I was just reading an article about converting a Type 1 Beetle engine to a Type 4 setup, and they cite the difference in weight to be about 26 pounds, assuming everything else is equal. I think GPASC calls the Type 1 160 pounds, but that doesn't include the exhaust system (not sure about the hub) so that would still be under 200 pounds. By contrast, I weighed my Corvair with "everything but electrons in the wires and fuel in the lines", including exhaust, hub, plug wires, plenums, everything, and it was right at 245 pounds. Some folks call the Corvair a 220 pound engine, but it all depends on what you count, and what the basic engine includes (starter, hub, exhaust, hub, alternator), all of which was included in my original Corvair weight estimate.
See http://www.superbeetles.com/Tech_talk/jan2.htm for some interesting stuff on Type 4s, and cooling in general for VW engines. There's a lot out there to read about Type 1's and 4's both...enough to keep your average person busy for a year, I'll bet. I'm going to give that up for the day though, and do my best to clean off my workbench, since it's too icy to even walk outside... Mark Langford ML at N56ML.com http://www.n56ml.com
