0-100 Times

[team illucid]

Now I know we all talk about 1/4 mile times, but some of the old timers in the workplace only understand the 0-100 time equation ... I was wondering what sort of times forum runners are doing for the 0-100 dash and how you guys are testing ... I keep getting around the 6.5 mark using a stopwatch but I know it is not really accurate ... how do they do it in Motor Mag etc???

I am presuming that some of the really quick cars on this forum are in the low 4's for the dash, or am I being optimistic :)

[ROGUE]

is a g-tech a fairly accurate way of measuring 0-100 times? :confused:

I believe so ...

[dean]

I tried this a while ago with a g-tech - after about 20 goes of mid-low 5's managed a 4.83 & 4.66 0-100. Be interesting to try with some drag radials.

That's pretty good - are you using standard shifter?

If the QTR track takes measurements at the 330' mark, then thats the equivalent of your 0-100 time. So If you measure 5.7s at 330', your 0-100m sprint time is 5.7s.

Stuff the G-tech. Ive seen many produce ridiculous results. Take it to the track and see for real.

0-100m and 0-100 kph have no relationship at all.

.

imho your theory on the 330 ft mark is near one full second off the mark,using the HSV performance tables below we can clearly see that a 13.7 Quarter Y series HSV auto makes for a 5.6 zero to 100kph time...dropping that 1/4 time to 13.3 with the LS2 engine makes for a 5.1 second zero to 100kph time....
My car has run numerous 12.1 seconds with the 330 coming up at the same 5.1 seconds ;) >i'm pretty confident the two cars do not have identical 0 to 100kph times.....
Below is an extract from the performance testing of a 2001 Porsche 911 Turbo..
( *Once within the safe confines of our test track, we fire up the instruments and make sure that the Turbo is as fast as it feels. And it is. Zero-to-60 mph takes 4.2 seconds and the quarter-mile whizzes by in 12.7 seconds. the only vehicle we've tested with quicker acceleration times is the Dodge Viper GTS ACR. Porsche might regain the title in 2002; by then the 911 GT2 will be available, with more horsepower and less weight than the Turbo. For more performance testing information and specifications,*)

Standing 1/4 times for an HSV LS1 and LS2 Clubsport R8 and 0 to 100Kph times

Performance M6
Z Series /Y Series
0-100km/h 5.2 /5.4
400m 13.5 /13.5

Auto trans
0-100km/h 5.1 /5.6
400m 13.3 /13.7

In summary I would estimate the 0 to to 100 Kph time of my car at 12.1 over the 1/4 to be close to 4.1 seconds...not the indicated 5.1 second at the 330ft mark :)

Too right that one would have to be sorted onboard I recon
Thats a nice rod in your avtar ,,Like to tell us more about it? pm if you think we might be highjacking this thread.

[LSX-438]

I whipped this chart based on the performance spreadsheet compiled by Dr Z on fordxr6turbo.com. Basically he did an analysis of 25 performance cars in the $30k to $60k range plus 5 additional 'benchmark performance' cars (porsche, lambo etc). Numbers are taken from motor or wheels magazines apparently.

Anyway i've plotted 0-100 vs 1/4 mile times below, and applied a linear trendline. To get some idea of your 0-100km/h time, look up your 1/4 mile time and track it across to the trendline and down to 0-100km/h.

Obviously this is rather simplistic but it should be reasonably close.

My truck covers the 100m dash in 19 seconds, but it's still quite a way off 100km/h

[MNR-0]

You are all quite right. 0-100m has nothing to do with 0-100kph. Referring to my last HPTuners log in my bolt-on 3.73 A4 I measured:

0-100kph 5.038s
velocity reached in 2nd gear at 5000RPM

From memory that was a 2.08 60' and 13.2s@107mph.

Sorry for the bum steer. Got confused between 100m and 100kph. :bash:

[cheffy]

I wouldn't know my cars never seen 100 km/hr before... :confused:

It differs for different cars and different conditions.. I would expect most 13 second cars to do 0-100 in just under 5 seconds... Ive recorded 4.6 seconds on the street...I personally think the old speed up the hill tests are more relevant due to the variables being taken out more but they don't do that any more.. The hill from bathurst to Blaney used to be used by Motoring News (could be wrong on the name).. Got photo's of various Journo's of the era taking cars up there.. (fencline of old family farm!!)..

[Elite SS]

I tried the 0-100 klm on the old faithful stop watch theory and it is very close to the qtr mile and Duncans scale :ForresteD"
This is based on my SS ute

Stopwatch 0-100 = 6.2 sec.
WSID 330 ft = 6.2 sec Average

The graph looks close but will depend on traction.
When the car was stock I was getting 6.8 to 7 seconds in the auto :lol:

SS3600 stall and ET streets at 24psi

GTech - Just did 4.09 with a soft flashed start - due to wheelspin still - need a sticky track. :(

I reckon it can go sub3.8s to 60mph and about 4.0s to 100kph if it would hook up. See what happens at the strip.

This was done in 22 degrees and with my quiet street exhaust.

baby cam, 3.73s and Yank Stall.

FYI

A couple of years back wheels magazine tested a v8 supercar and it could only manage 4.6 sec to 100km/h

Some of you guys are flying!!!

[a9x_hatch]

yes but v8 supercars generally run tall gearing i think 3.25 is the normal ratio and then they use a manual as well you cant compare that to someone with an auto 3500rpm+ stall converter and 4.1:1 gearing setup has alot to do with performance

[Gareth@Willall]

http://www.cars-cars-cars.org/0-60-Times-Calculator.htm

With just a guesstimate of FWHP and being conservitave with weight I recon that site may be on a winner :)

[Oztrack Tuning]

The V8 supercars suspension setup would stop it hooking up well at the start. they are supposed to only be able to do about 1.80 for 60 foot. Lack of traction not gearing. I dont know how accurate the 1.80 is.

The calculator on that page works well for my car at all stages of its development.

[STEVEO]

http://www.cars-cars-cars.org/0-60-Times-Calculator.htm
going by that it sais my car should do a 0-100dash in 4.2sec
going by this site which goes on 1/8th mile times it sais 4.3 sec....seems pretty close, might have to try a gtec at the track one day...
here the other site 2
http://www.wallaceracing.com/0-60_equation.php
its interesting it sais that the ferrari 550 marinello (spelling) does the dash in 4.2 sec, hehe
i know of someone who's street registerd v8 does (holden but not commo) 0 - 100 in 2.1 sec from the release of the transbrake button going by the data logger hehe, it also runs a wheels in the air pass of 9.4 too lol.

http://www.v8supercar.com.au/content/tech/default.asp?ind=M

According to the pdf. file download for a 2005 VZ Supercar the 0-100kph time is quoted as 4.0 secs.

1355kg with 620+hp If guys think they can better that in a 1700+ kg street car I want some of what they're drinking.

[Oztrack Tuning]

1650kg street car
Micket Thompson ET streets 24lb
3600 stall
3.73
4.3s to 100kph.

On a prepped track
post burnout with 20lb or less
the car should do under <4.0s

I cant stall it up at all or give it a full stomp at take off and still get 4.3s.

Many cars on the ls1 database quicker than mine.

Any car you see in the database with an ET <12.0s and with about a 1.65s or better 60 footer would go under 4.0s to 100kph.

But that is where most cars would start to see the back of a V8 Supercar.
Put drag tyres on them and drag suspension and it would be all over for many more of the cars in the database.

With my car its been fun seeing it get quicker from near 7.0s to 6.3s to 5.7 to 5.1 to 4.3. But under 5.0s we are getting close to the limit for normal street tyres. If our cars had 275s standard and didnt squat negative we would more easily see low 4s and better in street trim.

[Sid447]

Put drag tyres on them and drag suspension and it would be all over for many more of the cars in the database.

I think all they'd need would be a change of diff, as they are on a pretty low number (numerically).

Though yes agreed, specially prepared drag cars are something else.

