    what a pitty, i still liked it but cant find dynacam back eighter, only this reference
    small airplane engines were used in patrol boats and some unusual designs i cant help admiring.
    above i was back with an under water augmented pulsejet, can think of some chances and was wondering what it would do.
    i favor the idea of a free piston or pulse engine and even a sliding bear cam may today do its time in a boat.
    guess only big multinational conglomerates that control politics survive these days wich nasa never was or isnt anymore?

    One of the entries in Ypisters link is pretty funny.

    I thought Indy rule makers flat out banned the turbines and AWD/4WD at the same time.

    I just ran across this old subject as well...too bad it has apparently disappeared. Here is some other reference discussions and photos for review.

    Thanks for that link....pretty nice slick presentation on that website...

    ....but look what just turned up

    Thanks Wscott52. I just found and read this rather long discussion that seems to lend credence to your warning.

    So even if the technology is good, it appears to not be in the hands of a viable developer.

    I always wonder about these magic engines and the web sites never show a bunch of them working anywhere
