Hennessey's Viper Venom 800R

Hennessey has taken the already menacing Dodge Viper and turned it into a 585 cubic inch (9.5L) monster, just in time for Halloween. You’d expect that this much displacement would deliver a mountain of torque, and thankfully the Venom 800R, as its known, doesn’t disappoint. Claimed figures read 810bhp and matching 810 ft-lbs of twist. To make that kind of power, engineers had to modify all the internals including forged pistons, ported heads, a big bore custom header and exhaust system, plus a cold air intake. The entire process takes the tuning house twelve weeks from start to finish.

Though the Venom 800R is naturally aspirated, it gives its 1000bhp cousin a run for its money. The 800R reaches 60mph from rest in 2.9 seconds and passes the quarter mile in 10.88 seconds at 136mph. Top speed is a claimed 230mph. Visual appeal comes in the form the full Viper SRT bodykit, which includes a new front bumper and rear spoiler. The Venom 800R will make its debut tomorrow at the DuPont stand at 10am at the SEMA Auto Show.
