GM\/CHEVROLET HORSEPOWER AND TORQUE CURVES<\/h1>\n

If you study the performance curves below you will see two major benefits of GearSplitting. As an example we’ll use the TH400 or 4L80E trans chart with a Vortec 7.4 (454). Gears are multipliers of torque so at 3,000 rpm in 2nd-over the torque multiplier is 4.73 where without the GEAR VENDORS<\/b> you would get into 2500rpm in 3rd-direct at 4.10. The difference in engine torque is only 10lbs ft. but the difference in the multiplier 4.73 vs 4.10. That’s over 18% more working torque.<\/p>\n

At this same moment horsepower at 3,000rpm is 260 instead of 210 @ 2500 which is over 23% more horsepower with all the reliability of your stock powerplant. To figure the drop in rpm or torque multiplier from on gear to the next calculate as follows: Final Drive Ratio of the gear you are shifting to, divided by the gear you are shifting from, minus 1, times 100. The difference from 1st-over to 2nd is even more dramatic. This is why if you are towing or loaded heavily, the best way to reliably improve performance is with the GEAR VENDORS UNDER\/OVERDRIVE™<\/b>.It’s the same reason the big 18 wheelers have 2 and 3 speed auxiliaries for 10 to 15 or more gears.<\/p>\n
