The 580 HP supercharged ZL1 Camaro is $55k and the 505 HP 7.0L Z/28 Camaro is $72k.
I think the Z/28 is faster at turning than the ZL1 though with a 7:37 Nurburgring time (semi wet track).
I don't know how well it will turn but the Challenger will make more power than even the Viper. I think cars in NASCAR are only 800-850 HP @ 3400 lbs so at this rate even street legal sports cars are catching up.

It's more fun to build your own mega power engine.

The Author saying that the Shelby cobra was the biggest ever, but that is not a Factory Production car, a factory production car is just what it say's, no tweaking after production right from the factory, Dodge claims the Hellcat is the most ever, & it's the most horsepower ever from the original manufacturer, & that is correct, nobody else in the USA manufacturers has ever produced that much horsepower from factory, John Hennessy reworked Vipers & Corvettes & has got incredible horsepower, but that isn't what Dodge is talking about. (FACTORY)

Wow. That's half a megawatt. In all seriousness - you could literally power your entire neighbourhood's electricity usage if you hooked this baby up to a genny in your garage while not driving...

@ christopher The engine doesn't have much operating time at that output level. Running at 700 hp it would probably eat itself within an hour. That does not mean that an engine of the same power and displacement could not be built to continuously operate at 700 hp.

Great, I just found out Dodge uses plastic impellers on there water pumps. what a joke. who else is doing this ?

Go Ralph Go!!!
Fantastiche!!!
You are the masterpiece!
And You Know CARS!

At the end of the day....Who cares? 700 bhp on a car that doesn't steer worth a damn at 30 mph.

Plastic impellers? Well, lets see the porsche I sold had them, as well as many other plastic water pipes. My BMW had plastic water impellers, which I replaced with a metal equipped water pump, though not before I lost the head gasket. Mercedes and Volkswagen also have nothing but plastic.
BMW and porsche expect you to replace the entire cooling system at around 45,000. You read that correctly. Replace the plastic radiator, water pump, auxiliary electric water-pump, all the hoses. Even if you do your own work, it is neither inexpensive or fun. Interestingly enough my 62 Impala SS still works with the original radiator. And is still faster in the quarter than an M-5.

I love reading comments on these types of posts. Shows how uneducated morons out there that are bashing a car maker for putting plastic impeller on water pump. Thanks to Steveraxx for putting people in their place with a fun filled factual filled posting about plastic impellers.
