With the chip... sigh.... It will involve head work etc to work well.

D1 V8 Power Ups
morning all,
a few weeks ago i convinced the father that his second car (one for towing, weekends, fun, a 4WD, and "a V8 would be nice") should be a land rover.
this resulted in the hunt for and capture of a '97 disco V8 manual
madness already means the vehicle now sports a 2" lift, ARB bullbar, Kaymar rear bar, and 32" tyres.
the added weight, and indeed the larger tyres have taken the edge off the vehicle, and we are looking to restore it (through means of additional power, not alterations to gearing).
we're fitting extractors and a 2.5" exhaust system very soon, and were wondering about other modifications we can make that aren't ridiculously expensive and won't make the fuel economy worse.
Bruce Davis offers a chip to give 12kW extra and an extra 100km fuel range.
has anybody fitted a DPL chip? how is is going for you and is it noticable?
how does it affect torque?
is anybody else running a different chip?
will we get more than 12kW if the exhaust is factored into the fitting of the chip? or is it a plug and play type module?
any feedback and advice on this topic would be appreciated
thankyou in advance,
cammo and father.

thanks RR
as i said we're not looking to alter the gearing at this stage..
more interested in extracting some ponies out of the motor. surely there are reserves? 136kW? there's got to be more in there somewhere
I'm afraid the real truth is these little eights are asthmatic fuel pigsOriginally Posted by cowboycammo

To give you an idea my project Rangie is getting 4.11's, fender LT230 and an Eaton M90 supercharger with a 3.9
Even with all the above and running 35" tyres it wont be all that quick or fuel efficient. But will drive nicely

thanks again RR
"quick" isn't really the aim of the game.
as you said.. it needs to drive nicely...and something better than 16mpg would be nice (i think this also may have a bit to do with the way the father drives it)
a supercharger hey? i'm thinking significant cost... what are you anticipating the difference in fuel consumption might be?
will the engine handle it okay?

cryptic one for ya......... drop the "cowboy mo" off ya name & fit the rest!!!!
Ivan Tighe is really good!!!
A bigger bump stick you recon?
Supercharging.... Very frustrating getting them set up correctly. The engine will handle it fine but wont handle detonation, thermal spots etc. My setup can only run low boost as has no inter cooler.
Wont make much more HP but will increase the low and mid range torque considerably.
I don't expect it to be good on fuel but would hope to get between 15l/100 on a light cruse and 30l/100 if driven very hard.
I have a duel fuel set up for it so will have ULP for power/extra range when needed and LPG for long trips to keep the running cost down.
I'm having all sorts or drama finding a way of getting the LPG approved with the supercharger

For what it's worth I would start by either changing the diff ratios or put in the Defender transfer case as suggested. I know you don't want to go down that path but unless you can do engine mods yourself it's also going to be pricey to get done. By changing the diff ratios you will have it driving pretty close to what is was like prior to the mods (although it will still use more fuel). Then I would look at playing with the motor (chip it etc) to increase power slightly and reduce fuel consumption. Unfortunately with these V8's fuel economy is never going to be great. I get 450 to 500 k's out of my tank on my 3.9 Disco 1 (I haven't lifted it etc yet). I have a 2.5 inch exhaust with only a sports muffler towards the front and the rear muffler removed. I haven't touched the headers yet as it's very loud as is. But my fuel economy is still as good if not better than that of petrol Lancruisers and Patrols and you can't beat the sound you'll get out of the Rover V8 with the exhaust. Good luck either way and if you fit the Bruce Davis chip please post how the car runs with it because I would be interested to know any differences, good or bad.
Cheers

SubscriberIMHO most of the gains for a 14CUX come from electronic control of the advance curve so if you want to gain power and economy the best route is to fit a piggyback ECU which takes over the vacuum advance function as well as changing the mixtures. During the dyno tuning they will optimise the FA ratio and replace the vacuum advance with a chip generated one usually with much more light throttle advance.will we get more than 12kW if the exhaust is factored into the fitting of the chip? or is it a plug and play type module?

The chip sold by Davis is probably a Tornado from UK, though I do not know this for sure and the main benefits on these chips is to richen the top end and take out several limitations in the 14CUX. These mainly cater for enlarged capacity. However they do nothing for the advance curve/map.
There is also a company in Brisbane called Syntek who do a plug and play ECU to replace the 14CUX entirely. Their top unit has provision for an electronic curve, so i would look at that if I were you.
My 3.9 now has over 50% more torque from 1500-3000 RPM, and I suggest that this is what you need rathe rthan top end power. Even before I fitted a Thor manifold , I had over 20% increase at lower revs.
I have now also fitted o2 sensors, and the 14CUX has all the circuitry but they are not connected. There is a how to in projects.
I now can get 15Lper 100KMH towing a 600Kg camper at 100-105Kmh.
