Quote from BlueFlame :Alex, you're a fool, how can you talk about entertainment and excitement and boring cars when you drive a Lada. Actions always speak louder than words Alex, why act one way and talk the other. You make no sense. I'd take a Golf GTi to a Lada Niva any day.......

It's a Riva not a Niva, and it's anything but boring driven quickly. It may be a lot slower than the Focus cross country but it is a hell of a lot more fun, even a car like the Focus is too capable to actually be driven fast on the road. It's not about driving a fast car it's about driving a car fast, and the slower the car the faster you can drive it safely on the road.

Quote from gezmoor :*totally misses the point*

Who cares how fast a road car is from point to point? High power front wheel drive cars are cheap, very fast and generally extremely boring. Driving such a car quickly on the road results in silly speeds, far better IMO is a car that can entertain you at a more sensible pace on a back road.

When you go beyond driving quickly and begin to drive a car fast a rear wheel drive car rewards you there's nothing like throttle steer, the faster you drive the car the more precise your control over the car becomes and the more rewarding and satisfying it becomes. A front wheel drive car does not reward being driven fast in the same way, driving one fast requires skill but is mainly about planning in advanced and controlling understeer, the harder you push the less control you get.

'and the season can't end up with [everyone] being one second behind the Brawn cars' errr... yeah Brawn obviously aren't entitled to win the Constructors Championship.

Equally Jenson is currently leading the WDC, presumably Briatore's contract to manage Button, choose his team and reap the prize money has run out and he's a little bitter?

Just sit down and do it, getting through coursework is far easier than revising/learning something, just treat it like a job, start in the morning and you'll probably be done before lunchtime. Don't start planning to do it in 20 minute chunks it just doesn't work.

Currently I've got an assignment due in Monday and a car that needs a clutch in it to hand in said assignment, I'm certainly not distracted by TV atm...

Quote from duke_toaster :Couple that with a ban on any device that modifies the power output characteristics (adjustable rev limiters, fuel mappings, adjustable turbo pressure limits and this launch map bollocks) and you would have a good engineering test bed. With appropriate measures it could be compatible with cost control, by allowing independant teams to buy engines at a fixed cost ...

So basically ban innovation and future technology development from motorsport?

Don't take the piss Chinese engineers make some brilliant breakthroughs when they aren't copying the developed world, like the oversize Formula Student car (with shocking welding), the touring car with the exhaust exit out of the front bumper and the scrap metal F1 car.

F1 cars still have nearly 6 inch sidewalls, which is huge and would have extremely adverse effects on a car that isn't designed around them or without having relatively extremely stiff sidewalls/special construction that bares little resemblance to production cars.

Quote from gezmoor :
Also seen it mentioned that an F1 tyre only weighs 10kg. Could it also be that a 13" wheel with 325/45 tyre actually weighs less than say an 18" wheel with a 325/25 tyre on it?? Are 25% aspect ratios even possible??

Certainly not, the tyres are far heavier than a magnesium wheel.

I think a lot of damping is still done through the tyres and the stiffness (or lack of it) in the large sidewall is significant and the extreme deformation experienced by such a large tyre must be pretty critical (and presumably beneficial) to the design of the car. Having said that have the teams actually got any choice as to what size tyre they want to run anymore or are the tyres the way they are simply because that's what is specified in the rules?

Quote from brt900 :
does anyone have any links to some lcd displays i saw one in a book a few days ago but cant remember the name.

Loads of companies make LCD displays, Pi, Motec, AIM, Stack, Momo, 2D, GEMS. They all come at a cost of between approximately £1000-3500 for a basic display.

Most are not a road legal replacement of your dashboard though because they do not have an odometer, or any of the useful indication lights (lights, indicators etc.). The cost of adding these would be enormous so you'd have to keep the original speedo.

There are a few LCD displays designed for rally use that are fully road legal, the cheapest LCD displays are about £500 (try Race Technology) or Stack make an analog tachometer with LCD readout strip in one neat enclosure for about £900, and I think they offer a road legal option.

Quote from DarkTimes :
Edit: I know this question might seem a little petty, but there could be an instance where only eight cars pass the 90% mark (and become eligible for points) and two of them crash into each other at the end of the last lap, so there must be a system to decide the scoring.

I think to finish a car has to cross the line after the chequered flag though, simply doing the minimum distance to score points won't count.

