I love the talk of this crazyness!!! If there's a diesel equivelant of petrol head i'm that.
Staying tuned..
P.S. maybe do it to a strong engine like a 4bd1 eh? :o;);):D

uummm i didnt actualy say that. the top end would be the same or better depending on how you set it up. Its the bottom end that becomes the problem. as for cost i would sajest that a super charger would work out cheeper over all than say fitting a turbo IF you are able to do it your self. paying for it to be fitted would be a difrent story.
super charger say $350, drive Bsection belt and blocks $100 tops plus ducting say $100 a micro switch and electric dump valve $60. but as tombie pointed out, fitting it all in would be the problem.
done a lot of thinking and messuring and i think i know how i would do it.
move the fule filter ( good time to change to a disposable one.
frount mounting points from the PS timing cover, inlet manifold, back from the inlet manifold.
drive from the water pump, 180 mm Dia B section Blower 140mm Dia
etc etc
salivating at the thaught..... mmmmmm...... supercharger.
It would sound very very good 1 would imagine and would put out some serious torque.
Maybe have to jimmy up a 15 speed crash box to hang on to the bastard though :eek::eek:
Curnow,
Some years ago I completed a number of technical investigations into replacing the Garrett turbo on a Isuzu 4BD1T with a Sprintex (twin screw) supercharger.
In short, the positive displacement supercharger produces a much better charge air flow than a turbo (or a belt driven compressor), in that it is consistant through the rev range. There is no delay in boost pressure because the super is mechanically driven by the engine at a fixed drive ratio (usually).
In my experience of driving a supercharged Toymotor (6cyl diesel) the vehicle drove much as you would expect a petrol powered vehicle with similar output, so long as you do not go nuts, there is no ill effect attributed to installing the supercharger, it is an air pump.
To charge air boost; the TD5 has a factory boost of 15psi (1 bar) so long as you do not exceed this by way of supercharger sweep volume and drive ration, then you will not overstress the engine.
The down side is installation. the MAF and vacume tubes all must be inpalce on the lowpressure side of charge air intake and although the charge air will be much cooler (relatively) than turbo charged air, you should still use the aftercooler to reduce the charge air as much as possible.
Now contrarily, I have recently rebuilt my TD5, nasty case of dust ingestion, and amongst other things, I have ceramic coated the Exhaust (manifold, turbo and exhaust pipe), and Inlet (turbo compressor, inlet manifold). These changes appear to have greatly improved acceleration and response, while dramatically reducing underbonnet heat.
For the cost, you may like to investigate this option first rather than what I suggest will be a lengthy and expensive series of modifications to instal a supercharger (much as I also looked into this alternate myself ).
Sprintex quoted me A$2,500 for an appropriate model for the TD5 and offered to instal, though noe estimate was provided as they had not previously done a TD5.
lastly, before changing any of the factory hardware, cooling the charge air is the most effective improvement you can make. have a look at Laminova water to air coolers, there are a number of peole on the net offering off-the-shelf aftercoolers which can easily be installed in the LR engine bay.
Good luck.

Honestly you blokes rabbit on.....it is easy just get this .Ford Turbo Air Intake Performance Supercharger Fan Kit | eBay

didnt Allard supercharge LR diesel back in the 60's??????
