i was searching through google and there are converters for horsepower to kilowatts and bar to psi.

however i was wondering for every 0.1 bar increase in boost pressure, roughly what does this equate to in engine power increase in kilowatts?

i know that this depends on the type of wrx and the type of mods done on the car, but for this case, my car is a 1998 wrx, with modified full exhaust and air filter.

ussually talkin on a stock car its bout 10hp

It's complex.

Not so much increase in boost but increase in air volume. (correct me if I'm wrong)

I'd say you'd be right Pete, most important factors would be volume & density. Interesting tho that someone worked out a hp approximate for a stock car. I guess an advantage of having one of the most popularly modded cars around.
