Also not all dynos are created equal. I can't believe Woody had a 36% loss, not possible with a manual they are more efficient than automatics. I think you forget that people where getting shut down earlier because of improper dyno runs.
Yes, you can ignore my run for any meaningful comparison. It was an incomplete run to 5,000 rpm and done in 4th gear which is not direct (should be done in 5th) so there will be more losses through layshaft etc.
