    Tony dukas waterbox

    I read some where a while back that a tony dukas waterbox can yield a 3 mph gain on the 1.8 sc ski`s!!! has there been any test that can back this up? i think it was actually done on a fx sho not sure.

    They make one. I emailed them about it. Guess they are in the process of making a few for customers now.

    3mph from a waterbox? I'll believe it when I see it. I don't doubt that letting the motor breathe easier will give you some RPM, speed, and holeshot, but 3mph?

    Let me correct myself! this also included a free flow system as well,,,i think it all started when someone tried gutting out there stock waterbox and gained 3 mph,,thats where tony ducas got involved. someone contacted him and asked him about it.he told them he could get the same results from one of his boxes,,i believe he is in the process of building them.
    if you can gain 3 mph with a FF and unrestricted waterbox it want suprise me. at this point im not suprised at anything with this 1.8 motor. a few people are running near 90 mph with just bolt ons for gosh sakes! as more and more people expierment with these new ski`s we will probably see gains that seem unbelievable.there must be some kind of gain from freeing up the exhaust flow if you`ll notice most racers are extrude honing the exhaust system,,gotta be something to it or they would`nt be doing it.a top engine builder told me one time that a combustion engine is nothing more than a big air pump!!! and the more air you can pump through it the more power you produce.makes since to me.
