Scooter???
 

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

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.

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.

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

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...
