Viper TA Vs HellCat Vs C7 Z06 Dyno Results Inside.... Why it is a drivers race
Yesterday we had a client stop by with his 2015 Hellcat. After talking for a bit I offered to put the car on our chassis dyno to see the difference in power from our C7 Z06. Fortunately our client was agreeable to this and equally interested in the comparison......
Before I could get a chance to share the results another one of our clients stopped by this morning to show off his 2015 Viper TA... Of course after having a Hellcat on our dyno just one day ago I HAD to convince him to let us strap down the Viper. With only 50 miles on the odometer he caved to my persuasion lol!!!!
I can honestly say that I would have no issue owning a Hellcat or a Viper... Both are VERY cool cars in their own regard. The Hellcat is comfortable and roomy inside and has probably the best interior Dodge has ever offered.... The Viper has an amazingly menacing look and is more refined than Vipers of years past. All that being said, I cannot see myself giving up my C7 Z06 for either of the two. The C7Z (in my opinion) is the TOTAL package and is closer to exotic territory than either of its competitors.
On to the results....
The Hellcat we tested was equipped with the A8 Transmission. With only 1300 miles on the odometer it put down a stout 638RWHP/628RWTQ. According to Dodge 6th gear is 1:1 so at 6200RPM we were at 195mph
Next up was our clients 2015 Viper TA... With only 50 miles on the odometer and equipped with an M6 transmission this Viper put down 546RWHP/508RWTQ with its NA V10
Here are the results from our C7 Z06 with approximately 20 miles on the odometer. Our Z06 put down an impressive 585RWHP/611RWTQ
For comparison sake we took the time to overlay each vehicle with its competitor for a more direct comparison..
First up is our C7 Z06 Vs the 2015 Viper TA
Next up is the Hellcat Vs the Viper
Hellcat Vs C7Z
Here is a three way comparison......
And last, but not least here is our C7 Z06 as it sits right now with our VR800 Performance Package.... Unfortunately you cannot do this with the Hellcat
Something to consider when looking at these dyno results is CURB WEIGHT....
The VIPER TA might be down on power, BUT it is the lightest of the bunch coming in at 3364lbs....
While making the most overall RWHP the Hellcat comes in at a PORTLY 4439lbs
The C7 Z06 might be "the heaviest Corvette ever", but it is just slightly heavier than the Viper and weighs significantly less than the Hellcat coming in at 3524lbs
Factor in the variations in weight/horsepower and it is pretty straight forward to anyone with a racing background why these three cars are so competitive in a straight line...Unfortunately I do not believe the Hellcat or the Viper would come close to the C7 Z06 on a road course.....
As I said above, I 100% believe the C7 Z06 on top when it comes to fit/finish/comfort/overall performance. As you can see from the last dyno graph it is certainly not difficult to make big power with the new LT4 platform.
If replying, PLEASE keep the conversation clean. I posted this information in hopes it would shed some light on things, it is not my intention to "stir the pot"

So Corvettes that are a dime a dozen are more exotic than Vipers which you rarely see? Everyone is entitled to their opinion, but I completely disagree on that. Vipers are definitely rarer and more exotic.

We're well aware that the Hellcat probably couldn't keep up with the Z on a road course (assuming equal drivers), but you don't think the Viper would even come close? Come on now. You can think the Z would be faster, but saying that the Viper wouldn't even come close is just silly. Either way, it's going to be a close race. My personal opinion is that they would be very evenly matched around a road course (but if you have the new ACR package, it probably wouldn't be as close in favor of the Viper).

Fit and finish is very close between the Viper and C7. I agree that the Hellcat is definitely a step behind in that category. I prefer the Gen V interior to the C7Z, but I can totally understand how someone would think otherwise.
Thanks for the thorough testing and data you provided All three are awesome machines
I would disagree that Z06's are a dime a dozen even though more numbers than the Viper they will still not be seen much on the road. I think they are all great cars no need to justify owning any of them.

