I highly doubt the Linux kernel is the biggest project.

IIRC WebKit has more objects, more files, etc. Its repository's compressed form is >4G.

I know of at least some proprietary repositories with 96G in them. Not much history, but a lot of binary blobs around 128M each doesn't compress well. And bup wasn't used so we didn't get very good compression over the files.
