    Thanks for the support guys!

    Brad thanks again bro on your advice on the rerig!


    Here is the completed assembly.

    it measures 67 inches long and 35 inches high.

    The assembled weight is approx. 600lbs
    This engine will produce 1480SHP

    The "FOD" screen (foreign object Damage).. (Bras, G-Strings, Seaguls) is visible.
    The copper pipe coming out of the top of the intake is the
    Methanol injection which doubles as a compressor wash.

    When they first arrived I was amazed on how small they were.

    Very similar concept. As the daisy wheel (N2) spins, it is connected to a shaft on a bearing. The N1 GP nozzle forces air onto the PT wheel and in turn spins the wheel and the shaft.

    The shaft is splined to accept an input shaft and thus power is coupled.

    This is the same for the hot shaft and the cold shaft engines. Therefore, there is no mechanical connection and you can stop the N2 from spinning provided you have sufficent means such as a caliper and rotor to do so.

    hea for us dumbies. can you explain the connection between the two shafts in the motor. how does the power get bcak out if there is no mechical connection ?? is ther some kind of lock up converter?

    There is no mechanical connection between the two systems. N1, N2.
    It is a "free Turbine"

    N1 is the gas producer which means it produces Hot gas (Combustion)
    that is directed and focused onto the Turbine Wheel (N2).
    At low Rpm the Force is not significant enough so that the design
    allows the N2 to be stopped without issue.

    Picture a compressor airgun. EX. like a blow off nozzle that a garage uses
    to blow debris off something.

    If you put a free spinning Wheel in a vice. EX. Like a Computer fan.
    If you apply the airgun to the fan the force of the air against the blades
    will cause it to move. It will Move pretty fast also.

    This is a basic analogy.

    Here is another EX.
    A Turbine wheel put in niagra falls would cause the wheel to spin.
    The water being N1 (gas producer)
    N2 being the Turbine.

    Hope this helps SkaterBrother

    Here i go off to Geek ville!


    The Basic gas turbine is comprised of three components.
    Compressor, Combuster, and Turbine.

    The basic gas turbine:
    The Compressor is driven by the turbine through an interconnecting shaft.
    Compressed air flows through combuster where it is mixed with with injected fuel. Ignited. These hot gases flow through the Turbine. The turbine extracts
    energy through this. This is your Gas producer type Turbine.


    The Turboshaft gas Turbine:
    In a turboshaft engine the turbine provides power in excess of that required to drive the compressor. The excess power is apllied as driving torque available at an output shaft The power to drive the output shaft can be extracted eithier from the same turbine that drives the compressor or from a separate free wheeling turbine . This is free wheeling no mechanical connection.



    The piston Gas motor makes power on the powerstroke of the piston.

    The Turbine makes power continuously.

    The Turbines found in our example here are a turboshaft engine.
    These have a output shaft.
    The Turbines found in the airplane you take to vegas are Turbofans.
    These produce thrust! rated in Pounds.

    Thats all the Spewing of BS i got for now.

    so its like having two fans the first one making the power, (ie wind), and the second fan has the shaft connection and when the wind isn't stronger enough you can stop the fan blades.

    Yes in simple terms.


    at 40% rpm of N1. The N2 is only making 22hp.

    Now there is a thermal limit to how long you can keep it stopped.
    Remember all those hot gases of N1 are now slamming against the
    staytianary n2 blades.

    1 minute would be close to the limit.

    Turbines make 90% of there power uptop in RPM.

    There rpms are measured in percent.
    n1 max 26,500 rpm 105%
    N2max 22,500 rpm 102% this is reduced via planetary output gears
    located in the turbine to 6600rpm.

    I thought the correct words are suck -blow -bang. Is that in the coreect order.
    That was Military talk.

    No, thank you...for showing so many people that a turbine installation is much simpler than we all imagined (me included til I did one), and can be completed by someone with a little experience, time, and a budget.

    Look's like installation time !
    The Turbines echo off the surrounding buildings so much better when it's below 20 deg. out.
    The air boxes came out great !

    YES The true secret behind the scenes


    You hit it right on...........
    Turbines may not be for everyone, However With a little bit of mechanical
    ability and the drive it can be accomplished.

    Hey what the heck I,m a used car salesman
    If I can do it anyone can.

    Seriously I could supply measurements and any info that would aid in
    a do it yourselfer.

    The bell housings and brakes are already available over the counter.
    The SCS gearboxes are from what else SCS.
    Really the only custom would be exhaust and intake.
    A Sheetmetal guy can do this.

    There are several ways to install them. This way may not be the best
    However, The boat runs, drives and shifts awsome.
    One of the biggest things is they dont stall around the docks Second
    to only the unbeleavable acceleration.

    Whaz up Kenny?

    Beleave it was over a year ago when we dropped them in.

    If memory serves me we got 6 inches of snow that night.


    Dont be a stranger I could use a hand when we go for round two.

    No-No-1, any ?'s RE: turbines and the great possbilities of their applications come on guys & galls shout out now ! has any 1 ever analyized a v-drive set up with a turbine ? --- ? or exhaust/engine cooling etc. everyone sleeping ? Artie-help us out dude. -

    Don't know what you are asking as you as it is difficult to follow your writing, but why would anyone need a V drive?

    The engine can plug into the drive. Your asking why are the engines mounted rearward and the exhaust forward. Answer: drive line length. The engine is basically 48" long, the drive line would have to go this length plus. Also the engine would have to be mounted higher upward (when dealing with a Merc #6 that is). Then there is the cooling and such of the V drive which technically is a Parallel offset box. An actual V drive would put the engine at the typical 10 degree angle that is in the V drives.

    Did I mention cost?
