BOFI Racing 150mm Supercharger 6PK Overlay Pulley for Mazda MX-5 NA NB

£219.98 inc. VAT

The 150mm supercharger overlay pulley overdrives the supercharger to spin it faster and make more boost. The diameter is increased from 130mm to 150mm, increasing the RPM of the supercharger to 16,615 RPM at the 7,200 redline. Increasing the size of the crank pulley means the larger supercharger pulley can be retained, reducing belt slip. Your Mazda MX-5 will require re-tuning to extract maximum performance from the increase in boost and to prevent it from knocking.

To make the most of the overlay pulley we recommend installing a larger 230mm intercooler to keep intake temperatures down and make maximum power. The overlay bolts straight over the existing crank pulley from 94-05 cars that have a flat-faced black steel pulley. If your pulley is a brown cast-iron pulley with a? raised mounting surface, it can be swapped out for the black steel pulley.

Please note, to use this overlay pulley with NA 1989-1998 1.6 cars you will also need to change the alternator, water pump pulley and alternator belt to 4PK versions as fitted to MK1 1.8s.

Warranties cover defects in materials and workmanship only. Warranty is for replacement of a similar product, repair of the original product or refund of the purchase value only and excludes all labour and incurred charges including towing, fitting, inconvenience, and purchases of other manufacturer's products. The warranty is good for the period stated in the additional info tab from the date of purchase. Mileage warranties are for road use only and proof of mileage is required. Products must be installed by an independent experienced professional mechanic and the suspected defect must be present at the outset. The warranty does not cover damage caused by incorrect installation, failure to comply with the maintenance requirements of the vehicle, processing or otherwise changing the product, ordinary wear and tear, or any other external influences. Warranties are invalid if the product is used for racing, rallying, drifting, track days or any other form of motorsport or competition. Please refer to the manufacturer's own warranty documentation for more information.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
