NGP Racing (VW Shop) up in Aberdeen had a dyno day yesterday, so my buddy and I took our Minis up for a run.

Temp in the eighties, rainy and muggy. No sport button.

Mine: 08 Cooper S w/ JCW Stage 1 Tuning kit



Comparo with his: 08 Cooper S w/ K&N Intake, Alta single-outlet catback



And here's mine on the rollers:

 

Just need a ECU tune to get that JCW into the 200 WHP range!! Still, very respectable numbers for stock, stg.1 JCW.

 

You don't have a baseline from the same dyno, pre-JCW Stage I install, do you? Comparing it to you friend's S is OK, but having a baseline and using the same dyno consistently puts things in much better perspective...

In any event, thanks for posting, it's always nice to see the run instead of just hear/read about it...

 

Nah - no pre-JCW dyno, I bought the car with it already installed. I consider it a baseline for any future mods.

I'm considering an ECU tune, probably an intercooler, and possibly a downpipe. That's the extent of my possible planned mods for the next year or two. I'd like to keep this thing as close to factory as possible, for the remainder of its warranty period.
