Well I do not think it's like owning a Lambo..
it's nowhere near comparable if you ask me!

Let's try to get a car perspective shall we...

it's like owning a Brutus... oh you don't know Brutus I assume:
http://www.youtube.com/watch?v=wJn7LHE83cc

while it is possible to get it going and still stay safe.. you can go faster and quicker in a much safer way with a much smaller engine (say for example a Lamborghini )

take the 32hp gx390 mini stock engine for example that is in BirdFanatics mini stock car..
that on a kart like his can be quite a blast.. and since everything is in proportion it can be considered "safe fun".. go full throttle no problem.

A 120hp two stroke
-which if you ask me is much more violent than a 120hp four stroke like a mildly throttled cbr900 for example-
is something completely different.. the kart that should be build around that ..

let's keep a car comparision shalll we;
and let's be gentle and take 1968 safety standards (not todays)
so what you'd need to build would be equally well made and safe as a 1969 911 Porsche (110hp @6500 rpm)

if you can do that... go ahead!
if not.. go away!

Yes GiXXer Karts (99.5% power 0.5% control...) to me the guys that chop racekarts into gixxers are insane in a bad way.. that is pointless useless and still a better idea than to use a 120hp two stroke
oh btw I'd make a bet and nearly every GiXXer could be beaten on the tack with a standard race compliant 250cc shifter kart!

let me quote Pirelli: "Power is NOTHING without control!"

I repeat: please don't.
if you insist: please stay safe!

Just keep in mind: testosterone gives bad advice

Being a DragRacer<< Of bikes in Top Gas Class and run this engine GSXR1100<1340 piston kit with 150hp NOS Kit on top of that. And my dirt oval Kart runs a CRF450 Honda on my UltraMax frame. I think I can comment of power and control. I will say Jeremy is quite the TV clown . Sid some people are looking for the thrill of going a bit faster than 32hp can give. Some even like challenge of building some thing you can't buy. I can say your 32hp Mini Stock would kinda be in the way of your average Unlimited Open Class dirt Kart. If the man wants to build this deal . I am sure it's really no worse than same people who go out and buy BossHoss motorcycles or put Turbo's on the Hyabusa and want to see how quick they can go or how much power they can handle. Did I tell you I also own a Turbo street bike that makes a minuscule 225hp, It's every OldSkool Trubo Kit but it is fun wick it a bit once in a while. This all reminds me things the other kids in High school used to say about my 53 Chevy Belair with the 392 Hemi.

...as if dragracing and control belongs to the same sentence.
Karting is about steering.. dragracing not too much AFAIK

And you would want a parachute on a kart just to get it to slow down in the next quarter mile...
that could be quite impractical for a daily driver, don't you think?

Of course you can mount a 350hp turbocharged engine to a kart and call it a day;
but is that something you would tell Average Joe to do? on a DIY forum?

Me, I wouldn't!
And while thrill is nice, it's never safe (that's why it is thrilling in the first place )
Like welding without eyeprotection.. of course it could be done.. but should you??

Oh btw.. that 120hp two stroke engine will eat the CRF450 alive

it's not MY mini stock, it's Cameron's...
but since there's a race class just for those, I think that should be plenty of fun for starters

Anyways... whoever wants a Darwin Award is free to shoot for it;
but I wouldn't want to be involved in any advice given to do so.


So I'll just step back... nevermind me eating my popcorn

Back to the original question;
Correct me if i'm wrong here- not good with jet ski engines.
Aren't they cooled by water going through the WHOLE motor? I'm pretty sure water goes in, through the motor to cool, and back out. I think its pretty impossible to convert it to land, and if it is possible, it would cost a ton of money and time. You can buy a 500cc streetbike engine pretty easily with the money from that jet ski motor. It would be easier and cheaper. I understand the "I have what i have" mindset, but it's just simply not worth it.

I just wanna see a jet ski with a predator on it!!!!!!

Maybe you can use a long hosepipe to get water in while you are karting. Your range would be limited by the length of the hose though

Go kart tether ball anyone?

