Hi all, can i make my fiorino any faster, because its soooooooooooooo slow. I sometimes use the motorway but the best i have got out of it is 55mph. Its got the standard non turbo 1697cc diesel engine.
Technical 1.7 diesel, what can i do to make it faster.

only 55mph?? are you sure the speedo is accurate? sounds like the car has problems, maybe the airfilter is clogged with dirt??? Make sure the tire pressure is correct also as this will slow the vehicle down if its not. I'm sure Alex and Chas can help you to eliminate further possible causes for this lack of power.

I drove along the A19 doing 55mph, and a red 3 wheeler estate overtook 
Hmmmm
How about..
The only fiat worth doing that to, would be a tipo
None of the others are bigh enough to fit 5 adults and luggage
I managed to get up to 60mph today :woot:, sadly it was going downhill at the time

Hi Christopher,
There is something seriously wrong with your Uno... my handbook quotes a top speed of 155km/h (96mph) for the Uno 1697 Diesel (not turbo). Just as Dunc said, in other words.
My first thought is that the injector pump timing is wrong. Maybe someone changed the cambelt without due care and attention?
I must also say that I have never worked on a FIAT diesel engine. In fact, I've never worked on any diesel engine! Diesel cars are not common here (probably 1:100 compared with petrol cars).
The handbook quotes the fuel system as "Distributor-type BOSCH injection pump with hydraulic governor. Static advance: 3 degrees +/- 1 degree ATDC. Automatic control of ignition advance."
So if I was faced with the car, I think I would start by turning the engine to TDC (hopefully there are marks on the flywheel which you can see through a window on the gearbox, jack up the left-front wheel and turn it, while shining a torch at the window), then remove the cambelt cover, identify which pulley is the injector pump pulley, and look for timing marks on it. Also ensure that the camshaft timing is correct.
Haynes does not cover the diesel models, so the search for timing info could be a tricky one! I'll take a look on Google and post back anything I find.
Good luck!

No mention of flywheel timing marks
Looks like a reasonably complex job to check/adjust the timing belt, requiring a few improvised tools... I'm sure it will be worth it though, it can't be doing much good for anything running like it is at the moment!
