Test driving a car for power on an empty tank?

If you could find some way to put your car in a dynamometer you would find out how much power it is producing. If you can do this before and after the chain swap you will know whether the chain was the problem.

Is this really a biased review? He claimed the lack of power is how they all are, but I feel like that one would have run quite nicely with even just a quarter of fuel in the tank, half, or even full. But the needle was on 0!

I'm repairing my car at the moment. I knew I would need to remove the fuel tank so I drove it till the fuel light came on. And then drove it some more.
We came to remove the fuel tank and there was still 10 litres of fuel in it. Don't use that as a reason to keep driving after the light comes on but the tank does have reserves beyond the empty light.

but I guess with the heavy body then there is going to be that pull on the chain.

Do you have the slightest idea what a timing chain does? What relevance does the weight of the car have to the load on the timing chain? The timing chain is working against the valve springs (mostly) and the friction in the camshaft journals (slightly). Neither of those are affected by load on the engine, weight of the car, whatever.

And the "heavy body"? Isn't this one of those tiny Vauxhalls?

Is this a diesel? Perhaps you are used to petrol cars, diesel cars tend to be a different type of power delivery so you need to change your driving style.

But they invited me in yesterday where the service manager test drove my car, going at a speed where he didn't have to lift the clutch up all that fast on gear changes so he didn't witness the jerky motion I do when changing when I have to set off at quite fast speeds and over-rev.

Out of interest, JLawson, why do you have to set off at quite fast speeds and over-rev?

Are you often the driver of a get-away car? :eek:

I suspect the fault is located in the drivers seat.

My car is a petrol and I've never drove a Diesel before. The thing is that I just know the car isn't performing how it should be. It's had a really good week this past week but yesterday I noticed the power drop yet again, where the car just didn't want to move..

When other inspections have proven there is numerous faults with the car? Yeah okay whatever you say

Thankfully I'm not :rotfl:

I meant it by the roads he was driving on around the dealership as residential areas so he was doing about 20mph so he could start off slow, change gear slowly.
Whereas there's a road I often travel on, I go down a narrow hill and then back up it. The limit is 30mph but once at the end of that road, you have to emerge onto a 40mph road, and it's a very busy one so in that respect, I am required to pull out and go pretty fast.

And this is what confuses me, sometimes the car is good at getting out there, other times there's a pull and delay and I was nearly hit by a truck a few weeks ago
