Q: What is CPI?

A: Charge Pipe Injection (CPI) is our new proprietary system that allows you to add additional injectors to your boosted application with any standard 1/8" NPT female connection in your charge pipe or intake system.

Q: Is it expandable?

A: Yes, we have two types of injector bodies. The first has one input that can be run by itself or we have an injector body with two connections so you can daisy chain in additional injector fed from the same fuel source.

Q: What is required to run one of these injectors?

A: These kits are for boosted applications and you must have enough clearance to install the injector and fuel lines. We have provided measurements to assist you with this.

Q: How is it controlled?

A: At this time you must use a port injection controller such as a Split Second AIC1 or if running a JB4, you can use the BMS injector controller as well.

Q: Can I add an injector to my current current port injection kit?

A: Yes, you can connect the injector to the fuel rail if it has an available port such as the Fuel-It! port injection kits do.

Q: Can I use this without a secondary injector controller?

A: No, this is a PWM controlled injector that must be programmed.

Q: Is tuning included with this kit?

A: No, we do have a flash file that we will provide customers for their Split Second controller should they need it, but tuning services are not included with this kit. If you need additional assistance, our basic port injection tuning package can be purchased.

Q: What kind of fuel can I run?

A: These kits are compatible with methanol, ethanol, E85, race gas, and pump gas.

Q: Where do I connect to the fuel source?

A: That will vary by application. If running E85, most will tee in to their low pressure fuel line and if compatible use one of our fuel line adapters.

Q: Can these be used pre-intercooler?

A: Yes but we recommend using the 550cc injector and in an application where air temperatures may are above 300 degrees fahrenheit we recommend running methanol or high concentrations of ethanol in your fuel.
