I think that the -6 factory accel linkage is overly complicated. From the pedal, it goes through a rod, and arm, a cable, back to a bellcrank, up another rod, to another bellcrank, another rod, the crossbar, one more rod on either side and THEN to the carb arms. I can't understand why Porsche did it this way unless it was just so that it would resemble the 911 setup. I'm not one who questions everything that Porsche ever created, I'm not a wheel re-inventer, but I'm not a purist either.
It seems to me that every extra link and every extra rod adds a bit of friction and another potential failure point. I remember seeing Drew365 get sent home from Buttonwillow for the weekend on Saturday morning because the bellcrank shaft that screws into the side of the intermediate plate broke off. It seems to me that a cable gracefully arced around the side/back of the engine to a bracket to hold the sheath and a ball socket to clip on to the crossbar ball would be a lot cheaper, simpler, smoother, and more reliable.
In the interest of not re-re-inventing the wheel, I'd love to see what you guys have come up with.
