Highest Acceleration G's

[KezR33]

Hey guys,

I asked this in the past, but people misunderstood my question and kept recommending V8s due to their ability to put power down regardless of the where the revs are at. I previously asked at any time, which car provides the highest acceleration. What I meant was at any speed, any time and any car, which SINGLE point will have your eye balls being sucked into the back of your head more than any other.

e.g:

A worked GTR launching from stand still.

A 1000hp Supra the moment it comes onto boost from say... 20kph.

A lightweight snappy Silvia from a rolling start.

An Evo shooting from 30kph.

I dunno, I'm just making shit up, but what car (within a reasonable budget, no Veyrons etc) will achieve the highest acceleration G's at any one moment. Reason I'm asking is because my mate just bought a stock Evo, and its quick, crazy quick, at least it feels that way. I know there are faster cars out there, I've been in them, but they just don't feel as quick. IMO the seat sucking feeling of raw high G acceleration is one of the best feelings you can get from a street car.

I also heard stiff suspension and harder Recaro type seats (like the Evo) has can give the illusion of higher G's too due simply to the fact the seat isn't absorbing any of the force, this true?

What model evo? They certainly are not "crazy quick" from factory. Not at all.

Maximum G force reached is simple once you understand what it means. It means accelerating in a direction greater than what gravity accelerates at opposed to you. So regardless at what speed it is or in what car it is, it is the vehicle that can accelerate the quickest. From a vehicle point of view, it is being able to rotate the wheels as fast as possible without slipping them (losing traction).

So really from a "reasonable" sense of view, an AWD car launching from stand still with a huge amount of power is the easiest to achieve.

My wagon was the fasted accelerating car Ive ever been in. To give you an idea, if you had your sunnies sitting on your head they would be in the back seat by the end of 2nd gear. It was pretty brutal.

[KezR33]

I understand what it is, but I'm looking for peak, sudden, sharp power. Not a nice linear (which is more ideal for track purposes) power curve.

Put it this way (not that I'd ever use this as a basis for buying a car), which car will give your passengers the greatest "OMG I'm going to die" feeling from acceleration alone. Also, I know a stock evo isn't crazy quick, I'm just saying they feel way and was asking why.

[Munkyb0y]

probably coz the evo has a rather large turbo for it's engine size. so it comes on relatively hard compared to other stock set ups. therefore you get a sudden rush of acceleration. thats the G's sensation you are talking about that makes it feel quick.

linear delivery gets you further, but doesnt feel as quick.

Possibly any Dyno pony?

ie, a supra with 1000kw, with full boost within 500rpm?

Phil is right about fastest acceleration producing the greatest amount of G-forces. As for lateral G forces in the corners, that will be the car that can turn sharpest at the fastest speed and maintain traction.

The feeling of G-forces on the other hand, is another thing entirely and there's alot of perception involved. I believe that a car producing the most rapid change in G-force will give you the biggest feeling of being thrown into the seat. In all cars, this will be a launch off the line as you are going from zero G to something. Linear power delivery vehicles, such as N/A V8, whilst feeling fast off the line, will quickly have your senses adjust to the G-forces during acceleration. The speedo will be going up faster than it feels. Non-linear power delivery, like going from off boost to on boost in a car with a massive turbo, will offer a big "punch" that rapidly changes the acceleration G-force making it feel very fast (almost like "launching" from a rolling start). But it's all a matter of perception and your own idea of what constitutes the feeling of going fast. For what you want Kez, it's an engine with an oversized turbo that suddenly comes alive at 4500-5000rpm like a rollercoaster reaching a downhill. Enter the torque.

An interesting way to test all of it is to use a G-tech with constant G-force mode selected.

in any car the most G's you will feel will be launching in first gear. AWD will be the best for this as you can simply side step the clutch at high rpm (and hope something doesn't go bang, LOL).

if you want something that gives the feeling of quick acceleration then a lag monster is what you are after. something with a big turbo that doesn't come on song until high in the rev range. it doesn't even have to make that much power, but if the turbo kicks in hard then it will give the impression of having lots of power. i've been in a 32 with a t71 (i think) on it. didn't make boost until about 5500rpm, made less power than my stock turbo'd 33 and ran a high 14 at the drags, but when it came on boost it felt great. it was just a pity that even a granny in an excel was already a pair of tail lights in the distance due to being gutless below 5500rpm.

Highest G's in straight line aceleration you'll ever experience will be when that 22 wheeler kenworth rear ends you at a set of lights.

Regardless of what car you're driving.

+1, You'll spend a LOT on a car before you get anywhere near one (although I realise this isn't a price vs. performance argument).

The violence of a 1000cc bike is something that few people appreciate until they experience it. As is the case with big power cars.

My K6 GSXR 1000 still shocks me sometimes, even after 4years, and most pillions lose the ability to process the experience until about 5 minutes later, at which point most can only say "I cannot believe how fast that is"

Agreed. First time I was on the back of a Busa on full throttle was the closest I felt to death.

My brothers mental 300rwkw VT SS LS1 was the car I felt the most acceleration G force in car, that thing was scary fast off the line 0-100 in a little over 4 seconds but the hit from 0-60 or 70 that was epic.

[StealthX]

I had a friend with almost exactly the same car as Marc described. Made (only) 325hp, big laggy (5500rpm) turbo in an r32, epic screamer pipe too, i think that gave us an extra few mental kilowatts, felt amazing but would be a pain to drive...

I doubt anything will beat the G forces of those top fuel dragsters that do 0-400m in 3 or 4 seconds. In saying that, doesn't iPod have an application that senses G forces?

I think its called Racechrono..thats the one on my nokia anyway..

i've got a dyno app on my phone. i managed to get 1200+hp at the fingertips, LOL

Lol.

As far as cars go, you can't beat a highly modified AWD car for the perception of gigantic G forces. For example, highly modified GTR with AWD coming on to full boost is a wickedly frightening experience. It's absolutely awesome.

The problem with this style of non-linear power delivery is that you get the feeling that you're really just hanging on for dear life and hoping that you don't lose control. I can only imagine how much more pronounced it is on a sportsbike.

Road car.. R32 GTS4 + 3L + T04z.. limiter launches and 3rd gear pulls.. insane! couldn't even keep the vidcam level
