I have an unnatural interest in the /6

BMW fans are thrilled they returned to the straight six, after several years w/ a V-8. A turbo-charger overcomes the slant's poor-flowing heads, and has gotten one guy into the 10's in 1/4 mile. Seems turbo would be much harder for a small-block, given you need 2 turbos (or complicated plumbing) and much less space.
