We are all looking to slim down these days, even cars have joined the ranks of those trying to shed a few pounds. Weight is the key to performance, and the less you have the better thing perform. Neuspeed is like the Weight Watchers of the racing world - always looking for ways to make a car lighter and go faster.
By making the pulley 20% smaller and 5 times lighter than the factory pulley, it takes less kinetic energy to spin a full revolution. The 2.0 TSI crankshaft pulley design is very complex design so ensure the reliability and durability Neuspeed machined their power pulley from a special 7075-T6 aluminum alloy do give all the strength of OEM steel but without the weight and hard anodized it to prevent wear.

- NEUSPEED Power Pulley 13 ozs.
- 20% Under-drive reduction
- 7075-T6 Aluminum
- Hard Anodized
Parts: Crankshaft pulley, belt, crankshaft bolt
Tools: 17mm wrench, T25 and T30 Torx, 24mm socket, ratchet, VW Tool T10355 Counter Holder, breaker bar, torque wrench
1.) Putting vehicle on a lift will make the job easier, because a standard jack and stands will not allow the vehicle to get high enough off the ground.
2.) Remove lower splash guard and passenger side lower inner fender liner with a T25 Torx to expose crankshaft pulley.
3.) Disconnect the passenger side lower intercooler hose from turbo discharge plastic pipe.
4.) Unbolt the two T30 Torx that hold the plastic turbo discharge plastic pipe to the engine.
5.) Disconnect the clip to release upper rubber hose from turbo.
6.) Using the T30 Torx, remove discharge pipe support bracket from engine.
7.) To remove the belt, use the 17mm wrench to rotate idler pulley center bolt upwards to release tension and remove ribbed belt.
8.) Using the 24mm socket on crankshaft pulley bolt, rotate engine clockwise to the "TDC" position (Top Dead Center). The notch on the pulley must line-up with the arrow marking on the timing chain cover located on top of the side of the pulley.
CAUTION: THE CRANKSHAFT MUST NOT BE MOVED OUT OF THE "TDC" POSITION WHEN THE PULLEY AND BOLT IS REMOVED OR ENGINE DAMAGE WILL RESULT. DO NOT LET ENGINE TURN WHEN REMOVING OR TIGHTENING PULLEY BOLT.
9.) Remove pulley bolt using 24mm socket and T10355 Counter Holder tool to hold engine from turning.

Installing Neuspeed Power Pulley
10.) Use a little oil on the timing cover seal. Install NEUSPEED pulley matching up tooth contour on pulley with crankshaft chain sprocket. While holding against chain sprocket, install new bolt supplied and hand tighten.
11.) Torque bolt to 150Nm (111 ft. lbs.) + 90? (1/4) turn with torque wrench and T10355 Counter Holder tool. Then install supplied ribbed belt.
12.) Reinstall discharge pipe mounting bracket, discharge pipe, fender liner and lower engine cover.
13.) Carefully check completed installation to be sure all fasteners are tight, the belt is correctly seated in grooves of each pulley, and that nothing interferes with the pulleys or belt.

Having dynoed under drive pulley systems in the past I was not expecting to see any big horsepower and torque gains. In general you don't see the gains on paper - it's more of a real world experience to know that the pulley is working. It's like taking antidepressants. No lab test will show a change in levels but you will feel fantastic.
The first full throttle sprint down the 101 freeway is where the Neuspeed power pulley really shined. The motor did not struggle as moved through the rpm range and the DSG transmission seemed to shift little smoother. On the dyno, we saw gains of 1-2 hp in the lower rpms with a max of 3-5 in the upper rpm range my butt dyno felt more like 20 hp.
