Supercharger Rebuild Service
Free Insured Shiping back to You!
No Up Front Core Charge!
With more MINI Cooper S owners keeping or buying high mileage R53’s the Eaton M45 Supercharger will need service sooner or later.
AutoXCooper has partnered with a proven Midwest Machine Shop with a long track record of supercharger service and able to meet our high standards.
If you have priced or had to replace your Supercharger you know the costs add up quickly.
We have found a better way to get you a “like New” supercharger without the high costs.
We can also rebuild the PTO, Cone and Coat the Rotors.
Since you won't be able to drive your MINI without the Supercharger we will have a completely rebuilt unit ready to ship out most of the time. That's right send us your SC and once we inspect and know we can use it to replace the unit in stock we'll ship out the replacement within 24 hrs. This reduces your downtime with a small investment in overnight shipping.
Email or call to check stock, pull yours this weekend, ship it Monday, we get it Tue/Wed, we inspect it, ship yours Tue/Wed/Thur, you have a bolt on ready SC on Friday.
What if you know your SC is not going to be a basic rebuild or you want “your” SC back. No worries we can still turn around most SC jobs in 5-7 days. We offer a Rescue & Repair Service for badly damaged superchargers. Note we can’t repair damaged body units. Just ship it into us we’ll inspect it and provide a full report with pictures of your SC and commit to a price to repair it.
All prices come with FREE Insured Shipping in the lower 48. All others please email full address for shipping rates. We only use the very best parts, seals and such on all rebuilds. Keep in mind it takes hours to remove and replace the MINI Cooper SC. If you’re paying $100 an hour in labor we encourage you to get the SC and PTO rebuild to ensure you only pay labor once.
Best Value SC and PTO rebuild $895.00
Supercharger rebuild (no PTO) $649.00
Just the PTO rebuild $325.00
Just Snout rebuilds only $199.00
Coating Rotors or Inside of Case $127.00 each
Older Superchargers with old or chipped rotor coatings will need recoating for an extra $127.00 (our cost) and invoiced only if needed and paid before work begins. We can also cost the inside of the case if you like.
Rebuild kits for the DIY owners are ready to ship. Email or call for pricing.

What is done to the Supercharger?
M45 Supercharger Complete Rebuild Services. The rotor rebuild services include the replacement of ALL the seals with the best Viton double-lip spring seals. Bearings are replaced as needed with Nachi’. We then assemble the M45 to ensure proper clearances and precision rotor re-timing for optimum performance. Rotor Coating of the early M45’s is required at a small cost or if OEM coating is damaged.
We use Premium Viton double-lip spring seal for an excellent and inexpensive performance upgrade. This is especially important if you plan to run higher boost levels with your supercharger because the Viton seal can handle higher pressure and has a longer life than a standard seal.
If you are checking with other shops to rebuild your M45 be sure and ask them how they replace and then retain the “factory captive bearing/s and or seal/s”. Many shops will not remove a bearing that’s captive and if they do remove or replace it they use glue to hold it in. That glue will break down over time and may cause even more damage to the M45 case. We understand the temptation to save a few hundred dollars now, but that “savings” could end up costing you thousands more down the road.
To Coat or Not to Coat, Only if Needed
Maximize your supercharger’s performance potential by adding our High-Tech Coating to your rotors and or case. This special coating tightens up the case-to-rotor clearances. Yes, we are aware of the black coating on the Gen5 Eaton’s. It is a rubbery interference fit coating that wears in over time to establish the correct clearances for the rotors and case. Our coating is different than this. Ours is similar to the coating applied to piston skirts.
Compared to uncoated rotors, this special coating process significantly reduces metal-to-air heat-transfer. It also gives air a much smoother surface to pass over, creating less friction, thereby requiring less supercharger drive horsepower. That puts more horsepower to the rear wheels, where it belongs.
When we are preparing your supercharger for the coating process, we check the assembled supercharger's clearances first. Then we coat to achieve the correct clearances with our multi-layered dual coating process. After the rotors are coated, during reassembly, the rotors are set to optimum clearances related to your case. We can rebuild part or the entire supercharger, depending upon what is needed to bring it back to operating status. The rotor assembly will need to be rebuilt in order to coat the rotors.
There are two distinct coatings applied. The first coating is TLMB, a polymer for adhesion and wear-resistance. This coating will not scuff if the rotors make light contact at high RPM. The second coating is TLML, which is fused to the first coating. The second coating is slippery and will not gall. It provides a slick surface for the air to slide over to reduce friction and heat. The clearance between the rotor flutes and case tightens up because of the coating’s .005 thickness. Leakage is reduced, increasing the roots-type supercharger’s efficiency. Minor scratches can be rejuvenated with coating, as well.
Warranty Policies
Our rebuild and porting services/parts are backed with a 1-year unlimited mileage warranty. Warranty does not include damage caused by incorrect installation, misuse, and application for which product is not designed. Extent of coverage is only determined by Shop Foreman. Shipping costs related to the transfer of items will always be the responsibility of the consumer. Damage assessments will be thorough and specific so that any cause of concern is addressed clearly and accurately. The scope of the warranty work required is based on this assessment. We will work closely with any customer who has items of concern to work to resolve them to reasonable satisfaction. The warranty is voided if the application of the product by the consumer was the root cause of an item’s failure. We appreciate the opportunity to make right any issues that are our responsibility. If the failure is determined to be unrelated to our services rendered, we can often provide economical rescue repair services that can reclaim some superchargers after damage had occurred. We work very hard to provide the most cutting edge services and the best support for your technical needs. We are committed to taking care of our customers.
No Core Charge Qualifications
For any of the Eaton Rebuild Services, when no usable core is provided, there will be a core charge. The core charges will vary by condition of supercharger. This core charge applies to the Snout Rebuild Services because the Snout and Rotor Pack are what makes up the Supercharger. A Snout provided alone must be the one to be rebuilt. Shipping cost to send in the core and for return of the re-manufactured supercharger is the customer’s responsibility. The S&H cost will be calculated and added to the overall cost of the services. If a core is provided by the customer after paying this charge, all or most of the core charge will be refunded upon inspection of the core. A used core must be provided clean and in good working condition that can be rebuilt. We will not accept a core that has been painted unless it has been stripped down to the base metal. We will provide exact causes for any deductions in core refund. An example of what would be a deductible condition would be rotor damage from a bolt or galled and scarred case from excessive bearing failure and neglect. Call for more details if you have a core that you have questions about. Shipping insurance is optional when the customer ships the core but, highly recommended because the supercharger can be damaged in transit. We can not be responsible for uninsured or poorly packaged superchargers. Please pack carefully.
