But Bushido what you just said means it got a bigger hp gain than a Viper. A stock Z06 has 505 hp and 470 trq. So it got a 66 hp gain and 64 trq. But thats at the wheels. Which is still more than the viper.

It might not have AS much hp as a viper but, it is lighter. So for the amount of hp it just made is equivalent to the 604 hp the viper makes.

Remember the 08 Viper beats the Z06 by small margins. When both cars tested by numerous car magazines. Viper always beat it to 60 by .2-.3 seconds 1/4 mile by .1-.3 seconds. On the lap course by 1.2 seconds.

Plus the Z06 does handle much better than a viper, it doesn't catch you unexpectedly. Doesn't require nerves of steel and yanking the steering wheel left and right just to get the rear end str8. The Z06 is more friendly and easier to be pushed to its limits.

So in total it is a very close race between the 2 and does boil down to the driver. So if a header/exhaust/ECU/ and or intake will kill an 08 viper.

Now compared to the ZR1, the viper is faster to 150 mph, which is funny. I don't know about 180, 190 or even 200 mph. I think the ZR1 does beat it there.

But if you really look at it without bias. The Z06 is really close to the Viper and ZR1. As far as tuning FOR NOW. The Z06 is your best bet, since everything for an 08 viper is so damn expensive and not many people have tested stuff on them yet, and the ZR1 is close to its limits, pushing it any farther will cause reliability problems. Like blowing a head gasket.

You have no damned idea what you are talking about.

Z06 vs. headers, intake, ect vs. bone stock 08. This was one of the members on the alley and maybe here too.

Um, The Z06 was making 487 hp, my friends dynos near 520 hp, which is lower than the 08 stock viper

His Z06 out right destroyed the 08 viper from 65 pull and some where in 120-140 pull.

Im not talking down on the viper. Its just that, the 08 viper isnt THAT MUCH BETTER, its just better. Remember it just barley beats an 07 C6 Z06. Now if you tune it...it wont be able to or it will be just as fast.

Ill ask my friend if he has any videos of him racing against 08s. Ill post them up if he does.

Wow, a Z06 that probably has headers, intake, tune, and cam can beat a bone stock Viper. You do realize Hennessey got 616 RWHP out of headers/exhaust on a stock Viper? 546-616 RWHP. And don't bullshit and start talking about porting the LS7 heads. Call Katech and see what difference that makes. That would be 5 HP. Almost all gain from messing with the heads on the LS7 is from milling them and boosting the compression. LS7 engines love compression. So, when you are done and have done heads, intake, cam, headers, and tune, you make about 560-570 RWHP. That's great, but an 08 Viper hits that with a catback exhaust. Do headers on top of that and you will run right there with a fully gone-through LS7.

[MarshallTK]

Yea, i know. Im just saying. That the Z06 is no push over, especially when it gets close to how much hp a viper throws down.

It boils down to the driver honestly. I mean ive seen some Viper drivers that cant handle the power, not meaning they're bad, but that they cant control the wheel spin. You cant just sit in a viper and slam on the gas pedal like a Z06.

Btw, i really dont trust hennessey and his tuning. That can be bs. I know someone on this forum, who sent in his viper to come out as a 1000 hp venom, in stead it dynoed 500 hp. :/

So if you really wanna send your viper to get the 616 rwhp. Good luck :P.

Hennessey's headers are plenty good. His fabricator is quite skilled, he uses quality collectors and his dyno produces pretty accurate numbers. A few people have dyno'd at other shops with his headers and gotten over 600 RWHP. Nobody is hating on the Z06...its just not going to beat a Viper all other things being equal. The Zr1 on the other hand is very close. Totally a drivers race. I bet you could race on 3 different days with different weather ect and get different outcomes.

[MarshallTK]

Of course, only consistent place is Antarctica, its always around the same temp/cold.

True, i mean its close tho, The ZR1 and 08 Viper make the Z06 a everyday car. But dont be fooled. But i understand where your coming from and you are right, But it can easily change.

The ZR1 may of lost to a 0-150 mph drag race, 17.01 vs 16.4. But i think it might accelerate to 200 mph faster, due to the supercharger.

I thought C6 Zo6's were at 505HP on the motor? Not the wheels.

[MarshallTK]

Yea it does make 505 hp and 470 torque at the motor.

What i was talking about was that bushido said a tuned z06 makes 571rwhp and 534, which compared to the actual amount of hp and torque a z06 makes is alot more.

So it gained more than 66 hp like 148 hp and 114 torque. Which is alot more than what a viper gains from the same mods.

But with that much hp/torque a z06 can beat a viper in drag, stock viper.

[The Former PFR]

This is what it takes Lingenfelter to achieve 566 RWHP:

Package Includes:

- American Racing Headers
- Engine removal & removal of intake manifold, cylinder heads, camshaft
- Lingenfelter CNC porting & polishing of cylinder heads for optimal flow
- Lingenfelter multi-angle valve job & surfacing for 11.5:1 compression
- Ferrea high performance dual valve springs, titanium retainers & valve locks
- Lingenfelter ZO6 GT21 camshaft by Competition Cams
- Lingenfelter High Flow C6 ZO6 Air Induction & 4" diameter Lingenfelter Mass Air Sensor
- Port Matched LS7 intake manifold
- Ported and polished LS7 throttle body
- Higher capacity LS7 fuel injectors
- GM Head gaskets & head bolts
- 160 degree thermostat

This is a gain of 113 RWHP. A Viper picks up 70 RWHP just from headers/exhaust. What are you talking about the Z06 picking up more from mods? The best headers on the market from LG pick up 56 RWHP. BTW, the above package is about 13k bucks when you account for the headers they want you to have before you come to them.

