacement is the same a 2 stroke produces more hp and tq compared to a 4 stroke-hence the need to run a 250cc 4stroke against a 125cc 2 stroke to be competitive in motocross. on top of that the 2 stroke has a better power to weight ratio(as you stated)and is much cheaper/easier to work on.

  • @304teddy Not torque. The torque is provided by the gear box. Which is why I stated CRANK torque.

  • @lazzer408 doesnt matter where you measure it(at the crankshaft or the wheel)2-strokes make more torque period.

  • @304teddy With a statement like that it's clear you don't have a very good understanding of mechanical devices. A 2-stroke has a very narrow power-band. In the middle of that you could say the 2-stroke's ve is at it's highest. At that peak torque, the 2-stroke can be geared (usually in the primary reduction between crank and clutch basket but also in the transmission) to produce high final output torque. The 4-stroke, on the other hand, produces torque across a wider band. and I'm out of letters

  • @lazzer408 with a statement like you have no understanding of.mathmatics. 4 strokes have transmissions that multiply tq the same as a 2 stroke. Fact is a 250 2stroke makes about 10 ft lbs MORE than a 250 4stroke measured at the crankshaft beforei any trans effects tq. is that simple enough for you to understand? 4s have a wider tq curve but certainly not more.

  • @304teddy A 2stroke might have higher -peak- torque at a very narrow band. Average it out and a 4 has more. I'm a 2 stroke nutcase dont get me wrong. I'm about a 12 pack away from sticking a yamaha 700 tripple in a Suzuki x90.

  • @lazzer408  Loving the x90 idea haha

  • Comment removed

  • Dude the dyno stats look like they gave a retard a crayon.. lol

  • @1977xl75

    or gave it to michael J fox

  • LMAO doodeedoodee ! that's what i called a retarded amount of power!

  • i was about to say, the tac is off, and then they posted the message lol

  • Comment removed

  • @1977xl75 hhhhhhaaaaaaaaaaaaaaahahaa

  • @1977xl75 haha

  • @1977xl75 after reading this then watching the dyno stats appear made me laugh. haha

  • yeh it would be a night mare to make individual expansion chambers . As this is where two strokes can make or loose lots of power ,and thats through the exhaust .

  • Maybe my eyes are failing, but @ 3:00-ish, The dyno screen clearly shows only 226 tq. and 149hp max @ about 5k rpm's. From 5000 to 7600, the power curve(s) drop like bricks,- but it sure sounds cool !

  • It sounds mean, but 220HP from a 3.6L 2-stroke is very very weak imo.

  • these were supposed to produce 300 hp at about 4800 to 5000 rpm......at the prop...if it were on a boat......

  • Your the expert

    I'm not worthy

  • Sorry?

  • Tuned pipes connot work on these, because the exhaust ports on each bank are all connected internally. Mr.Raceylnd seems to have the exhaust figured out nicely.

  • That sound is downright scary !!

  • HAHA a boat motor in a car first time i seen that also it needs tuned pipes to make it run better not straight pipe as it will cause low performance and damage the piston and rings more

  • looked like a tuned exhaust to me...

  • i like how most of these guys think they know better than the designers. im sure when they built it they thought about the exhaust. go back to playing excite bike and maybe tell your mom your ideas

  • what did i say?

  • oh man im sorry im dumb and i hit reply instead of post a comment sorry

  • Comment removed

  • the computer is like" ah wtf is this?? it hurts ahh"

  • That doesn't sound at all like a 2-stroke engine. Shouldn't there be 8 individual exhaust pipes and a lot more rpm and horsepower? And where's the smoke?

  • Yeah, I bet thats the reason the power falls off HARD in the high rpm, he needs the expansion chambers like 2-stroke dirtbikes to make any power. That exhaust wont even let the engine rev!

  • why do you say that? have u ever heard any v8 that sounded like this? or have u even heard a s troke v8 for that matter. you do not need each individual pipe, my 600 triple sled has a 3-1 header into one tuned pipe.

  • With proper exhaust you'll get out much much more power.

  • What do you mean by "proper exhaust?"  Are you saying this bad boy needs some expansion chambers? I figured that, because it's an Evinrude engine, it's probably got DFI so the expansion chamber isn't really necessary.

    Maybe you had something else in mind?

  • @vooteleaer an individual expansion pipe for each cylinder or something like that?

  • @moptim Yep, that gives the engine it's full power

  • @vooteleaer No doubt!

    

  • @vooteleaer i dont think this guy need any advice from you on power

  • @hitbythese A two stroke will benefit from a proper expansion chamber. He's right.

