well, if you mean you want to gear it up(speed increase(torque reducer)) the biggest one I've ever seen is a 5:1. I don't think you can possibly get them higher than that.
I am not very familiar with the above formula's but I know the base unit for horsepower(definition) is its the ability to move 500 lbs one foot in one second.
Although. . .the above definition sounds legitimate.
I think the mishapy may have come in at the computing it for the output. The formula seems competent to derive horsepower from the engine but it seems like you just didn't multiply the output of the gear pulley by 30,000 instead of just 1,000.
i.e. you said it sees 1/30th of the power the engine produces and by that I think you mean torque. True per rpm it sees 1/30th of the torque. . .but it also sees 30x more RPMs. in using a gear assembly to change the speed/torque you effectively multiply by one because if your formulae holds you aren't changing the numerator(its torque times rpm) so if you decrease one in the pulleys you automatically increase the other. If its an ideal pulley. realistically most of it gets through but you lose some to friction and gear grinding.
