All of you who think SRT doesn't have the budget to compete, let's not overstate the task...aggressive aero package, lose more weight (aluminum frame?), dry sump, add PSC or Trofeo R tires, 7 speed or DCT, and Brembo carbon ceramic rotors on the ACR and it's done. That won't take a lot of R& D to accomplish. Ralph, build our Viper ACR!

you just built a $200k viper.

I came away with the same exact impression on all points... Although maybe they just want to sell the remaining new ZR1's sitting around at dealers...

Everyone should watch the two videos posted. In each Vett engineers state that they were trying to "approach" the performance of the ZR1. If their comments were scripted and the words chosen carefully, I think we need to wait for the testing before assuming that this car equals or betters the performance of the ZR1. Also, they state that the new blower is smaller by volume but rotates at a much higher speed. That may not be good for modification. A pulley change may not be possible. There are limits to how fast a spin can be tolerated. Engineers out there please post your thoughts. I was under the impression that more volume with a 6.2 liter V8 was better.

I still can't stand the way it looks the C7, even with the Z06, i think it looks awful. That's just a subjevtive opinion, still, i'm afraid that this new corvette will **** SRT and GTS Viper's at straightline performance(Better gearbox, a little bit more Torque,lighter???) and also at the track :/.
In terms of price, Viper is also loosing.
Imo, SRT should take this as an oportunity to built an astonishing ACR to beat Z06 and be able to face a possible 2016 ZR1, at a reasonable price of course.

No new motor needed. Adding 40-60hp to the V10 could be done off the top of any SRT techs head and in less than a days work, including tuning.

If it was that easy they would have done it on the Gen V and got everybody to **** about the "only" 640 HP.
680-700 HP has a nice ring to it if you believe HP sells cars.

The blower on the new Z06 will seriously limit modability (unless you want to replace the entire unit). Car also already has headers... They have wrung most of the power out of the new Z06... Not a lot of room for aftermarket there... I'm disappointed [and I am a Die Hard Corvette enthusiast].

Right and that doesn't leave anything on the table for anything else for them to build.

So why do you guys think a ZR1 is coming? It's not. This is it. GM will produce a few variants as far as exterior packages but the Z06 is it.

My sources at GM would tell you that you are wrong. They have been testing twin-turbo V8 C7 mules. The same twin-turbo V8 will also come in the next CTS-V. If you think that engine was developed solely for the Cadillac, you would be incorrect.

I think it's the complete opposite. Engineers always leave at least 20% for reliability purposes. The engine is already setup with perfect 10:1 compression, titanium rods, and forged everything. You don't think that blower can't be pullied and tuned at least another 15%? That would be another 75 to 90HP bringing that monster to 700+ HP for under a grand in mods. The fact that it comes with headers makes it even more ready, IT ALREADY IS SETUP FOR MORE POWER. That V8 was designed to be a modding platform.

HERE'S WHAT NEEDS TO BE DONE TO REALISTICALLY COMPETE ON AN SRT ENGINEER'S BUDGET....
Redoing the Viper's frame in aluminum is not the way to go. We already have a winning platform and it doesn't need to be re-certified. The whole body is already carbon fiber, so other than removing sound deadening junk and getting racing seats, there is nothing left to reasonably cut the weight by more than 100lbs. I think the cheapest thing SRT could do is simply go for more power, but here's how: The simplest solution would be to sell a $100 track key for the ACR that turns on a gas guzzling tune that kicks the HP to 700+. Problem solved. Doesn't need to be re-certified because it's not a street legal tune. The engine can be rated for say 650 on the street and advertised that way. The track key will be the underground secret weapon and of course the buyers will all know about it. No re-cert, no redesign, no hassle... just blunt force trauma.

That's an interesting tidbit, Tony. Here's how I think the script plays out: C7 Z06 narrowly beats TA on track. TA gets Trofeo R tires and narrowly re-takes the crown. ACR comes out and crushes all comers. Chevy answers with ZR1, but I'm not sure who will win that gunfight. Good time to be a car guy! This era will be remembered as the best in automotive history.

I heard this also. They would market the ZR1 as the halo and take it up to the 150k range. It would be plusher inside with more sound isolation materials and systems. It would be faster than the Z06 but also have more premium materials as expected in the higher segment. Basically Z06 = SRT and ZR1 = GTS.

Who knows, a lot can change in 1 - 2 years.

As much as I hate (As a Viper purist) to say it the Viper needs a paddle shift option to compete in the near future. Whether the new transmussion is bought from another manufacturer or designed in house that's what it needs. That coupled with sticky tires and an ACR package would put the new Z06 back in its place.

