Turbo Vespa
 

hope it's not a repost because if it is, I guess you'll have to go ---- yourself now won't you?

Spools up like a single turbo MKIV Supra!

Re: Turbo Vespa
 

lol, 42whp... i bet thats fast ;)

Re: Turbo Vespa
 

i would rock it to work. maybe even the freeway :-X

Re: Turbo Vespa
 

LOL badass :6

Re: Turbo Vespa
 

42whp would flat out haul some major ass. A regular scooter is what, about 3.5whp?

Re: Turbo Vespa
 

What ever happend to whitey's turbo banshee? :P

Re: Turbo Vespa
 

Best video EVER! :8

Re: Turbo Vespa
 

Did you see the Piramid in the back ground?

Re: Turbo Vespa
 

jeff, my 250 has about 45 hp. so think of what it was liek to ride my bike, and apply that to ascooter. ------ badass.

Re: Turbo Vespa
 

hahahha i want one

Re: Turbo Vespa
 

im pretty sure a banshee engine would melt with a turbo on it within the first boosting. that vespa doesnt have as much to worry about since its ports are extremely small and it has extremely low compression. i also do not know the specs or boost level of the vespa either its probally 125cc , a 125cc mx bike makes 35 or so horse so its probally bostling low maybe 3-4 psi. either way it would not last for long. this is why turbo snowmobiles are 4 stroke not 2 stroke.

Re: Turbo Vespa
 

dude your crazy, a 125cc 2 stroke bike makes around 29-30 hp. stock

that vespa even though its 125cc it doesnt even make half of that, its air cooled non reed petal intake design, low revving, its a piece of ---- basically. they must have either done a shitload of internal work, or they are lying

Re: Turbo Vespa
 

i was talking crank horse. i belive the vespa is a crock honestly i will retarcat my beliefs after evidence is displayed that it is true.

Re: Turbo Vespa
 

Ha ha ha.That is ------- great.Pure HMT material right there. :y

Re: Turbo Vespa
 

i would rip that little fucker up.. ------ bad ass right there

Re: Turbo Vespa
 

people do that all the time in greece. its not uncommon to see them hang with bigger 400cc motorbikes, untill you reach like 120 and the wind resistence is soo great that you seem to be messed up with bugs.

iu recal reading a mag article ( in greek ) with a 50cc engine thgat pumped out 50+ bhp. it was on a mini drag bike though.

Re: Turbo Vespa
 

when you put it that way that is kinda fast.

Re: Turbo Vespa
 

Remember the goped vs nitrous'd WS6 video? I calculated it out to the goped needing 23 whp to hang with the 400-450 whp WS6...

Re: Turbo Vespa
 

so what? that thing looked doggy as hell, your bike has great mid range and torque.. theres no way that vespa will be lifting the front tire off the ground with that powerband.

Re: Turbo Vespa
 

What do you mean whatever happened to it. ??? Right now I'm looking for someone to make flanges for the turbo. You also have to remember its not just slapping a turbo on it. ::) I handbuilt an entire fuel injection system from scratch, helping to create code for timing control from a stator since there is none around, designing a charging system for a bike that didn't have one, and making an self-contained oiling system using the swingarm as an oil tank. It'll take as long as it takes to get it right. Also, I haven't really had time to work on it recently becuase its not my top priority in life. Pics: http://www.hmt-tv.com/hmt/matt/Banshee/




You smoking crack kid. ::) A Banshee has 6.5:1 compression stock, it doesn't get much lower than that. Also my Banshee has forged pistons in it and so does almost every other 2-stoke that gets rebuilt once.

370cc 175rwhp and it doesn't "melt." Try that with a 4-cylinder. :-\:

And snowmobiles are 4-stroke cause tree hugging hippie faggots basically made the 2-stroke motor illegal so noboby is making them anymore. Don't talk like your an expert on the topic when you obviously have no experience with what your talking about.

Re: Turbo Vespa
 

amen brother matt. 2 stroke for life.

Re: Turbo Vespa
 

now that's pimp. 175whp I did not know that. That's ------- nuts.

Re: Turbo Vespa
 

whitey have you figured out what you're going to do to oil the turbo.

i was thinkin you could find a oil passeger and tap it through the block or head

Re: Turbo Vespa
 

2 strokes dont have oil passages johnny. the head i sjust a dome with a coolant passage and a sparkplug hole. the jug is just s aleeve with the water jacket/powervalve assembly provided you have one.

the crank has no oil capacity, it draws in the gas in the intake stroke into the crank and the premix lubes the assembly. the tranny is a self comtained unit.

how many quarts will the stock swingarm hold? im curious, sounds like a descent idea provided you dont plan on much serious offroad action.

