    Need Some help on a Mod Setup: Injectors???

    I am currently building on top of a Riva stage 1 setup on a 04 RXP and I am adding a greenwheel charger and a Riva Intercooler (Gen 2). I have read that the injector setup for this setup are 42's.

    Is that correct setup?

    Can I use the stock fuel pressure regulator?

    Will the mix be slightly rich in this setup (assuming I just change the injectors)?

    My first setup was exactly that Greenwheel , external intercooler, and 42lb injectors it ran perfectly up here in the Canadian cool summers and cooler lakes. It was always crisp and ran perfectly. You will also use the stock pressure regulator and stock fuel pump.

    One more question I forgot to ask .......... I would still have a stage 1 prop. Would I need to re-pitch for the final setup?

    You would prabably have to see where you are at in terms of rpms and go from there

    Your best bet is to go with a 15/20R.

    You can pitch up your 14/19 to a 15/20 but it won't be the same as the root angle on the 14/19 is unchanged. The 15/20 will be 1+ mph faster than a pitched up 14/19 at the same RPM.
