Installation of our Overdrive pulley is completely reversible! \u003cbr\u003e- Converting to a single piece, solid crank pulley without the rubber isolator will prevent separation of the crank pulley and damage to your motor and\/or accessories while reducing the rotating mass of the engine's rotating assembly will also free up horsepower. \u003cbr\u003e- The JHM Overdrive Crank pulley achieves the same supercharger speed as a smaller supercharger pulley while increasing the total amount of belt contact in the belt and pulley system. When you decrease the size of the supercharger pulley there is less surface for the belt to grip the pulleys which can lead to slippage. Our JHM Overdrive Crank Pulley increases grip and prevents slippage. \u003cbr\u003e- Our JHM \"HD\" Overdrive Lightweight Crank Pulley is anodized black to look stock and blend in. \u003cbr\u003e- Though this is not recommended, we have had independent reports from our customers who have used our JHM Overdrive Crank Pulley along with a smaller, aftermarket supercharger pulley to \"double up\" and spin the supercharger even faster.

If you already have a smaller supercharger pulley or you are looking to upgrade your crank pulley without requiring a software change, see our JHM Lightweight Crank Pulley for the 3.0T. However, a current popular modification is to \"double up\" or run \"dual pulleys\" which means running a smaller supercharger pulley in conjunction with an overdrive crank pulley. However, following the launch of the JHM Overdrive Pulley has been a flood of other overdrive pulleys on the market that combined with a smaller supercharger pulley will spin the OEM Eaton 1320 Supercharger far outside of the designed efficiency range which can result in a huge loss of reliability and longevity. If you decide to go with a \"dual pulley\" setup, using the JHM Overdrive Pulley will be your safest bet.\u003c\/p\u003e\n\u003cp class=\"tgk-p\"\u003eJHM has been making Lightweight Crank Pulleys for Audis since early 2009.

That was followed by the 6-rib pulley systems we developed for our B6-B7 S4 and RS4 Supercharger Kits. After the release of the Supercharger Kits, we came out with a Lightweight Crank Pulley for the B8-S5 4.2L, then the 2.7T, the 3.0L V6, and the 2.0T FSI.
