WRONG.

Weight has hardly any affect on top speed at all. Top speed is almost entirely limited by the ability of your engine to overcome aerodynamic drag.

Drag squares with velocity, so it adds up extemely quickly.

Please, children, don't argue with someone who is much more knowledgeable than you in the automotive subject.

I would agree with 91ttz, a 300lb person can still run as fast as a 100lb dude, it doesn't mean he will be 1/3 slower, he just cant accelerate as fast.

did you read? drag causes more weight, yes I know you need some weight to keep you on the ground, but there are ways around. make the car lighter, I know it sounds like ricer knowledge, but it does affect you at higher speeds.

rotary and boxer. they're small but packs power, like vtec.

me thinks 91ttz doesn't know the difference between weight and mass...

Actually that has a W 16 Engine.

Yep sorry your right, but 1001 BHP in a road car Only does 7 miles per hour more then a Mclaren F1

weight. if they could make the bugatti lighter it would go faster

Are you talking about top speed? He's talking about top speed.

You mean downforce and not drag, right?

So what does the downforce do? Increase friction a bit?

As opposed to bottom speed?

Huh? How does drag cause more weight? If you tow a parachute behind your car, it makes it heavier? NO.

Rolling resistance does not change much with speed, by top speed it's only a miniscule influence. But aerodynamic drag squares with speed. As you can see, after a few mph, drag overcomes rolling resistance as the predominant cause of parasitic drag, and as the speed gets higher the margin gets wider and wider. By the time you're up near top speed, nearly all of your parasitic drag is due to aerodynamic drag.

Put it this way- a person doesn't even produce 1 hp but he can easily put a car to running speed. However, by top speed, the drag is eating up everything the engine can produce. By about 175 mph, my car's engine putting out 400 hp can't push it any faster. Wind resistance is eating up all the power that's getting to my wheels, about 340 hp.

You still need to explain how weight affects top speed.

anything without a computer or electronically controlled aspects. something where you have to know whats going on to fix it, not just look up an error code or plug it in to a computer.

drag cant cause more weight, thats not possible.
drag can cause downforce, but not weight.

i think he's trying to say downforce.

 

[91TTZ]

Sorry, but it's time for me to own you.


educate yourself.

A common misconception about attempting to go fast is that it's important to get the bike light, as vehicles must be in most other forms of racing. If you have enough track to truly reach top speed, however, lightness becomes irrelevant. Light weight only helps acceleration. Once you stop accelerating, assuming that you won't need to change direction, light weight becomes a negative factor rather than a positive one. In fact, more weight is better because it lessens wheelspin

educate yourself more.

While a heavy car would accelerate slower, top speed would be affected very little.
