GTR to Claim 0-100-0 World Record?

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
I always remember the standing 1/4 mile done by Jeremy Clarkson, the JPE Caterham was dispatched by almost everyone in a couple of secs.
Ultimandy may be ready but I need a SLD at a minimum quickly !!!!
I also think that the R500 runs on 13" rims 7" at the front and 8.5" on the rear (approx from my poor memory) so the contact patch - rubber on road is much smaller than ours . From my judgement Caterham JPE V Ultima GTR, the Ultima is a much faster car and has better brakes. I know Dunlop are doing some type B road legal race rubber in 18" next year, this will guarentee an Ultima positive result

Not aware of any lightweight bodywork options.
I know of a carbon fibre bodied car that the factory have aquired, it was made by a company as an R&D excercise and to prove their skills.
They claim that it actualy ended up heavier as it required a lot of filler and paint to acheive the level of finish that they get with their Gel coat!
Testimate to the factory quality that even a specialist firm spending over 100k couldn't improve on the standard offering!
To get the weight down significantly I think you will need to start fabricating things in Titanium.
My personnel aim is to prove a standard high spec car can beat the time not one with sticky tyres, lightweight bodywork or any other tricks.

I have thought of specing a chassis in T45 steel, this is half the weight and 2X as strong as mild steel
I have a roll cage made of one
The factory do a light weight fibre glass body but the finish is not as good in gelcoat.
So what we need is a T45 chassis with a light weight fibreglass, all alluminium engine with titanium parts,
Motec launch and traction control, Dunlop MSA Class B race tyres, trick gearbox gear for 100mph in 2nd and SLD and we are there !!!!

Slicks won't work as they will never get enough heat in them unless they are hill climb specials or have tyre warmers. Tyre warmers will have to be added to the list. Also your times last week included reaction times. On the 0-100-0 runs they can't use this, its just start point time. Therefore I would use the santa pod reaction time at the lights as the break reaction time. That should save 0.7 of a sec.

I already have a gearbox that gives me 100mph in 2nd, in fact it will do 105 at 7000rpm and I don't think traction control would make my car faster it doesn't really suffer from traction problems despite the 'small' 315 Goodyear tyres.
And as I said before I would rather not start down the 'sunday specials' route as this will be less of a reflection as to what the car can do, and more of a reflection as to how much money you can throw at it. Imagine if Maclaren decided a couple of turbos would be nice!
A well organised day timing different spec Ultima's will answer the most common question i.e. how quick are the different specs and models and show that an Ultima could hold the record.
I seem to remember someone else asking if a test like this could be arranged via the Club site. If enough show interest maybe this will be arranged.
Anyone else up for it?

As I started the T45 chassis thing ....
The only car I know with T45 chassis, is the TVR Speed 12.
I have a Honda S2000 with a T45 cage in it and it is very light and strong... While it was being fitted I asked the difference in weight and was given a pipe made of mild steel and one of T45, the T46 was much lighter. This is subjective ..
Presently I have heard of no T45 chassis option just my desire

Recindling the fire a bit.
After looking at my slip from my two runs down the Pod I realised that I was hitting 100mph on the 1/8th mile and thus I had an official time of 0-100mph for my car.
This time was 7.52seconds on my first run (not a perfect start by any means).
Come on lets organise an event, not just for the record but as a benchmark for each different spec and type of car, I know there are faster cars than mine out there!

Hi
Do you think this will come up in production
and against wich prices ,
i think it will cost more if they would
Miraz said: The current factory demonstrator (the red one) has been fitted with the lightweight bodywork.
Ted was claiming something in the region of 40kg's of weight saving.
