Chrysler’s subsidiary Mopar decided to take Dodge Viper’s already terrifying 8.4-litre V10 and turn it into a drag-racing engine, and the result is an incredible 800 hp/940 Nm unit which is now on display at the 2011 SEMA. Aluminum block and cylinder heads, forged steel crankshaft and connecting rods and forged aluminum pistons are the most relevant features of this engine, which has been specifically developed to compete in drag racing.

Moper also confirmed that Viper’s standard 8.4 litre V10 will be subjected to further developments in order to make several different versions, including one suitable for off-road vehicles. Dodge Viper’s production is currently on hiatus as a new version of the mighty model is currently in the works, but it is nice to know that the heart of the last model will keep on pulsing in different guises.

According to Allpar.com, the development of Dodge Viper’s next generation is going in the opposite direction of what all the modern trends of the industry would dictate. It is reported that the new Viper - which is expected to debut in 2012 as a model year 2013 - will use a bigger version of its signature V10 engine, going from the current 8.4 litre displacement to an unprecedented 8.7. The famous American coupe will also feature many technical upgrades, while the adoption of Fiat’s MultiAir system is yet to be confirmed.

With an extra 0,870 cc per cylinder (or, as the Americans say, 0,531 cubic inches) this engine is bound the become the biggest engine that Chrysler ever put on a production car. The power delivered should be in the 700hp area, although - unlike all previous versions - an ESP system will put a bridle on all that might. Rumor has it that a V8 version - probably equipped with Hemi 6,4 litre engine powering both Chrysler 300 SRT8 and Jeep Grand Cherokee SRT8 - is also in the works, but no confirmation on the subject has been released so far.
