Land Rover 300Tdi installation

JimAttrill · 07-31-2008

Done on the cheap, couldn't afford the DO pump or valve, though there is a DO sprayer and boost sensing switch there. The pump is a Valeo headlight washer pump and there is a VDO non-return valve. I started with water on at .9 bar, then down to .5 bar and now .3 bar.

I can't say that there is more power, though there might be. It feels better, but that could be wishful thinking. One thing I do notice is that the smoke from the exhaust (which it is easy to see in the LH door mirrror) stops altogether when the water comes on.

And I just discovered a 220l drum of Methanol in the back of the garage, bought to make biodiesel.

Well with that pump your not going to be putting out a lot of pressure, Adding methanol will help out for sure.

Thought about boost referencing the tank? Should give you some more pressure and better atomization.å

By boost referencing you mean ignoring the boost switch and pressurising the tank?
There are two things against that. One is that I have the boost switch which cost some money, and also the tank is still used for the windscreen washer pumps. I don't think there are any non-return valves there, so the water would be pushed through the pumps and out of the squirters.

The headlamp washer pump pushes out a lot more pressure than a little windscreen washer pump, with quite a high flow rate as well.

I've been reading your posts and am most impressed with your installation. Do you have any results yet? I have a '91 110 CSW with a retro-fitted 300 Tdi, and am seriously considering WI, again, primarily for economy, but a bit of extra power would be welcome, as I've already fitted an overdrive, but am now a bit over-gear4ed when fully loaded, which is quite often.
