    Rotax and direct injection!

    Rotax 600 HO E-TEC is a great engine with great performances, but why the heck can't we profit also from this new technology????

    The 582 is a gorgeous engine too, but ways too thirsty, as it looks by almost 40% more then the 600 HO E-TEC.

    Re: Rotax and direct injection!

    Hi Erkki funny to find you here I was precisly looking for more info on this engine
    My concern about the possibility to put a PSRU (rotax gear C beeing the simplest) is the exit shaft , is it the same diameter / cone shape than other rotax (582...) ? gearbox must be put with crank gear
    assorted to gearbox
    also I see a crank seal which may prevent from making a adaptor to bolt between gearbox and engine case?
    (I see also that engine height is greater .. can it be reversed? )

    I belive this engine could be a good successor of the 582, but the engine data must be known like rpm egt and cht.

    I wrote Rotax, and they wrote me back, stating that a new block would be by far too expensive for them to develop, hmmm????

    But as far as I understand, this block had to be created as well, out of zero!!!

    Any kind of adaptions, for an psru, would make it look like a garage built system, and nothing I would like to thrust in.

    The unwritten message I got from R, is the following, that they are not interested at all, to bring a E-TEC engine to the flying community as they would like promote their new released spiderweb like 912 injected engine.

    The 600 E-TEC would be a serious threat to their own 912 series which just can't be.

    Hi !
    I just saw a picture with one of these daemonious mount , that's actually impossible to consider seriously..

    One candidate may be more likely , arctic cat f1000 , offering 5 bolting points (would it be enough ,their distance is not so much?) . and dual plug

    derating it by 100% (dividing power /2) would still offer 80hp
    Don't know weight...

    Still, coolest would be by far if Rotax could warm them selfs up to rebuild an engine block, based on the 600 E-TEC, for the flying community.

    But it's more realistic that I would meet some day Santa Claus, then that Rotax is going to build such a light 2-stroke E-TEC engine for us!
