The lightest and best aftermarket pulley solution for your 3.8 Genesis was specifically designed and is exclusively distributed by Throwdown Performance. This set reduces the most rotational mass from over 7.5 lbs to under 1.5 lbs, freeing up an estimated 12-16 hp increase at peak, and remaining perfectly balanced.
Standard Belt Layout (Underdrive)
Our pulley sets provide most of the power gains through weight loss (80-85%). The remaining part of the gains from these pulleys comes from underdriving of all the accessories (15-20%).
However, we do not push underdriving for two main reasons. First, it is important to keep charging systems, air conditioning, power steering, and water pumps moving fast enough for every day driving. Second, not much horsepower is gained from extreme underdriving.
In most applications all of our underdriving is done with the crank pulley, not the accessory pulleys. This is done so maximum weight loss can be achieved at the crank where most of the horsepower gains are found.
- Real HP & torque gains across entire RPM range
- One of the highest HP/Torque per dollar gains on the market
- The broadest range of applications available
