Choosing the £300 Donor car for my DIY Supercar: Prototype Ep2

Choosing the £300 Donor car for my DIY Supercar: Prototype Ep2



some of you watching this video might be thinking about building their own car it could be half way through building your own car or you've finished it but there is a problem and there is a mistake that you might want to avoid if he's thinking about building your own car let's find out what that is great my lovely shiny new workshop is already filling up with junk this is gonna mess with my OCD oh well it is temporary let's get this camera set up so here I am talking into the camera again it's a bit way because normally what I'm talking about cars I've got a pint in one hand and there's someone on the other side of the conversation so just bear with me I'm sure I'll get used to it anyway before we get into a mistake that you might make with your own personal bill if you're thinking about building your own super car I just want to show you this magazine okay back in 2031 2013 yeah this cars been sitting for that long gathering dust but anyway kit car complete kit car magazine they did a story on me so if you'd like to see some pictures and learn a little bit more check out their website and what I'll do is I'll try and I'll put in a will I'll put in their website in the end credits so you can look it up that's the magazine so if you want to get a backwater copy which you might be looking there might be some left then you can have a read and look at some of the pictures so yeah getting back to a classic mistake for anyone who is watching now and you want to build your own super car car whatever you will probably run off and draw some pictures completely understand that and I wanted to do the same but there is a problem you see it's okay for a large manufacturer to design a car you know artistic impressions that sort of thing that's fine they've got the money they can do it so when they draw the car they can design the mechanicals around and make everything fit let's just take a quick or what of me when you talk about cars wind and air are terms that normally only use when it comes to the aerodynamic aspects but with the vu Gani wider wind was the theme that would also draw the aesthetic lines of the car and reflect its character the wider is aggressive but elegant the creative team at Pagani Automobili merges the artistic and technical disciplines in their everyday work one man one engine skilled master mechanics individually handcraft each engine a commitment to mercedes-amg x' tradition of precision and quality the design of the turbocharger and intake system is a result of the drivability requirements and the turbocharged a v12 in the Pagani Huayra features the immediate throttle response of a normally aspirated engine Pagani Automobili is know-how in advanced composites has matured for almost three decades the characteristics of weight and stiffness of the composites used in production made the Pagani vehicles strong and light yeah so you can draw your car looks fantastic and then you've got 50 million pounds to have everything else developed around the design well if you're building your own car you can't do that okay so what might happen and I think this happens to a lot of people out there who try and build their own car is they engineer themselves into a corner what I mean by this is they build the body first they might make it out of foam and then the mitko fiberglass shell and then they try and figure out all the mechanicals but the problem with doing that especially if you're on a very tight budget is you'll find that your budget will escalate it will spiral out of control the problem is you have to then engineer every other part of the car you've got to make everything fit so you've got to try and make the steering fit you're going to make the engine gearbox pity that I make the pedals fit you've got to fit in it this is one of so many home-built cars and some kit cars out there have very awkward driving positions it's because they designed the body first and then they've tried to engineer everything in this ends up with a car that isn't very comfortable is it very fun to drive and it's prone to breaking down you can't fix it a whole host of problems now if you've got the money and the skills then sure by all means start with the body first and then engineer around the body for example take a look at to project binky and so you'll know about it don't search it on YouTube couple great engineers great guys and what the trying to do is get the mechanics of a silica gt4 four-wheel drive turbo I'm trying to get back to fit inside an old many company of BMW mini they all Austin Mini if you watch that you'll see what I understand about engineering yourself into a corner so I knew from day one I really couldn't just go out and draw the car and then engineer to the drawings I had an idea of what the car should look like it was more of a feeling if you know to me more of a taste there were certain design aspects that I wanted in the car which I did put into the car and but I thought I would design the car around the mechanics so I would build the car mechanically first so build it from the inside out and there wasn't got a fully running prototype do the body work around the mechanics around the driving position it will solve and it has solved so many problems one of the problems to solve was what engine and what gearbox should I use now if this car is designed or my end goal was for it to be mid-engined a v6 v8 in the back so I think the rear wheels that's what I wanted another goal I had was trying to build a car from one donor okay I couldn't completely do that because the original well the first doughnut is an Audi estate now if you look at the roof that's not an Audi there is a second during the car but we'll get into that in another video but for now we'll talk about the mechanics so the donor car of choice was an Audi I mean our DS are great I mean I love how do you I mean I've got I'm far like volkswagen audi group about gulfs and all sorts of siroccos and all sorts oh and I love the Audi Volkswagen brand very high quality great electrics fantastic engines now the good thing about Aldi especially on the larger cars like the a6 the a8 is there have and inline v6 3-6 v8 so the engine