Re: Turbo Vespa
 

Yeah I'd be worried about sloshing unless you put some nifty baffles in there. What kind of oil pump do people use for these kind of setups?

Re: Turbo Vespa
 

oh yeah i forgot it was a 2 stroke :S

i put some thought into it, i was going to do it on a 4 stroke 250cc 3 wheeler, but i never got the 3 wheeler :/

Re: Turbo Vespa
 

the snowmobiles im talking about make 250+ horsepower and they use 750cc and up street bike engines. the reason 2 strokes are made low comprression is because it fires every single time the piston comes up and it really only makes power mid to high rpm . a bottom end in a race bike will only stay strong for 35-40 hours before it starts to loose a lot of power then it blows its cookies. so your telling me its worth it to turbo a 2 stroke and have it blow its cookies on 5 psi and you have to do it all over again. i bet a banshee engine would not be able to spool a dinky turbo and with no expansion chamber it would deffenately run shitty and have a very short powerband. if its all that much worth it to you then go for it. a 600cc streetbike engine would most likey outperform the turbo banshee engine and outlast it by 80 times and you could boost it and be faster than you ever need to be.

Re: Turbo Vespa
 

i beg to differ, a turbo banchee would rape up on a banchee with a 600cc crotch rocket motor stuffed in it.

the banchee has a power stroke every other stroke. 8) hes running wiseco pistons and im sure a pair of hotrods. hes good to go.

Re: Turbo Vespa
 

2 stroke= :y

Re: Turbo Vespa
 

i give the banshee 5 hours on boost

Re: Turbo Vespa
 

To a point yeah. I have a sidecover from an RZ350, thats the street bike that the Banshee motor came from. It has an oil injection system on it. I'm using the gearing from that assembly to spin another higher volume oil pump. the only thing I don't know is which pump would be the best to put on their. The oil pump is like step 10 of this turbo project, right now I'm worried about step 5. So one thing at a time. ;)



It'll easily hold 2 quarts without a problem. With baffeling it should be no problem for serious off-roading. I mean most swingarms are hollow inside anyways so might as well use that space. Therefore the swingarm will be as strong as stock.



Wow, are you just making ---- up as you go along? ::) With no expansion chamber a Banshee motor won't even run. ::) A 2-stroke has double the exhaust energy as a 4-stroke so a 350cc 2-stroke would be comparable to a 700cc 4-stroke. Yeah, its really going to have shitty spool time compared to a 4-stroke. ::) A GSXR 600 has around 100whp and thats what I'm shooting for with low boost and I can easily pick up my Banshee motor with one hand, can you do that with a GSXR600 motor? ::)


Well you already proved that you have no clue what your talking about so what you think really doesn't matter does it?

Re: Turbo Vespa
 

Nice Faggio

Re: Turbo Vespa
 

You guys are making me want to turbo my CR500. But I think it's fast enough for me as is. ;D

Re: Turbo Vespa
 

Im throwing the bullshit flag 10mi's. on this. >:D I've seen plenty of turbo banshee's run for a long time. Thats when they're burning up and down sand mountian all day long in 100 degree weather. lol, literaly, people beat the ---- out of those things and they dont like to give up.

2 STROKE 4 LIF3!


Sorry I didnt put my last 2 posts into one. im lazy i know. :8 - "so sleepy"

Re: Turbo Vespa
 

i give it x amount of time running with the boost

x = time till needs rebuilt 8)

24 hours of riding? :P

Re: Turbo Vespa
 

Maybe, even if though, those engines are ------- cake walk.

Re: Turbo Vespa
 

whitey i was referring to you needing to put the fitting to draw oil from the swingarm near the axle. and on the bottom of the swingarm a rock or some ---- will rip off the an fitting an then your turbo goes poopie

Re: Turbo Vespa
 

You can get 2 stroke snowmobiles still, but everythings going to 4 stroke. watercraft, snowmobile, atv's, dirtbikes. and im sure the turbo banshee will be fast as balls. But not quite as fast as drag snowmobiles. and street bike engines? wtf? thats a hell of allot of machining for the slider clutch and the engine break and to even fit one of those in there when polaris already makes turbo 750cc 4 stroke motors, and 900cc 2 stroke race snowmobiles.

Re: Turbo Vespa
 

I think thats longer than the manual gives a stock banshee motor until it needs a rebuild. My Banshee will be like your Mustang's gas mileage... turbo it and engine life increases. :S

:P


Have faith in the master plan. I wouldn't build something shitty. ;)

Re: Turbo Vespa
 

That is sweet, scary fast.
