The Eaton M45 Supercharger used on the MINI R53 and R52 "S" model Gen1 MINIs is normally rated for 100,000 miles, but some of these units can go further or shorter in mileage. One common issue is that the rear gear assembly runs dry because of a bad seal. When the rear seal fails, the supercharger oil is sucked out of the supercharger, leaving the PTO gears dry causing them to fail. When this happens the water pump stops running causing the engine to overheat.
These rebuilt units are fully rebuilt with: new PTO gears, bearings, and seals to standards that are higher than other rebuild companies out there.
All Detroit Tuned Superchargers come with new:
Nose Cone Bearings
Nose Cone Seal
Rear Bearing & Seal Retainer System
Heavy Duty Extreme use Seals that Exceed OEM Quality
High Temp Supercharger Lubrication Oil
About the rebuild:
These are rebuilt locally for Detroit Tuned with new parts that have been designed by DT. These are now in their 3rd and final rear gear design that has a new and better tooth design that is not only quite but has less play in them, and are also hardened them for a longer life. DT also redesigned the seal capture system for the rear bearing so that the fluid can't leak out again. What they have learned from reviewing dozens of failed units is that the rear gears failed due to lack of oil. The oil leaks out the back due to a seal failure and causes the bearing to move around in the back plate where it meets the water pump. This was all due to how Eaton rolled the lip over to capture the bearing for the rear gear. To top it all off, DT added new fluid to both the front and the rear that is far superior to the GM fluid it came with. This makes a complete ready to bolt on unit that requires nothing for the customer to do other than bolt it on and drive away!
Lets make it faster!
DT Superchargers can come with a stock size pulley installed read to go, but for a few dollars more you can have a 15% or even a 17% pulley installed. If you're adding a pulley, don't forget a new shorter belt and a set of colder plugs to round out the performance needs for your MINI! If you already have an under drive pulley on your current supercharger, take it off before shipping the core back. Select the "No Pulley" option and the supercharger will come ready for you to install your under drive pulley!
Also think about a new Supercharger Intake Gasket, Water Pump, or Water Pump O-Ring (fits on the block connection), while you’re at it!
If you're comparing this rebuilt supercharger to any other units on the market from the 3-4 that will usually come up on a google search please consider that this particular rebuilt MINI Cooper supercharger has numerous custom tweaks to gears, fittings, seals and overall design that are not found on any other superchargers. The Detroit Tuned superchargers are specially made JUST for them and no other rebuild companies offer the same product. As a result these are by FAR the best value on the market. There are some that can be found for a few hundred less and many that are hundreds more but this is what you need.
