    Default land and sea turbo

    any body out there remember the land and sea turbos that they made for o/bs?
    or ever seen 1 run?
    i went out to scott eines shop the other day
    if anybody remembers him he used to race mod vp in the early 80,s with dave barnett,
    he has land on lake livingston with an air strip,and a full blown aviaton shop and hangers,he builds and repairs airplanes,made his own gas tubine engine from a starter motor for a scaled plane he built
    amazing to see what comes out of his mind

    anyways he used to build his own version of a mod vp boat ,jack plates,props
    we went through his storage container of his old boat stuff

    he had 1 of those turbos,,,that was played with in the mid 80s
    and of course he had to make mods to it,,,,needed more booost,added an intercooler inside the intake box,,it even has an air plunger after the turbo to dump exhaust above the water at high rpms

    thought it was a real cool item and had to bring it home with me
    and you know it will be going on a motor,,,,,,,

    also got some old boat air brakes he made,
    ron will like this,,some homeade props that they machined from stock mat

    was real cool to see the stuff he built back then
    and what he builds now

    if anybody out there ever ran 1
    give some input,,,was told they only made 5 of them

    Neil Holmes from the UK built one around the late 80's. He said it was one of the scariest things he had ever driven and he was really handy in a boat. We looked at building one for UK MOD VP but went for the Land & Sea big bore conversion instead. You could try and track down Gordon Sutherland in the UK who worked with Neil for a while last I heard he was a race official on the UIM F1 circuit. If you ever get it running let me know and I'll send you a new pair of pants.

    Default Turbo Power

    John - I worked for "Smilin Jacks" marina north back in the 1990's. The owner of the buisness played with all sorts of cool 2 stroke bolt ons. One of his projects was the Land and Sea Turbo. He made some changes to his set-up to make the unit more dependable and tuneable. The unit was sitting in the attic of his buiesness when I worked for him collecting dust. He lost interest and went on to other projects but I know he had some very fast times in the Hydrosteam he was running it on. If your serious about doing a project like this I can PM you his ph. #.

    Default cool stuff

    this 1 here is made for the omc crossflow
    i was around scott back then when he worked it

    its main downfall was the crossflow turned up around 7,500
    and the main boost came in around 5,500=6,000
    so with boat around 80 and aired out,,,,it would excell harder and change boats attitude,,,,not a good thing,,,,,

    so he started adding more boost for low rs and wasting it out on uppers
    got more controllable and after the intercooler was added it was crisper

    im a merc person since the early v-6 came out
    and always wanted to get the ex divider for a merc and build my own intake plenium
    i ran unlimited o/b,,,,and ran alky with nitrous,,,so never messed with it
    so it has been shelved for the last 15 yrs

    so i have a bud thats getting it
    hes a long term omc guy
    and he is to put it on and run it
    we just want to see it back in use
    will post photos when it gets on and running
