    2Rude Upgrade Question

    Thinking about upgrading to a 2rude. Would I run out of injector with my 48s? Also can I run my stock fuel pump? Had a bearing failure with my minirude and the whole charger is shot now.

    you will be fine with 48s,I dont think youll need a bigger pump,not with a Riva ECU and 08 fuel pump...BUT you may want to gauge your fuel pressure to be sure...I run a 2 Rude,50s at 8100 with no resource line connected to the fuel pressure reg. and a Rude fuel controller and i only need 56 psi of fuel pressure to feed it...and thats on an 06.

    Thanks! That's what I needed to hear. How much boost are you seeing?

    Yes the bosch 48s. Any problems with stock head gaskets or head bolts letting go at 15+?

    I have had zero issues running OEM gasket and bolts.
    If the head is flat with block you should be ok.

    Yep, 15lbs and 8600 RPM blew my first one. Have you checked the torque on your existing head bolts??

    Nope, my ski has about 140 hrs so i should probably check. Would it be worth upgrading to the Riva ones?

    What's the torque value when checking the head bolt tightness?

    Personally i would re-torque your head bolts to 92 Ft/Lbs..Just to be on the safe side...have heard of a few head gaskets letting go because there wasnt enough torque on the head...This is just me though..
