I have an 04 WRX with H&S Backbox. Just fitted a boost gauge and getting a steady 0.85 bar boost in every gear. Is this correct for the car?

I am going to fit a dawes device, what would be the max sensible boost to run without damaging the engine?

Cheers

 

Mine's peaking at 1.45Bar after a remap...

 

Sounds about right, standard is about 0.9bar IIRC (anyone confirm?).

Remapped with standard turbo, etc you should be looking at 1.2 to 1.25 bar. Mine peaks at 1.33bar.

 

That's really interesting - what power is your car making? Mine is 'only' making 271bhp. Reckon the extra boost is down to an aftermarket intercooler...??

 

Yeah standard should be approx 0.9 bar.....I get between 0.9 to 1 when on full boost...


I get mine mapped on Saturday, so will let you know what i`m running after then...

 

At what pressure does the ECU cut the fuel? Is it 16.5 PSI?
