    I am posting on behalf of a friend who has a 2015 5.0 supercharged with 80k miles. He recently spent 3k on his service and was advised he needs both timing chain and supercharger coupling replaced. The noise does not happen always. I would like to know if the car does really indeed need new...

    Hi all, I have been playing with the Torque Pro app and have been monitoring boost pressure. I was told that stock pressure for the 5.0 SC is 9.6 psi. I noticed that the electric throttle does it's own thing regardless if you have the pedal to the floor. I was able to see the throttle come open...

    My 2014 Range Rover HSE, bought new from the dealer and now at 64K miles, has a rattling noice coming from the engine. The dealer say it is the bearing from the supercharger. Costing close to $2,000 to fix. Seems a lot to me for a bearing . Anybody having experience with this ? Actually like...

    I’ve been thinking about getting a set of aftermarktet crank and supercharger pulleys. Found a set on eurotoys and looks like it can do quite a bit in terms of responsiveness and HP/Torque, especially with the ECU tune. Has anyone used their stuff and any regrets? Since the crank and...

    Was thinking of changing out the supercharger coupling on my 2013 with roughly 75K miles. Has anyone done this as preventative maintenance? Is it worth the cost or should I wait until I start hearing some noise?

    Hi! does any one know how to Diagnos a supercharger on a 2006 Supercharge with 200,000 km?

    Hi all, Just recently aquired a 2017 RRS auto. Loving it so far. Just have to ask if anyone knows any technical info on the factory supercharger?? All I can seem to find out is that it is manufactured by Eaton I believe one of their TVS 6th gen superchargers. As there are a few different...
