looking for 300-400whp range...

I have 440's. They should be maxed out or close to maxed on a setup like this. t3/t04e 57trim .48ar turbine blows 50 lbs/min 640cfm I want a set of injectors that will be at about 70% duty cycle with turbo at maximum efficiency. Also, does anyone have any links to a good injector sizing calc?

 

650 or higher??

 

just us 880s and not have to worry

 

anything above 680 cc will give you want you need in that power range. if you plan going higher in the future do as one user said get the 880cc if you can control it with your ecu
