Capture Significant HP Gains With Aftermarket MINI Supercharger Pulleys

The initial era MINI Cooper S, crafted among 2001 and 2006, is run by a supercharger. The supercharger in the early Cooper S supplies more oxygen to the motor and, consequently, much more gasoline. This improve in distribution of oxygen and fuel to the Cooper S’s motor yields higher power output. On the other hand, there is continue to a lot more electricity attaintable because of to MINI aftermarket parts like the lessened-sized supercharger pulleys.

Generally, aftermarket pulleys occur in a few distinctive variations – 15%, 17% and 19%. What do these percentages mean? They simply just refer to the size variation amongst the aftermarket and inventory pulley. For occasion, a 15% pulley is 15% scaled-down than the a person that arrives stock in the MINI. The smaller sized the pulley, the smaller the belt and, the scaled-down the belt, the quicker the turbines in the supercharger spin. When the turbines spin quicker, far more oxygen is provided to the motor and the motor yields a increased ability output. What does this amount of money to? A lot more torque and horsepower.

In the R53 MINI Cooper S, hope to capture a get of about 15 HP soon after installing a 15% pulley. (Recall, the percentage of the pulley does not correspond to the attain in HP – this is just a coincidence.) With the 17% hope a 20 HP increase and, with the 19%, a 25 HP improve. All HP gains change based mostly on the problem of the MINI and beforehand-added overall performance parts.

When looking at the price tag of an aftermarket pulley – $100 to $150 – and the amount of money of additional HP attained, it is really a single of the most charge-productive upgrades in the R53 MINI aftermarket. MINI general performance elements like bulky intercoolers and exhausts price about a grand and don’t offer you the HP boosts that general performance pulleys do. In essence, you get an extra 15-25 HP with a two-pound pulley and a lesser HP acquire with several overall performance pieces that are heavier and much more expensive. This is why several lovers are rapid to make an aftermarket pulley set up their 1st MINI upgrade.

But which pulley need to you purchase? The 15%, 17% or 19%?

By seeking at the HP gains made by each and every pulley, it appears very best to go with the 19% for the greatest HP gain. The 19% pulley, nevertheless, is not the most simple. The 19% provides the most enhance, but also delivers the most put on to the vehicle’s internals. The 19% is good for quick circuit races or time trials whilst the 15% is excellent for endurance, long races and daily ability cravings. Placing this into perspective, the 17% is a compromise involving the two. It delivers an maximize in HP more than the 15%, but triggers internals to have on a bit more rapidly. In general, the 15% is the most advisable pulley for each day drivers of the R53 MINI Cooper S looking for a considerable electrical power gain.
