Hi, I was wondering if anyone could share a list of their mods, and the resultant 0-60 times?
Disco 2 tuned td5 0-60 times?

From the road tests of the time very slow, auto 15.8 & manual 14.2 so could do with a bit of improvement 
I think mine is around 11 or 12, something like that, more than 10 less than 14.
Been told near maximum without a bigger TC.
Most importantly I can overtake and it seems fast enough.
Not saying it is faster, but it feels nippier than a D1 V8 I have driven. But that could be as little as better gearbox control. Plus the D1 was LPG.

Biggest issue with 0-60mph is the driver. It is actually not an easy metric to be able to consistently reproduce. And in an AWD vehicle, one that can be particularly brutal on the vehicle. You'd also need a venue to perform the testings, as any slight incline or hill could impact the results.
Car mags generally go to great lengths to have expensive test equipment and places to perform the testing. And even then there is usually variance between what one mag or tester gets vs another.
I say all of this, because I probably wouldn't believe any claimed figures by general owners and Jo Public. And I'd guess you'll actually find it very difficult to find any figures being claimed.

A D1 could be a 3.5 or a 3.9. Big variance in power. Most are autos too. And there was a switch to the electronically controlled auto and serpentine V8's in this period too, which will all change how they perform.
Parkers says for a Td5 D2 14.8 - 15.2 sec, the slower being the auto.
Parkers also says a 3.9 D1 is 10.5 sec. Which is substantially quicker. A remapped Td5 should "feel" very peppy due to the big mid range torque. And with similar peak power should be close to the stock V8, but if you are only at a 150hp map, then the V8 should still be quicker.
I would guess around 165 170 for mine, more than 150 well under 200, but mid range torque is good.
But unless you are drag racing, it is quick enough to not be a pain, and to have fun. On a twisty road mid range torque and anti roll is much more important than outright power.
Mines around 8 x seconds for a 0-60 , lol

Sorry, I should have stated, I'm thinking mainly of manuals, as A: mine is a manual, and B: I am aware the autobox adds an extra layer of lethargy to the disco. I'm not looking for sportscar quick, but I'm curious how much improvement we can achieve to acceleration. I live in a fairly rural location, I'm about 15 miles from my nearest dual carriage way, so I'm wondering how less terrifying overtakes will become if I drop a chunk of change into the engine bay?
I find with autos that is a bit of a fallacy as in normal driving the lack of gear change time makes a huge difference.
Anyway for overtaking a big wodge of torque is great.
Remap - 160 to 170
Remap, intercooler and bit more boost - 170 to 180
Bit more stuff - 200
Aim for around 170 to 180 and it would be a huge difference.

The gearing on a V8 auto disco 1 ruins the performance potential anyway. Mine will get to 60 MPH pretty quick for an old crapper, but it'll hold on to 2nd well past that! First gear will go to a bit over 35mph,at 30 MPH, a hard push on the throttle will kick it down first! It's a bit stupid! Racing off from lights is sluggish at first, then it revs hard to about 5500. With decent gearing, I reckon the time would shorten considerably.
I really want to change to a 1.4 transfer case to get the gearing down a bit. I spend half the time with it locked in 3rd, and occasionally second, around town.

I agree, shorter gearing would certainly make them more peppy and fun to drive. The balance is against how much high speed cruising you may do.
The V8's are nice engines, but they still do their best work at mid and high rpm. Lots of people think they are torque monsters, but that isn't the case. Sure compared to a 2.0 litre engine of the 1980s the V8 makes a lot of torque. But the V8 is still a naturally aspirated engine. I have the 4.6 in my p38, it makes Peak power at the red line. Meaning to get the best from it you need to use full throttle and hit the red line.