The best track days are open pitlane ones, typically start at around £120 for airfield circuits or around £200 for race circuits for a day with about £20 per extra driver, you can get half days/evenings for less. It would be much cheaper to either drive your car from Portugal or buy an old banger in the UK than try and hire something for the day and you don't have to worry what state you leave it in

They're nice cars but I'd expect to get something in good condition for that price. They tend to last but obviously a car that has been thrashed all its life is going to be a dog, so steer clear of M3s/bigger coupes for that money (you do get some). If it hasn't been abused to much then typically it's just dampers and bushes that need replacing overtime and the bearing in the alternator can go (costly). Overall though they're easy cars to work on being a nice open front rear layout clutches and diffs are not big jobs.

Fat, ugly overpowered front wheel drive thing can't really compete with a proper car.

Quote from Nathan_French_14 :
The engines are strong on these. Seing as this one has had a 1.8 fitted, it may have replaced due to failure of the original.

The later E36 316s had an 8 valve 1.8 engine.

Not really, just means that for the events after this weekend they need to get the tunnel problem sorted to be granted a licence - although, I wouldn't particularly want to crash and go down the drop into the tunnel..

Hope so my Dads racing there this weekend

If you don't have jump leads and refuse to bump start then you are broken down?

I always carry spare fuses (should really carry a relay as well), a torch, a roll of tape, a foot pump and a few spanners and screwdrivers. It's very important to check you're jack works and you've got everything needed to change wheels, I had a flat tyre in the Focus once returning from Snett, when I found there was no wheel brace in the car having just about managed to make it home stopping at every services to fill up with air and not being able to find a single place selling a wheel brace I found my Dad had firstly used the horrible spare wheel brace to change a wheel in the garage and then left it on the floor, could have killed him!

Other than that I've just got a fire extinguisher, which every car should roll out the factory with as far as I'm concerned. It really is worth having one to hand but worrying how few people have one to hand, I remember a car next to ours catching fire in the paddock at Mallory and quickly finding out that there weren't any obvious fire points in the paddock, then realised we didn't have a fire extinguisher in the truck because the last one had been used (even more reason to get another!) and with the plumbed in extinguishers in race cars now nobody can actually fight a fire on anything but there own car, by the time somebody had found a weak and feeble water pistol the fire had grown beyond it and we had to wait for the circuit fire car. In this rather sorry scene a bunch of racers had failed to extinguish a small slow burning easy to put out fire that would have undoubtedly burnt the car out had it been anywhere other than a race track, a single small hand held extinguisher would have had it out in seconds so long as it had come quicker. Always have it to hand, if you can't reach it from your seat then there's not a lot of point in having one, and for gods sake don't put it in your spare wheel well.

Quote from morpha :Because it could get unburnt fuel into the catalytic converter (if the car has one, obviously) which is bad... That's pretty much all the info I get from my cars manual. It's just one of them "don'ts where you don't need to know why" for cars with catalytic converters.

I guess it could ignite due to the high temperatures later and kind of blow the cat to pieces or maybe a film of whatever doesn't evaporize from the fuel sticks to the filters. Anyway, if your car's manual says don't do it, just don't do it.

I've totally ignored that gem that newer cars come with (though I've still got the very original sticker on my windscreen instructing me of this). Cars with a cat bump start fine, I have no idea quite why they're going to be damaged and anybody who phones a breakdown service rather than bump starting because they can't be bothered to push the car out of a car park or are frightened it'll blow up is a moron. Bump starting is fine and so long as there are a few people around I'd always choose to bump start rather than jump just to save time and to save lugging jump leads about (if you can find someone to jump off you can find someone to give you a push).

A very good move as far as I'm concerned, keep the cars much more standard like in the good old days, hopefully the WRC will become a bit more relevant to the production cars again.

Quote from DHRammstein :
Anyways, ajp71, do you recommend those brand tires for an american car? Regardless I'm gonna start looking into it, and I'm gonna call my buddy, the dude that owns the shop that built a lot of VW VR6, he raced for years, dunno why I didn't think of that. But I also figure this place would be a good start too, there "must" be a lot of real racers/tuners around here, with pretty badass street cars of their own.

Your car should have been setup to suit performance radial tyres, anything should work fine on your car, just get the harder compounds of these tyres if you want them to last on a heavy car.

Quote from DragonCommando :
semi slicks are the way to go, at least if you are confined to 275 wide tires anyway.

It's definately not your suspension, 275 tires are a bit narrow for 600whp. for that kind of power 325/30ZR20s are probably the minimum you should have if you expect to be able to put that power down at reasoable timing comming out of a turn. That size would just about match your current fronts too.

