KAVS R53 MINI Cooper S Reduced Supercharger Pulley Upgrade Kit Reviews

5 Rating 45 Reviews

So, what is a Reduced Supercharger Pulley?
Unlike a turbocharger, which is propelled by high-pressure exhaust gas, a supercharger is driven by a belt connected to the crankshaft. You, therefore, do not suffer the effects of 'turbo-lag' (where there are not enough exhaust gases to compress the quantity of air required lower down in the rev range). The MINI supercharger is the Eaton M45; which is a roots blower. This means that within the turbine housing, two specially crafted lobes with a minimal clearance of one another spin in order to compress air, which then passes through the horn, into the intercooler, out the other side and into the head and cylinder block. The way the lobes spin is that two cogs interlink at one end outside of the main air-flow path, and connect to a pulley on the outside of the turbine housing.

This is where it gets interesting.[...]

“Always important to maintain this and changing it is a good idea to do replace this on a ragular basis. With a quick message to the guys, they were able to very quickly give me advice on exactly what size was required.”

“Great package, simple to fit and everything works together perfectly. Belt tool is a necessity and simple to use (will need a small allen key to lock the tensioner off) Pulley removal tool was out of stock when I made my purchase so, used a cordless Dewalt multi tool to cut in to the existing pulley to release tension and then popped off easily. As always the service from Orranje was first class. Highly recommend”

“Transforms the car, supercharger starts boosting at lower revs, pulley is good quality and fits well, reccomend buying a puller to remove the old pulley”
