I don't know, can the Viper hit 230?

The Veyron seems like it will do better and I think Vipers can only go about 200mph. The Veyron can go somewhere past 250mph, so I take the Veyron.

Even if the viper can go that fast I think I would rather go that fast in the veyron. From what I read its very stable at high speeds 200+. Vipers are known for just being powerful with no electronic assists or anything. The viper is likely a better track car but the veyron was made to go to 253 MPH.

Was it just a rumor or are those Hennessey numbers being a little "stretched" in order to make the Viper seem better? I thought I remember a thread on here about that.

Anyway, I'd rather have the Veyron to go top speed in. I personally don't think the Viper could go past 220.

i doubt vipers can hit 230, even with the hennessey package. Even 200 would be a strech.

Ain't the top speed for a stock Viper 190mph? Thats what I heard.

Yeah that's what has been put in MT, C&D, ect.

I've heard stories though, don't know how true they are, about people racing Vipers and once they get around 180 they fall flat. They will still reach 190 but it's a struggle after 175-180.

Veryon. It's made to be more aerodynamic at 200+ mph. So when the Viper is getting air drag at 200mph, the Veryon, locked in the "top speed" suspension setting, is literally being 'sucked' to the ground all the way up to 250mph.

the veyron was just designed from the start to go that fast, the viper wasent, and i dont think theres much you can do to it to make it cruise smoothly at 200+

aero def plays a big roll

but also, the viper is a whole lot lighter than the veryon with the same amount of power

The Viper is lighter by like 750-1000 Lbs. right?

exactly!!

732 to be exact

i doubt vipers can hit 230, even with the hennessey package. Even 200 would be a strech.

i think if a stock viper can go over 180...then one with double the horsepower shouldn't have much trouble going well past 200...heck, it can hit over 200 in just a standing mile run.

what it comes down to is aerodynamics. it took engineers years to make the veyron stable at speeds of over 200mph. i can't imagine imagine how dangerous driving the viper becomes at those speeds since it wasn't engineered with that in mind.

so on safety and sanity alone, i'm going to go with the veyron

i just checked my stats, and the hennessey viper did the standing mile 25.6 seconds and hit 210mph...and that was with a 15mph headwind and in the convertable! just imagine what the more aerodynamic coupe could do without the headwind

the sledghammer didnt have years and years of aero work, just a c4 vette with 880hp that ran 254mph

though the veryon is more stable, thats not the comparison, its wich you think is faster from 60 to 230mph

both the same amount of power,

veryon is more areo
viper is 732lbs lighter

I still say the Buggati Veyron.

well, in that case. i would still go with the veyron. obviously i'm just guessing, but i think that when you start talking about 200mph and over, aerodynamics starting playing a much larger role than weight. even a small aero advantage would more than make up for the weight difference at those speeds.

wind resistance goes up exponentially and i recall correctly (from having worked with wind generators), it goes up to the power of 3 (although it might just be to the power 2..) at each "step" so yes, at high speeds, even the slightest numerical advantage in this area, produces massive advatanges in results.

i rest my case

but don't quote me on that....
i have a vague memory of the basic equation and it was exponential.
i'd have to go and dig up my papers to be sure but bear in mind that it was a wind generator and not cars.
the principles and mechanics aren't going to be directly applicable but the general gist should
i.e it makes a great difference.
it's why a CD of 0.31 and 0.33 makes such a difference even though the numerical difference in just 0.2

the exact mathematical equations aren't what's important. it's just the basic idea that matters. of the two things that we're comparing for high speed acceleration, weight vs. aerodynamics, aerodynamics plays a significantly bigger role.

i agree, lets say the viper will start having problems at 205mph. lets not forget that the viper has over 700lbs less wieght to get a(possibly) good lead on the veryon from 60 to 205mph
thats a huge weight difference HUGE!!! now from 205 to 230, that would be in the veryons favor but from 60 to 205, thats alot of time to get a certain lead to even things out at the top

well all those years and years of aero work and all they can come up with is 0.35 cd??

hell my vr4 has a drag co of 0.33 cd

but as stated above, the veryon, while not the best it still has a better drag then the viper wich has a drag co of 0.39 cd

then again, that wind resistance doesn't just suddenly kick in at x mph, it's always present.
just found a reference to another speed timing figure for the veyron:
0-250mph in 55 secs.
0-188 in 16.7

anyone know how this compares to the viper?

