The 2013 SRT Viper engine broken down by an SRT engineer

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.
