I thought they were a 400 hp turbo absolutely flat out
Not really no. A gt25 hybrid can get 380bhp. Sabre have been getting 430bhp from gt28's for years. A few cars have made similar figs on this roller to others. The std cars on the day were making std figures
Heres sabres league. 6 x gt28's over 400 and 1 making 389bhp at 19 psi. The boost beside the figs is peak and hold so some are making the figs at 20-21 psi. So is my 392 at 23psi isnt that optimistic i dont think
Heres a few gt28 graphs so can see there running 23psi(1.6bar)
