Fuel Injectors

Racetronix Fuel InjectorsThunder Racing offers a variety of fuel injectors in different flow ratings to fit just about every application.  50lb/hr and larger injectors are dynamically flowed and matched to within 1% by Racetronix on their state-of-the-art computerized injector flow bench. Flow matching and cleaning services are available for smaller injectors as well.

Performance advantages over pintle injectors (i.e. Ford / Bosch & Accel types) as listed by Delphi:
• The flat mating surface ensures that no excess fuel is present to evaporate and therefore, no deposits or clogging can occur.
• Longer service life
• High-speed action allows wider dynamic flow range for improved idling
• Quieter operation
• Revolutionary design resists build up deposits which can affect fuel flow
• No Fuel leakage for quicker starts

Why Buy Racetronix Flow-Matched Injectors?   Racetronix flow-matched injectors are grouped to within 1% tolerance using Racetronix custom computerized injector flow bench.  Unlike companies that claim they sell "flowed-matched" injectors, Racetronix starts with large quantities of injectors, which come from the factory in lots that may vary in flow by as much +/- 5%.  Racetronix injectors are statically flowed and dynamically flowed at various RPM's and pulse widths. This injector flow data is transmitted into a computer database which sorts the injectors into 1% tolerance groups.
