How to jump a car.
�
�
I was watching some Rally highlight video's and some WRC coverage and you see that the cars can go off the same jump very different. So my question to all you rally people is how do you land on all four instead of nose diving.
Cheers,
Chris
PS I have no desire or plan to jump my car just curiosity

i think it's all in the weight distribution on the wrc cars. little things like the passenger seat is set lower and further back. that's why it always appears that the driver is sitting really close to the wheel or the co-driver is a tiny wimp, but in fact it's because the co-driver is sitting lower and further from the dash.
weight distribution. if you do enough searching, you will be able to find a diagram of the wrc vs. road sti. the differences and all...i've seen it, but forgot where!

Less weight at the front, more weight at the back. Plus skill.

Weight distrobution and suspention travel... Ever notice how far down the tires are from the body when they are in the air?

With bikes and vehicles with big tires staying in the throttle, continuing to acclerate the wheels keeps the nose up. Lifting off the throttle or touching the brakes brings the nose down. Not sure if it works with rally cars having relatively little mass in the wheels and tires versus the body. Works great with motoX and monster trucks... Even stadium trucks do it, but they have more wheel/tire mass to play with.

It also had to do with the momentum of the car. Accelerating off the jump will keep the weight transferred to the back of the car, which will help keep the nose up, resulting in a more level landing. The worst thing to do is to be slowing down as you launch, as that transfers all the weight to the front, which can result in a landing like this:
[IMG]http://rally.racing-live.com/photos/2002/australie/diapoa_223.jpg[/IMG]
If you watch, when they�re approaching a particularly nasty jump they�ll hit the brakes to slow the car down, but get right back on the throttle before they hit the jump to keep the nose up.
I have also read statements from former WRC drivers that the best way to land is to have one (front) wheel touch down (slightly) before the other. It allows the suspension to work together better, rather than just being slammed all at once. If you have a modern WRC suspension, I don�t think that it matters much, but if you�ve ever seen footage of the mid-80�s, landing after a jump was a scary proposition (the Group B Quattro�s used to rebound like a bouncing basketball :eek: )

I've always heard/read and have followed to make sure I'm on the gas over a bigger jump, if necessary, brake slightly before a jump then accelerate again to keep the nose up.

Wife was watching videos over my shoulder. Apparently I'm no longer allowed to think about rally anymore. :rolleyes:
However she just might get me a new helmet :banana:
It would appear that jumping in a car is similar to a ski jump in a downhill. Don't do anything that would let the car lean forward and hold on for a ride.

| patr | 12-25-2004 07:25 PM |
just floor it and deal with the consequences
if you have to slow down, do it before you even get to the jump, like way before, so that you are already on the gas (not really on the gas, but weight on the back) on the jump. It *is* like a bike
the 04+ STIs tend to fly nose up at high speed (greater i.e than 160 km/h)
if your car was built like a tank, its best to not lift at all except a slight pause to not spin the wheels. Dont do sudden throttledrop etc you nose dive
in the air, if you spin the wheels too much you will break shafts on the landings

Thanks everyone I was wondering if there was some technique to it. It appears there is and it is to not get scared of the upcoming flight before you get to it, and make sure you gas through the jump.
Thanks everyone.
PS this is why I absolutely love these forums. I ask a question that I was expecting to get a bunch of jumping your car is bad (duh!) post too. And instead I had a bunch of people who actually have experience jumping there car (like the illustrious Pat Richard) telling me how they do it. Thanks again

I see on that Pat. Richard video that the car bounces around a lot after the landing; this looks spectacularly dangerous! :eek:
I've had my car airborne before and it didn't bounce. I'm guessing the bouncing happens when you jump at very high speeds?

dont do what is in that video clip
I wouldnt do it again, the bounce was dangerous. the question was about how to attain level flight, not anti-bounce... if you dont want to bounce fly lower or else play with the shocks. Remember dont just stay on the gas or else you WILL break shafts
if mopho is on this forum he can back what I am talking when I say that this stuff is dangerous. DONT DO IT.

Oh, trust me, you don't even have to ask!!! :lol:
Having said that though, I have a LOT of admiration for anyone who has the balls, and, obviously, the skill, to drive a car like that, specially you, Pat! I have purposely jumped my car before by driving up and down an inclined street with straight cross streets (effectively forming ramps): At 45MPH -50MPH all 4 will leave the ground and it is a very scary experience, but nothing like what you do in that video. I've also had my car accidentally leave the ground because I was going over 100MPH and the road had an irregularity which appearently was enough to allow the suspension to load and unload fully (probably only went a couple inches off the ground). Again, very scary, but no bouncing involved. I was just curious as to why your car bounced in that video; I guess at very high speeds the car acts like it is a lot lighter? How fast were you going, BTW?

