    Does anybody know who makes riva/ s pistons? I need a 20 over and say it will be weeks
    because they are out of stock and are having them made.

    MTC is the maker of Riva pistons and is located down the street from me. They make pistons per demand but you might be able to speed up process by contact.

    +2 we all love the 9.5's. They give the ski a little more snap

    What are fueling requirments for 9.5s at higher RPMS??i heard you may not want to run pump gas on 9.5s if you have shitty gas....true???false?? reason im asking is my motor is apart and im going .010 over and was contemplating on going with 9.5s and spinning 8550 rpms....is pump gas still safe to run with that kinda compression and RPMs???

    Thanks

    What boost and ECU are you running. That is going to decide what fuel you will need. I Know Duke has done a fair amount with these pistons with very good succes.
