g's on the skid
 

what does a stock 00 SE pull on the skidpad?

believe its around .8? i'll hafta check that tho

Performance Data:

Acceleration: sec, 0-60 mph 7.5-seconds
Standing quarter mile: 15.1 seconds at 94.4 mph.
Braking: 60-0 mph, 128
Lateral acceleration: g,0.80
EPA fuel economy: mpg, 22-city/28-highway
Est. range: miles: city/hwy. 407/518

Just found that online

I saw in road and track that it was .84 for the SE

yes and SE with 17"s also...i believe .84 more then .8...b/c the maxima handle close to my sport t-bird and those pull .86 on the skidpad...but what ever the case is thats pretty good

Just for comparisons (from 12/98 Motor Trend)
'97 Stock SE .83
'97 Stillen S/C SMX .86
'97 Stillen SMX .90

I know this isn't the same but i got 3 g's in a corner and I can prove since it's stored on my Apex-i RSM.

The stock 2k maxima pulled .82 g's on C&D mag.!!!!!!

What happened. Did you hit something?

3 gs?.....holy god..lol...is that even possible in a car?

Anyone have data on a modded 5g? Lowered, RSB, FSTB, 18/19s? Be curious to see. I throw it around like crazy when I set the struts tight

No way.....your car would be lucky to pull .9 g's on a skidpad. A Z06 pulls under 1 g and it would take nothing short of a shifter cart to pull 3g's in a corner.

this one thunderbird i saw did pull 1g in the skid...with buyable suspension stuff...its a shame the max's dont have irs.....1g would be so easy...but yeah i guess 3g's was a typo

Proof is right here. top is left to right bottom is front to rear. Highlighted is the highest valve set. As you can also see that the car is in my garage on level ground so it's reading 0.00 L-R and F-R.

Meters like this read instantaneous peak measurements. Reported numbers are usually calculated averages driving around a test circle of known diameter. Very different animals.

I am not sure how that unit works, but there is NO WAY a Maxima will pull 3 g's on a skidpad(constant radius turn). Again, a Z06 will pull just under 1g. A Maxima running on R compounds would have trouble pulling OVER 1g on the skidpad.

Once again this wasn't a skid pad. this was going too fast into a corner and turning into a corner without sliding I was going to fast where I almost lost control but got slowed down b4 going into the other lane.

off Apex-i website:

The G- F/R, R/L is a function much like the REV [Y] function. It is a 2D Trace of the G forces being exerted upon the vehicle while in motion. On the graphical display, the center of the graph denotes Zero G. Acceleration moves the pointer up, while Deceleration moves the pointer down. Cornering G's can also be plotted as left and right on the graph. All data may also be stored into memory with up to sixty seconds of replay time.
Note: This function is only available with the use of the optional G-Sensor.

One of the most exiting of the new features is the option to utilize the revolutionary A'PEX G-Sensor (Sold separately.). The G Sensor allows the unit to measure G forces in 4-way front/rear/left/right directions. This data can be plotted in a graph display to map acceleration characteristics and lateral G's on the race track, or used in an array of new features including: Highly accurate 100m/200m/400m times with trap speed and wheel-spin correction, Horse Power Calculation, and Loss Power Calculation. By taking advantage of the optional G Sensor, the user can produce extremely accurate power measurements

So you are telling me you can corner as hard as a shifter kart in a Maxima.....This is pure comedy. Something is wrong somewhere. Look at what RACE CARS pull in corners and then come back and tell me you pulled that number legitimately. You wont pull more than ~.9 g's in a Maxima on street tires. BTW, What kind of tires are you running?

From the Skip Barber Website
"The spaceframe chassis, built by Mondiale Cars of Northern Ireland, is powered by a 16-valve, 2-liter production 4-cylinder Dodge Neon engine tuned to deliver 135 peak horsepower. Our nimble Formula Dodge can accelerate from 0-60/mph in 4.5 seconds and will stop from that speed in less than three seconds. Riding on BFGoodrich tires, the Formula Dodge can generate more than 1.1g's of cornering force, providing plenty of scope for exploring the limits of adhesion as your skills and confidence develop."

