[QUOTE="Dirty Dog, post: 453764, member: 24042"] This is true. Kind of. Sort of. But not really. Torque is considered the more important number, but the two are inextricably linked. Because torque is measured, and HP is nothing but a mathematical concept derived from the measured torque. HP is Torque X RPM/5252. Which is why the two lines on a dyno chart always meet at 5252 RPM. And why higher RPM equals more power (within the mechanical limitations of the valvetrain and rotating assembly). Increase torque, and you increase HP. Getting out of your own way is indirectly related to gearing. Gearing is a torque multiplier, but the baseline torque is still the determining factor. There is no combination of gearing that will allow the 237lb/ft produced by the JK 3.8 to keep up with the 711lb/ft produced by my Vette, even if I leave the Vette in 4th gear and eliminate the torque multiplying effect of the gears. Gearing is a great thing. But it's no substitute for actual power. [/QUOTE]
