Disco 1 3.9 V8

[WOZ24]

can any person out in AULRO tell me how many horse power a Disco 1 3.9 V8 has this could help me greatly.
thanks in advance
Cheers Woz:D

Sorry don't know but some of our Discos on here have the Equine flu and have less horse power than others.:D:D:D:D


sorry couldn't help myself

Good lord!
No small wonder my 97 SE7 V8 is a slug pulling our caravan. The AUIII Falcon 6, does it so much better, however the stability of the LRD far surpasses the Ford. Weight is an important issue with a tow motor.

Pity rover did not have a 'gutsy' motor :(

You are confusing horsepower with torque - oversimplyfying it, horse power gives top speed but torque gives pulling power. The disco v8, like many 4wd engines has sacrificed power for low down torque - diesels have good pulling power (torque) but relatively low horse power (top speed).

If you have a problem pulling your caravan you need to look at improving the torque characteristics for towing rather than power - though again oversimplyfying things, the two are linked.

IIRC...

186 BHP
260 lb ft of torque.

Hi Gazz,

I am aware of that :D

2002 Falcon 143Kw @ 4500rpm
362Nm @ 2750rpm

1997 3.9V8i 132Kw @ 4700rpm
320Nm @ 2600rpm

The 4 litre Falcon wins and also is a lot lighter.

However an engine change could be a good idea.

4.6ltr V8 Rover.
166Kw @ 4750rpm
407Nm @ 2600rpm.

Now that IS a gutsy motor :D

Hi Ron - my brother has a Mark 10 and a 420G for parts (only difference being the chrome stripe on the 420). Now they are engines with grunt - they haul such a big heavy car nicely.

Cheers

PS. The DII has more grunt that the D1 owing to quite a few subtle and some not so subtle engine and engine management (and flow) changes.

According to Redbook
All base model 4 door manual V8s

1993 3.5
115kw @ 4750rpm
??nm
1928kg kerb weight

1993 3.9
134kw @ 4750rpm
??nm
1905kg

1994 D1 update
134kw @ 4750rpm
304nm @ 2600rpm
1905 kg

1998 D1
134kw @ 4750rpm
304 @ 2600rpm
1899kg

1999 DII
132kw @ 4750rpm
320nm @ 2600rpm
2010kg

2004 DIIa
136kw @ 4750rpm
340nm @ 2600rpm
2095kg

So the difference between a 1994 D1a and a 2004 DIIa is 2kw, 36nm and 190kg. Does the power more than make up for the weight or is it just how the power is delivered that makes the difference?

The DIIa has a very slightly better torque to weight ratio. Virtually the same.

Mate,

You are not wrong :D
My 420G has an XJ6 SIII head with larger valves and boy, does she fly :)

Towing my off road caravan is definitely much easier behind my V8 D1 than behind the ED Falcon even though the falcon has more power and torque with less weight (145kw 348nm and 1500kg versus 134kw 304nm and 1900kg). The other thing I found was the jump in fuel consumption was far worse in the falcon compared to the Disco.

Really!
We had a EBII before the AUIII and it did use the odd drop.

The AUIII (2002) does 15 - 16 ltr per 100km, pulling our van at 100kph.
The Disco 20 to 25 :eek:

On the highway, the AUIII does 8 ltr per 100km @ 108 to 118kph (nearly 700km to a tank). The Disco.. 16...


Needless to say, we kept the Falcon for "touring without van".

When towing the van I was getting pretty similar mileage with either vehicle, maybe just slightly better with the falcon, due to the fact that the falcon doubled it's fuel consumption but the D1 only uses around 25% more. And as I said, the towing experience was much more controlled behind the D1 than the Falcon. When towing, both vehicles were running LPG. The falcon was a 4 speed auto and there was nothing you could do to stop it from kicking down to 3rd at the slightest incline, whereas the Disco is a manual so I can control what gear it stays in. This coupled with the fact that peak torque (I think) in the Disco is lower in the rev range, is probably what makes the difference.