is right in the front of the car in line and then they have a trans axle axle gearbox which drives the front wheels or if it's the Quattro you'll drive the full meals and then the rear wheels this solves a lot of problems for me because when you pick an engine and you have to mount it to a transaxle to drive the rear wheels in a mid-mounted supercar you've got to figure out how the clutch works and how how you going to mount the gearbox to the engine this can cost a lot of money this is money I didn't have so the only sensible choice was to go with the LD gearbox combo which is already sorted the clutch and everything is good to go so before I started any welding the plan was to take the engine and the gearbox from an Audi the front part and then the rear suspension from the same car which would be the wishbones and shocks although I will put coilovers on later on and we'll get into that in another episode and what I would do is take the brakes drive shafts all that sort of see how great cables that's one thing and then I would bring the engine and the gearbox together now my first donor car that I bought was an Audi a6 2.8 normally aspirated now when I started this project it's got to be 2006 now I always planned to use the Audi a6 2.17 who is it was that car that I wanted to base my supercar on but at the time they were very expensive six seven thousand pounds and it's not worth spending that sort of money on a donor car so I bought an Audi a6 I think it was this c4 because they only a6 is c4 c5 c6 so this would be the c4 and I've got it 300 pounds it was a complete car it completely ran Drive and everything well not quite drove what happened was is the clutch pedal the the frame that held the clutch pedal in place had collapsed so you couldn't disengage or engage the clutch you could start a car and sort of get it into first and it would go but then you couldn't disengage so I bought that for 300 pounds and that was the first donor car now the donor car was looking for had to be manual and it had to be the Quattro this solves a few problems as well if you buy an automatic and you will try to take the energy especially a modern engine today if you try and put a modern engine that used to be an automatic and you want to use the original ECU if you want to budget which I am and you want to use the original ECU it's going to hunt for the automatic gearbox so for to start with a manual car to begin with it gets rid of all those problems now the Quattro has some favorite parts in it the rear and the front drive shafts are stronger the cv joints are stronger we'll get into that in another video but there's some other benefits and clutches a lot bigger stronger you've got bigger brakes on the sort of thing although on this one I ended up having to use BMW front brakes and we'll get into why again in another video we will pull up as the way I chose to do that and yeah we'll cover that in another video so I had been don't occur which was the Audi a6 it was a c4 2.8 normally aspirated manual 5-speed manual and is a Quattro I bought the original donor car and I put it into my garage and I stripped it to the seats out everything very slowly labeled everything all the electrics every the move was delicately removed and put into boxes and stored everything was documented photographed and written down and add notes in the computer the whole donut car was stripped and I cut the car in half pushed the rear of the shell out into my driveway I turned it upside down and then I could remove all of the rear suspension the rear Quattro system and the prop shaft that was sold on eBay because it would be no good to me so I managed to recoup some of the 300 pounds that I originally spent on the donut cart though it just cleaned up the rear suspension parts and that is what I used to build the rear suspension of the supercar so where do you stop you build you've got you down the car and you've taken engine out the gearbox and that's nothing where do you start and that's a tricky one this three main area is to start your build if you're gonna if you're thinking of building your own car one is the driving position got to get the driving position correct so seating another one is the wheelbase although I wasn't I didn't have a bodywork that would hinder my bill those were strictly by bodywork I did pick out a wheelbase the wheelbase on this car is virtually the same as a Lamborghini Murcielago it's slightly longer by 15 millimetres at the front just to solve a few steering issues that I had had to get the acumen steering right and I just had to push the wheelbase 4 by 15 mil and that's it but other than that the wheelbase on this thing is virtually the same same width and everything as a Lamborghini Murcielago first of all I marked out the wheelbase and I decided to start the build at the gearbox in fact split the build into two areas so the chef's see what visitors is up would be designed and at the back around the gearbox and then a second part of the build would be the driving position and that and then the two would come together within the wheelbase of the Lamborghini once I had the gearbox I did a wolf mock-up so I put the gearbox onto a crate and then just put the drive shafts onto it put the hubs on so I've just get some basic measurements ready to design the chassis let's take a quick look in my carriage and I'll just show you roughly how I set up the gearbox just to get some basic measurements so for a quick wolf mock-up of the gearbox from the drive shaft I just put everything on this crate and that worked well to get some basic measurements but this is never gonna work for any chassis fabrication the problem of God is the floor in this garage is not exactly flat and it's a bit high and lumpy in places so if you're gonna build a chassis it is absolutely critical to have everything completely squared and trim you cannot build a chassis off this floor and I would advise anyone doing that so I had to make a jig to pound some MDF this is fully adjustable and this was designed just to place the gearbox are you getting absolutely plumb and straight so I think they'll do for now in the next video we will go over setting on the gearbox and choosing the drive shafts and getting everything lined of style so they'll do for now see you the next
