REFLECTOR: Turbo leaking

Mon Oct 21 13:47:42 CDT 2013

I installed a restrictor in my turbo supply line, the manufacturer said that
the seals would tend to leak and then blow out if it was just supplied with
an unrestricted line. I can't remember the diameter of the orifice, but it
was probably about 0.10 or so.

No turbo here, don't need it to get a calm 340 HP. Didn't want the headache,
heat, or problems up front. 

Later? We'll talk.

You have a turbo, right?
If it's new, it's going to leak.  Mine leaks pretty bad at the moment, and I
think I'll need to add a restriction in the oil line so that the scavenge
pump can keep up.  I'll just need to be really careful about not restricting
too much.

The engines I build don't leak :)  

But they are not ancient technology either!

Seriously.  Makes me sick.

Seriously again.  How does one do this?  If you fly, it's going to get oil
mist everywhere.  I just don't see how this is possible.

<mime-attachment.jpg><mime-attachment.jpg>Here are some photos of my NACA
system.  Very little work to do on the fuselage.  It worked well in Tucson.
Also, the engine is more open.

I tend to live the, "If it ain't broke, don't fix it" and the "KISS" method
of life. I wonder if there will be rain water in the engine compartment? It
does look cool though. I am with you on the Fiberglass work too. I did not
build mine either. Maybe I am skeptical about changing and cutting into my
fuselage and firewall of a perfectly flying machine.  But I don't think you
will see much of a speed improvement either. Just my thoughts.
If you do the change, please keep us informed on progress and challenges,
etc..
Good luck,
Jeff

I have armpit scoops, and attached the scoops to the fuselage, instead of
the cowl.  Removing the bottom cowl is not a problem if one does it that
way.

I am having cooling problems though, and if I can't solve them, overhead
cooling is one of the options still on the table for me.

Easier to work on though. I always had issues taking off the bottom cowling
before the NACA upgrade.

I agree with Scott B. I have done one NACA conversion, its not a one day 
or one week job. There is also a plenum to build and fit, exterior 
paint, the inevitable cooling issues to solve.

If you don't have a heat problem, don't fix what aint broke.

have done several roof top NACA scoop conversions that require several days
of labor and re-upholstery operations. It's not worth the effort if cooling
is not an issue.

but am considering changing to the NACAs I did not build the aircraft so am
challenged by glass work. but can find good help on this. Does anyone have
experience on this type of project? Drag reduction? other advantages? I have
flown 450 ? hours and have no cooling issues except have to watch oil on
long hot climbs. Is a kit available? Any input would be appreciated.
