    New RR titanium valves

    here's a couple of pics of the new RR titanium valves. the intakes weigh 26 grams(stock is 50) and the exhausts weigh 22 grams(stock is 43)
    you use light retainers and SOFTER springs with these. the lower spring tension alone adds 6 hp and the engine will safely rev to 9500.
    sorry for the crappy pics but its all i have for now.

    I would think that "softer" means less spring pressure..
    That is a good thing as long as you can keep the
    valves under control.. And making the valvetrain lighter
    is 1 way to be able to use less spring pressure.
    That also means less power to spin everything, so more hp

    Running these and stock valve springs can safely rev to 9500

    The Riva springs have more tension on them.

    dear god....

    So why does riva do it this way?

    Because they are made to work with stock weight valves, not valves half the weight.
