    I have seen that site before. They offer slightly to little info on products to really commit to it, but it would be interesting to have a crack at a fuel injection conversion.

    Hummmm Turbo charged, fuel injected 100. Not sure if you would get enough power with the 20mm throttle body. Will consult someone that knows.

    They offer right up to a 35mm throttle body.

    And you are right of course. Well that changes the game a little. So you could sleeve down, de stroke an FXR and wack a turbo on it. It would still need to be making 300hp per litre to be top of the heap. Coz for all the fecking around you would want it to rule the track.

    Must consult the oracle. Back soon.

    Apparently all you need is about 6K and you would have a lot of grunt.
    Fuel Injection, Computers, Petrol tank pumps, Turbo, Water injection system. Very strong engine casings. One day maybe.

    F1 qualifying engines used to run something like 75-100psi of boost and get around 1200-1500hp from 1500cc in qualifying trim (depending on who you want to believe)so no reason why you shouldn't be able to get 100hp from your 100cc engine
    "If you can make black marks on a straight from the time you turn out of a corner until the braking point of the next turn, then you have enough power."

    The engine is made, have an IHI RB31, have the Haltech ECU. Missing was all the suitable fuel system stuff. Now I know where to get it.

    Great plan sir. Now do it quickly so we don't have to wait to see what happens.

    No fecken way. Well done that man. Kev was saying it would be a good idea to use a bigger engine like what you have done. Also said they are getting 1400hp out of a 2l honda engine with 50lb of boost. So 70hp is possible if it holds together.

    Go for it. Look forward to seeing it on the track. For a 1/2 second each time I am lapped.

    Now all you need is the sidecar class to be rebirthed so you have something to put it in.

    Onlookers will note the 2005 stamp on the photo. When I first saw this engine it was a collection of bits probably a couple of years before.

    However I'm only just attempting to get my 15year MB100RS to the track so I won't cast too big of a stone.
    Don't you look at my accountant.
    He's the only one I've got.
