Just got a 1.9 TD but due to the work im doing on it i have not been able to take it for a spin yet (dont think it will like moving with those engine mounts undone).
I therefore have two questions really.

Firstly what sort of performance will i get in standard trim. ie MPG, top speed and how many days for 0-60?

Secondly i have never had a diesel car before, is it possible to up the pony's at all or is this just silly talk?

I have seen people quoting figures on here but they were all petrol versions.

Many thanks, Mark
 
Diesel isn't about HP, it's about torque!

Gobs of it!

Acceleration for a 1.9TD is ok, probably better than my 1.6ie.

But it is basically - how quickly can you get it into top, then drive it like an automatic... they should pull from 1200rpm and really take off at around 2000ish.

And the frugality is legendary... 45+mpg at 70mph.
 
I said it is OK, not great.

It is a different delivery - short rev range, more torque. You just get it up to speed and stay at a more constant rate. You are less troubled by hills, wind, etc.

It is possible to play with TD engines to make gobs of HP as well as torque, but you are hampered by the short rev range - that's why there aint a lot of diesel race cars.

If it is nippy handling and quick bursts of Italian acceleration, forget a diesel.

I currently have a 1.9TD and a 1.6ie and for belting round town, I would take the ie every time.

The revvy pick up suits roundabouts, intersections, nipping about town.

For going on holiday, commuting, and carrying a load, I'll take the TD.

You have to remember that this tipo will be up to 10 years old, diesel engines have advanced so much in that time. If your after something good on fuel, that will be reliable then take the tipo 1.9! Id have a diesel over it anyway.

If your not happy with its performance then buy a sprinter van :p
 
If you take a look at some of the Peugeot 306 TD tuning pages on the web, you'll get an idea of what you'll want to get done to improve the performance of the TD. Upping the boost a little and adjusting the fuelling will result in very noticeable gains in performance at the expense of a little economy and some smoke off-boost. If you can live with a puff of black smoke below about 1800rpm and only 40mpg rather than 50, you can chase 105 - 110bhp and probably around 160-175lb/ft torque if done properly. Fitting a large intercooler will help if upping the boost as when the turbo is working harder induction temperatures rise greatly - get yourself a boost gauge, and see what boost its running, its not uncommon for these engines to need some adjustment anyway, and upping the fuelling on below standard boost will result in lots of smoke and a reduced level of performance. A diesel injection specialist will be your best bet to do this otherwise there's a lot of trial and error involved, and going too far with a screw could result in expensive repairs if you aren't sure what you're doing.
 
One of the easiest way's to get more poke out of a diesel is simply advancing the pump timing to make the engine run more efficiently. You won't see the same gains as a later emissioned engine which are hugely retarded to meet the regulations however you will get noticable gains. You will get a heavier diesel knock and a little more black smoke with this method.

As mentioned previously, you can adjust boost fueling easily too (afc) but I would do that after adjusting the pump timing.

Be carefull about raising the boost pressure as this will seriously affect the cylinder pressures.
 
Thanks all.
Car is nearly ready for the road now (well at least its MOT).
Think ill run it for a while to see how it is then might have a tinker with it.
Thanks again