I figured as much. I would imagine you would want to avoid that again. It worked out well for you that time but the second time you might not have been as lucky to keep it going straight. I had just opened this thread and thought of that video of yours. I couldn't imagine being the codriver or the driver of a car that bounced like that. That is the beauty and horror of rallying. You never know exactly what is coming up, only a good guess.
Wasn't there a fairly large cliff on the drivers side of the car too?

Do you mean street cars ( :eek: ) or rally cars like your SRTC car?
(which does have the front small lips)
I noticed the N9's at Suttons have the big rear wing but not any of the front bits:
[img]http://www.davidsuttoncars.com/images/showroom/55_1.jpg[/img]
With the bug-eye's I remember the Prodrive guys seemed very paranoid about always using the small wing; they didn't recommend the big wing without a front lip (ignoring homologation issues here...)
Or let me put it another way - I assume this is an aerodynamic balance issue?

after watching those videos I wonder if the teams/ manufacturers should spend more time on stablity when the wheels are not on the ground. Although I would think it would be better to work on ways to keep the car on the ground as much as possible where you can get the power down.
| patr | 12-27-2004 02:06 PM |
glenn the new shape cars
(dont know why everyone calls them by prodrive numbers because lots of them arent)
at high speed (only VERY high) they will pull down in the back a lot more relative to the bugeye. the front lippies dont make that much of a difference (small but the thing still basically wheelies on big jumps with them or not and they get ripped off in about 5 seconds).
I have some in-car videos of this but i dont think i can post them
the brockway jump is 'all glam' but there is many other instances where its worse and trust me, dont brake in the air.

brake = transfers all of the weight/momentum forward
then when you gas just before lift off
it transfers all of the weight/momentum back to the back of the car
allowing for flat, level air travel :D

no, u brake to slow down to get less air
if you dont care about the size of the air leave it pegged you'll fly sort of flat unless there is a big drop too.

I've never braked, before, during or after, and have never had a problem. But at Tall Pines last month, I bottomed out the DMS suspension for the first time on a landing. I think it really dropped off more than I was expecting. Didn't get far enough to run that same stage a second time :mad:

[QUOTE=RRR-K2]It also had to do with the momentum of the car. Accelerating off the jump will keep the weight transferred to the back of the car, which will help keep the nose up, resulting in a more level landing. The worst thing to do is to be slowing down as you launch, as that transfers all the weight to the front, which can result in a landing like this:
[IMG]http://rally.racing-live.com/photos/2002/australie/diapoa_223.jpg[/IMG]
If you watch, when they�re approaching a particularly nasty jump they�ll hit the brakes to slow the car down, but get right back on the throttle before they hit the jump to keep the nose up.
[/QUOTE]
In this particular case (WRCAustralia 2002) ALL the FocusWRC's nose dived (Sainz, McRae, Martin). Why? They all varied thier approaches on speed and shifting weight transfer before the jump, but the Focus was so off balance, the rear of the car ejected off the cattle gate. The FocusWRC2003/2004 had revised weight distribution (moving the motor back and tilting it) in combo with the new aero pack, thus, the balance was much improved.
Air is always the slowest way through a stage. Lapworth once said (Commenting on the Virtual Spectator) that on the Ouninpoja Stages that the WRC car would be in the air for a 1:30 if you added all the flight time up. If you bring that car to the ground, it gain that time back and then some.

[QUOTE=WRXedUSA]In this particular case (WRCAustralia 2002) ALL the FocusWRC's nose dived (Sainz, McRae, Martin). Why? They all varied thier approaches on speed and shifting weight transfer before the jump, but the Focus was so off balance, the rear of the car ejected off the cattle gate.[/QUOTE]
Yeah, I know that was the cause in this case. I just wanted a photo to demonstrate a hard nosed landing, and I KNEW that shot was out there� :p

