Honda K20/K24 Underdrive Alternator Pulley 30% - Black

The T7Design Alternator Underdrive Pulley increases performance by reducing the force needed to overcome the inertia of the alternator during acceleration and gear changes, this will result in a snappier throttle response and more horsepower reaching the wheels.

Alternators, in general, have a broad generating power band with the Honda K20 alternator producing a reasonable output from just 1,500 rpm, with max output being produced from 4,000 to 18,000 RPM, with this latter figure technically being the maximum warrantied rev limit. In some applications, where the engine is spending most of its time in the upper half of its rev range, you simply do not need to drive the alternator at such a high speed. However, the only issue you would potentially face is a lower output at idle, in which case you may need to increase the idle speed to ensure the alternator is producing more current than is being consumed by the vehicles electrical systems. An underdrive pulley should also be considered if you have raised your rev-limit of your engine, for example if it is now 10% higher we would recommend fitting a 10% underdrive alternator pulley and so on.

ATTENTION
  • It is recommended to use an impact gun to remove the original alternator pulley.
  • Fits both models of Honda K20/K24 alternator.
  • For road applications we would not recommend going less than the 10% underdrive pulley, any less and you may find the OEM alternator cannot provide enough charge at idle with all electrical accessories turned on.
