Adelaide Q: TD5 power vs TDi 300 power

I think they may of rounded it off the last one was further on in the sales list 8O

Thats my theory anyway :roll:

Baz.

As mentioned above aerodynamics play a part in it all. Now matter how good the engine is its still shaped like a house brick. Matt

so defenders are the ordinary house hold brick and discoveries are besser bricks?

Dont think for a second i am bagging defenders i love them, but the shape does hinder ther forward momentum somewhat. That cant be denied. How much worse it is than the disco i couldnt tell. Has anyone got a wind tunnel we can borrow. https://www.aulro.com/afvb/

Nah!

Defenders a aerated brick https://www.aulro.com/afvb/

And yeah, I love mine too...

Just reviving this old post with a quick follow up. I've taken off the canopy from the back of my 130, and now I can go up all the way up the freeway in 5th gear, so looks like it is predominantly a weight issue more than aerodynamics.

It is an all aluminium canopy, and before I took it off I estimated it to weight 200-250Kg. Wrong! It nearly tipped my tractor over lifting it off (I didn't bother put on the counterweight), and when I rang the fabricating company who made it I found it was 600Kg. I was miles out.

So, drop 600Kg off your car and the performance increases a huge amount. No wonder auto makers all want to make parts lighter.

but the manufacturers keep making the whole car heavier with each successive model ;)

And FWIW, the high range is different 'tween a 'fender and Disco, with the Defender using a 1.410:1 high range, and, IIRC a Disco around 1.22:1, so the overal final drive ratio is slightly lower in a 'fender, but actual gearing possibly works out the same when tyre diamater is taken into account.

I've got a 'new' bog standard 2001 TD5 130 running on standard 7.50R16 tyres and it just won't go up in 5th, which I was expecting.

I've got a 97 TDi300 Discovery and this 'almost' goes all the way in 5th, so I was a bit disappointed to have to shift down to 4th for the whole way up in the 130, seeing that the TD5 has a reputation for more power.

Is there any simple test (maybe a Dyno test) to see if it is putting out a normal amount of power?

I can't be bothered reading through all the replies but apologies if it has already been said....

1 - IIRC, the 130 is heavier than the Disco.
2 - The Defender has the aerodynamics of a brick.
3 - The transfer boxes have different ratios between the Disco & Defender.
4 - Tyre sizes. The 130 runs on larger tyres (which are harder to turn).... This makes a BIG difference.

If you want to try a little test... Stick some smaller tyres on the 130 & give it another go. :huh:

I'm somewhat astounded that it is that heavy, but as well as the weight , the aerodynamics would have been affected as well (just how much depends on the canopy) - and this may have been a larger effect than the weight.

My County will tow my big trailer comfortably at 100km/h (provided it is level)- but only if I take the rear tailgate off the trailer! This tailgate is about a foot high and 2m long.