All the Viper needs is a blower option, the motor is strong it can take it , an easy 750hp with a blower. But still its funny, who would have thought just even 5 years ago that the viper would have 640 hp which is sic, but Mustangs with under rated 662 hp and base corvettes 450 or more, this is a great time for car guys, I love it if I was rich I would have one of everything:D

This hasn't ever been my experience. I've been buying factory supercharged cars since 2003 and easily & cheaply modding them to enormous gains. I've modded NA cars to be FI and know the pain of pulling the heads & o-ringing, etc., etc. For a factory blown car it's been cake for me. Most recent example, 2014 GT500, made 603rwhp stock with 500 mis on the clock, $1600 in mods and 3 hrs on a Sat morning, revisit to dyno and a conservative street tune putting out 712rwhp. And for my purposes, street play, drag events and open tracking a few times a year - 700rwhp is more than enough. I will be amazed if this new Z isn't just as easy to mod, vettes have mods available amost before the next gen is sold, a big selling point for us guys who like to tinker. The aftermarket is proabably alrady drooling over mod ideas for this new puppy. I'm NOT a vette fan, never have been, respect the performance big time, but have hated the looks ... this is all changing for me, and I'm scared. ;-)

Five yrs ago was 2009, the Viper had 600hp, so yea no one thought it'd have only 640hp today, most thought the number would be 700hp. I'm not beating the dead horse on this, I'm fine with 640, I do wish we had mods, but yea, I think if you went back to 2009 and said the next gen would get only a 40hp bump no one would believe it.

I hope you're prepared to see the TA record destroyed by a car costing at least $40K less. I love my Viper, but I have to say I'm really disappointed with the lack of ceramic brakes, and the cost of the new GTS. I still don't understand how or why the GTS cost so much and you still get inferior brakes.

Yawn, more of the same.

I wonder why some of you even post on Viper forums.

Not me, I'd be happy, and itsn't that all that really matters?

lol

Look below you, if the Viper offered ceramic brakes, someone would find something else to complain about.

People complain of the Price of the viper at the cost of an optioned out GTS still, but in reality you can find one for well under $100k

Just boring yammering by people who are just into complaining.

If you think the Viper needs ceramic brakes, well go buy them. Complaining you won't buy one because it doesn't have "X" part you can buy in the aftermarket is just pointless jibber jabber. Shows you aren't really in the market.

For those of you who have not done so, I recommend that you see if you can get the opportunity to drive a production Gen V that is fully broken in and take it through the gears. The car is fast - very fast. Fast enough to cause a brain stem fear alert that has to be overridden. I think that many owners will not feel comfortable utilizing the full capabilities of the Gen V Viper and it is perfectly understandable.

The 2015 Z06, which is not in production yet, will not walk the TA on a road course. Their own engineers stated that it "approaches" the ZR1 performance and a preproduction TA with lesser tires beat the ZR1 at Leguna Seca. A production TA with the same tires that the ZR1 used in the test would considerably improve that time.

I like the looks of the Z51 variant Vette. The Z06 without full aero looks very similar.

Brand wars are a great thing!

It is that easy to make that power increase, ask any Viper tuner here. The reason they have not will be political. I'd be amazed if SRT have not privately seen 700hp on a development engine long ago. Long tube headers, higher flow cats and exhaust, cam, retune, done. All that is not difficult on a low production legal but track ready car.

Dman, I know what you mean, its so easy to mod factory blowen motors, esp GT 500, pully swap and a tune easy 100 or more hp gain, great times for car guys, the new stuff kills anything I had as a kid, when I look back the cars were slow, as fast as honda civics today.:D I guess I mean 10 years ago who would have thought the Viper would have 640, meaning thats alot, all the cars now have alot, I lose track of time.Everything has come a long way, and its good for all, what ever brand you like. I will say it again the Viper is king In my book.

What about passing emissions after your proposed improvements? That was a huge obstacle on the Gen V development. It's very easy to make big power, but hard to make it burn clean. I don't believe they could do longtubes because they relocate the cats, and high flow cats that last long enough may also be a challenge. And I would imagine the cam has already been tweaked as much as they could without failing emissions requirements. I'm no expert and hope I'm wrong, but I think making big power in this smog-legislated day and age is not easy.

It's my impression that Ralph's goal for the car is for it to be world class on the track, and exclusive and engaging to drive everywhere. He would know that a more powerful engine isn't the answer to keeping it a world class performer, nor that CCB's and a DCT are necessary to make it the fastest production car on the planet around a bench mark track. Did he solicit advice from forum posters about how to achieve that goal, or give any indication that he's now interested in advice the day after a Z06 is unveiled? And honestly, as far as sales go, he knows the car is good from the feedback Gen V owners are giving, and when even ACR owners are embracing the car it must be pretty easy to filter out the noise from everybody else. Can never please everybody...but he can at least please those that share his same goals.

I agree. Many race cars still dominate at the track on steel rotors. The best way to cure yourself of this carbon ceramic brake obsession is to wear a set out and have to replace them. The latest new thing in brakes is silicon alloy like the P1. Ceramic brakes are lighter than steel and handle more heat, but do not last as long and won't stop any quicker. If pads are not fading now on steel rotors, what is the gain? A fraction less unsprung weight is about it - assuming the potential weight saving is actually there.

I'm not privy to the law on this or whether there may even be a concession available for a low production run. However adding a fuel heating bypass under part load will clean up emissions significantly (on a 5 gas analyzer I've seen zero readings doing this on an SRT10 Ram - obviously not zero in a lab but too low for a 5 gas machine to pick up so pretty good compared to factory setting). Cold fuel could be restored as throttle is opened. Also with VVT the smaller cam setting could remain stock - keeping the certification. The larger cam events would only come in "above legal highway speeds" so should not require certification. All the gains would be on the higher cam setting where the tune would also change leaving the engine stock under 4000rpm. Just ideas, SRT will have a lot more. This is not hard.

I am a car guy and I also am very happy to see two American cars with such great performance, Both the Viper and Z06 keep topping each other
this makes for good competition and better for us the consumer.
