Looks incredible, what have you got planned next?

tidy this up and then will get working on the GTT

[andygtt]

Its going to remain lacquered carbon.... later Im considering tinting the lacquer blue, but for the moment Im going to live with it as it is

Well this has helped perk up an otherwise dull afternoon!

I'm glad I only stumbled across it today, as getting to see the (mostly!) finished item is awesome. I know having to wait for updates would drive me mad!

Kudos, look forward to seeing some videos when you've got the car running as you want it. Do you reckon you're at your 700bhp/t now?

Cheers, I'm certainly close to that figure... Engine def has loads to go and am going to push it a little further in the future.

I have M800 GTT on retention just incase... Rings quite nicely as well as I run an M800 ecu :-)... Guess we will have to see!

[andygtt]

So thought a little update should be done.

I discovered what my fuel pressure issue was, one of the pumps was getting red hot on idle, so I swoped it out thinking that was the failure, the other one then got red hot, so I swoped the wiring around as I'd done that at the same time as swoping pumps, no change.... Clutching at straws I swoped this pump out as well, again no change... Pumps are located under the middle of the car.

I then dropped it on the ground and removed the fuel filter (on the rail so easy to get out and 2 min job) low and behold full fuel pressure and quiet pumps.... Filter was blocked and probably the easiest part on the car for me to swop out... What an idiot lol.

Anyhow car is now staggering, power is simply endless, the harder I drive it the more it delivers. It's all been worth spit and some... Going to lemans classic next week then a will refine the car and it's setup ready for silverstone on 8th sept.

Here are some pics of it at my wedding 2 weeks ago.... The blue car is a friends that's similar spec engine wise to mine running an M800 motec ecu as well.... This picture represents over 1300bhp and around 2100kgs :-)




A friend also played with the pic to look like scale trip cars ( I rented a 6lane scaletrix Grand Prix for the night as it was also the 24hr leman and would have been rude not to)

A friend did a short video of my car at le Mans... our camp site has a garden party with a little car show which ends in a rev off... because my car goes on track regularly it is pretty quiet compared to the ferraris and V8 monster cars that also attend so I'm always blown into the weeds... I decided things had to change and activated the advanced functions in the Motec ECU and used launch control during the rev off.

I was quite the crowd pleaser

Stunning and congrats! Whereabouts are you staying for LMC? I'm there Friday - Monday and would love to have a drool over the car if you didn't mind? I'll bring a bib!

sorry i didn't see this till today, i stayed at a chateau a few miles outside the circuit.

[andygtt]

Last week I took the car to a garage that has access to a track and we swopped springs around and tested it on track until we found the perfect setup for my car, its now compliant and comfy on the road and well controlled on track

of cause while we were messing around with the shocks we had to re-setup the ride heights and check the corner weight's and now with 40Litres of fuel its a solid 100kgs lighter than when I started putting it on a diet

cars now a genuine 700bhp per tonne

[andygtt]

well my other wheels and tyres are close to 10kgs lighter, and I have a few alloy panels under the car to replace with carbon.... Im also making my own design of seats for the GTT and they will be going in the noble as well.

But in truth I also have a little weight to add, like around 2kgs for new carpet over the tunnel, so the only realistic way to get under a tonne is to weigh the car with only 10litres of fuel in lol

Plan is to drive the car a lot more and get on some track days

[andygtt]

Sorry hadn't spotted your question, I was doing some mods to a spare rear clam I had and as such started to research making moulds etc etc... I then spotted people making moulds from materials that were good enough to make carbon parts from and I then focused my research on that, bought materials, watched some online videos and started making parts.

The material suppliers did think I was totally mad going straight into making a full rear end, but I tend to not do things by half... I enjoy a challenge

[andygtt]

So following lemans I decided to get the car health checked on the dyno and maybe squeeze a few extra ponies from the car... Had my friend and tuning guru Sam at torque developments do the mapping and we might have squeezed a few extra ponies out of the car so it's now 'solidly' over 700bhp and 600ftlb.
It's now 100% a 700bhp per tonne machine :-)

I also decided to activate the traction control and full throttle gear changes, had a few gremlins with the wheel sensors so the traction control isn't yet usable but the full throttle shifts are awsome.

Did a track day on the silverstone GP circuit a few weeks back and took some front and rear footage then I combined it with the telemetry from my ecu and posted a little one lap video using the rear camera.

