Prefix previews their SRT Viper Convertible
Official announcement scheduled for Monday
Prefix has released the first details about their upcoming Medusa.
Based on the SRT Viper, the Medusa is a stylish convertible that looks like it came straight from the factory. Details are limited but we can see a retractable soft top and a modified rear end that has been specially designed to accommodate it.
The Medusa was recently unveiled at the Viper Open House and an official announcement is scheduled for Monday. In the meantime, we'll remind you the Viper is powered by an 8.4-liter V10 engine that produces 640 bhp (477 kW) and 600 lb-ft (814 Nm) of torque. It is connected to a six-speed manual transmission which enables the coupe to accelerate from 0-60 mph in the "low 3-second range" and hit a top speed of 206 mph (331 km/h).

Dodge Viper's V10 Engine Gets 5 More Horsepower for 2015 MY
A power increase is never bad news, but when it comes to high-performance sports cars, one may expect more than just…5 horsepower. That’s what buyers of the 2015 Dodge Viper are going to get, with the 8.4-liter V10 engine to produce 645hp instead of the current output of 640 hp.
The news about the extra power comes from Road & Track through the SAE J1349 certification database, which is an opt-in test for manufacturers to get engine output certified. Chrysler, Ford and GM are currently the only automakers to use the test. While output increases by 5 horsepower, torque remains the same at 600 lb-ft (812 Nm).
We don’t know how (or rather if) the power increase will change the Viper’s performance, but one thing is certain: Dodge’s flagship model won’t be as powerful as the 650hp Chevrolet Corvette Z06. Still, it may prove to be lighter, as its power-to-weight ratio will be improved by 0.8 percent for 2015.
The SAE certification doesn’t say how Dodge got the extra power from the engine, but the safest bet is improved breathing and/or ECU.

This is a natural aspirated engine so it's harder (afaik) to squeeze out extra performance from it........compared to force induction systems.

I believe its being held in check. Remember Fiat own the company, and it already approaches Ferrari territory in power. It could make 700hp if they let it. Emissions and that stuff could be an issue as well?

Part of the problem though is the Viper's Italian cousin the F12 with it's 731hp 6.3L V12. Ferrari wouldn't be happy about Dodge uncorking the 8.4L.

You're right, though, that it does not sell in large numbers, especially compared to its arch-rival Corvette.

But one thing is interesting, though........(and you're right....there may be an exception). The factory does offer a Track Experience for Viper and other SRT owners who desire it....presumably that would include standing behind their vehicles if they break down or fail during that event. .

Which means that even a future ACR version would be restricted so that it won't surpass the F12 Berlinetta.

Dodge Viper to gain a supercharged V10 engine?
Could produce up to 800 bhp (596 kW)
The Dodge Viper hasn't been flying off dealer lots and the recent introduction of the Charger and Challenger SRT Hellcat could complicate things as they feature a supercharged 6.2-liter V8 engine that develops 707 bhp (527 kW) and 650 lb-ft (880Nm) of torque.
Since both models are more powerful than the Viper, engineers are reportedly looking at ways to put the Viper back on top. While nothing is official, Allpar is reporting the company has begun working on a supercharged 8.4-liter V10 engine.
The publication believes the supercharger could enable the engine to produce up to 800 bhp (596 kW). If this is correct, it would be significantly more powerful than the current engine that develops 640 bhp (477 kW).