A year ago CART cancelled a race at a high-speed oval in Texas -I dont remember which- because they were reaching close to 3g's in the corners and the corners -and the race- was long enough that driver safety was an issue.

It took CART cars with wings, ground effect chassis, 18 degrees of bank and 230 MPH to generate 3gs so....sell your machine, it's definitely defective.

BTW, I experienced several moments of 3-5gs in a two-seater acrobatic airplane and there is NO WAY you would even come close to that in a car, except if you hit something.

I think that there are some cars that can pull 3 gs in a turn/skidpad

But they need a B-i-i-g skid pad so that they can be going fast enough for the aerodynamic aids to pin them down.

F1, CART, Indy car ... maybe. Maybe even some of the LeMans type cars.

Any street car? The only way you'll get 3gs in a street car is to hit something.

Your meter was sliding around, and bumped into something, or you bumped something in the car. There is absolutely, positively, no way you can pull 3 Gs cornering in a Max.

The sensor is solid it's in a place where nothing can hit it. I can get 1.05 g's going onto a onramp. Don't believe me then but I still got proof. Tell you what I will reset it and even recalibrat it and pull 1 g on a onramp. For your info most race cars like nascar and indy cars are pulling more the 3 g's.

Also I am on snow tires when I did that and snow tires got mad grip on dry pavement.

You guys are all morons. Ever heard of instantaneous G's ? American fighter aircraft are capable of pulling an instant 12-15 G's for a couple of seconds (if they weren't limited to 9)...

Skidpad is more of an average G force (maximum turning traction for a given speed). Most cars could do an instant 2-3 G's at speed, but they'll never hold the turn.

Hey, QuickMouth....the fact that you may be a wee bit more enlightened (not that I think u are) does not mean we are morons, so dont be so quick to diss folks ur not entirely familiar with.

For one, I'm a Physics major, for two I am a pilot -and with those two experiences, I bet I know a ****load more about Gs than u do so please, dont call me a moron.

"I can get 1.05 g's going onto a onramp. Don't believe me then but I still got proof. Tell you what I will reset it and even recalibrat it and pull 1 g on a onramp." You're lying and/or your equipment is faulty. Sorry, it takes an exotic (or a non-exotic with a heck of a lot of suspension modifications and tires) to maintain a constant 1g+ around a corner OR on an onramp.

Or, maybe you're right. Maybe your car has better grip than a 911 turbo and holds right there with a Saleen S7.

OK Galo, you're excluded from the moron comment. We have the same EXACT background and education... :)

And by morons, I truly mean that people are being idiotic for arguing without even attempting to look any of this information up on the internet. It's all right there , ripe for the plucking...

I have a short temper today for some reason...so forgive my harshness.

Not calling anyone names, BUT, you don't know about the CART race at Texas. The issue was due to the g-forces having a greater vertical component than what the drivers normally experienced (mostly lateral g forces). Top racing category drivers experience 2.5 to 3 Gs without a problem, but these are lateral forces. The 24 degree banks at TMS created much higher vertical forces than the drivers are used to, with one or two drivers nearly blacking out and most of the others becoming at least dizzy. Imagine what 240 laps would have done.

Look up what race cars do for instant G's and tell me that a street car on street tires can pull 2-3's g's briefly. Street tires dont have enough traction to hold 3 g's and would break away near 1.

No...

You look it up and post it here. I will not do your research for you. Let's see if you can even find anything on today's current generation racecars.

And what part of "they'll never hold the turn" did you not understand?

this thread is pure comedy....

I'll have to post it to ClubSi just for S&Gs.



Anyways, to the guy with the maxima that carries 3gs worth of lateral forces. Your may have hit a bump or had torque steer for a 1/4 of a second, where the meter registered a 3.7G. It's NOT substained (meaning, you cannot carry 3gs worth of grip thru a turn).

