So, the most recent LeMons was the weekend before Thanksgiving. Finally got around to compiling all the pictures and writing the whole thing up.
As a reminder, our theme was The UberBird. Basically a German spoof on the old Roadrunner Superbird that Richard Petty raced in NASCAR in '69 and '70. Thus: 2 feet of nosecone and 4 feet of wing was attached. The paintjob is Petty Blue house paint, applied with a roller (took 2 hours to do the whole car).
Mechanically speaking, we're rocking an early (e-12 based) 633 with a 3 speed auto. The engine's stock, breathing through a glasspack and not much else.
How'd we do? Rather than re-write it all, I'll point you over to my other (other, other) hobby:

The net result: it drives way better now, to the point where we realize we need better tires.
We're still feeling the effects of a neglected 27 year old car in stuff like the tranny mount and ATF lines being totally crapped out.
Going forward, we're still gonna keep the automatic for now. o_0? Because it's not the AT that's holding us back, it's breakage (and mediocre driving). If I swapped in a MT, there'd be a million little things that could get missed that could kill us on-track. Not to mention, I see a *ton* of blown clutches and blown MTs from missed shifts.
Besides, the very 3-speed-auto sound of our car (with no exhaust) has become a bit of a trademark. :D
Given that the tranny mount was all effed up, it's not surprising we're eating guibos...but on the flipside I still don't like them. I know guibos can handle a bunch of torque (and we're not making that much power anyway). My problem's with how sensitive they are to misalignment. This is a crappy car that's getting banged up. There's a good chance things aren't going to be lined up *just right*.
I'm very seriously considering getting a u-jointed 1-piece driveshaft in there like, you know, the vast majority of RWD cars on earth.
I know there's another thread with some guy whos e24 doesn't have a guibo. (LINK (http://forums.bimmerforums.com/forum/showthread.php?t=1357485)) Can I swap in the tranny output from a CV shafted AT onto our our ZF 3-speed? I'm betting the spline count's the same.
One thing we're looking in to is dropping the rearend down some. At the end of the main straight, we were doing low 90s in 3rd at about 4500rpm. If that's as fast as we're ever gonna go, then we should be at or near redline, meaning we could easily go 20-20% lower in gearing...3.73:1 or 4.10:1.
...of course, that's only if we can get a 4.10 (hopefully LSD) side-loader for super cheap. (or "cheap" ;) ).
The other thing I'll be on the lookout for are e23 springs. Those cars use nearly identical suspension to the e12, and I'm willing to bet they've got stiffer springs for all of that weight.
Anyway, thanks for all the help from the board. It's because of you guys that we were able to take a near-junk 633 and turn it into something pretty entertaining.

BTW, that's a Buick V6 powered TR-7. The teams we found ourselves battling with the most were a late 60s full-size mopar, a Ford Ranger and a mid 80s Chevy Wagon. We're faster than the really awful cars, but nowhere near as fast as the really fast cars.
