Highest Boost on RB25 running SAFC

[DezertEagle]

A rebuilt and hi-flow turbo just became availible to me at a very good price.

I want to run ~16psi (I understand 18psi is approx highest on standard internals)

Will just SAFC be good for 16psi? Or need PowerFC?

I hafe:

- Turbo back zorst and hi flo cat

- FMIC

- upgraded clutch

it will work fine :headspin:

aslong as there isnt any timing issues

its not about how much boost, its about the amount of airflow :type:

i wouldnt run this airflow with only the safc, youll benefit much more with power fc

i wouldnt surprised if you just get boost cut all the time from the stock ecu, way too much airflow @ 16psi

I have a 94 gtst and havent had any problems at over 1 bar, the highest ive ever run it was 1.2 bar, after pulling my turbo off it was apparent that it had been rebuilt/reconditioned recently so its not quite as dangerous as doing with the standard turbo

my dyno power curve at 0.9bar is dead straight with constant power gain,

180.3 rwkw with the afr's in the very low 10's

i dont think the standard ecu is as weak as everyone thinks, its probably most of the other systems that stuff/support with it

i think the standard ecu can support 220-230rwkw if everything else is done properly + piggybacks
