Prawn and BigAls A3 Track Car

hahahahahahahaha

:iagree:

sadly, you're dead right :laugh:

****** door latch!

Anybody breaking a car got a drivers door latch they fancy sharing for beer tokens?
 
nah scrap it!!!
its not going to suddenly transform it into an unbarable car
and lets be fair any stripped track car can only be classed as comfortable when comparing to falling down the stairs
if it isnt needed for being road legal or going round track. bin it off!!!
 
The whole sound system could go without to much being noticed but I would like to keep the dash, it keeps things looking tidy and smart and it 's only a few kg's anyway.
 
As above.

Stereo goes, but the dash will remain.

The glovebox is handy for storing stuff and is still used lots - that stays

the door cards will be changed for something lighter, but will retain either fabric mesh door pockets, or something like plastic mini door bins to provide some much needed storage on long journeys :)
 
hahahaha. That's awesome!

can you find me a pattern with orange flowers though?

Seriously though. That plastic sheeting is to be my door cards, but retaining the top 'capping' of the stock door card.

the idae will be to have just a door pull in the middle, and some sort or net for storage. then all window switches moved to the dash.

The mirrors will most likely go too. they're probably a good kilo or more per side, with the bases and motors, and coudl be easily replaced with something a fraction of the weight for not a lot of money.

I was looking at a carbon roof, that would be good. Help a lot I think. On the other hand I was looking at a new Audi Cab. About the same price.:mad:
 
Well done on the trophy mate :)

On the door front I was looking at where can lighten mine the other day and theres supprisingly not much material that you can loose :(



Theres a couple of areas thag stoud out including the ally crash protection bars and a small area of pressed sheet steel that is in the corner

Looking forward to see what you come up with, was considering a bit of CF sheet but think am just gonna leave the doorcards in now

I agree with the weight loss difficulty with the doors. I think only very small amounts if we keep the winders. Personally I would keep the ali door bar. Firstly it runs at the opposite angle to the single door bar of the OMP setup, ties in the A and B pillars and ties in the two A pillars horizontally behind the dash. This is a track car, not a sprint car. Fractions of a second on sprints is not what this car is all about in my opinion.

Probably get shot down on that one.:D
 
I had my door apart last week too Stacey, you're right, it's definitely tricky!

my intention was to drill the hell out of just about all of it and see what happens!

The big flat runners each side would be ripe for some 25mm holes at 40mm centres, and the cross piece in the middle that looks like it's had crash damage (odd how they all have that kink!) will get attacked also.

I removed one of those alloy bars last week to see what it weighed, not as much as I was expecting really, but every little helps!

Yeah was just I didn't remember what it was like behind the panel and was rather disappointed at the little amount of "easy" weight loss there was to be had!

Looking forward to seeing what you do, cant imagine ill do much if anything in that area as my objectives are without a doubt on a lower level than yourselves

Another trip report!

Last weekend saw the years second CGTI event at Curborough. having had such a great day back in May, I didn't waste any time in booking on again.

The weekend started off well. i had almost nothing to do to the car apart from wash it and fill it with fuel.

A quick spanner check, and one replaced bolt in the splitter mounting:



And a new gearbox speed sensor, this time hidden away inside an OE protective pouch.



The old sensor went brittle due to heat exposure, and the plug snapped off. hopefully the OE heat resistant pouch should stop this happening again.

With all prep done, it was nice to have a relaxed evening for a change, and load the car in my own time, not rushing like usual:



With that done, Jardo and Luke arrived for a bit of a lads evening in. Tori ****** us an awesome Roast.



Jardo, being Jardo, didn't want a roast, so he had a pizza instead! brickwall

After several bottles of £1 IPA from Sainsburys, and some dodgy looking cider, Alarms were set for 0530 and off to bed.

We hit the road at 6am, it was a crisp morning, but it looked like the sun was going to come out later on :)

Jardo was trying his best to look butch:

But if we're honest, he looked more french:

10653783_1537082346506941_6362734908947347364_n.jpg


I have no idea who created the above pic, but it did make me laugh :lol:

We arrived at Curborough, and said hello to all the usual faces, Gurds, Ram, Alex, and the other ASN (Audi-sport) lads Joe and Daz.

