Hi Guys,

Some of you might remember I'd been investigating supercharging my 4.2 and had a Group Buy thread going over on A5OC.com for most of last year.

To cut a long story short I spent many an hour in discussions with different suppliers and eventually having had a ride in the first PES charged RS4 in the UK I put my money down for their kit.

PES supplied me the first S5 G4 7psi kit, MRC were the installers and I also paid out for a custom tune from them.

As it stands the kit produces 531ps / 628nm torque @ crank and running on stock clutch.


I also had an independant hub dyno report for my own piece of mind and anyone else that was sceptical about the results...


I picked the car up on Thursday and have done 500 miles in it since including 6 1/4 runs. It's a superb peice of kit, run like stock when cruising around town but is a real beast when you want her to be, just what the RS5 should have been!

Below are a couple links to some short video's....

1/4 mile runs:
First attempt 12.5secs / 114mph. There is more to come (0.2-0.3 secs) with good track conditions.

MRC dyno run:

Independant hub dyno run:


Future plans...

Uprating oem clutch material and pressure plate (not even sure it's necessary yet as feathering stock clutch off the line is very strong)
Possible lightweight flywheel but can't find one on the market yet
Lightweight wheels
Water/Meth
More later down the line!

For anyone considering such an upgrade on the back of my results PES are also having a G4 kit sale details here .... http://www.a5oc.com/forums/pes-supercharger-kit-t14819.html?p=153029#post153029

Dam MRC do it again, not heard any great things about PES software and they did a crap job of my old 2.8 G2 kit with little support from them.

Yep I had heard this about PES's software in the past and decided to go with MRC's tune because of this. However, since making that decision I have heard there are many S5's running just fine on their software. One in particular I've been in contact with has had his kit on for 34k miles without any problems so I wouldn't want to lay that claim against them as far the S5 goes.
