You would need a fairly small turbo, and probably a four stroke motor to begin with, if that isn't what you already have. Most two stroke motorcycle engines use "reed valves" to control the induction of air and fuel into the motor, and I'm unsure on how well these tiny plastic valves will hold up to even a few pounds of boost. Also, u would end up with a very oily turbo, as a two stroke uses oil and fuel mixtures ignited together in the combustion chamber. It's a great idea though. Although a few of us have probably already tinkered with it... Good luck |

yeah that go kart is crazy i would like to no what engine is in it. Also with putting a turbo on a 2stroke engine doest work to well you would need to change the valves from plastic to metal and you would only be able to run a few pounds of boost. plus im unsure on what sort of compression the run so you would have to look into that because i have been told that 4stroke motorbike engines run high compressions. but i could be wrong |

Don't know how to do it but you must be able to turbo a 2 stroke. Overseas there are some 2 stroke diesels and as far as I know they are still turbo'd, but we are talking some serious truck technology here. |

It probably wouldn't work too well because the intake gases, being at a higher pressure than the exhaust gases would flow out of the exhaust port before it closes, because in a 2 stroke engine the exhaust port opens, then the intake port, then the intake port closes before the exhaust port. |

A standard gearbox race kart holds the lap record and the fastest top speed at mount Panarama in bathurst...top speed 320kmh. |

2 strokes dont have an oil feed for a turbo which mean sur turbo would last about 5 minutes! unless u could set up somke sort of external container which pumps pil into ur turbo and then cycles it back to ur container. i know of a mate that put a turbo on a scooter and only got 2psi out of it and didnt really feel strong |

[right][snapback]4967192[/snapback][/right] actually it's a GSXR engine hence the reason they called it the gixxxerkart |

Forced induction system works in the priciple of presurising the combustion chamber. This works well in a 4 stroke engine simply because they have seperate intake strokes and exaust strokes. During the intake stroke only the inlet valve is opened and the exuast valve is close. Where presurising the combustion chamber is possible. |

Where presurising the combustion chamber is possible. However if you look at 2 stroke engines, the intake and exaust strokes are the same stroke, meaning the exaust port and intake port are open at the same time. Exuast takes place when the inlet gas (with fuel and air) forces the burnt gases out. Meaning, there is no point in forcing fuel/air into the chamber. The forced fuel and air will just exit at the exaust port, thus the chamber is not presurised at all. [right][snapback]4971093[/snapback][/right] Not neccessarily. The turbo just won't be as efficient. You also get a gain in that the system will push all the exhaust out of the cumbustion chamber which is a problem with 2-Strokes. You can also run the turbo by greasing it instead of oil. |
