SR013_019VP.jpgToday, we get a look at the changes that help the 2013 SRT
    Viper make an awesome 640 horsepower with the help of the Viper’s Chief Powertrain
    Engineer Dick Winkles.  While many
    expected that the 2013 Viper would sport a larger engine than the 8.4L V10
    offered in the 2010 Dodge Viper, with rumors that an 8.7L mill was on the way,
    the 2013 SRT Viper makes all of that power with the same displacement as the “old”
    Vipers thanks to new materials and new components.

    This new 2013 SRT Viper engine video begins with Dick
    Winkles talking about the specific features that separate the 2013 Viper V10
    from the similar engine used in 2010 when the Viper was last available as
    new.  The new Viper features a new,
    higher flowing intake manifold that works with a new camshaft profile to make
    more top end power without hurting low end acceleration.  Items like sodium filled exhaust valves and
    new forged pistons help to make the new engine lighter and more durable while
    an enhanced cooling system ensures that the 640hp engine doesn’t get too hot
    during cruising – or track time.

    Mr. Winkles goes on to discuss how the 2013 SRT Viper will
    continue to maintain and defend the records set by the last generation Viper –
    almost eluding to the fact that the company had plenty left in the tank when
    reclaiming the Nürburgring record.
