    help needed with X-charger on 04 stock except GH exhaust?

    My stock SC clutch won't come in spec for slip, so likley going to run the X SC I have.

    Want to run stock IC, injectors, fuel pump with GH waterbox. Any issues to worry about? Won't run lean will it?

    Assume it needs a 14/19?

    Makes sense, but thought Jerry indicated it didn't need 42's

    Hi Guys,

    I'm going to be running my 2006 RXT a X-SC with the last upgrade wheel and front housing(Mini) Riva Gen II IC 15/22 2mm 42lbs inj. and RRFPR setup at 60psi. I was running before X-SC with first upgrade wheel and 50's lbs injectors and RRFPR setup at 53psi. My fuel tank was going fast. I'm waiting for some other parts to come in and would be doing some testing with both 42's and 50's.

    You cant really use the plugs on the 4tecs to gauge AFR even when running bang on they will look lean on the plug. Only way to tell is with some sort of AFR metre. Cheap insurance when compared to a re-build. R88

    We did an X charger and Riva rear air intake on an otherwise stock RXP. With the RRFPR, it was still a little lean. I'd say run 42's OR the RRFPR for sure. BTW, it needed a 15/20R prop and ran 75-76 mph.