Good lord, that car is a beast. Have you got any figures for it such as 0-60 and 0-100? I know it's kind of irrelevant in day to day driving but it would be interesting to know.

it is a beast for sure, but its a very controllable beast and dare I say, easy to drive

Not got any proper performance figures, but I do have accurate ecu data logging and while testing the launch control and traction control on a cold but dry night I did do a launch but it wasn't set up right and I had a huge amount of wheelspin up to around 50mph.... I checked the telemetry and it had achieved a 3.4s 0-60... so imo its sub 3 seconds to 60mph for sure.
On track my telemetry shows on one straight I did 60-141mph in 5.8 seconds, stick the 2 bits of data together and you 0-141mph in 9.2seconds.... given that the 1200bhp veyron supersport was independently timed as 0-150mph in 10.1 seconds and the new P1 is 0-147.5mph in 10.2seconds... so even with a poor 0-60 it seems I'm pretty much a match

Of cause this is all unofficial with me stringing together 2 bits of logged data so very back of fag packet...... but what I can say is I once took part in my Ultima in Autocars 0-100-0 challenge against zonda etc etc (2002) and I did an officially tested 0-100 in around 7.4 seconds (faster than the zonda) and my noble is much much faster than my ultima was

[andygtt]

The weave is lined up when I lay the cloth in the mould.

I bought a software that allows me to put a video in a video so I managed to cobble the front and rear go pro footage then overlay the ecu telemetry.

[andygtt]

I had noticed there was a few pictures in the article of my car...

brakes were not glowing, thats simply the sun shining on them....

I literally finished putting the car together 10 mins before leaving for this track day... Id remade the entire tub so was a major strip down right to the bear Chassis and car hadn't turned a wheel in 5 mths before leaving so I had teething issues lol... I only got 3 very slow laps with no throttle.

At least I made it though, many (including my wife) thought I had absolutely no chance lol

After just finding this topic this morning and being astounded by this car I then saw it at the autosport show when I got there! Even better in the flesh.

Thanks, most people thought it was wrapped.... I overheard a large number exclaim it was a wrap as they could see the edges and joins lol
It wound my missus up a lot and it was entertaining seeing her storm over to put them right lol

Hi Andy

I have just started reading your modification (well it's a build really) thread on your Noble.

I have a few questions from the first page, so I apologise if you have already covered them in later parts of this topic.

On your fuel tank, can you tell me what you have used to seal the lid of the tank to the body? Fuel plays hell with seals in my experience.

I see you have some hoses in the tank immersed in fuel. Have you had any issues with the ethanol in petrol attacking them? What are they made of?

The reason for my questions is that I am thinking of building a large swirl pot with immersed pump, filter and regulator on my Ultima to simplify the plumbing.

Paul

Hi Paul

I had an issue with the first rubber I used to seal the top, it was bought as fuel proof, but turned out it was simply fuel resistant... it disintegrated and car smelt of fuel.... I then replaced it with 'proper' fuel resistant rubber and its perfect years later, i put a sample in a jar of fuel and its still intact (after first failure I wasn't so trusting lol)

The fuel hose was bought as submersible fuel hose so is meant for the job... I run 2 lifters (which have sock filters on) good for over 1000bhp direct into the swirl pot in the tank, I have a hole at the top to release the pressure so that they are always free flowing but it does give a small amount of pressure in the pot... I had to direct it as the overflow of fuel was actually quite noisy.

I then run 2 044's outside the tank both fed by the huge Pot... then into a fine aeromotive filter and then the rail.

Like the Ultima packaging was a key factor in the way I designed it all.... I also wanted it to be bullit proof

[andygtt]

Small update... over the last year I have been designing my own seat, its my own shape so its been quite a lot of work and i finally finished the buck around a month ago and I started making moulds.

Pulled the seat a little over a week ago and hurriedly upulstered it in leather myself much to the amusement of my skeptical Wife

Its turned out extremely comfortable, for me. I tried various 'expensive' seats at the autosport show that inspired me to make my seat (as I loved how comfortable and yet supportive they were but couldn't afford the £2k + price tags lol) and I came away very pleased

end product





out of the mould and bonded together, its a 2 part seat and extremely stiff... much stiffer than the selection of different cobra FIA seats I have including a carbon one.

[andygtt]

I don't have any pictures during the making of the buck... it went through various stages of fiberglass with copious amounts of filler,I even took moulds from some of these stages and the end product was a cut and shut from a number of these stage.

here is the final buck that i took initial moulds from

[andygtt]

Only minor jobs to do on the noble now... Got a couple of things to make in carbon, wing uprights, interior bits.... Started to recon the brakes, new hard lines and braided lines and new master cylinder... Searching for an upgrade for the engine coils and going to fit better injectors then get it mapped for these, unlikely to search for more power (although I have always had M800GTT on retention just in case lol).

So other that video clips and pictures there isn't going to be many interesting updates to this thread lol... As has been pointed out, I have started a new project to keep my brain working :-)

[andygtt]

I just lacquered the car so it's raw carbon.
