HI, I,m currently working on a 1999 4.6 Range Rover with the bosch engine management system. Looking for a company that supplies a supercharger for this vehicle. Found one at "chariots of fire" but they want the vehicle shipped to them for the work. Right now we are doing a computer upgrade from power chip group and a twin tip borla exhaust system. Also a k&n air filter, but would like a cold air induction system if any one knows of one. Thanks for any help that can be provided.

Perhaps you should have purchased a fast vehicle to being with. Go fast mods are not cheap and even with a supercharger, I doubt you'll ever see more than 220HP to the wheels on a dyno. All the while being past by every other SUV out there. This was the saddest fact that I had to swallow after buying my Disco. I used to own a heavily modded S4, too bad it couldn't tow my boat or I would have kept it.

Keep the rubber side down and good luck in your pursuit. :drive:

I don't know why people get jumped on for wanting to get more power out of their Rover. Personally, I doubt anyone here would complain if it moved a bit faster when the gas was applied. Personally, I have better things to spend money on, but if I had the cash, I certainly would look into options to give me a bit more "ooomph". I think my first options would be better exhaust flow, combined with a performance chip, just like Rovermech is doing. Boosting intake would be the next logical step, although I would probably stay away from a supercharger for reliability reasons. I doubt you will hear anyone that drive a 2003+ RR complaining about too much power...

P.S. The first time I drove a RR ('98 4.6 HSE), I could not believe how slow it was, even compared to my 4cyl Volvo wagon. That did not deter me from buying one, and I was happy to find that the '98 must have badly needed some service, as the one I bought ('97 4.6 HSE) is a decent amount faster. Never-the-less, it is still rather slow.

reply to everyone tha posted

Thanks for the posts so far, I actually forgot about overfinch, but to clarify a couple of things. One this is not my rover but a customers I work for an independant garage where I work on rovers, second cost is not an issue for my customer, third the rover is not used off road, I know it is a shame that it wont be but the customer is always right, right? We also found a rear sway bar package for the rover. Ive been working on rovers 7 years and love them personally and know first hand how capable they are off road.


p.s. Thanks for the support coach.

What sort of supercharger is your customer contemplating, because there is basically two ways to go. You can go with an Eaton style that sits between the manifolds or a "hair drier" type like Vortech, Paxton or Pro charger to name a few. From personal experience, the Eaton supercharger gets too hot, and it's difficult to intercool it, and, at best you will only get around 5 PSI boost. Installing a smaller pulley to make it spin faster for more boost only works for a short while before it s**t's itself. The hair drier type can be run at higher boosts, but if the vehicle is a manual, you will experience 'Lag' which does not happen with either the automatic, or with the EATON fitted.
If your customer decides to supercharge; to do it properly he will need to have deep pockets otherwise, he had better carry a bucket with him.
He's a short list of what he needs:- Intercooling, bigger injectors, a fuel pressure regulator, a good aftermarket ignition system, leads, coil, MSD or similar, after market oil cooler, a computer system such as Haltech, or better still, a Motec, preferably a M48 or M48 pro.

Come back to me if you want any more info.

FWIW, once you have fitted a supercharger to any vehicle, Rover or otherwise, you will find it like a drug.

Why is RR so slow?

There is a very good reason RR's are so slow. It's a design feature!

British engineers were very taken by the reports that it takes 4 days to drive across the United States.

So they got in their beloved rovers and started an expedition from Cardiff to London. To their dismay and suprise they found it only took 1/2 a day.

This of course truely insulted British sensativities. I mean how dare those insolent farmers take longer to drive across their 3rd rate potato patch that it takes us Royal monarchs of the world to drive across our magnificent jewel of a country. Clearly the Americans were cheating some how!

And of course the British Engineers immediately saw through the "plot" of those bothersome colonialists. So they did the same thing that the American engineers were doing - they detuned and slowed down the cars, and since they are clearly the better engineers - they trumped the americans by adding in 1 more important design feature -

Lucas Electrics - That assures that a trip across Britain often takes several days!!

Problem solved - bully for you

To the engineer, all matter in the universe can be placed into one of two categories: 1. Things that need to be fixed, and ...2. Things that will need to be fixed after you,ve had a few minutes to play with them.
Engineers like to solve problems. If there are no problems handily available, they will create their own problems. Normal people don't understand this concept; they believe that if it ain,t broke, don't fix it. Engineers believe that if it ain't broke, it doesn't have enough features yet.