Consider this, a shifter kart (No suspension, the chassis takes up most/all of the suspension twists and bumps) on tyres that are stickier than EVERY street tyre in production today can carry over 2g of substained lateral Gs... and that's pushing it hard! I'm sure instantenous G's is a bit higher.

Also, handling is biased... a Maxima may be a better handling car than a Vette to some people... that is, if they like understeer.

I'm quite unable to find a meaningful comparison of continuous vs. instananeous, insofar as instananeous being capable of a 2-3 times greater magnitude than continuous. At face value it feels like pseudo-science to me, but if it's not I'd love to learn how a car that is, at one moment capable of 3 G, can not in fact hold more than .8 over any meaningful length of time. The shift in the weight of vehicle could surely account for some, but I'd be very surprised if a .82 G rated car could hit 2 for even a split second.

This is aside from the onramp though - no maxima can get 1+ on an on ramp unless that ramp's camber is very high (and then the number is meaningless anyway).

I already looked it up and posted it right from the Skip Barber website. You can find plenty of data on the G's loads on various race cars. And BTW, race cars can hold a constant 3 g's smart guy.

From Skip Barbers book, Going Faster the art of racecar driving:

GTP intrepid 3.0 G
Indy Light 2.7 G
Indy Car 3.3 G
Forumla Dodge 1.1 G

ALL SUSTAINED...geez people on this site really need to do some research.

Those numbers look to be correct. And yes, those are SUSTAINED numbers...like skidpad numbers. I am very willing to bet that you will not be able to find the instant numbers (too many variables to have a set number)...

I never said I can hold it at 1 g on a onramp I said I can get it to register 1 g on a onramp. That I could register 1 g's when first going into the onramp but not carry it through. Plus I am not going to stare at my gauge while driving I look at it after I feel I am at a safe driving point where I can look at it. Maybe I should been more clear that these numbers that I have are not holding numbers. We all come to a logical conculsion and in all we all are correct

Comedy gold that I can't believe i missed in my original post.



I guess that's why all those race cars use snow tyres... imagine a Leman car with snow chains, hahahhhahha!

Only then, could it achieve 3.7G



oh, by the way, getting your gyrometer to register 3.7G isn't exactly hard... substained G forces would be harder.

Captain Obvious to the rescue again. We've only resolved that several hours ago...

There Ca... um, Driven, I fixed it for you :)

MyOwnNismo, you have a nice lookin' max there, and I'm sure it drives real nice, but you gotta stop fondling that POS Apex-i crapometer--you're gonna rub the chromium finish clean off that thang.

its possible to pull 3 g's, but here is the only feasible way in a street car.

1) That would be an instantaneous reading, most F1
cars barely can sustain 3gs in a corner
2) you would have to do it on a severely banked,
sharp, corner (~ 25-30 degrees and a 90 degree
turn)
3) You would have to be travelling ~100mph

Now, I have yet to find a public road or even a roadcourse with public access where that type of corner exists. There is one that I have driven (nodschliffe, the nurburgring germany, "karusel" corner) but i only managed to get 1.18g measured on a Gtech competition meter driving a 2003 E55AMG.

The more than likely thing is that the Apexi unit is miscalibrated, or one of the sensors is loose, causing the errant reading. Double check everything, recalbrate, take the corner again and see what you get.

No, we are not all correct you jacktard. The original poster was asking about lateral acceleration for Maximas. You came jumping in with numbers pulled out of your little gadget, pretending they mean something. They don't. You still haven't contributed anything meaningful to this thread.

And Quicksilver, do you think those 2-3G numbers for some of the most specialized cars in existence somehow helps this discussion? Do they have *anything* to do with a Maxima? Did the sacred Skip Barber book quote skidpad numbers? Are there any production vehicles that can even come close to those numbers? What is the connection between industry standard skidpad numbers, and the BS that's been posted in this thread? Yay, nice expert "b-b-but I have a degree in physics!" comments :rolleyes:

Apology accepted...pliz accept mine as well, I'm having a not-so-hot hair day myself... :thumbsup:
