GTR to Claim 0-100-0 World Record?
Discussion
Paul,
I'd agree with you that it would be very hard for an Ultima to take the record. However, my Mk4 wieghs in at 950Kg with a full tank of fuel, and the fuel weighs about 70Kg. It has regular road going bodywork, so it's a lot heavier than it needs to be. I think that I could quite easily get the weight down to 800Kg (with minimal fuel). As it's a race car, it's geared for acceleration rather than top end (you very rarely exceed 150mph on most circuits in the UK), so it's probably fairly well set up to hit 100mph in pretty quick time.
All I need is a slick sequential gearbox (about £10k) and some nice carbon Kevlar bodywork (another £7-£10k). I'm taking donations if anybody wants to see their favourite marque take the world record
Of course, you'll all getyour names on the car.

I really don't see what the big deal is. We should just ask Kurt D. to contribute his car to the test! Its already fitted with a turbocharged 1000+hp that he can probably crank up to 1300-1500hp if needed (no joke!). However, it would help to mount a set of 10" wide fronts to take full advantage of the front brakes. Now we just need to figure a way to keep the driveshafts and gearbox from being trashed. Oh, and we'd have to do a 4130 chromolly tube frame chassis with extra reinforcement and possibly a little anti-squat and dive geometry thrown in. Hmh...maybe we should be talking about a 2000hp big block! Its all just a monitary issue really.

Might as well put in my two cents, or do you say pence?
For a ONE time stop of 100-0, any brakes will work equally as well for that short duration. All you need is the bias balanced properly between the front and rear, and no lock up.
The most important factor in the equation is the tires. The more sticky, the more quicky!!

The 50k TVR braked from 100-0 in 4.9 sec, I recon an Ultima should be able to beat that.
My car weighs 1000kg with full 75litres of fuel weighed on monday at goodwood (full screen, hood, stereo etc.... no poof jokes please James!
).
It has 526Bhp so that's 526BHP per ton wet. I know the Mac F1 has around 550BHP per ton but is that wet, I thought it was dry if so mine works out at 4BHP per ton more.
With just the one gear change to 100mph from (1st to 2nd i.e. straight back) it should be fairly good when compared to the F1.
Therefore I still think it will depend on the braking, if we can beat the TVR and get down close to 4 sec from 100-0 we stand a chance. After all the Zonda came close

Interesting Fact
The R500 Caterham braked from 100 - 0 in 3.44 sec about 1 sec faster than anything else
Last year the lighter Caterham Blackbird which is much lighter took 4.38 secs.
My money is on some Avon ACB10 ( a road legal cut slick) but the ultra soft compound for hill climbing good for 5 miles

Reading the autocar article where the R500 achieved the record, and some interesting facts are evident.
Zonda hit 60 in 3.7sec then 100 in 7.52sec, breaked from 100-0 in 4.05 sec.
The 911 turbo did 100-0 in 4.28 and the lambo 4.41.
As the Lambo weighs 819kgs more than my can-am I expect my big brakes to stop me faster than that, hopefully less than 4.1 sec.
So say 100-0 in 4.1 sec reaction time of 0.3 sec, that means the car has to do 0-100 in 7 sec's or less.
Hmmmm it's possible as if we take the Zonda, 3.74 to 60, an Ultima should be able to do 3.2 to 3.3, that's around half a second to 60 advantage, should be able to gain more ground from 60-100 with the extra 100bhp per ton advantage.
Lets call the 60-100 advantage as 0.3 sec we have a 0-100 time of 7.52 (zonda) less 0.8 sec thus 6.72 still slower than the Mac F1 but hey we just beat it on the brakes and did a 11.12 sec 0-100-0.
WE NOW HOLD THE RECORD!!!!!!
I'm also available to do you accounts at a reasonable fee.............

Only one way to find out ally. As the ying goes:
Money talks, and bullshit walks.
You realise that something like 2 or 3 hours have been spent typing all this speculation, and it would take less than 12 seconds to find out.
We should all get our cars out to a nice smooth bit of tarmac, and see who can beat the record (if at all).

We could use your driveway Jim?
For reference: here are the performance stats from the Autocar Road Test for the McLaren F1:
0-30: 1.8s, 40: 2.3; 50: 2.7; 60: 3.2; 70: 3.9; 80: 4.5; 90: 5.6 100: 6.3secs
1st Gear: 65mph; 2nd: 95; 3rd: 125; 4th: 150; 5th: 180; 6th: in excess of 230mph
Standing Qtr Mile: 11.1s/138mph
Standing Km: 19.6s/177mph
30-70 through gears: 2.1s
Here also are the incremental times for the F1LM's 0-100-0 former record (see www.mclarencars.com):
0-10: 0.9s; 20: 1.5; 30: 2.0; 40: 2.6; 50: 3.4; 60: 4.0; 70: 4.5; 80: 5.0: 90: 5.9; 100: 6.7; 90: 7.3; 80: 7.7; 70: 8.1; 60: 8.5; 50: 8.9; 40: 9.4; 30: 9.8; 20: 10.2; 10: 10.7; 0: 11.5sec
Perhaps Autocar or similar mag might be interested in covering an attempt on the record and might even cough up some dosh to help...
Great to see the cars at Santa Pod. My two children got very excited - now I have to build my own.
Great to see the cars running - shame about the CanAm breaking on the day

My can-am only broke because it had the wrong (weak) drive shafts in it due to a mix up.
It pulled a 11.4 on the first run with a poor start, when I got the start right it destroyed the CV joint.
Good to know that my car is very close to the Mac F1, almost certain with the right start it will go below 11 sec, maybe we're in with a chance for the Title!
Will we try again, word bears and woods mean anything?

As a matter of interest I was in conversation with Steve Sutcliffe from Autocar about the 0-100-0, done about 4 wks before it appeared in the mag, and they would dearly like to feature an Ultima in the test. So, if any of you guys out there gets a time that looks like beating the R500 I'll set up the feature. Money, mouth, where, put, your and is spring to mind! MC
OK Several 100-0 noughts were tried I managed a best of 3.8 secs on the stop watch, which was held in my left hand will gripping the steering wheel manfully with the right.
There was too much rear bias so this could be improved.
Now a limited slip diff, a motec m48 and kinsler injection and the record will be mine

May beat you to it as I know that I can get less than 7.5 sec to 100 (acheived and timed in the 8th mile at the pod on my first attempt!)...... and now I know how quick the car can stop
That's below the record, now we just have to do it officially!

Maybe the club could arrange a test for Ultima owners using proper timing gear, would make a good article for the site.
We could use G MAN's airfield that he seems to have access to

Then you have to take into account reaction time of getting off the gas and onto the brake, and the time it takes to reach maximum braking etc., so it isn't just a case of adding the 2 times together.
You may also want to rig up a big light on the dash to come on as you hit 100mph too
I always said I thought it would be decided on the brakes.
I think though that we have proved that an Ultima is in with a chance, having now proved (officially) the car accelerates quicker to 100 than both the R500 and the Zonda all we have to do is match the braking.
All pipe dreams until we time the cars on official accurate timing gear through the full cycle.
It's been fun so far though hasn't it G MAN
