Around 400 whp you run out of MAF. Stock injector is a 444cc that runs out at about 440 hp at the motor safely. Stock turbos lose ceramic exhaust wheels.David_NISMO wrote:My favorite part about the rb26 is that the entire motor will support over 425RWHP before any modifications need to be made. This includes, injectors, mafs, turbos, and ofcourse all internals.it also has internal throttle bodies which create better engine responseStock bottom end has been taken to over 1000hp.
I have done 654 rwhp on an internally stock 26, and I have ran 137 mph with an all stock internally 26.
The 26 has individual throttle bodies.
As far as stock and 1000hp....like a ticking time bomb. 500 rwhp it will last ok. 600 whp its iffy...
