.9 bar plus atmosphere (1.9) is 6% more than .8 bar (1.8).

Thus up to a max of 6% more hp it that is the only change.

However it is often less if efficiencies are falling off somewhere like going out of your turbos efficiency range or if the intercooler can not accommodate the increased heat and air flow.

Thus, if it is a stock 260hp car that is up to 16hp. If a 400hp car up to about 24hp.
