Almost right. The number is 5252. So for instance if you make 120 lb/ft of torque at 4000 rpm:
120 x 4000 = 480000 / 5252 = ~91 horsepower. Not too impressive...
However lets say you make 120 lb/ft of torque at 7000 rpm..
120 x 7000 = 840000 / 5252 = ~159 horsepower. Much better!
So the trick is to make torque at high rpm. BTW this isn't very easy unless you have variable valve timing like the VTEC system because one camshaft can't work very well all the way up to 7000+ rpm...