After the briefing, it was time to que up:



10600406_1536897849858724_4930012438705083205_n.jpg


We started the morning on the new figure of 8 loop, but after just 2 runs we had a chat with the organisers, and they said that Gurds and I could just do the original B loop if we wanted to. This soon caught on, and within the first hour, everyone had switched back to the original B loop!

the figure of 8 is OK, but it just doesn't flow so well, and didn't seem to suit anyones cars or gearing. The corners don't work well running both ways through the cross over, the kerb positions arn't quite right, and it's a more dangerous route too, with one potential failure path leading into the trees, and another leading into the exit entrance gate and the spectators.

Back on the B loop, things were going well.

I had a careful first few runs, trying to get some heat into the tyres by being very aggressive on the outlap, and trying to pick the braking point for the hairpin. This seemed harder than last time, i spent most of the day trying to find that perfect braking point, and I only feel I got it right once or twice.

As you fly down the straight, the corner is totally blind and you can't see the turn in point at all.

If you brake when you first see it, you're already too late and you'll miss the corner. So typically, it's a game of dares, waiting it out until the last minute, then as you're on the brakes you tend to realise mid way if you've braked too early or not and adjust brake pressure accordingly!

I had a couple of good runs before lunch which felt sweet. Conditions were just right before lunch, with the air still fairly cool and crisp suiting the forced induction engines.

At lunch I had a quick look at the data collected so far, and was pleased to see that I had managed to shave 0.3s off my previous personal best, and that my last 3 runs had all been within 0.3s of each other, and ALL faster than my PB from the previous event.

Clearly, ideal conditions, and compounding experience were working well, as was the car :)

A couple of the lads had a bit of a track walk at lunch to take a closer look at some of the corners. Sadly, i missed this, as i was too busy enjoying a cheese and ham sandwich and socialising!


In the afternoon, the heat rose and many people started suffering from a lack of traction.

i found my front tyres had risen from 26psi, up to just over 30. I let them back down, and instantly found considerably more grip and stability. I think i'd somehow super heated them on one extremely aggressive outlap!

I took several passengers out in the afternoon, Joes mate Wilson had been blasting around in a 530i all morning, so was keen to see how it felt in something perhaps a little more suited to the tight track. He seemed to enjoy it :)

As a bit of a thank you for doing all the timing, Alex, Gurds and I all took Dex's friend Ruth out for a lap. I don't think she'd done anything like it before and seemed to really enjoy it. She's also the only person to have been in all 3 of our cars, so it'd be interesting to know how they compare from the passengers seat!

I took Ram out for a lap, which was great fun. He was telling me what he used as a brake marker for the first corner (discussed above). i hadn't spotted it, and Ram did say ''I shouldn't have told you, you'll try and look for it now''

needless to say, down the main straight, I was looking as hard as I could for this brake marker.

Could I see it?

Bol*ocks could I?!

by the time I realised I'd obviously missed it, it was far too late.
Que - much pedal stamping and locking up trying to scrub speed for the bend.

I JUST made it round the corner, coming inches away from an excursion onto the grass - Much laughing followed from both of us :lol: D'oh!

Enough text for the minute, a few pictures. I'll write more later.







Sadly, the award for 'best picture ever' goes to Gurds!

Alex's car was looking great too on it's new wheels. They really suit it very well:

Onto part 2!

Before lunch, I had the chance to jump in with a few other people for rides.

First, i headed out with Jardo in the worlds noisiest S3!

To give you an idea, here's a clip of jardo talking to himself on a later run:

[video]

My lap out with Jardo was quite funny. Rather 'loon on a hoon' early on. quite funny, but not the quickest way round, but it was his first time at Curby so it's always going to take a while to learn the lines.

As we were going round, I suggested a few different lines. using a bit more track, and mainly a wider line into the last corner before the straight. (basically repeating the kind of advice nige gives me :lol: )

Watching the video, it seemed to work, and Jarrods laps became better and better as the day went on. by the end of the day I think Jardo was pretty pleased with himself, and from the outside, he certainly looked to be going very well indeed. he's a very passionate chap, and i think this is reflected in his driving :happy:

10668984_1537384126476763_297715079132488925_o.jpg


I also got a chance to grab a lap with Daz20vt in his S3, also on his first visit to Curby.

