The gearbox is the most fragile part of a 172. It is barely strong enough for the standard engine. It is what makes it questionable to turbo a 197. And even a lot of people with standard cars have trouble with the gearbox.

Anything will fit if you have a big enough hammer, or a big enough cheque book. If you are asking whether its a practicable conversion, the answer is most definitely not. First of all it won't bolt up to the block you have. And secondly its too long.

The power loss depends on a lot of things. The revs, the throttle opening, the gear you're in, the size of the tyres, the tyre pressures. If you're talking about the power loss at maximum power 20% is too high a number for a 182 Cup. The experts, the people in the car manufacturers and dyno...

The car manufacturer can approve towing or not for each model. Renault chose to allow towing on all the Clios, except the Sports models. And it made a towbar that fits them, all including the Sport. So you can buy a towbar, and you can get it fitted, but you can't legally tow with it. You could...

http://www.autocarmagazine.com/News/NewsArticle/AllCars/232017/ Superchargers look set to become the next mechanical car component to go electric after a British company unveiled plans for a blower powered by an electric motor. Instead of being driven off the engine by a belt, like a...

The glowing embers indicate its not most of the things suggested.

123.8 bhp at the wheels does NOT correspond to 162 bhp at the flywheel. That's way to high an amount of power (23.6%) to be lost in the drivetrain in a transverse front wheel drive car. The right number is about 15%, or even lower. What that says is that there's serious questions about that...

No, its not, 169.65 bhp.

It surely would. Good place to put it. That takes it out of the engine compartment, taking weight off the front wheels and leaving space for a intake that goes straight into the throttle body. And it puts the weight of the battery down low in the centre of the car to lower the centre of...

They aren't any different.

Airflow isn't directly proportional to TPS. Its not going to flow much more air at 100%. If 78% at full throttle is nornal, fair enough, but I'm surprised they only open it to 78%. Are you sure it not 78 degrees?

Renault's engineering department had come up with a better 4-2-1 exhaust system and a freeer-flowing cat, but it wasn't 10 ps. So the rest came from the marketing department. Renault had released the 172. Peugeot had trumped that with their 180. So Renault's marketing department had to come up...

You attach number places with velcro? Gees, here we have to use one-way screws. Screws you can tighten, but can't unscrew. If you don't the buggers steal your numberplates so they can put them on their car, go buy petrol and drive out without paying, and not be able to be traced from the CCTV...

The lighter the car the less tyre it requires to get the same grip in the dry. In the wet its even more the case. The tyre has to push the water out from underneath it. Newtons laws say the water pushes back. That lifts the car up and causes it to aquaplane. To float on the water rather than...

Yes. If you want a car to understeer more you increase the front roll stiffness, and if you want it to oversteer more you increase the rear roll stiffness. Generally speaking. That general rule assumes that the suspension geometry is good enough that all the tyres are on the ground and...

Your chances aren't good. Its both wider and substantially bigger in rolling diameter.

The faster you wear them in, the faster you wear them out. If you want the engine to reach its prime sooner, cane it from day one. But it'll pass its prime and go downhill sooner too.

The 197 is a better car than the 172/182 in every regard. Except one. And unfortunately its one that's the most important thing to people who want performance. Its a lot heavier. And the same engine has to drag that weight around. If it had only been a little bit heavier it would have been a...

No, LegoHead's got it right. Overboring never loses you power. The maximum amount of power an engine can generate depends on the amount of air it can pump, that's not being reduced, its just that if its the induction system that limits increasing the bore (or stroke) won't increase it much...

Loses the radio anti-theft code. But, seriously ... Engines aren't all the same. Fuel octane/quality isn't all the same. Drivers style of driving (hard, easy) and usage (city, country) isn't all the same. Over time the ECU "learns" these things, but it doesn't alter the fuel/air map that's...

A small correction. The pressure rises as the butterfly opens. What you probably meant was the manifold vacuum drops as the butterfly is opened.

Overclocking is something that if you have to ask other people how to do it, you don't know enough to be doing it. You have to know which CPUs can be overclocked. This is generally ones intended for use in laptops and ones that are produced late in a technology generation. Laptop (low power)...

Can I? No I can't. But I'd like to know how to. Can you?

I think you're all being unfair to the dealer. Yes, the damage around the washer is without doubt due to the mechanic. But its not really plausible he caused all those scratches to the headlight cover. If he did it with a tool he would have noticed the first time. The dealer's explanation...

In the computer field there are "bugs" and there are "features". A bug is where something is wrong and it causes a problem. A uses notices it, you fix it. A feature is where the situation the problem occurs in is so obscure that who the hell cares. A user notices it you say "sorry, that's a...

There's another thread here titled "pet hates". The person who started it points out he doesn't mean domestic animals he doesn't like, he means those little things that annoy you. The term for that is "bete noir", which in French literally means "black beast". It occurs to me that that would...

Did you mean "eddies in the space time continuum"? So someone can say "is he?"

Don't you have laws in your country about screens in cars, and about driver distractions? I have my sat nav running on a Windows CE PDA. But that's all I can do here. I have all my MP3s loaded in it too, but if I do anything but sat nav on a screen that's mounted in the driver's view while the...

Are you ABSOLUTELY CERTAIN the initial advancing of the inlet cam is dependent on the water or oil temperature?

(Sorry Dan, this doesn't answer your question.) Had a Honda. You knew you'd lost the cam belt if the engine turned over on the starter without showing any indication of firing and the "no oil pressure" light was on, because the oil pump was driven from the overhead cam. Is there some similar...
