PSE charges a core deposit on all exchange superchargers in the amount of $200 or $300 dollars depending on the model of your supercharger. We will either charge your credit card at the time you make your purchase or we will hold an authorization on your credit card. At the time your order is placed, PSE will determine whether or not to charge your core deposit upfront. This core deposit does not cover the cost of replacing your core. If you do not return the core supercharger you will be charged an additional $200 to cover the costs of replacing your core.

CORE MUST BE RETURNED WITHIN 14 DAYS UPON RECEIPT. Upon Customer's Core return we will inspect your core and you will be notified if your core is damaged beyond repair. The $200 or $300 dollars will be retained and charged on your credit card if core is damaged. If your core is GOOD, authorization will be released on your credit card.

PSE does not provide a 100% core refund for cores that have been opened and disassembled in any way. PSE performs many different inspections and measurements to your core supercharger that greatly reduces the reassembly time. Most often disassembled cores arrive to our facility damaged preventing the supercharger from undergoing normal remanufacturing procedures. Supercharger cores that are not eligible for a full refund are ones that the front nose bearing has completely failed or exploded to where the pulley is wobbling. Core superchargers that are damaged beyond repair will not be eligible for any refund.

PSE charges a $75.00 inspection fee for all superchargers shipped in for consideration of remanufacture or repair and the customer declines repair. Customer is responsible for paying all shipping costs to return unassembled supercharger back to the customer.

PSE Blower Service is not responsible for you or your repair technician’s misdiagnosing any repair on any vehicle. I hereby authorize PSE Blower Service to charge my submitted credit card only for the purchase of phone authorized orders and agree that this purchase will be treated like cash and handled like cash. Any and all discrepancies will be handled as cash and all customers wave their right to back charge or charge back any amount charged on their credit card for any reason. All Superchargers shipped from PSE must have the core returned within 14 days of receiving it, or your core charge will be forfeited to pay the cost to replace it. NO Exceptions!!!
