As an Engineer I can tell you the formulae is rather complex, and probably more than the average person wants to tackle. However, the short answer is to find a similar-sized gas-powered blower and look at what hp the drive engine is, then just ask the hydraulic supplier for an engine that puts out a similar power. As a word of caution though, hyd. motors become less efficient at higher speeds, which is what you want for a blower, you need to either, run more power and gear the blower to run faster than the motor, or try another power supply, such as belt driven from the engine. Best of luck. ....
