Title: Range Rover Engine V8
Post by: Ned Kelly on 08 February 2009, 19:07:27
Hi guys,anyone know of the best size engine to go for as I have a choice of 4.0/4.4/4.6. presumably the bigger the cc the thinner the walls,and there lies a potential problem.
Thanks

If I remember correctly they had problems with the 4.6 as it was bored to the engines limit I read on a Range Rover forum when we had them.

There is a porous block problem with one of those varients - not sure which though.....

They are all the same bore (94mm), its the stroke thats different.

Porous, no not really.

The 94mm blocks do have more isues with liners dropping than the 89mm (of 3.5 Fame).

Should have added, age is a key thing here to as the block design chnged around 93ish

Whats the application?

I have to ask, where is the 4.4 engine coming from as these were only ever in production in oz unless its a 3.5 with a stroker kit fitted!

For info

4.0 (its actualy a 3.95 litre engine and the same capacity as the earlier 3.9 units) - 190 Bhp - 320Nm torque

4.6 - 225 Bhp - 380Nm torque.

i have to laugh, i can get both more power and torque out of my 2.4t after remapping and have nearly the same power as standard :P

Yes but, you will get a peeky horrible over blown delivery of power as a result.....the V8 would beat it in the same chassis with ease.

Remember also that the figure is that as delivered from the factory with no mods

it's actually quite a good power delivery, the turbo comes in at 1800 revs so is there from about the revs you setoff on to when you change gear and fades towards 4000 revs
plus its 5 cylinders so really quite smooth!
the volvos 200bhp and 285nm as standard

Makes no odds....wind up a turbo and you compress the torque delivery curve.....

Further to this, below the point where the turbo spins you get little go, this is for two reasons

1) A restricted inlet setup due to the addition of a turbo, intercooler and miles of pipes

2) Lower compression ratio.

A car with the V8 lump would be way ahead and probably slipping int second before your boost had even arrived!

Physics mate.....its a bugger!

lol which is why in places i can have the 2.0t vag cars ;)
anyway after buying my volvo i quite like the idea of getting more of the potential out of the car, makes it more efficient too in theory (in practise though it often has adverse effects)
anyway... would you really want to race a 4.6 range rover against my volvo?

Not really a challenge for Santa Pod is it!  ::)

When it comes to towing a horse box though i'd use the Range Rover everytime  ;D
