Boost on EVO
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.
