Thread: How to get 400Nm from RRC

Surely 400Nm of smooth v8 petrol would would easier on a gearbox than 300Nm of TD5?

I doubt very much.

30 percent is a lot! The torque convertor or appropriate clutch takes up the roughness of the diesel.

From experience v8s can be a lot more savage on the drive line as they crack open quicker. Floor both offroad and see which one hits 5000 the quickest.

The standard drive line will cope if they dont drive it like a sydney taxi.

Years ago we went from Geelong to Buchan for a weekend in a Vk V8. By a very long margin the worst car and worst engine I've ever driven, hence the comment.

The R380 is built to take 380Nm, the ZF HP24 was factory installed behind the 4.6 with 380Nm.
Neither are going to have a problem with 400Nm that they don't have already.
The pulses are only damped by the TC when it's unlocked.

At the same torque level a V8 has torque pulses half as big as a 4 cyl. You can help matters on an engine with fewer cylinders by using a heavier flywheel.

Iveco / Fiat F1C Twin Turbo 3.0 EEV Diesel = 400nm from 1200 rpm to 3000 RPM,
ZF 6 speed 6S400 + LT230 conversion



(engine alone probably cost more than any other option tho)

therein lies some of the problem, the black 5 litre was the most gutless and inefficient of them all...in one of the worst cars, too. I remember driving a 5 litre auto VK ex pursuit car and manual shifting from 1st to 2nd at hard revs, only to have the vehicle almost swap lanes and twist the shell to the point where I was 100% sure I heard the drivers door creak/ pop

Not a good comparison at all.

And the ZF autos in the RRC cannot handle large torque numbers from large 4 cylinder diesel engines, either

600Nm from a tweaked 4BD1T is a bit unfair though.

Territory diesel ... V6 way obselete, the hardest part would be sorting out the modern injection system. This would be a good motor 'cos it's so old now it's well sorted. It's been used in Citroen/Puegeot/jag/etc... for years. It's the oldest/lowest powered version in the fords out here. You could try and bring the 6spd territory gearbox with it.

You could easily "chip" them using the UK market performance chips. Having said that .... How would you get the damn thing running without moving across the body computers and CAN buses

I can't help thinking a small modern torqey petrol engine would be an easier install as you could just "megasquirt" it There must be a nice all alloy V8 readily available designed for torque down low as opposed to power somewhere ...
