Boundary High Flow Anti-Cavitation Oil Pump Backplate for Mazda MX-5 NA NB

£127.99 inc. VAT

Improve your stock oil pump, maximise flow.

Available to order — 1 overdue from supplier

Take your standard oil pump, throw in a set of boundary gears (checking tolerances of course!) and bolt it back together with one of these and get near stage 2 performance for considerably less.

We took the standard BP backplate and threw it away. This new pump backplate was redesigned from the ground up to be better in every way. It starts with the way every motorsport component should be, carved from Chromoly Steel billet. From there we added an all-encompassing flow package to reduce cavitation and aeration of your oil. All BP motors will benefit, but those running more then 7500 RPM will see improved bearing life and oil pump life that a properly designed backplate will give them.

Features:

  • Intake volume increased by 80% reducing fluid velocity, pressure drop,?and cavitation.
  • Intake port 3D contoured to help fully charge the gerotor’s mesh further reducing pressure drop and cavitation effects in the teeth.
  • Exhaust port volume increased by 20% decreasing pressure loss from flow exiting the gerotor.
  • Port areas tightened to add flow direction to the fluid and rigidity.

Please note this backplate does not work with VVT oil pumps

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.
