Venom 1000 Viper Vs Veyron

[VetteDogs]

Stifling fast

Veyron still ain't pleasing to the eye but it does go like stink.

[Viper007]

Just read the article I will post up some specs for everyone. Take note that the Murcielago was the 580hp not the new LP640. Also, the Corvette only hand one run due to an unsolved oil leak the driver claimed he would have been capable of faster numbers with multiple runs. In addition, the SLR was not a 722. Specs are here: http://www.roadandtrack.com/assets/d...0_Data.pdf.pdf

Wow with all the data you can see how good the bugatti is. It spanks that Viper in everything that is even close to something you would experiance in the real world...

1/4 mile
1/2 mile

Still well ahead

3/4 mile still ahead and 1 mile by 0.1 sec.

It is also interesting to see that when the viper hits 200mph the Veyron is still ahead by 110ft.

The only thing the Viper spanks the Veyron on is the 100-200mph time and when is that going to happen in the real world?

And even when the viper gets ahead just alittle bit it starts to fall behind because the Veyron can go 253mph...

I would like to know if the Veyron was in handling mode during the 100-200mph tests because that would add alot of time compared to when it is in top speed mode.

How the arguement have changed to suit the Bugatti, now that the Bugatti has lost the 0-200 people now argue 1/4 etc. If thats the case then there are other cars out there capable of beating the bugatti. Surprise surprise one of the main contender is another ancient pushrod. This particular pushrod is again more effecient and effective than the Bugatti, using only two yup two turbos unlike the bugattis four turbos and two bolted on engines.

This arguement is pathetic. Both cars are useless, there.

Must be reffering to the S7 TT. The thing is with some of those carmakers is they always say they can beat the veyron and yet we never see any official figures.

Bar Top Speed the Ultima GTR720 has the Bugatti covered in all areas.......

Ultima Sports Ltd

The previous Ultima GTR640 also handed the Bugatti its European a$$. Not only was it using a more efficient push rod with only 6 odd litres and 8 cyl but was also able to reliably achieve 640hp in its naturally aspirated form.

[quattro_20v]

Forgot about that one, but that doesnt go 407km/h or 253 mp/h or does it?
Just looked at that page, the veyron is still pretty close to the ultima for such a heavyweight.

The Ultima is also European.

Still worst.comparison.ever.

With an American engine!!!!!!

A more efficient and effective pushrod!!!!

without bias, technically speaking (D)OHV is more complex and makes the cylinder head heavy but since there is less valvegear mass the valve timing can be more accurate and respond quicker, thus allowing less stiff valve springs. Pushrod has more metal between valves and camshaft and therefore require stiffer valve springs and a slightly poorer tolerance in valve control is found. Pushrod allows a more compact and light block/cylinder head asssemly. bottom line, pushrod is less efficient overall, but it doesnt mean its a crap engine!

I can honestly say pushrods have come a long way: Mark Wan says

Throughout the years Corvette persisted in using push-rod V8s, even though technology fans like me doubted the future of such engines. Overhead-valve V8s may never match the efficiency of dohc V8s, but they are relatively simple, cheap and lightweight. In the C5, GM successfully made its LS1 V8 so compact and lightweight, while raised its revvabiilty and efficiency significantly.

Back in 1984, the C4's 5.7-litre V8 pumped out only 230 horsepower. 13 years later, the same displacement produced 345 horsepower in the C5. Z06 even raised the horsepower count to 405, all achieved without any increase of displacement. For the same period, Porsche 911 Carrera had its power raised from 231hp to 300hp only, even though it switched from air cool to water cool, 2 valves to 4 valves per cylinder along with an additional 200cc. One can see how far GM's push-rod V8s had progressed.

theyre relative development trumps any particular developments in ohv efficiency - these engines are perhaps already reaching practical engineering limitations.

There are further issues pushrod cant avoid, e.g only now are they developing vvt mechanisms foe the single camshaft (and a limited one -30 deg. phase) - yet this is easier to implement in ohc. If i was designing an efficient engine i would want to focus on maximum breathing control to ensure precise fuel burning hence increase performance and improve emmisions. I would certainly utilse heteregenous mixture control and direct injection like the veyron.

does anyone know the overall boost pressures of each engine?

I personally think Mark Wan is just being demagogic in his Porsche flat 6 v GM V8 comparison. It's not the same extracting power from a 5.7-litre engine than from 3.4-litre...

from my maths the said example raised gm by 20 hp/l wheras porsche by 15hp/l (porsche went 3.4L - 3.6L didn't it?)

edit: But..as you near the boundary of engine performance it is harder to raise hp/L therefore i am just pointing out that GM where not at the same level as porsche in this respect..

They went 3.2, 3.6 and then 3.4-litre with a brand new engine.

The Veyron engine is not 2 bolted on engines.
And there are 1.3L DOHC I4 bikes that will get times close to the giant pushrod motor. There are also chunks of lead using 3000 year old Chinese black powder that will beat any pushrod engined racer you care to mention in 0-200.
If you want to keep making silly comparisons.

It is a silly comparison and the conclusion is just as silly. If we are supposed to be impressed by the Hp/L then a quick calculation shows that the modern Chevy has only just caught up to the old 2v air cooled Porsche.

Wrong. The Ultima can generate more 'Gees' that the Bugatti but to to so it has a racing interior (or lack of interior) and racing ride and comfort. The Bug is like what the Titanic was intended to be: Opulent, imposing and faster than anything else out there.
It is telling that anything which matches the Bug in 1 area can do so only by severely compromised others.
