VIS Motorsport oil pump balance shaft delete kit
2.0 TFSI EA113 . Get the most out of your engine.
Free up excessive engine rotational drag by removing the balance shaft assembly from your EA113 engine with the VIS Balance Shaft Delete Kit. The heavy balance shaft assembly (An ASTOUNDING 19 POUNDS!!!) can be easily removed allowing your engine to respond faster.
This will work on all EA113 2.0 TFSI engines
There are no adverse effects caused by removing the balance shafts. Adds REAL horsepower and allows engine to rev FASTER!!! Install can be completed with basic hand tools in about 30 MIN
Removing the rotating mass of the OE balance shaft frees up a few extra horsepower but more importantly, makes your engine rev FASTER. You also gain extra oil capacity and oil starvation prevention to keep your engine healthy longer and want quicker RPM gain, look no further than the VIS BS DELETE KIT FREEWHEEL

The Volkswagen/Audi 2.0T FSI engine has a weak point: Its counter-rotating balance shafts wear out prematurely. If your friends went through this, you already know the shafts are stupid expensive to repair, up to $1,800.
This is an alternative to cut the cost of eventual shaft and oil pump replacement
kit eliminates the problem
What is an oil pump? Quite simply, it’s the single most important mechanical component in making sure every crucial moving part of your engine is properly lubricated, no matter how hard you drive. Getting oil to your engine’s moving parts reduces friction to an all-but-harmless level. There’s always some friction, which is why engines wear out – eventually. But without proper oil flow from a quality oil pump, your engine is toast before you know it – very expensive toast.
It is important to check the original crankshaft gear

Balance Shaft Removal
Balance shafts are commonly found in inline four cylinder engines such as the EA113 which, due to the asymmetry of their design, have an inherent second order vibration (vibrating at twice the engine RPM) which, contrary to popular belief, cannot be eliminated no matter how well the internal components are balanced. This vibration is generated because the movement of the connecting rods in an inline engine is not symmetrical throughout the crankshaft rotation; thus during a given period of crankshaft rotation, the descending and ascending pistons are not always completely opposed in their acceleration, giving rise to a net vertical inertial force twice in each revolution whose intensity increases quadratically with RPM, no matter how closely the components are matched for weight.
The EA113 found in are equipped with 2 balance shafts. The left balance shaft that's directly connected to the oil pump driven gear and the right balance shaft that's driven by the balance shaft gear over the oil pump sprocket. Two balance shafts rotate in opposite directions at twice engine speed. Equally sized eccentric weights on these shafts are sized and phased so that the inertial reaction to their counter-rotation cancels out in the horizontal plane, but adds in the vertical plane, giving a net force equal to but 180 degrees out of phase with the undesired second-order vibration of the basic engine, thereby canceling it. The basic problem presented by the concept is adequately supporting and lubricating a part rotating at twice engine speed at the higher RPMs where the second order vibration becomes unacceptable.
So why do it? The main reason for balance shaft elimination should be reliability as power gains are minimal. As you can see it inherits a potent lubrication problem and unlike the name suggests it's job isn't to balance but merely masks off the vibrations. Silent shaft is a more appropriate term but not used as commonly. Although the chances are slim, it's still one less part that can fail.
⦁ More HP to the wheels
Completly reversible to stock
No need to remove oil pump to install
⦁ Zero chance the balance shaft belt will fail and kill the timing belt
⦁ Zero chance the balance shaft bearings will fail and damage the rest of the motor
⦁ More oil pressure to the rest of the motor
If in doubt please check your engine code, in most cases your vehicle model and engine codes can be found on a sticker on either the cam belt cover or white sticker found under the carpet in the boot.

balancer shaft gear (AGW) is
driven by a decoupled drive chain sprocket.
The function is
similar to that of a dual mass
balancer shaft gear was taken over from the
common FSI engine. However, it had to be
modified as follows:
Decoupled drive chain
sprocket in balancer
Separation of splines and compensation
weights to increase balancing efficiency
Oil pump with greater gear width
Pressure relief valve, controlled purely by oil,
with oil control in vicinity of
oil pump, integrated in balancer shaft housing
Strength optimised pressure cast housing
Bearings of balancer shafts
located directly in aluminium housing
The improved smooth running of the crankshaft in the lower speed range leads to a considerable increase in chain forces in the balancer shaft gear.
With a relative crankshaft vibration angle of 0.8° onthe normal FSI engine, the increasedcrankshaft vibration angle of 2° onthe turbocharged FSI engine ismuch more noticeable.
Due to theincreased load of the chain drive,
the chain would be subjected to
increased wear if there were no countermeasures.
Therefore, there are curved springs in the hub of the
chain sprocket. These decouple the input shaft
of the balancer shaft gear to the crankshaft.
