Turbo Lance II opinions

Hello,

I'm looking to talk with someone who's owned a Turbo Lance for their
opinions on ownership and maintenance.

Thanks.

My first airplane was a 79 Turbo Lance. I bought it for the roomy cabin for
my dogs, reasonably fast cruise and fairly good altitude capibility. It was
a releative bargin compared to other six place, 170+kt, turbo airplanes. I
found it to be a good airplane for me and it met my expectations. Mine had
most of the availible speed mods and an intercooler which I recommend. I
only had if for about 16 months so I can't tell you what the long term cost
of ownership would be.

With all that being said, why did you sell it so fast?

I needed an airplane that could cross the Sierra in virtually any weather so
I needed deice and radar. I was making flights where I had to be at the
destination.

I must admit that I'm not very smart on the turbo options. This would be my
first turbo engine.

I've seen some Lance's advertised with Turbo and then there are some that
specifically advertise Turbo with Intercooler. Are these two seperate
options available or are they one in the same? The Lance I'm looking at
just says Turbo in the ad and doesn't mention any intercooler.

Thanks.

The intercooler is a aftermarket STC'd modification. Without it, the
airplane will not be able to maintain high power settings above about
16,000' without overheating.

An intercooler is a radiator that cools a gas (air) instead of a liquid.
When air is compressed (what a turbocharger does) it heats up. When a
gas is heated it wants to expand (return to an uncompressed state), so
you place an intercooler (or two) inline following the turbocharger and
before the engine air intake, to cool the heated, compressed air before
it enters the engine, providing cooler, more dense air to the engine.
Cooler dense air can absorb more heat than hotter dense air and provide
greater expansion and therefore more power.

Or it can provide the same power with all the temperatures being lower
(inlet, combustion, EGT, TIT).

Technically, an intercooler is a "radiator" placed between a
exhaust-driven turbine compressor and a mechanically-driven turbine
compressor (a la B-17). Your description of an aftercooler is spot-on.

You may not be familiar with the Turbo Lance/'Toga "intercooler"
installation. It is a relatively inefficient aftercooler installation
that has other very important benefits.

It changes the existing lower cowl design from a single common air
inlet which is shared between updraft cylinder cooling, induction air
supply, and oil cooling air cupply. The new lower cowl has separate
inlets for updraft cylinder cooling, induction air, and oil cooling,
as well as the aftercooler inlet.

Unfortunately, the outlet of the aftercooler heat exchanger is
exhausted into the pressure area for the updraft cylinder cooling.

The installation will drop operating CHT by approximately 40-60
degrees F, and operating oil temp by 20-40 degrees. Considering that
CHT can run 450 F and oil temp 220+F this is a very good thing.

I honestly cannot recall the typical induction air temp drop, but the
overall package works quite well. IMHO this is as much a result of
improved engine/oil cooling air flow as actual induction air cooling.

Personally, I would not consider operating a Turbo 'Toga/Lance without
this modification.