  • now that is a badass sand rail

  • how many ponys?

  • prolly less than 200.

  • it said. Consistent 220ish.  pay attention.

  • that is straight up beast!!!! it must run great in the dunes.

    and for everyone asking why?

    he is lighter now, higher rpm's, and better fuel efficiency

  • 2 stroke epic win

  • Your joking....

    a 2stroke V8?

    why?

  • Why not?

    Now that I don't have to worry about emissions anymore I would do that to my 81 toyota pickup just to be the first and only kid on my block to have one.

  • lotus is making a 2 stroke motor idk when but i know for a fact that they are going to do it

  • sounds cammed at idle

  • it doesent have a cam...

  • i know but because of the 2 stroke it sounded like a cammed 4 stroke v8 to me.

  • i get ya, one extreme cam i would say lol

  • bro idc wat anyone says, in my opinion 2 strokes are the shit, 4 strokes are ok but just less exciting when they dont have a powerband likea 2 stroke...and there engines are way easier to maintain

  • that engine is actually the powerhead off a johnson ocean pro v8 or a evinrude v8 which were the same outboards. they were the quickest outboards of there time by a long shot compared the the 2.5 litre mercurys and still are the quickest outboards avaliable for there weight,

    awsome engines. last well if there taken care of. very hard to come by now. that was one of the best looper 2 strokes of all time. another ridiculas amount of power to be gained if he runs expansion chambers too.

  • looks like a 4cyl to me, sounds like one too

  • but dont get me wrong i still love two strokes like my 01 yz50,my 04 pw80 and my old 03 kx85 but my crf150rb is the best and fastest of them all

  • thats a fucking lie,four strokes make way more torque but less hp,and to tell you you the truth 450 four strokes are faster than 250 2 strokes,four strokes have a lot less problems the 2 strokes and they have lower emisions and tell me who still makes two strokes...nobody the last two strokes made were yamaha's 2009 yz125,and my stock crf150rb is faster than stock 125s and it weighs just as much as the 125's

  • actually my friend got beat by a yz 125 on his crf 150 and both of the bikes have no mods

  • my 04 kx250 would always beat my friends 05 honda 450 no mods to either

  • Are you kidding me loganexploding??

    So you're telling me that a YZ250F (for example, insert CR/RM/vagina) makes "way more torque but less hp" than a YZ250 two-stroke?!? lol you must be confused, two-strokes make a lot more power and tq than a four-stroke of the same size.

    And four-strokes have less problems? WTF are you talking about!! They have so many more moving parts internally, you obviously have NO IDEA WHAT YOU'RE TALKING ABOUT.

  • most 4-strokes are more reliable, have more, less horsepower and are usually more efficient.

  • exactly craig1360, drz400e332 ur a tool........dont be a spanner mate ur name even has drz in it u should be supportin the four strokes sice u in the brotherhood lol

  • thanks,lol just speaking from experience, my 50cc 4-stroke did 10,000km including been hammerd down hills and stuff and it never missed a beat, my friend got a 50cc 2-stroke, derestricted it, up jetted the carb and a few days after it seized and im talking about a £3000 bike here

  • so 4 strokes are better, but it takes a 450 to beat a 250 2 stroke?

  • i kno eh lool i dont get that ether

  • your a dumb fuck, what are you 10, still riding a crf150

  • 150??? yeh man bit much for a 10 year old dude.

  • thats easily the best engine ive heard and seen!

  • dirty bird!

  • how many db does that reach?

  • Just so you all know two strokes do make more power and torque. I have a 1000cc two stroke triple in my Arctic cat snowmobile and it produces 182hp stock. And it does this at less than 9500RPM's now a 1000cc Yamaha snowmobile four stroke produces 150Hp and it has to rev to 11000RPM's to make it. Trust me two strokes eat four strokes any day. And yes they have been running 400cc 4 strokes vs 250 2 strokes in dirt bike racing.

  • 450cc 4 strokes lol

  • yeah man, 2 stokes all the way. i take it you have a tcat 1000. i got a '93 tcat 900. i just gotta get it runnin. the previous owner burned a hole in the middle piston. 2 strokes are much simpler, lighter and have less moving parts than 4 strokes, not to mention twice as many powerstrokes per 1000 revs. its good to see someone else who knows what theyre talking about.

  • i agree with eveything you said

  • two stroke is more powerful But it is less efficient, cuz of the way the engine works, if that makes any sense lol. i do love the noise and power of two strokes tho :D

  • sounds awesome, but for 200hp was it worth it ?

