ASNU S54 Injectors

£103.00 excl. VAT

All ASNU Performance Injectors have a multi-hole orifice cap, cut using the latest laser technology for greater accuracy and repeatability. Using this technology allows us to produce injectors with specific spray patterns and flow rates to meet the customers’ exact requirements. The seven-hole orifice cap that we use in most of our injectors in the lower end of the range (300-1000cc) offer an ideal combination of Fuel Flow, Fuel Distribution and Fuel Atomisation. The seven holes produce smaller fuel droplets that will burn more efficiently, giving more performance and more laps for less fuel. This is a critical factor and should be considered when comparing ASNU injectors to any other Performance injectors.

ASNU fuel systems and injectors are designed to be used in conjunction with standard grades of road-pump fuels, and certain race fuels with lubricant and corrosion packs (please enquire for details of tested and compatible race fuels).

The use of pure Ethanol, Methanol or other chemicals mixed in combination with standard pump gas or race fuels is not advised and will invalidate any warranty on all of our systems. Fuels with more than 50% ethanol, even with lubricants, will greatly accelerate wear and shorten system life as well as reducing the service life on any filters.

Our products are compatible with certain methanol blends containing an appropriate lubricant pack and E85 for race or drag events. When used with fuels that have Ethanol contents over 50% or fuels with a methanol content, the fuel system must be drained and flushed between events to prevent irreversible damage.
