Your post is pretty much spot on, but I had to point this out. A 1970 Hemi Cuda might have been fast back in its day, but today it is far from it.

And I've been in some horribly fast cars back in the day, such as a 1970 Hemi Cuda...was a passenger in that while street racing up in D.C.

really people..

a car is not doing top G's people can still move in fighter jets and hell the space shuttle..

only time i ever hear of this is as a setup for a joke. unless you are in very bad shape or a child you can do it.

It also would depend on the person. I've given non-car folks a bit of throttle from a stop before and they're paralyzed, not with G's, but with fear of death. If you have a fast car, you get used to it, but for someone who has only ever been in family sedans and drives like a granny, doing 0-60 in under 4.5s in a car scares the crap out of them.

Yeah, um... just kind of throwing that out there, but feel free to pat yourself on the back for 'winning' the 'debate.' (read: making yourself look like a pompous ass for no reason)

Also, possibly google 'modern F1 car' to have an idea of what I'm talking about. There is not a hell of a lot of room, nor any reason for, the driver's arms to leave the steering wheel.


Now everyone calm down, I wasn't trying to belittle you. It is just a ridiculous notion that a car could be so fast that you can't raise your arms under the acceleration.

And I follow F1. The drivers do take their hands off the wheel to adjust brake bias etc. Modern F1 cars are not as powerful as they were during the turbo era which is why I mentioned that.

Try ~3300 lbs curb weight. Add in a human and you're at 3450-3500 lbs. It's 92% of the weight of the current GT, 55% of the hp, 77% of the torque.

You're also confusing a single torque number with the acceleration ability of a car. I guess diesels with their astronomical torque values must be used for all high-acceleration applications

Stock 89 mustang gt manual took a whole 6.1s to reach 60 mph. That's a yawner. That's a camry these days.

Stock foxbody stangs run low 14's in the 1/4 mile. It's nothing to get an extra 30 horses out of them and also add 3.73 gears in the back which I've done with my 90. Not to also mention adding 30 hp and 3.73 gears can be done for under a grand. Find me another car where you can do that for the money. From 0-100 mine flies. Sure there are faster cars but you'll pay a minimum of double the price to reach that HP/weight ratio. And you're are comparing a 30k new gt to a foxbody which can be had in decent condition for 5k. Let me put 25k into the motor of my fox since your dead set on comparing it to a 30k new mustang and we'll have this discussion again.

You are correct sir. As I said, the carnival ride "The Gravitron" did/does 3 or 4 G's and while heavy, your arms still work.

I new someone would start this crap. Please note that every. single. post. I. made. explicitly. says. stock.


Oooh, 14s 1/4 mile... Again. That's a modern v-6 camry.

Yes stock. A car available for 5k vs one that would cost 30k is a perfectly fine comparison.

What car do you drive btw?

FYI the 230hp 1989 Supra Turbo did 0-60 in 6.5 sec and the quarter in 15.0 (based on some random website).

Cars from the 80s are between 23 to 33 years old and perform worse than modern cars -- does anyone really question this?

I think there is something missing from this discussion. Everyone is talking about how easy it would be to reach out with the arm... but what if the coin was farther away than the arm can reach? In such an instance the person would have to lean forward for the extra reach. Who can keep their torso off the back of the seat during hard acceleration?

I hate to be a broken record, but did you ever ride a gravitron as a kid? Or can you do a sit up with your legs held down?

I have done this with my cars... ~500-550 whp.... you all are missing the point here. It isn't about the physics of it, it's about the psychological aspect. My cars are fast, but not "that" fast. They are fast enough that during a pull, your passenger will tense up and and kind of "hold" on... they are scared. Could they physically reach forward and touch the dash? Sure, but at that moment, they are overcome with what's going on.

It's also the whole not expecting it thing. Just like when the passenger seems to be moved around a lot more during acceleration and turning, the driver already knows what he/she is going to do so your body prepares.