Unless you plan on changing the rear so you can fit wider tires, you are going to always be limmited on street tires so semi-slicks are the way to go.

275 tyres are not narrow by any means, you can get slicks, semi-slicks, premium road tyres, cheap rubbish and any other shape and size of tyre in this size. You might want to go a bit wider but it's certainly not the end of the world. The run of the mill semi-slicks do not come in particularly wide sizes but there are plenty as narrow as you like. 20" wheels are not necessary, will increase unsprung mass, likely adversely effect the handling and limit tyre choice.

If you're after performance and haven't got budget issues there's no reason not to go for semi-slick tyres, their performance in the wet is a lot better than people will have you believe whilst they're not ideal there are a lot of club racers who race on them in all conditions so they make a perfectly good road tyre for anything other than winter conditions. The semi-slicks that I have experience with are Yokohama A048Rs and Toyo R888 Proxies (GG - hard compound), the Yokohamas are stiffer and stickier than the Toyos but won't last as long, the Toyos make a better road tyre and perform much better in snow and ice should you happen to be caught in it than the A048Rs. These tyres are not cheap though, part worn slicks are usually available from somewhere for the cost of budget road tyres, they're probably a good option but you'll obviously need a second set for wet weather/road use.

Tyres will have different behaviour under lateral and longitudinal loads mismatching compounds/types isn't unheard of in racing and if you can find something that works go for it, obviously if you're really going on a blind guess you'll have to be careful at first finding out the finer details of your new setup. The chances are a good matching set will be better than mismatching less good tyres though.

MSA speed events require MSA approved helmets and overalls, they must also be in date. Unfortunately this is a considerable expense. If you're not running a close to standard car you'll require a rollcage and all the other safety bits.

Track days usually accept anything that looks vaguely full face, out of date racing helmets are ideal (but only use them if they fit and you know they've never been in an accident) or you can get away with some motorcycle helmets (cheap but not great).

If you can't fit you're head in your car with a helmet on I'd look at moving the seating position, presumably you're head is at a high risk of hitting the car especially if you haven't got harnesses.

There's no point getting paranoid about it, the photos of Oxford are at least 6 months old. There are perfectly good uses for this kind of thing, for example I've just looked at my house for next year to try and size up the drive a bit better (rather worringly small given the number of sheds we're planning to dump on it) but thankfully I've also been able to check that there is on road parking, a lot easier than going there.

Quote from S14 DRIFT :
And well, alot of employers would rather train an employee to do things their way, and most people who don't understand are very keen to learn.

Oh dear, back to the point if people are going to make their own decisions whilst working in say automotive engineering they will need at the very least to be confident working out areas and lengths ideally mentally. You can probably make a reasonable mental estimate already of the circumference of a circle or work out the internal dimension of a piece of box section of known thickness and internal dimension. If you can't do that quickly without fuss or consulting someone cleverer (or a calculator) then you don't have much chance of working efficiently. Chances are you already can because of that pointless school you sat through.

Someone also has to be able to understand and estimate stress calculations, otherwise how do you know what size materials to use, just guess? If you're able to do it yourself you'd have a huge advantage, most employers can probably teach you that stress = F/A but they do not have time to teach you the maths to deal with it.

Quote :
Ohnoes 1 year, picky much? That was an attack. The attack took place in 1945... They were being developed, tested and build looong before then. My point is valid.

History would have taught you that the first and only test prior to Hiroshima and Nagasaki happened in July 1945 so you're still wrong

Quote from S14 DRIFT :I'm not sure if y'all get my point. I know that Engineering, mechanical skills and the like require some basic formulae, being taught how to do them 6 different ways is not good use of time. What's more, everyone has access to a calculator so if they need to do 3473985494 tons / 343^3/2 (xy4) then they can simply use one of those.

You really don't get it do you? Understanding and using maths is more than simply typing things into a calculator, if you hadn't been taught basic maths you would be unable to even use a calculator, if you want to get a computer package to do useful engineering calculations you need an understanding of trigonometry, calculus and the other basic mathematical principles you're going to use. People who don't understand what they're doing make rubbish unmotivated employees. If someone doesn't have to hold your hand and be paid for supervising you and giving step by step instructions on how to walk then you're going to be far more productive and satisfied with your job.

Hiroshima& Nagasaki happened in 1945. There was nuclear bombs back then.

My point exactly evidently maths is a bit beyond you (2009-1945 = 64).
