    bigger SC wheel on 08'rxtx

    I have found a cheap super charger wheel for my rxt-x. its a 9-fin (un-known brand). will i need to up the fuel pressure (with a rising rate reg) to run the bigger wheel safely? or will the stock engine run ok with the extra 3psi it will give..?

    Be safe and add a wideband to monitor your AFR's. Then you will know if you need to adjust the fuel, but I'm going to say you probably should add a RRFPR when upgrading your charger.
