Has anybody here heard of VW aeroconversions by a company

I haven't been able to find them on the Web.

Never heard of him...

How big is this company?

I have yet to find evidence that they exist. Consequently,
speculation as to their size would be unwarranted.

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.

I dunno, Fred.

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.


I've also been thinking that one could design a radial engine
that uses off-the-shelf VW cylinders, pistons and maybe
even scat heads. As with most such ideas, someone else
has already tried it:

http://www.hciaviation.com/pricing.shtml#standard

$ 5200

A set of pistons, wrist pins and cylinders runs anywhere from
a little over $100.00 to maybe $500 unless you get really
wild. Add that to the ignition components, bearings,
belts etc and I would guess you'd maybe have another $1000
in parts -- $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 VW long block -- $1800
Plus an accessory package, at least -- $1300
Plus their dual ignition accessoriy kit --
$700
Plus filters, bolts, (belts?) etc maybe ~
$100

_________

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.

BTW, that one minor detail is the reason ALL VW engines are really
only 40 ho engies. 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.


YMMV, but not much...
