I am interested in learning more about injector sizes and yes I could just speak to a tuner but I like to understand these critical things as well.
For a hybrid RS3 it is pretty standard to use 980cc injectors.
Someone pointed me to this simple calculator:
Having done a calculation with a target crank hp of 750 on petrol it states 899 cc per min on 85% duty cycle, which sounds pretty close.
Now if I wanted a target crank hp of 825 on E85 it states 1286 899 cc per min on 85% duty cycle,
I am probably going to ask the obvious here, but am I correct in assuming I could fit 1300 cc injectors to run either E85 or pump fuel?
If this is correct would it run badly when on pump fuel with the bigger injectors due to their duty cycle being much lower?
Currently I am running Sharps Motorsports 980cc and I have been considering moving over to Injector Dynamics injectors due to the very positive reviews and options. They do both 1050 an 1300 sizes for the RS3 Daza engines.
I thought it would be good to discuss as I am always up for looking into what new technology is out there being used.
