Hi Guys,

Some of you might remember I've 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-super...029#post153029