I agree that nobody needs to justify what they buy, but I didn't say Z06s, I said Corvettes. Aside from the fact that Vipers are rarer than the new Z06, an average person would have a hard time telling if the C7 (if they knew it was a C7) they were looking at was a Z51 or Z06. Hell, half of them don't even know what generation of car it is, they just know it's a Corvette. Look at the number of C7s on the road in comparison to the number of all Vipers ever made (not just gen V).
If you prefer the looks and feel of the Z then more power to you! It's a great car, but it is absolutely not more exotic than a Viper. This is coming from a C6 ZR1 owner. Less than 4,700 made ever, and the gen V Viper is more exotic than my car.

The thread isn't about Corvettes in general.. It is about the C7 Z06. I also believe you are confusing the term exotic with the term rare.... When I said the Z06 is more exotic I am referring to fit/finish/quality/interior/panel gaps etc.... After looking at both cars personally the Z06 does claim this title, although the 15 Viper TA is by far the best quality Viper Dodge has produced to date.

Alright, even if you want to talk about on the Z06 and not C7s in general, the Viper is still rarer. The point I was making is that when people say exotic, they mean something striking, and beautiful, and rare & unusual. Both the Z and Viper are striking and beautiful (although beauty is in the eye of the beholder), but the Viper is rarer. You are going to see something that looks like the C7Z way more often than the Viper.
We're going to have to agree to disagree then, because after having been in both cars, I think fit and finish & interior are very similar. But if fit and finish & build quality are the determining factors for an exotic car, then Mercedes takes it over both of them.
Lets keep the discussion about the Z06. I have both a Gen 5 Viper and a C7Z06 and last week sold my C7 Z51. The Z06 fit and finish is better than the GenV Viper. Im assuming the Z06 2lz finish will be similar to my Z51 3Lt finish. Lastly im a control freak and the Viper scares me while i was bored with the Z51. I hope the Z06 has the same feeling of control the Z51 did as it feels like its on rails and the Viper is a 60's muscle car like Lawdogg has said to me in pm's.

When my Z gets here ill report back.
You can't be serious with ( Fit and Finish ) better on the C7 Z06 than the Gen V Viper!! really??

Just look and the Michelin tires cracking thread here, poor guys Z06 has a fender gap a mile wide. No way the Vettes fit and finish nor paint can touch the Vipers quality. I also agree, Viper much more rare and exclusive!
Great comparisons Ron! Not sure if you covered this already, but is the Z06 an A8 or the M7? There was some speculation that the A8 will suffer a greater drivetrain loss than the latter, so it would be good to put this to rest.
Since both are supercharged OHV 6.2L V8s, the comparison between the LT4 and the Hellcat's Hemi is very interesting. While the low end torque output is quite similar and both peak near the 3500 RPM level, the Hellcat appears to breathe better beyond that as the torque falls off less rapidly. In fact, the Hellcat's power is still rising at the 6200 RPM point while the LT4 appears to have peaked. Both torque monsters without a doubt, but kudos to SRT for developing an engine that makes as much power at the wheels as the venerable LS9 did at the crank!

Yawn. Since you bring in 'average' drivers, try getting a couple to differentiate between a Gen III or IV and Gen V Viper. Hell between a gen I and gen V.
I know its early in the year, and you guys have probably not had the best weather in GA (guessing the storms that hit us in N. Dallas make their way to you a few days later)...
but have you had a chance to get your modded C7Z to the dragstrip yet? I'd like to know what kind of trap speed that things puts down!

Which is why I said look at C7 production numbers vs. ALL Viper production numbers. No matter how you slice it, the Viper is rarer. That has nothing to do with quality, it's just a fact. I know you hate me, but I don't deal in emotion like you do, I deal in facts about cars.

The Viper is rarer. End of story.
The opposite of love isn't hate, its indifference...did you say something?

I edited my post with the numbers. Care to address the topic at hand instead of acting like a child? Notice that in 2014 they made more C7s than Vipers have been made in the history of the car. Want to explain how the Corvette is rarer?
Oh crap Ron you done open a can of snakes here. We have many Viper faithful here that just can't accept which car is the best performance wise. Vipers paint I give it they have that by a mile. But we all know the Vette is the best performance car.
Im still shocked how low the viper came in on the dyno.