This is a valid argument. And WAY to well thought out to be a part of this thread.

My question is... how did you make the coin stay on the dash?

If one G equals 9.8m/s^2 ... oh man, its been 10 years since I took highschool math... calling on JCH13

Yup, and it was valid when I posted it 2 and a half hours before he did

I don't use a coin... some have taped a dollar bill to the dash... I usually just tell them to try to put the palm of their hand on dash

1990-1994 eclipse/talon/laser.

exhaust($300)/boost controller($15)/intake($125) = ~50hp
16g turbo($500)/injectors and fuel pump($200) = another 40hp

Haha, I have to note as an ex-DSM victim (twice!), that this is a horrible idea. The only worse idea is buying on of those piles of shite to begin with.

I think it's relevant that the differential is made between merely trying to move your arm, and to move your upper body forward to something out of reach of a mere movement of your arm. This isn't abnormal either, one doesn't normally sit so close to the dash as to simply reach out and touch it in most cars in my experience.

It's not like doing a situp while your legs are pinned, that's a completely different situation because you are still at 1G flat during that example. In the accelerating car dilemma you have an unsteady rocking force pressing you back.

Impossible to grab an object off the dash? I guess that would depend on the exact circumstances involved. But difficult, sure, I could see that with the right amount of power.

i have a question about speed and power.

My experience is: 1987 Honda Hurricane 600 / 1989 Mustang 5.0 / 2001 Honda Blackbird 1100cbr). I understand power, i done it, enjoyed it. I have a fairly good understanding of speed/power. I know there is more and faster. but,..

I have a friend that claims, he had a street legal car that when he hit the gas, your arms could not pick up a coin off of his dashboard. He says, it had so much horse power, your arms were glued in down position. You simply could not reach for the coin, it was that fast, and had so much acceleration you couldn't reach for it.

Of course this car doesn't exist no more, this is a bud of mine telling me of old times. I'm calling bull on it big time.

No debates, just tell me how much power it takes to pull off this extreme power. I can see this as possible in Funny car and Dragsters, but a street legal car in the 80's, really.

Give me math examples, i know this is not possible back then.

It would have to pull a lot of g's for that.

An F1 car pulls about 1.5g on acceleration according to wiki, and an F1 driver can still reach controls and move his arms even at that.

An F1 car accelerates far more brutally than any street car.

If this is accurate (not saying it isn't; just can't verify), then I believe that answers the OP handily.

Also of note, think of the size/compound of the tires on those cars. Acceleration is not just a function of power, it's a function of grip.

Only argument would be that in an F1 car, your arms are rather locked in place, and most (all?) controls are wheel-mounted. So it's not like you're moving your hand from in your lap to (or past) the steering wheel.

But if your buddy is essentially trying to compare his wheel-driven, horizontally-moving street vehicle to a thrust driven NASA rocket taking off straight up...yeah, he's full of shit.

What these guys said. Unless one is very out of shape you can move your arms under a large amount of acceleration. In-shape people can handle many more, F1 drivers keep their hands on the steering wheels at 4+gs and fighter pilots maintain precise control of their aircraft near g-suit black-out levels of acceleration, i.e. 5-6gs. Your buddy's car would need tires 2x stickier than a top-fuel car's tires to achieve accelerations in that realm... and at that point you'd black out before losing arm control if you were fit. So yeah... hyperbole at best, lying at worst.

Maybe your friend had a coin glued to the dash of his car?

right, unless he has a Saturn V on wheels, no. Think about the drag racers, they can shift and steer.

Pretty sure a 0-60 in 1s equates to about 3 g, that's about what a top fuel dragster will do

3 g might be enough to make it hard to reach for a coin

Impossible on a true street car in the 80s. My dad has friends that would tell the same story.

I've had stock 87-93 notch Mustangs on scales personally. 2,700-,2900 pounds depending on options is accurate for the 5spd notch.

Please do not try and educate as you don't know what you're talking about.
