Standard RB25 airflow meters won't see 500BHP +!!!

Z32 airflow meters will see 500BHP safely and Q45 airflow meters will handle 600BHP +.

When the car was mapped by Tweenie, it made 535 on those RB25 AFMs, so I would have to disagree with the above. A single RB25 AFM can do 300 on a GTS-t.

£156 aint bad to be fair, id probs go for it, get them tested before throwing the old ones out though.

there definateley ok they are working fine but i know at some point i will want more power so dont want to miss a bargain. 1.55 bar boost and they were over 5.1 volts, im sure ive read on here someone ran 1.7 bar with 2860-5s with rb25 afms on.