Uh, you're talking to people that have owned or own ZO6's currently and have been playing the LS Game for awhile.

I'm telling you, I had to do a LG Stage V Heads and Cam on my 08 ZO6 to try and get up to my ACR stock!

Viper is the better platform.

What car do you drive? You have a C6 Z06? What kind of power does it put down?

.

Dont forget tuned with ported heads and after market rockers, cam etc. That said,I cant imagine how much more horsepower an 08 Viper will gain from ported heads, and a hotter cam.. With just boltons its already making over 600 rwhp..

[MarshallTK]

No i dont have a z06, my friend from Arkansas does.

Hennessey

Camshaft Upgrade
Upgraded Valve Springs
Crank Bolt Replacement
Long Tube Headers with High Flow Catalysts
High Flow Air Induction System
180 Degree Thermostat Upgrade
Reprogrammed Engine Management Computer
All Necessary Fluids & Gaskets

rformance:
0 - 60 mph: 3.3 sec.
1/4 Mile: 11.2 @ 132 mph
Top Speed: 210 mph

620 hp @ 6,500 rpm
568 lb-ft Torque @ 4,900 rpm

Same amount of HP and torque as an 08, almost. But its faster.
Infact its faster than the hennessey tuned viper, which has 678hp and 645lbs of torque.

What do you say to that? Corvette can beat a Viper with the same amount of hp man, its 300 lbs lighter. And more aerodynamic.

Marshall, Hennessey's 08 Viper Vert ran a 10.77 at 132 mph and thats just with headers and exhaust..

[The Former PFR]

Marshall, just stop and quit magazine/website racing. Hell, you're not even doing it right, claiming the Z06 is a more benign handling car than the 08 Viper. That's absolutely backwards. The Z06 has been continuously criticized for its feel around the race track, whereas the Viper has been lauded continually.

With some denistry work on the heads and intake I'm told around 40 to 50 HP gain.

I'm also told that w/the VVT system we can't put to much more compression because of the ECU.
Does not matter if you have the Mopar ECU either.

[MarshallTK]

10.77 @ 132 with DRAG RADIALS. Add some to the Z06 and it will be around the same time if not faster.

Guys look, i love the viper just as much as the next guy. But you cant live in a fantasy world. Z06 is right up there. Sh1t for all i know, its been faster and better than the viper since 2005. Ever since the C6 Z06 came out, its put it to shame.

Yes the viper is lauded on the track, but if you push the throttle in the turn you will spin out. If you push on the throttle when ur out of the turn you will spin out. ITS A CONSTANT BATTLE WITH THE VIPER!!!! But no doubt it is fast, no doubt it is a car that you would choose over a Bugatti or any other car because of how its personality is, its looks, the roar of the V10 when you near redline. But not everyone can drive it. Sure you give me the Viper and i run a 10.00002 @ 150 mph, Give it to the next guy and he runs a 19.355555 @ 90 mph.

But the 08 has come in and told people things are different, but not that different. Yes it makes even more hp than before with the same mods, sh1t it makes more hp than those lambos wtih v12s, thats 12 cylinders! Its cornering ability is better than any production car out there for its price. Its nearly a perfect car.....IN THE RIGHT HANDS!

And yes Bushido it was headers, exhaust, Catalytic converter, and air filter.
Giving it 78 hp 85 torque. Dynoing at 616 hp from 678. Which is a 62 hp loss.

Performance:
0 - 60 mph: 3.3 sec.
0 - 150 mph: 15.5 sec. (stock 2008 Viper = 17.0 sec.)
1/4 mile (street): 11.32 @ 131 mph (factory Michelin PS2 tires)
1/4 mile (track): 10.77 @ 132 mph (BFG 345/18 drag radial tires)
Top Speed: 211 mph (estimated for the hardtop coupe)


Z06 is a calm car. Like a quiet person at work, but then all of a sudden comes in one day and shoots everyone. The Viper does that everyday lol.

[Sadistic]

You are dead wrong when it comes to handling. The Z06 has a far less rigid frame and dated suspension setup in comparison to a Viper. At the edge of cornering, a Z06 is wacky and imprecise. It suffers from oversteer, poor suspension and a twitchy, relatively weak frame. The Viper has oversteer in the hands of a newb but not with a driver who has any skill. A Viper's handling is much more predictable and the power comes on smoothly, which also helps.

As far as hop up potential goes, the Viper still has the upper hand just for the fact that it has more displacement. '06 and earlier Vipers obviously have the most potential via turbos etc.

The ZR1 seems to have more hop up potential than either a Gen IV or Z06, dipping into the very low 10's with relative ease.

Thats true thats why all the race corvettes such as the C6Rs all use the regular C6 steel frame. Not to mention swapping out the leaf springs to coilovers..

[torquemonster]

blame Daimler Benz. They screwed Bob Lutz out of a job, and when he was taken up by GM he vowed to beat Chrysler at their own game by making the Vette beat the Viper.

Bean counters pulled the ZO6 down to a close call, but if you factor in performance per dollar - he did it stock for stock until the 08 Viper came out. That required the ZR1 but at a higher price, putting a Vette higher than a Viper in price for the first time.

They're all good cars for the markets they serve... at least until something falls off on the Vette. GM is not great at assembly.
