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.