14995227180_8386d34e18_z.jpg


Interestingly, the lap with Daz was VERY different to the lap with jardo. It was immediately obvious that Daz was thinking in much more detail about the driving, rather than simply going for it heart and soul. The result was an incredibly smooth and well controlled lap. Good pace, but less of the drama I had on my ride with Jardo.

The two ended the day with very similar times on average, but I believe Jardo had the edge on the day thanks to some impressive hooliganism before lunch netting him a very respectable lap :lol:

it was cool to be able to go out with other people and see their different lines and approaches, and even cooler to be able to offer advice and then see it put to good use.

I didn't get a lap out with JoJo, but we had plenty of discussions about tyre pressures, and my pressure gauge came to good use on more than a few occasions! Jo seemed to be having a really good day and was getting on great in what could be the worlds most immaculate low mileage early S3!

15188611071_327f0c6473_o.jpg


Fairly late on in the afternoon, Gurds and I were chatting about tyres. he seemed to be about half a second off the pace he had expected to have. We discussed various possibilities, and I suggested that perhaps the yoko A048's he had chosen to run wern't as well suited to the course as his other set of tyres - Toyo R888's.

Whilst the A048's are fantastic around a track, they do take a lap or two to warm up, and with a full run at Curborough taking less than 1 minute, there simply wasn't the time to get enough heat into the tyres to make them work properly.

A quick switch to R888's, and I let Gurds jump into the que ahead of me so he wouldn't lose too much time. I believe he went out and on stone cold tyres set his best run of the day! Clearly the R888's working very well!

it's a shame this switch wasn't made earlier, as I'm quite sure Mr. Singh would have knocked another chunk off his time with a few more runs!

This is still one of my absolute favourite cars!

IMG_2582_zps6b62caa1.jpg


At the very end of the day, in the closing minutes, Daz asked me to take his S3 out for a lap. I was all too happy to oblige, and jumped into the drivers seat to see what this 4wd lark was all about!

Jumping straight into a strange car with no warm up is a very bizzare feeling. Getting used to totally different power, brakes, and handling was quite a challenge on the 30 second out lap I had before the flying lap, but it was something I really enjoyed.

p1000755-jpg.40058


the weight disadvantage of the S3 was immediately apparent, and the lack of aggressive geometry changed the way it changed direction significantly. the brakes were very powerful, almost too much so for the tyres given the car was on standard road tyres. but there was certainly potential there, and with a fewsmall changes the car could be transformed quite a lot.

Daz was happy to receive the feedback, as it echo'd his own thoughts about his car. i think he'll be making a few changes before Donington, so I look forward to seeing how he finds it :)

15:56, and there was just time for one last lap in my car.

I headed out, and tried a smoother less aggressive approach, and actually had a really good lap. Not as brave or 'full on' as some earlier attempts, but very clean and incident free.

Video of that lap here:

[video]

That turned out to be my second best lap of the day, so obviously, somewhere between 'maximum attack' and 'gently does it' is the way to go as fast as you can. it's just a case of finding that balance as often as possible and using experience gained from being too aggressive / too cautious to find that sweet spot :)

Now, it's important to note, that the day is not a competition. it's a fun track day event, with data collected for participants to use for their own benefit and to monitor both driver and car progression.

That said, because everyone likes shiney stuff. Trophies are awarded at the end of the day for the 3 best times.

I'm afraid to say, on a CGTI day, it was an all Northloop affair at the top, with Alex, Gurds, and myself taking 3rd, 2nd, and 1st respectively :)

We had a little presentation and a group chat about the event at the end, and everyone agreed it had been a fantastic day!

Sadly I don't have a picture of Alex getting his trophy, as Daz's camera didn't take the shot properly, so here's a pic of Alex donating some Toyo Rubber to the circuit owners instead:

Another one to add to the shelf :)



An absolutely top day all round. well organised, well run, and fantastic company too!

Thanks to all involved. I can't wait until the next one!

Same as the last event Bill. I drove up on them and didn't bother with a wheel change at all.

