More RS6 Additions

More RS6 Additions

The RS6 has a fever, and the only prescription is more cowbell an overhaul of the fuel system.

Okay, so the RS6 doesn’t really have a fever, we just felt like making a well-timed cowbell/Christopher Walken joke. But its fuel system is still getting a bit of an overhaul, along with a few other miscellaneous bits, as well.

AJ and Tom have designed and constructed replacement oil and transmission coolers. They’re looking at a relatively large increase over stock capacity, much like our C63 AMG oil cooler. Here’s some shots of their progress on these coolers, followed by a shot of one of the stock RS6 coolers:

Next, as part of the fuel system overhaul, we designed and constructed a fuel surge tank to be mated to two fuel pumps capable of somewhere near 1,500 horsepower (a number that should keep us sleeping well at night, since the RS6 is nowhere near the limit on those pumps). If you don’t know, a surge tank stores fuel to be delivered to the engine in the event that the fuel tank itself is running low (which can occasionally provide iffy gas flow in high stress conditions like hard cornering). The second picture in this group is the future location of the surge tank and pumps, along with the new lines we’ve been running:

Underneath the hood, we’ve also installed a new fuel pressure regulator and new stainless steel hoses for the FMU-fabricated catch can (which we’ve had in the RS6 for a while:

Overall, things are still shaping up to look beastly with this German powerhouse. We’re waiting to receive some parts so we can finish up the coolers and everything else, so we’ll keep you posted as soon as things are happening!
