Don't. Not worth the effort, time, money, frustration or results.
4.6 rover v8 is easy relatively cheap these days.
I have seen them advertised for $800 quite often
I have a '92 classic with 3.9 that is in generally great shape, but I would like to improve the power under load for towing trailers (approx 1.3T) through rough terrain and sand. Currently towing up hill feels underpowered. Has anyone put a supercharger on either a 3.9 or the bigger 4.4l engines and is the increase in power and torque worth the expense? What are your thoughts?

Agree,....don't do it.
Reason?....the basic engine ain't good enough.
By all means, seek more power, but the way you suggest ain't gonna cut it.
Pickles.
I shudder to think where you'd find a super charger setup these days, I imagine they were always rare or extremely expensive. I've actually worked on a super charged 3.5 RRC and I've also fitted a 4.6 high comp motor to another one. Out of the two the 4.6 wins hands down as it isn't encumbered with this extra lump of machinery in an already crowded engine bay. The 3.5 ran an aftermarket Haltech ECU and timing system, the 4.6 ran (still runs) quite adequately on the stock ECU.
Thanks again gentlemen, your advice is much appreciated and confirms what I thought, alot of expense with questionable return. I will keep working on the options, but then again it might be as simple as reduce the weight in the trailer! Cheers.
Seen this on the weekend.

Now if I can find somewhere to fit a big Lithium Ion battery in the Rangie one of these would be sweet!!

Easy, just put them where the left and right sill tanks would go....
Drool
Put an LS in it!
Someone had to say it...
Almost ANY other engine is an improvement... from 3L MAZDA diesels, to 307 Ford v8 (needs shoe-horning and light R foot....)
My 3.9 gets embarrassed on a flat road if you hitch a solid 4x'6' box trailer onto her...- before loading it...
ford 'Yellow' injectors may improve it a tiny bit... but the problem with the 3.9 is that it's a LOW compression design, and I'm told the inlet manifold leaves a lot to be desired... The engine is a lemon, and always will be a thirsty & gutless failure, IMHO.
Some folk like the sound of an 'unbalanced' 8 cylinder contraption...
The 4.6 is looking the most economical way.
(I'm taking the easy/sensible way out, The Lady Sarah is up for sale.... maybe replaced with a Chinese 4WD... performance & costs couldn't be worse!)
