Allan: You really have to admire those Yank Dynos and the DynoJet. Puts the Summernats dyno to shame. The calculate a different HP, also different drive train lose and "correct it" for atmoshereic weather and conditions and the fact they dyno on C16 etc.
Dom's dyno numbers are very humble and it's tuned for street fuel, eg 98 octane.
Infact I suppose if you wanted to get into "comparing dyno numbers" Then look at Seb's 7M Powered Supra, 700rwhp on a Dyno Dynamics.
Just because it has a huge turbo on it it's expected to break some dyno records??
