Thanks you all have been very helpful now just gotta pick a good size.

 

There are two ways of adding fuel. The better way is to extend the duty cycle of the injector. The other way is to increase the pressure in the fuel rail.

The SC kits both increase the FPR pressure and so get away with no injector duty cycle control. But you can only increase the pressure so far and it is a rough method.

In reality most kits use both. Even the stock FPR is boost related, but at a ratio of 1:1. The Comptech is 6:1. I think my SARD unit is set to about 2:1. But most of the control is by injector phase control. I use 440cc injectors with 8lbs of boost.

 

AUSS2000 what is your injectors duty cycle at?

 

 

Not sure at present. I'm shortly to do some more mods and I'll find out then.

 

nice keep me posted
