Are you interested in supercharging your land rover range rover ?
Range Rover Classic 3.5l to 3.9l V8:
Powerdyne performance and vortech superchargers offer a supercharger kit for your engine. The kits provide three options for power increase depending on the boost pressure:
Stage 1 kit: 7 psi & 212 HP
Stage 2 Kit: 9 psi & 228 HP
Stage 3 Kit: 14 psi & 283 HP
Stages two and three come with a water injection kit for increased cooling.
Further power increases can be attained with additional engine performance parts such as genie high flow exhaust headers and a Borla performance cat-back exhaust system.

Borla Catback system for 3.5 – 3.9 liter V8
Range Rover 4.4 liter V8:
Arden performance, a German tuning company specializing in luxury performance vehicles have developed a complete performance package for your Range Rover V8.
The package includes:
1- An engine rebuild kit including:
a. Stroker crank bringing up the displacement to 4.8 litres
b. Lower compression 9:1 pistons
2- Complete supercharger package
3- intercooler
4- ECU reprogramming
The kit produces an astounding 500 hp @ 6250rpms and 516 ft.lbs of torque @ 4250 rpms. This is capable of accelerating the vehicle from 0-60mph in a short time of 6.5 seconds.
Performance can further be improved using Arden designed ‘off road only’ performance headers and high flow cats. Furthermore, a high flow exhaust system is available jointly through Arden / Meisterschaft

Interested in building your own kit?
Here’s an interesting application performed on a 3.5liter engine (similar to the Range Rover 3.5) found in its sister car the TVR.
The kit built here includes:
eaton M62 superchager
Custom pulley plate with extra idler and tensioner pulley
Custom supercharger outlet plate
Custom supercharger mounting bracket
Modified intake manifold (rotated 180* for added clearance for the superchager)
Relocated pre-supercharger throttle body
Recirculation and bypass valve connected pre-throttle body and post supercharger
Custom mounted front mount intercooler
Vortech SFMU (super fuel management unit)
Relocated Air flow meter and air filter pod
A zex nitrous oxide wet kit for additional power delivery
When all is said and done, the completed kit delivers 250 hp without the nitrous oxide injection.

I have a 2006 Range Rover Sport HSE, (30k miles) is it possible to get 500bhp out of it and how much would it cost ?
Thanks

Hi Terry.
I did a bit of digging around … it seems your range rover makes ~305hp @5500 RPMs.
There are probably a few ways you can do this…
1- If you want a packaged solution… talk to hamman… they’d have to convert your car to ’sport’ spec buy installing the factory charger off of the 4.2 LR Sport. Then on top of that add their kit which takes the LR Sport up to 475hp (the kit includes an overboost pulley, full exhaust system, fuel injectors, and a retune)…
2- You can find a place to make a custom kitted package for you … some place like JE engineering
3- If you’re a DIY kind of guy … you can get together all the parts you want (and need) to make that power figure and then team up with a local speed shop that has good fabrication capabilities to make the supercharger brackets and belt pulley system for the car… after that is fabbed up the rest of the install is straight forward and you can do yourself if you’re mechanically inclined…
For this route I’d probably go with a centrifugal like a Rotrex C38-61 supercharger rated, coupled with a supersprint header and complete custom x-piped exhaust system, and then for fuel tuning i’d go with a maf/injector combo where you do something like get 80% larger injectors and transplate your mass air flow sensor into a larger housing (pipe) that has an 80% larger AREA… that will give you a good baseline tune … then you can get the car fine tuned at any speed shop that has the capability to flash the landrover ECU (or by taking the car to a dyno (rolling road) and getting your rpm vs air fuel ratio data for your car, and then sending that info and your ECU to a company that can flash it so that they can write a tune that matches your car’s fuel needs exactly… and that will give you the exact tune).
Cost is up in the air but you can price what i mentioned above and see what it comes out to:
Rotrex C38-61 trim
Custom mounting bracket and pulley system
New belt
2 steps colder spark plugs
Supersprint/Hammann Headers
New intake system to the charger
Air to air intercooler of appropriate size for 500hp.
piping supercharger to intercooler and back to the throttle body
8 upgraded injectors at least 375 cc/min
New bosch MAF or new MAF housing (you can probably get a housing in the right size from the audi / VW crowd as this is a common swap for them and they use the same sensors)
And finally a re-map …
Let us know how it goes…
hey i have a landrover 110 3.5v8 wpuld it require anything extra other than fitting one of your kits?
Most kits work well out of the box.
But I’d add a large bore header and free flowing exhaust to any basic supercharger kit.
Then I’d check my fueling and get a retune.
Out of the box kits work, but having a higher flowing exhaust system gives you a more powerful and more efficient set up that will make more power at lower boost. This in itself reduces your octane and ignition retard requirements. But you do need to get it retuned or at least get it checked to make sure it still has enough fuel in it, since the whole system is flowing more with the upgraded exhaust.
The only other thing most kits ignore is the right heat range spark plugs. Go 1 heat range colder for every 75 to 100 hp over stock… and go with Iridiums or coppers, never platinums.
