    the engin started life as a 3.3ltr ficht injection engine!

    bolted a Etec front half to it

    used old style large rods
    custom pistons
    and motec injection-ignition on it with a MAD EFI slide front

    the engine pulls arround the 8,000rpm mark but could probly get some more out of it!

    so this weekend we are going to try and strech her out a bit at the one up and we want to break 100mph with a skier on the back!

    Where is the bridge to Bridge race this weekend


    AS a side note Adam Whitfield aka Bullet 1650 has just hit GPS 98mph with an STV & a stock Evinrude 250HO including STOCK L2 gearcase in Sydney, Australia. Has a modified same brand prop on the way which will hopefully see him to 100mph+. These new L2 gearcases & the 250HO's are awesome. Again I'm saying ALL STOCK, no mods, no nosecones. Factory EMM Rev limited to 6300rpm.

    Ken, I think Adam lives in Sydney, his brother will probably run in the powerboat race on sunday morning, 1750 bullet with a 2.5 merc on it. I wonder if Adam is racing the STV. That boat should run over a 100mph easy. Brad groves force will do that too propped up. He's hitting mid 80's with two skiers.
    Anthony, have you taken possesion of Darren's boat and motor yet and racing it in Sydney or is he driving it. 100mph 1 up would be cool. Are you buying the hull and injection/ignition/motec less block or are you getting the block too. Did you ever rebuild yours after it popped?

    i run one of those gearboxes on my engine at the moment they are alright but they would be better if someone made a low water pickup kit for it!
