Working out restrictor size for an Audi RS4

[rs4steve]

Hi

I'm trying to work out the correct jet and restrictor size but the figures I'm getting dont seem right. The car is a 2.7 v6 twin turbo running standard 380bhp, the injectors are 480cc standard. I have to run two jets as it has two intercoolers. Do they both need to be .7mm? Or both jet sizes totalling .7mm?

The wording in the HFS-3 fitting guide states "First work out the total fuel flow by adding up the capacity of the fuel injectors. Multiply the result by the prefered %." Is that all 6 injectors?

Any help working out the jet size would be appreciated.

Cheers

Steve