Well I have to change my times now :lol:
With a new maffles edit the gtech read 5.1 on the cold semi slicks with wheel spin.
Got a 13.099 at WSID last wednesday with a 1.9 60 foot (with the drag radials.)
Next time Ill Gteck with the sticky tyres.
Oh and I dont have a stally set up and I have firm suspention.

[ACT_Cross8]

I did 3 runs with a GTech Pro in my Cross8 yesterday and recorded the following 0-60mph times:

7.34s
7.31s
7.01s

The one 1/4 mile run I did recorded a 15.50 @ 94.6mph.

I'm not sure how accurate the GTech is, but at least the 3 0-60 runs were consistent.

Gearing would play a massive part in this I daresay.....I wonder what a V8 Supercar pulls in 1st gear? Might make it hard to launch, coupled with what could possibly be a pretty narrow powerband to make 600hp out of 5 litres.

Tall gearing + peaky top-end biased motor = slower 0 to 100.

[NinetySix]

lets not forget the extremely grippy clutches they have

you cant really slip the clutch on them, its either engaged or not engaged... even v8 supercar drivers tend to bog down or wheel spin off the line when the green flag drops

[Oztrack Tuning]

V8 supercars wont go nose up and squat at launch. Their suspension would prevent that. So they would have trouble getting as much traction as a car setup for drags or even a car with standard suspension (that has taken care of wheel hop) -The V8 supercars are probably unable to launch at lowish revs because they are set to rev high and have a powerband only at high revs.

Also because of the gearing they would have trouble once they start spinning - the spinning would be happening at higher wheel revolution rates and make it harder to regain traction. (This is a good advantage of 4.11 gears)

Race circuit tyres would be shite compared to drag radials at launching - at least that is my guess. These cars if they only do 1.80+ first 60 feet at best would be giving away a bit at the start. Automatics with hi -stalls stay up in the revs and are always in the powerband so mid gear a car with much less minimal power would still be able to be in its sweet spot.

100k in 4.0s or better leaves little margin for error at the launch.

There would be nothing in it - but it sounds like there are lots of cars on this forum that would be next to one at 100kph.

Tall gearing + peaky top-end biased motor = slower 0 to 100.And since they change the diff gears to suit whatever track they're on the "0-100: 4.0s" spec on that site Sid447 mentioned is obviously a guesstimate to please curious fans who probably want to know how Skaifey would go against their mate's WRX :p On the tracks with a longer straights like Bathurst they'd be relying on taller gearing to get a higher top speed at the expense of faster acceleration off the line.

And like Oztrack said, the way the V8 Supercars are set up (suspension, tyres, etc.) for a circuit as opposed to a dedicated drag car naturally helps improve lap times while hurting say 1/4 mile times compared to a drag car, and vice versa for the drag car doing laps. Obviously you can't have it all in every situation without adjustments being made. Some production cars are great at being 'allrounders' in the sense they are great off the line and around a track. I've always thought of a 911 GT2 in that way.

[Tre-Cool]

i used my Gtech pro at the strip on wednesday and found it to be almost dead accurate, and the best launch\run for the night which got me a 12.575@110.95. The gtech said the 0-100 was 4.023 seconds.

Thats using 15" MT slicks and launching at 6K rpm.

[Oztrack Tuning]

What was your matching 60 foot time? and 330 foot?

Do you adjust the GTech so that it is level when stopped or level when accelerating? If so what do you put it on.??

Gtech is setup to read as low as possible i.e 0g for lateral or longtitudal (spelling) movement when stopped. With the new firmware for the Gtech Pro Comp RR you also have a pitch factor you can adjust too, so if the arse end sits higher up as mine does you adjust it accordingly.

I'll try and upload a screenshot of the results from another run later tonight when i fly back home. I accidently deleted the good one :-(

I took off the removable plastic part of the dash and drilled the gtech holder permanently onto it. as you will see in the pic.

[SV8VY]

Had low fuel today and did a 4.83 then a 4.77 acording to the gtech.Had some wheel spin and I tried to stall it to 1000.
Next time at WSID Ill give it a go with the BF slicks.
I will be intrested to see how acurate my old gtech is at the quarter.
