Performance Improvement Suggestions

--- Quote from: "Budgie" ---Once you've checked, washed (inside & out) & cleaned everything and it's all as it should be, but you still want some more power then have a look at this site for the Dodge Ram. They use the same injector pump as Land Rover and it's a good guide to get you started.
MAKE SURE YOU READ ALL THE WARNINGS AND ALWAYS NOTE WHAT YOU HAVE DONE SO YOU CAN PUT IT BACK TO STANDARD IF IT DOESN'T WORK!

Thanks - found that site late last night seems straightforward enough.

We (read "me" with Neil hovering over my sholder and supping a beer :roll:) did the diaphram on Gords Disco in the campsite in Belgium. It took about 5 mins to do. :wink:
I would start with the diaphram, as it's the easiest to do, and you'll be suprised at the difference. Only turn yours to about 90 degrees MAX with the standard intercooler, any more than that and your just waisting fuel. :wink:

Please don't take this as an insult if you fitted it yourself, but was it done properly.... the cam belt on my brothers Disco had been done by a 'Land Rover specialist' just before he bought it... yet it was quite a way out. Probably becasue it had been done by eye, not using all the pins!!

Yep... you really need one that reads at least 1.5bar... TIM ones are the cheapest (I can get these a bit cheaper if needed, and check it's correctly calibrated)...

As mentioned in later posts, I did mean inside and out. I usually use paraffin, brake cleaner or something similar. Just make sure you give it a good shake and that it's dry when you refit it. Easist way to start the engine with the silicone pipe that goes from the intercooler to inlet manifold disconnected... this will blow any residue out.

Easy check to see whether you diaghram in the injector pump has a split in it, or is leaking slightly.

This is quite a common thing that gets overlooked!!

Once you've checked all the 'free stuff' this would be my next port of call.

Why??? Depends how the rest of the pump is set up.... on my 90" this was set to max point, and yet didn't give out clouds of smoke (which would be unburnt fuel)
Also, don't fall into the trap of tweaking the mods and testing it by just reving it at standstill. Your turbo will only boost fully under load... i.e. when your driving it.
My 90" did give a bit of a cloud if your reved it hard whislt stationary (but still passed MOT's) but when driving all you got was a light haze.
The real thing you need to worry about is EGT... but without changing overall max fueling you should be safe :wink:

I'm no Diesel engine guru I just go on what I've been told over there years and through tinkering myself. The info I was given was what I said above and I can't see the reason to go to full fuel if it's not needed! :?
Even with the full width intercooler mine is still only set to about 160 degrees (5 o'clock) as it smokes too much when set to full fuel (180 degrees). Maybe the injector pumps have a different setup for the 200/300 TDi Defender than for the Disco. :-k
I agree the vehicle must be driven to see the effect of any alterations, you wouldn't notice any difference (apart from the smoke) at a standstill! :wink:

Well I got impatient, i've adjusted the diaphragm by 90 degrees, with no noticable smoke and bags more performance.
I'll take the intercooler out at the weekend and give it a good clean, I'll also look at the other tweeks to the pump.

found them for just under £30, can you let me know what you can get and the cost, alternativelty I'll pop over to demon tweeks and get one.
