Fastest Acceleration?

Am I right in thinking that Hypersonic XLC has the fastest acceleration of any coaster in the world?

0-80 in 1.8 seconds... is there any coaster with a faster acceleration?

Thanks in advanced.

P.S. -- those who don't know physics need not answer this thread.

That's the most acceleration I've ever seen, too. There might be one out there, but I'm pretty sure that Hypersonic has the fastest.

Well, Dodonpa in Japan goes from 0-107 mph in 1.8 seconds...now thats fast

Holy Jebus, you're right!

Well it's the same kind of coaster, anyway...

I'm gonna assume Hypersonic gets second place....?

Yeah but ive heard that Dondanopa hurts ALOT on the launch, kinda like getting hit in the stomach with an anvil....

Like I just posted in another thread though...

Dodonpa's acceleration is what I consider the limit for humans. I think of myself as pretty coaster friendly and tough but Dodonpa literally felt like my chest was hit by a ton of bricks!

On the launch? Crap, that must be insane. Ive held my hands striaght up on HSXLC before and you can feel the force in your shoulder sockets. I dont even want to know what hands up on Dodonpa would be like.

Im guessing your arms would rip off and flap around on the ground like a couple of dead fish! But seriously, one of the reasons, besides drag, that CP wont let you put your arms up is the potentialy threat of your arms dislocating! And you can really feel it in your shoulders during the launch.

TTD I think is intence as you get the need to bite down hard and clinch every muscle in your body at the end of the launch (well my first 2 times I did) and the cheek flapping effect!

That's what, 2.7 Gs?

That doesn't sound too terrible =-= except getting hit with that instantly might hurt . . . a gentle swig of that isn't too bad...but it doesn't sound like that ride is gentle!

Xcelerators launch is 0-82 in two seconds which is 41 mph per second.

TTD's launch is 0-120 in 4 seconds which is 30 mph per second.

Hypersonic's launch is 0-80 in 1.8 seconds which is 44 (rounded) mph per second

Dodonpa's launch is 0-107 in 1.8 seconds which is 59 (rounded) mph per second!!!

Out of those the fastest acceleration is Dodonpa but the highest speed is TTD which has the lowest acceleration :shock: .

And that's my math lesson for the day.

heh heh...Elissa was talking about her chest...heh heh

(Great, top of the page...)

However, Dragsters is held longer. So if you are like me, and would rather have a longer launch than a shorter one, then it works for you.

But thats correct. But about having your arms up on Dragster and dislocting your arms, total false.

I ALWAYS have my hands up before it takes off. Its a matter of timing. Once the train slides backwards, its in automatic mode. Ive spent enough time in that station watching the ops work it that I probably could learn it with 5 minutes help, at least whatever part I needed.

The actual "launch" person sits facing the ride and just presses 2 buttons down when they flash...thats when the catch dog engages and the train slides back.

ITs harmless on dragster unless you have some serious medical conditions. I never get much feeling in my arm sockets other than the wind force. Which, in front seat (Where I always sit) is the most fun.

I did just fine. My arms were up defiantly through 3 "ARMS DOWN" messages. I was rebelling against "the man".

I was stoked at the end, hence the "rock on"

No idea on Dodonpa, but Hypersonic feels like it is ripping all the air right out of my lungs.

^Very similar feeling on Dodonpa

^^That's not the most flattering picture!

i like being excelerated. But when i went on Rock'n'roller coaster in WDW, i thought it was powerful. Dodonpa? extremely powerful. I havent been on dondonpa, but i live in a country were there are only like 2 coasters, so i dont get on them much. Only when i am in florida. And hopefully, CP!

^^ That's ok, not many are. But it illustrates my point.

It's similar to the guy at Acrophobia that tried to tell me that it was physically impossible to scream AFTER you drop on Acro. Umm, ok buddy.

I think the fastest RIDE acceleration goes to the G-Force Dragster next to Old Town. When I rode, if I remember correctly, I got my car from 0-117 mph in 1.8 seconds. It was a helluva rush, but definitely NOT worth the money.

Is it one of those rides like at Speedzone?

I had no idea thats how fast Dodonpa goes, that would genuinely hurt

i was going to get on that G-Force Dragster thing but i was really expensive. But it does look good though. I asked the man and he said you experience like 4G's on it.

I forgot about that stupid ride at old town!!

It is really insane too. I didn't think it was as painful at the Dodonpa Launch, but the brakes were awful. If you're the 'passenger' you have nothing to brace yourself on. I ended up with a huge bruise on my leg from the harness digging into me from the sudden stop.

I've only done it that one time, I'd like to try and be the driver so I have something to hold on to for the braking section but no way am I going to pay like $30 or whatever insane price they want!

Okay, the engineer in me has to speak up here. When we are talking about something going 80mph in 1.8 seconds or 120mph in 4 seconds, all we can get from that is the average acceleration. You could have two rides that both reach 120mph in 4 seconds, but one could start at 0 gs and slowly ramp up to 2.7gs while the other stays at 1.4gs for the full four seconds. It's really the launch profile (and the jerk, which is the rate of change of acceleration) that makes the difference.

[/geek mode]

Hmm, very good point.

So, um... which coaster has the fastest jerk?

(ahem)

And Dodonpa is only 100 something feet which means it must be going like 70 mph over that thing, what's it like going over the hill that fast without stalling like rockets?

its 170 feet. if it was going 70 mph over a hill it would probably rip your legs off. 8).......which it doesnt.