[QUOTE=crofrog]How to jump a car. [/QUOTE]Hope you find this helpful:
When jumpstarting a car, consider safety first. If at all possible, wear safety glasses. Also, never smoke or use matches while jumpstarting a car or handling a battery. Batteries can release explosive gases.
First, make sure that the cable connectors to the dead battery are not damaged, broken or have frayed wires. This could also be a reason that the car is getting no power, since a charge cannot freely pass through damaged cable ends. If this is not the problem, follow these ten easy steps to jump start a car properly and safely:
(1) Move car with the "live" battery as close as possible to the car to be jumpstarted without the cars touching.
(2) Switch off power to both cars and make sure that they are in park. Set the brakes.
(3) If any corrosion is present, scrape this off with a small knife or other object. Do not let corrosion come in contact with bare hands. If possible, wear safety gloves.
(4) Connect the metal clamps of the red cable to the positive posts of each battery. The positive posts are marked "+" or "POS". The negative posts are marked "-" or "NEG". Make sure you do not allow the metal clamps of the red and black cables to touch each other.
(5) Connect the clamp from the black cable to the negative post on the car with the live battery. Connect the other end of the black cable to bare metal on the frame of the car with the dead battery, the grounding connection. This is safer than connecting the black cable to the negative post of the dead battery.
(6) Keep the cable clear of the fan and fan belt at all times.
(7) Be sure that the ignition is off in the car with the dead battery and start the car with the live battery, revving the engine lightly to charge. Attempt to start the car.
(8) When both engines are running, remove the cables by first taking off the black grounding connection on the body of the car and then the other end of the black cable. Remove the two red cable ends last. Make sure that no objects are let under the hood of either car before closing the hood.
(9) Do not turn off the engine to the car with the dead battery until you get to where you were going. If possible, let the car run for half an hour to make sure the battery has a full charge.
(10) An incorrect battery connection could cause an explosion so make sure to connect red to red and black to black.
If these instructions are followed and the battery will not charge or loses its charge, take car to a mechanic. The problem might be elsewhere in the ignition system.

Here's "How not to jump a car":
"A lawsuit against the driver in the videotaped Jackass car stunt, dormant for a year-and-a-half because he couldn't be located, inched forward this week after he was found in Covington.
The suit was filed in Kenton Circuit Court in May 2001 on behalf of an Independence teen who suffered a broken right leg and left ankle when he tried to jump over a car driven by the defendant a month earlier.
It remains unclear if the boys were inspired by MTV's controversial show Jackass, in which people send in videotapes of their dangerous stunts. But early in the investigation, that's what police were told.
The Enquirer is not naming the boys because the incident occurred when they were minors and the criminal case remained in juvenile court.
The injured teen has healed after incurring about $25,000 in medical bills, his attorney, Eric Deters, said Wednesday.
Mr. Deters said he requested the driver's auto insurance company pay half the medical bills, on the premise that both boys were willing participants in the stunt and share responsibility for its outcome.
"This is a classic example of two people equally at fault," Mr. Deters said. "We wanted them to pay half. They refused. This isn't about someone (his client) not taking responsibility."
Steve Wolnitzek, attorney for the driver, disputes the amount in medical expenses and says the stunt was the injured boy's idea.
"He had done numerous stunts in the past," Mr. Wolnitzek said Wednesday, "and now that he gets hurt, it's someone else's fault."
He said medical records he's received show expenses of $13,764, of which about $11,000 was paid by the driver's insurance company under Kentucky's no-fault system.
The suit alleges, among other things, that the driver "failed to operate his vehicle in a safe manner" and in a way "consistent with its intended use."
The injured boy was supposed to jump over the car as it approached him on Sidney Drive in Independence on April 23, 2001.
Instead, his ankle struck the front fender and he went airborne, crashing on the hood and windshield."

Good point, former SuperCross Champion Jeremy McGrath used to talk about that all of the time. One could do more about it on a bike though.
In a car, if the bump is big enough to launch the whole vehicle, chances are that the only way to avoid it would be by slowing down. In order to go faster, we would need huge suspension travel (like prerunner/baja trucks).

its all misguided and fourth hand and out of context really, otherwise no one would ever get air
yes, for armchair enthusiast theory, accelerate all the time wheels on the ground
On high speed jumps, the time you lose by not accelerating when you are in the air, because you are in the air, is generally A LOT LESS than the time you lose slowing down.
On low speed jumps, the inverse is true.
In general, you want to not slow down, and not get air. balance both and ye shall fly happily

That's exactly what I was just thinking. Think about it.

[QUOTE=patr]glenn the new shape cars
(dont know why everyone calls them by prodrive numbers because lots of them arent)
[/QUOTE]
BTW I said N9 for Sutton's cars because they are actual Prodrive built cars. I could have just said new shape though. :)
