wtf why so high the early evo and vr4s only did 8 or so

[80ove]

An EVO VIII is 1.3Bar (18Lbs) Standard, with spikes up to about 22Lbs., and after a change to Ralliart ECU regularly run 1.4Bar (20.3Lbs) daily, have run 1.5Bar (21.75Lbs)on the street, and have had Boost Cut at 1.7Bar (24.65Lbs) after fitting Ralliart ECU.
Later model EVO's have no problems running these pressures, but the car is more livable on the street running around 20Lbs of boost, monitored by an EBC.

so whats the stock boost model by model?

Ive got an Evo 8 and it was 17psi Std.....

wow old thread.. lol anyways i heard the 9's run about 20psi and drop off gradually to 16psi at redline, also heard that the ralliart ecu lets it keep full boost to redline that would surely make you realise something is different! haha

Holy Crap.
You just bought up a thread from 18yrs AGO!

[Grebs85]

haha well the evo9's were new back then so i guess it wouldnt hurt to let people know how much they usually run in OZ SPEC evo ix's..