Veyron: aero is more important that weight as has been said.
A veyron costs 9 mil to make...
So it's no surprise.
However on a track the story might be different ;)

I know it isn't between a McLaren F1 and a Veyron but I think this settles it...

"In a drag race [between a Veyron and a McLaren F1] you could let the McLaren get to 120mph before setting off in the Veyron. And you [the Veyron] would still get to 200mph first." ~Jeremy Clarkson

whos to say a car with just as much hp and 730lbs less wight couldnt do the same??

Would a GT Mustang be able to do all of this if it had 1000 hp? No. It wasn't designed for this.

The Viper was not made to try to set the world speed challenge.

A Mclaren F1 has 627 HP that viper has 1000hp...
A viper has shit aerodynamics but is an 9 second car where as the M F1 runs a mid 11.

niether was the c4 corvette, but it did it with 880hp

i'd probably pick the veyron, it was made to handle those speeds

that i agree with, it is def made to HANDLE those speeds. weight helps a hell of alot

that i agree with, it is def made to HANDLE those speeds. weight helps a hell of alot

yes it does...by alot. most cars made for speeds usually weigh a little more to prevent lift.

ya know one thing that i have thought about with this particular comparison is the fact that AWD is known to take away from top speed due to significant drivetrain loss coming into play.

this makes me wonder which car could actually reach a higher top speed. we probably all know that any of us would rather place your life in the hands of the Veyron due to its long time engineering to be a safe as possible at those speeds but that doesnt mean the Viper could not out peg it on the salt flats. it makes me wonder at what speed, outside weather being a controlled variable, the viper will fly at.

there is also alot more to aerodynamics than drag coefficience. when talking those speeds the amount of downforce created is just a big of piece of information as drag coefficience.

i love you k3, you always make the conversation interesting

you see exactly were i'm coming from, its something i'd pay money to see
viper and veyron from 60mph to 220mph

it be interesting to see.

i've also learned about the awd drivetrain loss bieng a misconception

whp is whp, no matter how its bieng used. bhp would be diff, awd usaully has a lower whp from bhp than a rwd or a fwd

but whp is whp, its all bieng delivered.

so the awd isnt doing any slowing down as of what i know.
we've had this discussion between me, redneck,tatt and some others.

i personally think that stabalism and aero is more important once you get so high in speed. but weight is not completly counted out, especially 735lbs

the more a car weighs, the more power it takes to keep it going at those speeds. which would make one think that the viper would have the advantage in more than one reason at higher speeds.

but then again, the veyron also has a couple advantages itself.

Viper Advantages:
both cars produce similar power, number wise. this is why i brought up the AWD factor. if a car with AWD produces 1000fhp and a RWD car produces 1000fhp, the RWD car is going to have the advantage once at speed beings it will be creating more power at the wheels. this would give the Viper the advantage once breaking loose doesnt become an issue. the viper also weighs significantly less so getting the Viper moving faster would be easier even if whp was the same.

Veyron Advantages:
now just because the Viper is lighter and can, in laments terms, keeps its speed better and the lighter weight making it easier to create more speed, doesnt mean that this is a full advantage. being of lighter weight, would mean it will take more force to get it to stick to the road and not going airborne. this is where the veyron comes into play, we know that the veyron can maintain speed and reach these types of speed without the worry of lift due to its weight and aerodynamics. how big of a role do these play, is the question? also, lets talk gearing...i believe the Veyron has a 7 speed transmission in it compared to the 6 speed Viper. at what speed will the Viper's gearing run out? i would assume that the Veyron's gearing would be better suited for top speed beings it's design has top speed in mind.

my honest opinion is that the Viper out matches the Veyron in top-speed if, and only if, it can stay on the ground at those speeds and its gearing does not run out. if it can stay on the ground at 250mph+ and it can even get to those speeds with its gearing, i would say that the Viper will man handle the Veyron up top.

the extra weight will be more of a burden on the takeoff. once you get all that weight moving you get some nice momentum going. the veyrons awd system takes care of launches and its aero takes care of high speeds.
