Thread: TOP SPEED for Disco TD5

Of course Landcruisers and Patrols can do over 180kph...

You just have to find a high enough cliff....

I've been putting my mind to unusual stress in this regard .. :roll:

The gearing doesn't change, nor does the govenor ... at 4500 RPM

Ergo ... say 100kph at about 3000 rpm ......... that gives a max possible speed of about 150 kph at 4500 rpm .........


Q.E.D.

Sorry Guys this will be offensive BUT
My old stage 1 Series 3 Land Rover with an unrestricted 3.5 litre V8 will still pull 150-160 Kmh

In the Territory so Its quite legal, I use to work for a company that regularly travelled from one site to another in a Camry in excess of 200 Kmh
(about 1200 km one way) despite all the brain washing in the Eastern States and the revenue raising publicity there are times that high speeds can be travelled safely with out incident.

Merry Christmas

I used to have Elders as customers for company cars, their drivers in SA&NT used to complain about the Falcons being speed limited to 190kph.

I would agree with Hi line on this one. A defender is capable of those speeds but Ive only seen it with chev converted and plently of HP and suspension work.

We have the police doing a speed trap last year at one of our races and the top speed was 197kph and thats offroad!

I only managed 139kph but still had plenty left. Ive hit 170kph in other races.

see http://www.offroadoz.net.au/Events/WA_Even.../speed_trap.php

for real world speeds in 4wds and other off road machines.Car 832 is a GQ patrol and it was clocked at 178kph

Gearing doesn't make any diference.
gravitational acelleration is 9.8m/s/s

so the heavier it is, the harder it falls

Merry Christmas!

So,, is it safe to say that a standard Average Disco should get 150-160 kmh ? on a level average day. :?:

Has anyone had a chipped Td5 disco at its top speed and if so what kind of speed are we talking.

I understand that the peak improvement from the chip in top gear is at about 80-90kmh (torque), but there should be an increase in top speed from the increased hp, I hope. 8)

There is heaps of gearing left before the govenor limits the disco at about 4850rpm, I guess you could with ,,,endless HP,,, do about180-190 before the govenor acts........ :? Again, I do not say this is achievable with the 145KW the chip gives you,, but I am intereseted to hear what people have done in a chipped disco. :?:

Guys,
Unless you live in the territory, top speed is irrelevant. Chipping is about torque. I went from 300Nm to 450Nm and can climb the range in 5th gear at the legal limit. Thats impressive!
It also tows the 1500 kg caravan effortlessly. Thats useful!

Top speed? who cares. Beyond 110 klm/hr you are looking at losing your licence, in QLD anyways.
Even if you drag race, torque is the figure you want to increase.
