You are right about there generally being something more out there. Examples: straight up manifolds and TBs for same, to avoid the blasted Weber based bends in two of the three. Just more $, or clever use of motorcycle TBs and a way to make tapered tubes, TIG aluminum, etc etc. Several discussions of that. If I didn't have a complete TWM/TEC3 as part of the price of a solid running motor purchase, I'd be futzing around. Probably for years and years.
Just splurged on some Buckley Racing exhausts.
Of course, I had to lighten the rear support.
If I can figure out how best to lighten square tubing with minimal reduction in its resistance to bending (compression and tension don't seem too important here), I'll be back at the drill press, saving grams and nanoseconds on laptimes.
One of the great East Coast engine builders is running a vacuum in his 911 motors, as Porsche does in its race motors these days.
But, alas, I have pretty much abandoned the idea of boring these TWM 40s. Switching to up top injectors calls for a lot of careful thought and work, coming up with a rather different air filter (though that would be a use for the K&N Watershields I retired in favor of ITGs). To say nothing of some more $ and time.
If I can work a swap (working on a 3 way deal), I just might be able to run EFI at the Miller PCA race in September.

Oh - speaking of lightening our cars, there is a thread about that out there on one of the Pelican fora. I'm even subscribed, but for the life of me I can't find it to post several more labor intensive savings of very little weight. Anyone know it? 911 or Autox/Racing, most likely.
