oh, I know all about adding power to bugs, but I was trying to figure out what sort of trans configuration would be able to mount up to the engine and have it sit in the right spot. a bus tranny would probably fit the bill, but you'd have to get it flipped to run mid engine, not too much of a problem though, it's been done thousands of times.
and yep, VW's twist not just the frame horns, but the entire body. my dad's bug up till we finally hooked the cage into the frame horns would run I think a 1.6 60' time after we tied it in, the 60' time's started to drop, and it was reacting MUCH faster (first time out he redlit REALLY REALLY bad because of how much harder it was able to put traction down)
caster shims haha, yeah, I love those things, but I love camber compensators even more. especially with some KYB Gas adjusts. I had that setup i my 62. we were going to put in dropped spindles, but swapped in an adjustable beam with a set of caster shims. put kyb gas adjusts in and a camber compensators. it had the original hydraulic shocks in before. first time I drove it on the street I shat bricks because of how much roll that thing had in the rear end. after the part swap that car would handle like a gokart. even if it got sideways there was almost no body roll.
imo a superbeetle would be a bad base to use for the swap an older bug is much simpler and lighter imo.
my dad's 66 btw weighed 1800 in stock trim. then we added 100lb by adding in a roll bar, then took out 100lb in tar mat, glass, and extra metal that it didn't need.
put a fiberglass front end, fiberglass doors, and all lexan windows and you can get it down to under 1200 real fast.
the only big problem I can forsee is that when you flip the trans to work midship duty, the bellhousing sits to far forwards for the engine, but you'd have to take a lot of measurements and see where everything would sit.
well...there was that Flat-8 3200cc bug built, with the entire back half of the shell being fiberglass, built by mating 2 1600cc engines together, and running it through a porsche transaxle. I found the site once and should've saved it, because I can't find it anymore. apparently it was one beast of a track car.
