    Supercharger question?

    I have 2006 RXT with a XS external intercooler (with a few other things). I don't want to change anything internal in the engine. What supercharger would give me the best bang for the buck? X charger? Rude? Green wheel, S3, ???? With so many options, I'm starting to loose track. I'm getting a Rude rising rate fuel pressure regulator & I want to max out my supercharger (without breaking the bank). I don't race, but I'd like to try to keep close to my RXP stage 2 buddies. Any suggestions?

    Since you have the RRFPR go ahead and add 42 lb injectors and the 2rude charger. You will be very pleased with the performance.

    also, if you add the 2rude supercharger you will want the 15/20R impeller. You will still need to add some pitch to the trailing edge of the 15/20 to keep off the limiter.

    Thanks Jerry. What kind of top end speed do you think I can achieve with this setup? Will I have to zip tie my wrists to the handle bars to hang on? I'm a big guy so gravity works in my favor.

    with the 2rude and 15/20 i would be real surprised if you didn't see 73-74 mph.

    You will want to pitch the 15/20 accordingly to run with the 81mm ring.

    No injectors needed as well with the 2Rude

    How about for a Rude 1? If not, what do you suggest setting the base pressure at with stock 38s?
