I dunno too much about it, I found it on another forum when poking around google. I thought it would be cool to know that someone has actually done it. Prepare for the flamers! HAHA!

I don't think I would do it to my own bike, but does anyone have any more info?

WTF do they need a turbo for??? The bike is green... it's already fast enough. :p

Yeah, but its not BLUE!

...which would make it a good reason to turbo. :D

wow that's sounds nice.. i wonder how much more power is it getting..

Lol :)

Wow. Its a 250 geez.

Some people just like to tinker. I'd do it if I had the know-how and time just because I could. Trying to make a fast bike (600cc or bigger) faster isn't as much fun, or as challenging, as trying to make a little 250 spit out power. Though I suppose I should try telling that to the guy I once saw around here riding a Hayabusa with nitrous tanks strapped to it.
I'd really like to see the numbers from that dyno.

exactly...cuz it's green (ei. slow)..that's why it needs a turbo to keep up with other bikes color (esp black ones!!!) duhh!!! :D

Someone's gotta surprise at the next 250cc track meet. :D

If I had some turbo junk laying around the garage I might attempt it for exactly that reason only... tinkering. After all thats why I putging together the Honzuki project. Otherwise forget it, lol.

Yeah it sure looks neat anyways, I want to know some specs on that setup and some performance numbers, too!

I have an old friend who turbos everything he gets his hands on. Anyway, he found me at a track last year and tried to talk me out of one of the bikes. Claimed he could get 100HP out of a 250 with a little tinkering. Funny thing is, a 600 would still kill you, even with that HP. Would be a fun little project anyway :)

wow thats so cool! It seems like a lot of fun to do.

I was disappointed when i didnt hear a "woooooosh" sound when he let off the throttle on the dyno... :(

Yeah, doesn't really sound turbo... Need dyno results for conformation.

I don't understand how this person expects to be satisfied by putting a turbo on anything that tops out at 100mph...I guess it would be pretty insane at the track.

Change the gears?

Yeah, the RS125 is gonna kick there ass :p

that is sweet! i would be really interested to see the numbers as well. good thing too is that the insurance would still be really cheap.

I found his build thread... it seems that he was running the dyno with just the slip-on exhaust. The bike isn't completed yet, but ALMOST is!

as u can see the outlet of the intercooler is capped off which means...it isnt hooked up to the carbs so im thinking it wouldnt be makng any power
or does turboing a carbed engine work in some other way

He said he ditched the carbs and has a whole new engine management system. It is fuel injected. Pretty neat! However...I think that it would cost nearly as much as the bike to do.

what the HEEZY!? that is insane! and dope!

Yeah on a straight away.. but not in the corners :thumbup:

Soooooooooo true! The big perk of the 250! I get them suckers, and even bikes more than twice the size on the OUTSIDE of the corners ALWAYS! :)

Crazy people do crazy things, but great project overall.

wow thats alot of work...but its pointless cuz u would still need to have a pipe leading from the cold side of the intercooler to the throttle body or there is no way your creating boost, yor just making noise and actually losing hp

unless he did make that pipe and these pics are just progress pics

and I get flamed for bringing up putting a stereo on the 250:nerd:

Actually I was just thinking about the possibility of doing this earlier this week. Convinced myself not to because of time involved. I found small turbo chargers like that on ebay. Glad someone did it. I wanna see charts too.

Heh as I said on the other forum about this:

"I hate to say it, but that whole build might look nifty, but won't work. For one the turbo is wayyyy too big. It won't pass the surge limit until maybe 11,000 RPM. Once it produces any noticeable boost, you're redlined... The intercooler is ginormous. Can you say pressure drop? That and the plumbing on that intercooler is retarded so you're going to get a big pressure drop in all the plumbing. By the pictures it's not nearly complete as the charge pipe to the intercooler is there, but none of the plumbing to the throttle body is there. They don't show any pictures of the exhaust plumbing (probably because they haven't done it yet). The oil feed and return line is cleanly done so kudos to that at least.

Basically it looks like a professional shop, but I don't think they've ever played with turbos before or quite know what the hell they're doing. "


As for making 100 hp out of a 250? Yeah that's entirely possible. During the "Turbo-era" of Formula 1 racing in the 80's they were pushing like 70psi of boost out of something stupid small like 100ci engines (That's a little more then 1.6 liters)... Then again they were running some crazy fuel that wouldn't detonate under that much boost (which you can't get), the driveline could handle that (the 250's transmission couldn't handle that, the chain wouldn't take it, and the clutch would assplode), and the engines were built to handle that much power for one race (meanwhile you'd melt your pistons, lose your connecting rods, crack your head and instantaneously blow your head gasket all over the place, and don't forget that you have to COOL all that extra power somehow). THAT and if you're going to run crazy boost like that you have to realize that the power curve on turbocharged engines is scary sharp (VATN turbo technology is still very new and will never exist for a super small turbo :p ).

That's why after about a decade Formula One banned turbochargers all together :p The cars were scary and people tended not to live very long driving them :D . IMO anytime you're pushing over 1 BAR of boost with a turbocharger you'd better know what you're doing because you're in for a wild ride!

Now it needs a swimgarm like this bike to complete the excess...:eek:

Mmmm, turbo Ninjette. 100 hp is pretty unnecessary, but I wouldn't mind making 45 bhp at the wheel...

Yeah thats what I figured, 50% more seems pretty realistic, however awfully EXPENSIVE to get it all set up.

I'd be up for a smaller turbo. This one looks a little big for the motor. I'd also be interested in forged internals and a metal head gasket before I even tried. What about a bigger radiator? That turbo is gonna create quite a bit of heat!

ETA, VeX beat me to it on most of this... lol

Guess I should have read the whole thread. :D

Cool and everything...but useless without #s. This is really just a * tease otherwise.

It's been a whole year now... *yawn*

Why be such downers, at the end of the day its a cool upgrade.
Fixing things like small turbo's and inter coolers is all part of the job.
They never are perfect from the get go.

I say its awesome, they have a wr250 turbo on youtube it rocks hard.

I wouldn't knock it if they did it right :p There's no such thing as "fixing" an improperly sized turbo or intercooler... That's just bad practice in building engines (and REALLY expensive to boot). You select the right A/R turbo FIRST and then later when you're tailoring the turbo(s) can alter the wheels (which is considered FINE tuning). I'm all for turbo'ing things and currently own one-twin turbo'd car and a supercharged truck (I believe firmly in forced induction). Even if I had the correct sized turbo lying around I wouldn't fathom doing this considering all of the work you'd have to do to get the setup to work at all.

The other reason why this sort of project gets knocked on is the shear lunacy of what is involved to make it work. If you started with a fuel injected engine and wanted to push perhaps 10psi of boost... No problem (that's probably why people successfully turbocharge liter bikes all the time)! For this application they literally have to start from scratch and redesign everything. No thank you!

That's fair enough Vex, I agree with what you say.

However I think this may motivate others to do it properly, get one of the injected bikes from Europe.
Its still a cool idea, and deserves some credit, its a 250 turbs.

Hells yeah. If the Euro spec bikers toss a baby turbo on their bikes I'd be psyched to see the results ;) It'd be neat seeing the dyno curve :P

Almost as fast as a turbo Busa. Gentlemen, start your engines...

Sick.
