mickR33 is making 265 without cams at 17 psi OP6 rear housing so it still has a bit in it.
Dyno Sheet
Modifications for his car are: Power Fc, FMIC, full exhaust, Nismo reg, Bosch 040, Z32 AFM and using
a turbotech boost controller.
Best results:
279rwkw on vg30 max oversize 19psi
268rwkw rb25 housings with stage 3 max oversize turbine 19 psi
262rwkw rb25 housings with stage 2 turbine 19 psi
249rwkw rb25 housings with stage 1 turbine 18 psi (much smaller major diameter - used when asked to mainly on RB20)
Nic holds the best power rating for RB20 241rwkw stage 2 turbine at 19psi
Results would have varied slightly from DYno to Dyno.
Our Dyno will hopefully be installed at the end of this month then the real in car R&D will begin on the same car for best results.
18psi is the best for psi vs gain
