Hi guys
I would like some advice I currently own a 2010 supercharged range rover sport I am looking at upgrading the power to around 600 bhp with 750nm there are a number of tuning companies that say this can be achieved easily but one company has advised me that with these upgrades I would have to look at larger injectors and fuel pump the mods are upper pulley, e.c.u,engine tune,gearbox tune,and panel filters I know the panel filters can cause issues but.would like some advice thanks in advance

Even if it's feasible, have you thought about the extra stress on components and the insurance implications?

Hi I have always had modified cars and always paid whatever the insurance premium is, this is the price you have to pay for vehicles like this. The range rover svr is already running 550bhp with basically has the same engine thats in mine but with a ecu upgrade, I think that I have read a article outlining that these engines have achieved around 650-700bhp without internal modifications, the issue could be cooling

Even if the engine can take it, what about driveline components, brakes, etc.? If they're all to SVR spec. in your car as well, what do you get for SVR money?

Technically I don't know if the drivetrain is identical but wouldn't have thought it would be that different. To my understanding the svr is simply a modern version of the supercharged sport with 550bhp different body different interior but mechanically the same

I am no technical expert, but if you are comparing a 2010 Supercharged to an SVR, I think you may find they are completely different cars and I don't think they actually share a single component.

As I said technically I don't know my question that I asked originally was do I have to upgrade the fuel system there are 650bhp conversions advertised for my car I have seen the conversions done on various sites and magazines that do not stipulate that fuel system upgrades are necessary

750Nm?

The 6HP28 has a torque input limit of 600Nm...

This is a good point I'm seeing a gearbox specialist tomorrow for a megaflush and supercharger oil change so I can speak to him about it

There seems to be a lot of contradictory information about maximum torque ranging from 600 as you say to 750 but thanks for the advice I will look into it

The transfer box worries me.

I see they are doing a limited edition jag xjr with 575 Bhp

The 6HP32 will take 750Nm as it's an uprated unit designed for the purpose. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Thanks guys I can discuss this tomorrow when i get the servicing done

The 5.0 has the 32?

My knowledge extends to that of the diesel variants

I had My 5.0L S/C Remapped by Alive Tuning, I also had them upgrade the S/C Pulley at the same time. After they completed it, they did test run's on their Dyno. It was producing 750Nm of torque (749.9 to be exact) and they estimated it at somewhere between 560 to 580 Bhp there was some reason why they could not get an exact figure, I think it was something to do with the management system can't really remember, but I do have the Dyno computer readout of the figures somewhere. Comment for the lad who did the upgrade if I remember correctly was something like "That thing is a Animal.

There were no injectors, fuel pump or anything else changed, my insurance company L/V did not even increase my premium.

Cheers