Dunlop direzza 03G semis in H1 hard compound.

Not ideal in hard compound as they take some heating up, but seem to be working well enough for me :)
 
fantastic summary of the day mr prawn!!!
i cant believe not more people do this?
certainly looking forward to the next time i will defo make it!!
still havent had a passanger ride with you at the wheel but being the understanding gent that i am i thought id let you have some timed laps ( though at that point you still had a first place time)!!!!
thanks again for takin the bus out, having your opinion with your experience is invaluable to me at the start of my track car build/thing
you're a top man nick and your pitlane popularity proves it!!!
cant wait to do more track time with you and big Al!!!

i wanna try to get my new wheels, tyres, fmic and front camber sorted before though!!
the saga continues!!
 
reading prawnies track day and curborough type fun days, reminds me of years gone by in my old 16v jetta.... Happy days, but I feel so much older now reading young_uns treading the same path and enthusiasm..

Well done prawny..

On the front door, window winder subject, I think a look at a manual system as of old would be challenging. Or perhaps a rope and pulley system using plastic marine stoppers.??? All pie in the sky, but could be worth consideration. As Nicholas said, get rid of motors, door cards and mirrors. Replace with fabric and light weight ebay mirrors. Has to be a few kg's there and don't forget the easiest of all. A chicken salad the night before with a glass of water and a Continental Breakfast.:whistle2:

Curborough looks like a hell of a lot of fun, I'm definitely going to have to make it to one of those next year. Nice write up too Nick.

I'll happily rant all day about how important keeping weight down is, but I say keep the electric windows. Every time I've picked up window mechanisms I've been surprised how light the electric ones are and how heavy the manual ones are. The electric ones area heavier, but really not by much. Manual windows are also a pain in the backside when you're harnessed in and the winders are inevitably that little bit out of reach. I wouldn't have said it's worth the hassle to loose them really. Not unless you go to a very basic pin-in-a-hole type system to just lock the window in a couple of pre-set places.

Replacing the mirrors sounds well worth while. With the stereo, could you just keep front door speakers and a small 2 channel amp hidden somewhere with an 3.5mm jack to play from your phone? You'd probably loose over half the weight, and still have some tunes for the occasions when you want it. That's pretty much my plan if I do strip the Scirocco right out.
 
The electric windows STAY. My last post, if you can read between the lines, was a !WIND UP !.
 
BigAl you are totally right!!!
tbh ive had a bit of a change of heart
theres barely any weight there and the electric windows and mirrors are sooo convenient.
im going to move my switches to a panel where my double din used to be so all i have are handle and a door pull.
i dont wanna hate driving it even if it is only to get to the track
and as with you guys im at a point where half a day on the car might lose me 1kg or so
you 2 more so!!
let nick lose with his hole saw kit!!!
 
I think we're a little way off hole saws (or even half saws :laugh: ) just yet!

Plenty of weighty crap to remove before I get into that detail!
 
Why would you mount your switches where the radio was?

I know you're a short **** Daz, but surely you won't be able to reach them when you're strapped in?

I

That's where mine will be going also.

Door cards are going to be replaced with a flat panel below the top 'capping' part.

Daz currently has the stock switches mounted into his custom door cards, and whilst he's done it well and they work, it's shown me that it's not how i want to do mine.

The long term plan is to replace the centre trim panel where the radio was with a carbon panel, housing new window switches. On / off switches for hard wired in car cameras, and a semi permanent mount for some form of data logging device, which will probably be an android phone of some sort hooked up to an external GPS.

ive made a custom carbon fibre rod which will be mounted to my door cards for easy access and ill use these to prod these switches

you are defo right about the cards and switches
glad i did them for a base though
i want only pulls and handles on the card
and i dont want them having to protude like they do so thats going to take some investigation
will also have to findmore appropriate switchs as the oem ones dont mount nicely
 
Check out car builder solutions. they do some half decent looking switches for about a fiver each. Flat panel mounted. nice and simple.
 
what about wiring
worst one is the mirrors switch tho
yours are going right?
 
Not adjusted my mirrors in YEARS, so the switch / motors can certainly go!

Will probably look and see if the whole mirror / base can be removed and replaced with something smaller and lighter.
