Here is a fun video to watch. I just wish the morons would have done it in a little less traffic.

I love speed as much as the next guy, but it's ***** like this that ruin it for the rest of us... at least they were not caught or cause a crash. I admit to driving at extreme speeds on public roads, but never in traffic, even when I was much younger I didn't drive that fast in traffic. Cool video though, pretty damn fast cars for only 4 cylinders!

Took 'em long enough :P

+1.... i have done this a few times. but in a place where there wasn't anyone on the road. not saying it was right, but i wanted to know what the car could do once my instruments could display the actual speed i was going, and i no longer was stuck running the not-so-great, stock exhaust....



this video does indeed look faked... or some kind of optical illusion from the camera lens or filming at night.


i was actually going to post this video a few months ago as a good example of how our speedos mean very little, and can be off by as much as 10~12 mph. ask the guys who run open road races, texas mile etc in their P-cars... as they have pointed out and as i have said dozens of times.


if the video is real, their speedo will be off by 4~5 mph even if they were running the correct tire size.... which they clearly, are not.


the 968 speedometer is set to read 25 mph per 1000 rpm in top gear, but the speedo begins to show a defect of about 0.75 mph for every 25 mph (even when your running the correct sized tire).... and in order to have 25 mph for each 1,000 rpm that tire will need to be 25.5" and it's obvious the guys in the video are not running the bigger tires, so you can add on another 7~8 mph of defect to that.


so, if it looks impressive that they're able to wind the speedo up that high, that's because they're technically running a lower ratio in top gear (tires). this can be confirmed by downloading the mp4 to your computer and then slowing it down w/ VLC media player... keep track of the clock.... count the stripes and you'll discover they're going like, 144~145 mph.... on older cars running the short tire combo, partially clogged cats, you'll be closer to 145 mph, just as the video seems to demonstrate....



the "148" mph in the clip below seems a bit more like it... more than 1/10th mile (663 feet) long trainset clears the gun in about 3 seconds. (the acela reaches 150 mph on a few sections of track in Mass. and RI).

anyway staying with the tachometer, here's how i calculated my 163 mph top speed run from last year;


you all can just plug in your tire specs for rev/mile, speed at 6,500 rpm, etc....



running new 26.65" Dunlop 9000 275-35-18 @ 36 psi...


according to Dunlop the tire produces 807 revolutions per mile.... that means the tire's circumference is exactly 78.51"....


on a 968, 6th gear is 0.778..... and the differential is 3.778 ... making the car's absolute ratio is 2.939 to 1.


so your rear axle is making exactly 340.2 revolutions per 1000 rpm.....


there are 63,360 inches in a mile...... and the dunlops i'm running make 26,710.1 inches of forward movement every time my engine turns 1000 times in 6th gear.....


or 0.42156 miles per 1000 turns of the engine, or 2.740146 miles per minute at 6,500 RPM (rev limiter).
....

multiply that number by 60 minutes and you get .... 2.74014599 x 60 = 164.41 miles/hour at the limiter.




first, after installing the bigger tires, i was unable to get the car past about 140~142 mph...... but after dumping the stock exhaust, and changing to the 2.5" straight pipe/glasspack combo i went out somewhere near nebraska on a cold, 15 degree night at about 3:00 am... and i was able to reach about 163~164 mph with that crispy dense air...


this highway was almost perfectly straight and the car needed about 6 or 7 miles to reach top speed... the car ran up to about 150 mph quickly where it encountered a wall of wind and the increase of speed slowed... the last 7 or 8 mph required about 4 more miles of road... i did it again this past summer with a little more wear on the tires and got the car up to about 161 mph...


the car always feels fine, but unlike that cold night from a year ago, this time, something started to smell horrible. don't know if it was the bearings on the torque tube, or the input shaft, clutch or what.... didn't smell good. but not quite the "oil refinery" smell that you get just before your engine blows up so, who knows.



i also have my speedo wound back about 4 mph so it reads exactly 100 mph @ 4,000 rpm.

on interstate 80 i ran 129 miles of mile markers a couple months ago, and the odometer read 128.3 miles



if you really feel the need for speed on dry land, see @ 1:10 of this clip, sick !

Im mixed about this as well...

IDIOTS FOR DOING THIS IN TRAFFIC!!! blow a tire, break a tie-rod, lock a CV and stuff's gonna go wrong in a hurry and they will more than likely take someone else out. Im All for going fast as long as you alone will be the only casuality.

That being said, I love to see a car at its peak. I have my high-speed stretch of our highway here, 4 miles of 2lane with walls on each side, always vacant at night, and usually every time it is I push it to the floor to see how fast my ol' dog will go.

And +1 for listening to System of A Down

whatever you do, make sure the PO didn't sell you a car with ancient tires! check them! LOL

I call shenanigans.

I don't know where these people live, but when the video starts and they're doing "120" they're BARELY passing traffic. Didn't know minivans and 80's pickups ran triple digits for the hell of it. I'd believe 75-80 when they pull out into the left lane.

I've sped like this in the past, and traffic whipped by WAY faster than what they're showing. It's nighttime, and most people do 65 in a 60. That means at their "160" they're doing 95mph MORE than traffic. Don't think so. Also, they're really, really hamming it up about the speed and getting nervous.

I'd say there's something wrong with the speedo, and they're in 4th.

lol. also the video starts with "it may not look like it, but were going...(dramatic pause)...120 mph"

hmmm... maybe, maybe not.

No way were they going as fast as the cluster indicates. I don't think they even broke 100mph since the closing rates were about 30mph to traffic.

rgs944

There are some freeways in Southern Cal. that a cop might give you a ticket for going as slow as 60mph. I have been on plenty of freeways that 85 or 90mph is an average speed in the fast lane. I did a lot of driving out there in the 90's and my guess is that things have'nt changed much. The speedo may be off a little but I do not think the video is fake.

pettybird

Then you've never passed someone on the freeway with an 80+mph speed differential. I'm not suggesting you do, as it's dangerous, but cars go backwards at an alarming/amusing rate. Even taking your 85-90mph left lane speed, they're passing traffic at 30+mph at the beginning and 70+mph at the end. Not happening. And no way the base model Dodge Caravan is cruising along at 110. Look again at the beginning of the video.

Two kids making a fake youtube vid to impress the ricers. That's all.

odurandina

a bit more real... thinking maybe 135~140 mph in the first video...

Horse hockey. No way they were doing 161 MPH, let alone much over 100.

OD's last video looks real.
