Reduction Drive System for the Type 1 VW!

The NEW Series 3 Reduction Drive is available from Valley Engineering in drive ratios from 1.6:1 up to 2.0:1. Props used vary from 72 inch x 40 inch pitch up to 84 inch x 56 inch pitch. It greatly improves the take off and climb performance of any high drag VW powered aircraft that needs more thrust.

On a 2180cc engine with a 1.6:1 drive and a 72 inch prop, you will see about 350 lbs. of thrust. On a 2.0:1 drive and an 84 inch prop will pull about 450 lbs. of thrust. You get the idea! (A direct drive VW with a 62 inch prop will pull about 215 lbs. of thrust.)

The Series 3 is driven off the pulley end of the cranshaft. All the standard accessories bolt right on the motor. Add a Diehl Accessory Case, magneto, starter, or secondary ignition.
