RACEWORKS INJECTORS BY SIZE
Find your injectors by Size .
Use our Upgrade guide to nominate your engine and power requirements.
Use the search function (link at the bottom of this page) to select a suitable performance injector and injector accessories from the Raceworks range for your application.
Power figures which have been quoted are to be used as a guide only.
For naturally aspirated vehicles running a base fuel pressure of 3bar they are fairly accurate. For naturally aspirated vehicles running a base pressure of 4bar add a further 10% to the power figures quoted.
For forced inducted vehicles power figures quoted are based off a fixed fuel pressure of 3bar therefore in reality the injectors will support more power as fuel pressure increases with manifold pressure allowing the injectors to flow more than has what been accounted for in these calculations. In these instances we recommend you add a further 10% to the power figures quoted for every bar of pressure the fuel system will flow at above 3bar.
See below for example
Power figures quoted
Normally Aspirated 575RWKW
Normally Aspirated E85 420 RWKW
Normally Aspirated Methanol 290 RWKW
Forced Inducted 440 RWKW
Forced Inducted E85 315 RWKW
Forced Inducted Methanol 145 RWKW
Base fuel pressure of 4bar (Add 10% to the above figures)
Boost pressure of 1bar (Add 10% to the above figures)
Final estimate
Normally Aspirated 690 RWKW
Normally Aspirated E85 505 RWKW
Normally Aspirated Methanol 350 RWKW
Forced Inducted530 RWKW
Forced Inducted E85 380 RWKW
Forced Inducted Methanol 175 RWKW
Figures stated are what the injectors will support. NOT what your vehicle will make by upgrading to these injectors. Raceworks will not be held responsible if your injectors are unable to support the power stated. For more information it is recommended that you discuss with your tuner.
All power figures have been rounded to the nearest 5KW. The following drivetrain losses have been used in these calculations
Front Wheel Drive 15%
Rear Wheel Drive 20%
All Wheel Drive 25%
Note there are exceptions to this such as Toyota MR2 which is rear engine/rear wheel drive and a loss of 15% has been used in the calculations.
Where extended nose injectors have been used in a particular vehicle from factory only extended nose injectors have been recommended as replacement and extended nose injectors have only been recommended for these applications even though they can be used in many applications that run standard nozzle injectors from factory. All Raceworks injectors are High Impedance and can be used in both low and high impedance configurations. Note when installing onto a vehicle that has low impedance injectors from factory it is recommended that resistor packs are disconnected/bypassed. Again consult your tuner/engine builder.
Should you have an engine that is not listed here and would like info on the compatibility of Raceworks injectors please contact your nearest stockist.