:toetap05::toetap05::toetap05:
I expected better from you two.....
It's just not feasible to hook it to a hose.....
Now, all he needs to do, see, is get a small trailer and put a tub of water in it. Attach it to the kart.... Then he'd have the first kart powered hot tub complete with water jet.... And it will cool the engine at the same time!
" what's that? You want more bubbles? Ok..... Throttle going UP..... "

Daily life lacks the thrills need to stimulate the Brain racing and going fast does. 120hp < horse power, that lacks control is useless as some one said. Darwin had his plants bugs and birds. Others need much more, and some can give advice on the dangers of stepping outside little boxes we live in . https://www.youtube.com/watch?v=j2cadiB6-NM < must be on your stupid list. the older we the dumber we are .http://www.google.com/url?sa=t&rct=...2G4QiSvpkoArRDQ&bvm=bv.74894050,d.cGE&cad=rja

@landuse
Even that wouldn't work! Pretty sure these motors need more water than that. It's fine to run them on idle hooked up to the hose, but once you rev it over a certain rpm the motor isn't getting enough water and will over heat. It would literally need to be hooked up to a hottub like Jim said, but the water impeller would need to be surrounded in water. So basically, for this work, the go kart would need a Hot tub sized tub behind it, with a hole cut out for the impeller, to suck as much water as it needs. So yeah, it would need a trailer and of course would still be shooting water out the side at a million miles per hour. Not to mention the fact that it would drain that tub in a second. Again, sell/trade for a snowmobile/dirtbike/streetbike etc.

 

[firemanjim]

We were being facetious.....
But, if the hose was big enough, and mounted to the intake properly, you could technically use my hot tub idea..... The return water goes back into the tub...... Not up in the air like you're on the water. That's why it would really be a hot tub. The water would just cycle back and forth, cooling off once it reaches the open air tub..... Passing wind could cool it off, over a larger surface area....... BUT still being facetious......

 

[fourtogo]

Wouldn't the Snogo Kart driver be dead before engine ever got hot Seriously. The Snow machine PWC use about the same engine . One draws water from running surface, the other circulates water through a radiator . I still believe the best compact all around high performance engine package is the Honda CRF450 or CRF250 at 53lb's it's nice compact engine. That's great thing about Karting you can do what ever you want build what want . And have the level of fun you want. Some are happy to buzz around with there Brig's other run a BGS V-Twin's or some thing different .

 

[firemanjim]

Boy I sure do love the idea of a crf450r under the hood of my '32..... My cousins bike is 60hp stock..... It will pull the front office the ground all the way through 4th gear, and doesn't stop when you get to 5th either..... Even in this big kart I'm building, that would be insane power. I GOT to have one......

 

[Poboy kartman]

Really. ...YoungGunwitha MANco....nailed it on this one....'nuff said......It never even occurred to me about the watercooled prob.....be he is exactly right. ....it's a matter of availability overriding logic.......as he stated. ...

This reminds me of the old Sesame Street song:....." One of these things is not like the others.......one of these things just doesn't belong.....can you tell me which thing....doesn't belong here. ....before I finish this song?"....

 

[firemanjim]

It's just not reasonable.... Didn't say possible, just not reasonable. Get something else that's more suited for this type of vehicle......

Snowmobile engines are pretty cool. Unique, fast and cheap. And if you have the tools to reuse the cvt that works great too. And if not then you make the 30mm-1inch shaft like a member here made quite long ago.
And yes, forgot to add in a couple lol's up there, and you would be right about the water going back in.

 

[ML-TOYS]

Does this engine also have the oil injection junk like resevoir and tons of oil lines like my jet ski had.

 

[fourtogo]

By pass all the injection and do pre/mix

There was a guy in mini sized T-Bucket that used to come to are local car-shows . That had a Merc-V6 250hp engine in it . I don't remember seeing any garden hose trailing behind the T

The mercury cruiser block can be used with automotive water pump, IIRC.... Isn't that one the ford derivative?
EDIT yep, that engine can be used in a car because it is based off a car engine..... All you do is swap the heads (iirc) and add a coolant pump,and radiator.
Fourtogo.... You just compared apples to watermelons.....
