According to Bradley Aerospace the engine included with the kit
they have up for auction on eBay is a 1600 cc VW aeroconversion
made by metric A/P.

...
After some of the engines I've seen built by so called "experts"
I'd really suggest contacting Great Plains and build your own.


It's not hard to do if you follow the instructions and keep everything
clean.


And you KNOW what's in it.

...-- $6200 total?


Do you folks think their horsepower estimate (75 HP) is reasonable?
Do you think they would have better cooling inside of a NACAR
cowl than does a typical flat-four installation?


Compare that to a Great Plains 1600 cc V...


Total
$3900


Or for a 2800 cc '80 HP' Total ~
$5800


So it looks like maybe they can be cost competitive with
the bigger displacement VWs.


Meanwhile, does the term "aircraft A/P" mean anything to
anyone here? As in a person who makes airplane engines?

Hi Again, Fred,

Yeah, their horsepower estimates might be for real.
Depends on how much fin area is aaliable to remove the heat of combistion.

... Sure, they may make more power tha that, but
with stock heads, once the head is heat saturated anything over
about 40 HP will lead to a serious overheating condition.


Yes, I've read veedubber's essays on VW aeroconversions.
The HCI radial has five cylinders, so it has more cooling
area and the radial spacing would also improve cooling I
think.

However, a more careful examination of the HCI website
and an email from the proprietor confirms that the kits
only include those parts that require close tolerances or
are machined from specialized castings. The builder
would need to make many more (albeit simpler) parts
from billet. Given the cost of custom work, I don't
doubt that one gets good parts for a fair price, but
you'll need more than a socket set to build one
of their engines from their kits--rats!

Meanwhile, Mr Huggins has sent me a longish (at least
compared to the previous correspondence) email explaining
among other things, that the 1600 cc aeroconversions he
is including with the kits advertised on eBay are made
for him by "an aircraft A/P that's in the VW business"
who does not sell to the public.

A phone call to Metric Auto Parts in Chico, CA confirms
that they are this mysterious supplier. I guess "A/P" means
"Auto Parts". Of course no one would confuse that with
"A&P" (airframe and power plant) so there was no need
for Mr Huggins to spell it out...

Scuttlebutt has it that he has sold a few kits and may
even have shipped or be near to shipping some at this
time. He is also rumored to be moving his operation from
his old location to a building near the airport.
