The graph is very linear and look at the torque at 3000 rpm! That should spin some wheels. Or break a gearbox... Any way I would really like to see a v-cam equipped rb28 with EFR8374 t4 0.92ar. It spools a bit faster than GT35 which spools a bit faster than T04z.
I found this on hks website under v-cam step pro. It says rb28, v-cam step pro and t04z so this is probably how the BNR34 driving performer dyno could look like.
