    Needless to say I got the DVD.

    Here is a rendering. I am coloring some of the parts to enhance the
    pictures :)

    I'll take my computer to Sun N Fun and work on it there.

    Hi Paul, so what do you think can we pull it off?  It is going to be a
    very tight squeeze but I think we can.  My motor mounts are even a
    little wider than a stock Long EZ by about 3 inches.  Anyway, if I can
    pull it off it should be one fast rocket.  Thanks again for your help
    and have fun in the sun!

    No Problem Mike. It will fit.

    Here is some old and some new ideas.

    Hey Paul, did you send something?  I never received it if you did. Also,
    What fuel pressure does the injectors need to work?  For some reason I
    was thinking 90 psi but now I'm looking at fuel selector valves and most
    are rated around 65 psi.

    Thanks

    Mike C

    Not so far.
    50 to 60 psi is normal.

    I got a chance to take a look and the easiest thing is to make a new
    1/2" plate with the starter on the bottom and the right rubber bushing
    holder raised about six inches. The tubes will then clear the turbo
    exhaust manifold.

    If you can't do that I can do it for you as I have a table saw with
    carbide blade.

    Paul Lamar

    Here is how I would do it Mike. No need for a new plate. Just tig weld
    some material on here and there on the existing plate. The inter-cooler
    is shown on top.

    Hi Paul, one more question, I was looking at the picture and it looks
    like if I moved the prop flange out another inch we might be able to
    lower the turbo inlet air tube in front of the engine and rotate the
    turbo compressor to bring it out of the slip stream. What do you think?


    Mike C

    That is a good possibility. I am at the Orlando airport so I will take a
    look at that when I get home.

    In the mean time see if you can find a 2nd gen Turbo II inter-cooler.

    Paul Lamar

    Good Morning Paul, I grabbed my intercooler last night and measured it
    and it is very close to the on in the model.  It was 13.2" long, 11.5"
    wide and 3" thick.  Do you think that will work?  I will need to move
    the ports on it to the sides but I think it will work fine. I was
    thinking about integrating the slide throttle into the outlet side of
    the intercooler and having the injectors between the slide throttle and
    the intake p-port.  Would that work?

    Mike C

    Sounds about right. Got any pictures.

    I was more careful about the lofting this time. It is worse than it looked at
    first. That turbo is too high to fit in the strake with out a bump or two :)
    This also illustrates why we have to pull in the rubber motor mount
    brackets.

    If you moved the turbo down and put the bump on the bottom
    you would probably need a turbo oil scavenge pump.
    It is imperative that the turbo oil drain be above the oil pan level.

Could the turbo be moved to a location under the PSRU? I realize that CG would be affected some, but it may be a lot simpler than
what is being discussed. A bulge in the front of the cowl may not be a big issue. The exhaust could poke out the front side like a turbine.

Dale Davies

Yes It could be but the 2.5 inch air plumbing and inter cooler could be a problem.

Here is the latest with the turbo 2.63 inches below the bottom of the spar.
Has advantages for exhaust and air intake.
