Thread: 4.6 with 14cux EFI into 85 110

Couple more....

Either I've been driving the TD5 too long or the 4.6 is using a lot of fuel.

Currently getting 17.5L per 100km

Was hoping for a little better than that. Something like 14l per 100km would be fine, giving me a range of around 500km on 70L of fuel.

My only thought is maybe fuel pressure is too high (still unsure on accuracy of gauge) and it's running a little rich but hard to tell without the right equipment. It doesn't smell rich and it gets up and boogies just fine. I guess I could lower the fuel pressure and test.

Any thoughts?

Hi

I have a county with similar gear with a 4.2 out of a lse rangie but with solex 175 cd,s

My fuel consumption is similar, probably higher.

They are a thirsty v8. I run mine as duel fuel mainly for the range.

Well I've checked the fuel pressure against a known gauge and although my gauge is a little off I don't think the slightly high pressure (now adjusted) is the reason behind my 17.5L/100.

Welcome back to the rover V8 Mick!!

That Mick is the price you pay for the sweet sound

True indeed Chris. I think the reason for the 17.5L/100 is due to the sound of the engine.

Was thinking of selling the TD5 but even Jenn is telling me to keep it.

keep the tD5 and sell the noise...

You're doing well. My cosseted 3.9 (14CUX) is more like 18 to 20 litres per 100km, and that's driven nicely and NO off-road foolishness...
- And its still a gutless wonder. - There's a certain Gentleman over here with a tD5 in a Classic LSE, and it runs rings around mine on nearly half the thirst.
