I don't think anyone knows either BTU rating. The Omnifuel + OmniDawg cap is a custom modification. I've talked to several people whose opinion I respect who are fellow stove collectors. The consensus is that the OmniDawg does increase the output of the Omnifuel, but by how much is anyone's guess.

Probably MSR has a BTU rating for the Whisperlite, but I'm not privy to that information.

If I had to guess, I'd guess that a WLU puts out about 11,000 BTU, and that an Omnifuel with an OmniDawg puts out about 12,000 BTU. That is just a (somewhat) educated guess.
