This is a moot point since the C7 was just introduced. For the Viper to be going against the 2013 ZR1 and for the ZR1 to be doing so well against the brand-new Viper, the C7 is all that More awesome!
Giles has mentioned that the New ACR will have 1500lbs of Down force. that's a 500lb Increase from the 2010 ACR, that means its gonna have some massive Power update for a top trim Viper to have that amount of downforce
What everyone is failing to realize, the Vipers that's being Driving and Tested by Magazines are Pre-Production Vipers, Thats why they dont have the Production Seats giles mentioned on Twitter Viper #001 is the Metallic Red GTS Viper ( the one thats was built to giving to the person who won the Auction on Barrett Jackson) and the 50+ Inaugural GTS Viper (blue /w white strips) will be the 1st Production Vipers. . Both versions just started production last week.
I love the new Viper, but seriously, ZR1's been out for 5 years now and this Viper's brand new..
Oh and I just noticed that the headlights on the Viper are part of the hood... wtf?

The one thing that I would say that I find impressive is even though the ZR1 Corvette is softer then the Viper it still managed a better lap time.
Though I would expect the ACR Viper with its down force and adjusting the suspension for the track should easily beat the ZR1's lap time (as it should in that configuration).
I will admit that this victory was much to my chagrin because I actually thought the Viper should be able to match or beat the outgoing C6 ZR1.
I would be more than glad to have either or both in my garage. Beautiful beautiful cars.
Remember all things being equal means that as you scale up the bore the stroke should be too, and the intake runners, paths, exhaust etc. Which should equal that same port velocity between the two engines, but the larger one will move more air because it has more volume. That means more power.
But even if it wasn't all equal the larger engine can use smaller runners and move more air from higher air velocity. Of course that goes into design and all things being equal get's tossed.
But from some real world examples we have the 4.8L, 5.3L and 6.2L engines -all from the exact same architecture- where they grow in power as the engine grows in displacement. Same can be said of the Ecotec 1.4T to 1.6T to 2.0T, and the Ecotec 2.2L to 2.4L. Lets look at the HFV6's 2.8L to 3.0L to 3.6L all the exact same result. Growth in power with a growth in displacement.
The thing that doesn't follow suit is fuel economy. The 5.3L is bigger and more powerful but gets better gas mileage than the 4.8L (even without AFM).
There are many more examples, but the fact does remain, there is no replacement for displacement. Boost an engine, then boost the bigger one the same amount and the bigger one see's a greater horsepower gain, every, single, time.
A GT500 is a 5.8L running 14psi of boost takes it to a 11.32L (assuming a 100% VE). The LSA from the Camaro runs 9psi on a 6.2L which equals a 9.99L (assuming 100% VE).
