Scooter???
 

Can you turbo a 2 cycle 70cc scooter? I got a 02' Peugeot speedfight for free.

Re: Scooter???
 

It wouldn't be easy, I've seen plenty of discussions about this on moped forums and have not seen one person do it yet.

Re: Scooter???
 

get the smallest turbo you can find and go to town...it can be done

Re: Scooter???
 

How do you prevent the boost from blowing the fuel straight through the cylinder then?

On a typical 2-stroke engine like this the intake and exhaust ports are open at the same time at certain points.

Re: Scooter???
 

forget turboing it and spend your time making a real big, nice, efficient expansion chamber for it

once you understand them you will realize that its like forced induction in some aspects

Re: Scooter???
 

Ok I'm waking this up again. I just found out the scooter is 4 cycle and runs off a carb which has been upgraded to a stage .

Re: Scooter???
 

turbo that bitch. really it is a carbed 4 stroke its not hard.

get the smallest turbo you can find, probably something of a jap Kei car. blow the boost through the carby, just make sure all your seals are good. AFAIK scooters use gravity fed fuel, you'll need a high pressure electric pump, with a return line from the carby back to the tank.


this is basically it, just have fun tuning it

Re: Scooter???
 

Hey where can I get these fuel pumps? And do you have scematics for that? I also found a Daihatsu turbo which is a smaller then the kkk03 it probably only puts out max 6psi, This project will ssoon be done.

Here are the spec on the scooter

2000 something Peugeot Speedfight
50CC engine converted to 70cc
Stage 3 piston
stage 3 block
stage 3 tourque converter/ rear pully
stage 4 Carb
Stage 4 Throttle
Stage 3 Ehaust and intake
Stage 3 ignition

The guy I bought it from put around 1700 euro ( $2000) in tuning into and raced it on the street. This thing beat my buddies modded 00" civic ex heavly NA modded in a race. The guy also said the piston is forged but on the High compression side, but I think it can take a little boost.

how much hp does that scooter have now?..
its not really possible to turbocharge one with less than 30-40 hp
there is no small enough turbo..
i have made some research on this cause i have a 200cc 16hp and found the smallest turbo ever an ihi rhb3 and my motor is not big enough to spool that turbo...

Re: Scooter???
 

I'm not sure but I know it that hes nearly tripled the original horsaepower. I could use nitrous to spool it, just a thought.

Re: Scooter???
 

yes nitrous could help it..
but the ihi rhb3 is for applications with at least 45 hp
so if you can get out of your engine about 30 hp without the turbo using nitrous you can use the turbo
but the question is will the engine be able to handle that
if you think so do it

Re: Scooter???
 

I believe so. He put all forged internals and a bigger carb. I think If I run it on the rich side it will be ok ( not a pro at this ofcourse). ---- it it's free.

Re: Scooter???
 

Moped forums? Didnt know they had those, and um........why for are you hangin on the moped forums? You are an odd dude.....

Re: Scooter???
 

I didn't know that until he told me either.

Re: Scooter???
 

Because I live on a big campus, and a moped is the easiest way to get around. I've had a couple, and naturally I want to make more power out of them. My current moped smokes all the haters O0

Re: Scooter???
 

Does yours have a variator or an actual geared transmission? Peds with variators (Spree, Razz, all the gay ----) beat me off the line with ease. But once I shift into second and get up to speed it's not even close.

Re: Scooter???
 

O.K. These are my reasons to believe that your a dreaming kid.

1)It goes without saying that every modification possible has Stages 1,2,3,4.
2)A 70cc Scooter is faster than a tuned NA '00 Civic
3)Stage 4 carb, Stage 3 Throttle???
Finally, 4) You want to turbo a scooter, and use NOS to help it spool.

;D

Re: Scooter???
 

Honestly I know it sounds a little off the wall but I'm not joking around. This kid put a ---- load of money into this thing. See Europeans are crazy about these dam scooters and tune the piss out of em. I'll take some pics, to prove it.

Re: Scooter???
 

heck yea madison has tons of mopeds.. theyre everywhere, here at uwm, we have like 4...

Re: Scooter???
 

Well I'm in germany right now but I'm going home to chicago in agust. I could probably take it apart and ship the bitch. We will see >:D

Re: Scooter???
 

oooooooo i want one ;D

Re: Scooter???
 

If you find one I would take it apart and ship it without a problem
