Fuel System – If you want more HP, you’ll need to flow more fuel!!

Fuel Injectors


We stock and supply a range of High and Low impedance injectors for a range of road and race applications, available in top and side feed to suit your vehicle.

To help you choose, consider how much HP you want per cylinder. Multiply that number by 4.7. The answer should give you a figure in cc/min for each injector. For engines with higher RPM capability (8000+) please email for advice

Performance and Replacement Fuel pumps.

Any engine upgrade to power levels greater than 25% of the manufacturers production figure should always include additional fuel flow. Without it you’ll never unlock your engines potential, and risk some expensive bills to boot!

All our pumps are designed to deliver a significant flow increase at factory operating pressures, whether 2.7, 3.5 or 3.8 bar, but also at elevated rail pressures of 5.0bar + (when boost pressure is applied to the regulator)

If you are unsure what flow delivery you will require, please ask ‘
