Creating this thread as a repository for information on supercharging the B8/B8.5 RS5. We have a few members who already have supercharger kits so feel free to post up your setup and experiences.
We know the JHM kit is in the works but there is at least one other kit which is readily available, the PES kit. Unfortunately, that kit, as it sits, needs hardware and software modifications to work correctly.
I believe this is Ali’s car, he’s a member here now.
He uses the PES kit but it’s been reworked by McChip in Germany. His car is currently there, patiently awaiting the RMR transmission cooler kit which just cleared customs.
There’s at least one other kit supposedly in the works by Addict Motorsports out of Washington State but I’ve not heard much in two years on their progress. I know JHM is going full steam ahead with their development. I think the centrifugal SC will also match the RS5’s power band better. Not overly boosted way down low with a continuous pull to redline. This should stress critical parts less as a result.
