Default Re: Another bogus hp rating.

It's interesting how people throw "torque" around.

HP=Torque x RPM / 5252

So HP is nothing other than a mathematical derivative of torque.

It's been a long time since I've seen a normally aspirated car in Stock Eliminator (especially when you get above L,M, or N) run less than about 5500 RPM stall, or leave at less than 5500 if it is a stick car.

So, 5500 RPM is above the point at which torque is a higher number than HP, as torque and HP will ALWAYS be equal at 5252 RPM, and torque will ALWAYS be greater than HP below 5252 RPM. That also means HP will ALWAYS be greater than torque above 5252 RPM.

In this modern era of efficient high stall converters that yield in excess of 2.0:1 torque multiplication at their flash stall speed, and trick clutches, when someone tells you that it is necessary to have "torque" when "moving a heavy Stock Eliminator car", remember that in order to make HP, you must have torque to begin with, since torque is the actual force, and HP is merely a mathematical derivative of the force called torque.

Two engines that have "X" HP at 6000 RPM have the same exact amount of torque at 6000 RPM, regardless of how many cubic inches they displace, what their bore/stroke ratio is, or what their rod/stroke ratio is.
