You would have to figure out how to connect the fan. I think the stock
VW fan moves about 1000CFM at 3000rpm and about 1500CFM at 4000rpm (when
I have been told the belt starts slipping). Veeduber I am sure has the
proper numbers.

The numbers,, proper or not, are 1300cfm, according to the VW Factory
Service Manual... or whatever... (black covers w/embossed silver
printing). But I think it's a giant LEAP backwards. Somebody out
there is sand-casting VW crankcases in aluminum. Torture them with
lotsnlotsa money and get them to shuffle things around a bit, allowing
a BORE of about 4.625" and a stroke of 88mm, then cast a LONG #1 main
bearing and throw away the tranny flange... might even get them to
cast a Dyna-Focal mount on the other end... and make some entirely NEW
1-cylinder per head headz, and we can stop calling it a VW (although
we'd still be using a lot of VW parts) and start calling it a DIY
Homebuilder Engine... with about 100bhp @ 2700 rpm (or whatever... use
the C-90 cam timing; get someone like Dick (sp?) Schneider to grind us
some wiggle sticks. 40A. coaxial alternator. Itty-bitty geared
starter. Electronic ignition. Holes for two plugs. SIX head-stays.
Juice valves outta the little Chevy. Absolutely NOTHING
certified...although EVERYTHING has done a million miles or more in
other engines. That is to say, there ain't nothing new in such a
design.

Kinda heavy, though... about 181 bare, mostly because of the crank.

Well, those weight and power numbers look mighty close to the numbers that
Continental is just bringing to market and Lycoming is working on. So, if
you feel the need to swing a 70 or 72 inch prop and ALSO prefer a direct
drive engine that can idle on approach, they are still good numbers.

I could very well be a customer in the easily foreseeable future.