  • FUCK YEA!!! 2 strokes kick ass!!! and what in the hell were the final numbers!?

  • 2 strokes FTW!!

  • damn that thing is a screamer!

  • lol 2 strokes make less torque then a 4 stroke of the same displacement.

  • actually believ it or not 2 stroke make realy comparable torqu neumbers to a 4 st its just they make it over a smaller rpm range

  • What idiot told you that? You think an engine that fires twice as often is going to make less torque? No. In fact they make much more. Two strokes are usually made very small and tuned to make high peak hp instead of torque. Given equal displacement and equal state of tune, a two stroke will make much more torque and hp while being smaller and weighing less but do it while consuming much more gas. The ratio of extra gas consumed vs extra power depends on the efficiency of the motor.

  • hmmm ok,well iv raced dirt bikes for 6 years i also weigh around 90kg and i cant get enough of the four stroke torque.Now the fact is the four stroke bikes i have chop up my two stokes.The two strokes dont seam to have that torque that the fours do,even of same displacement

  • Most dirtbike 2-strokes are tuned to compete with 4-strokes twice their size, so they sacrifice torque to get more peak hp. Try a KX500 or CR500 though. They didn't tune them for peak hp, they tuned them for all over power. They make about the same peak hp as a hopped up 450 but make mountains of torque and don't rev very high (power drops fast after 7k rpms).

  • Nope you cant use them in the same class.The four stroke is a higher class and these bike have much more power then the two stroke class.I started on two strokes and dont get me wrong i liked them,very fun with lots of revs.But now i ride 4 stroke 400cc class and they have so much power,feals to me like torque as there isnt as much revs.They are called the thumpers,so much grunt insted of revs.Also i like that i can still see the track after a couple of laps,insted of a face full of oil

  • Guess that is why the bike holding the record for the fastest dirt bike in the world is a KX500 named the cardboard robot, second place is a 1981 KTM 495 ... two stroke. Google it.

  • Fuck google and the internet,most things on the net are bullshit just like wiki.Now i know for a fact we chop up the 2 strokes.but becouse i cant be fucked going over it again im going to let you have this one.ok.2 strokes are the best and car companys are just stupid becouse they dont use 2 stroke engines.Also Top Fuel has know idea becouse they use 4 strokes,they should use two strokes and get this so called "Double the power of a four stroke".(Sarcasim)Wake up cunts!!

  • Ever think maybe it has something to do with the rule books? Like that rule that says in the 450 class two strokes are limited to 250ccs... because they make more effing power per cc? All racing has rule books. Those rule books usually only allow four stroke piston engines. Rotaries, diesels, and two-strokes are BANNED from most types of racing. When they are allowed, it is only at ~half displacement of the four strokes. They limit them to half size for a reason! They make more power...

  • Mate you should have quit while you were ahead.Two strokes are not banned from drag racing,yes Top Fuel is it own class but there is no restriction drag racing aswell.They dont use them becouse your wasting your money on a two stroke drag car<rofl at that one.More mods can be done to a four stroke engine,how many 2000hp two strokes you see,none.Two strokes are good for there job weed eater,mower's and chainsaws.Even then they being replaced with cleaner and more powerfull 4 strokes!!

  • jakal is right.... the 2 stroke tq is made in the

    mid - high range... 4 stroke is low - mid

  • depends on the 4 stroke , now days stock stuff is getting higher and higher in rpms, check out ferrari,mercades ,formula1 cars - 4 stroke engines,2 smokers are awesome,plain and simple

  • i freaking want one ...lol the motor autographed the dyno screen lol cuz its that badass

  • i love 2 stroke's

  • lmao at the dyno graph haha its all squiggly

  • u need some proper expasion exaust on that, bet u'll get 25 more percent power i reckon any top buggy mate never seen a v8 2 smoke!!!!

  • you tripped out the dyno!

  • With individual expansion chambers this engine would be a monster.

  • id like to know how much that weighs. I wonder if the weight savings of that engine are worth it.

  • for a small engine thats pretty damn good power and the torque is awesome. and its not the same boring v-8 that every other car out there has now put a blower on it :)

  • at 3:02 it sounds like a F1 car

  • that is the beauty of the 2stroke :) there lovely engines xD no one likes them becuase they produce more torque than horsepower :/

  • That would be a power head from an omc evinrude v8 outboard made back in the late 80's, they came stock in either A 3.6litre 300 horse or a 4.0litre version.

  • i want to know where this engine came from..badly
