It says 345 FWHP (Flywheel HP) so that's generally obtained by calculation based on the measured (at the wheels) horsepower. Usually assumed to be 15% as far as I know. So that jives with the numbers shown.

Probably to be taken with a grain of salt, like all dyno numbers. Not to say that's not a healthy motor, but 107hp/litre through SSI's and a muffler is a bit optimistic, especially given the RPM's at peak are pretty low.
