I never look forward to getting up at 05:30 in the morning but every time I'm due to visit MSL, it doesn't bother me at all. I view it more as a great day out than a trip to the garage!
Since discovering the IC pump was officially not up to the job (I had my suspicions since the upgrades last year), and the MOT throwing up some other issues (like subframe bushes etc.), a great day out up at Brum beckoned...
Most of the day was spent removing the old parts from the rear which looked like a real pig to do.
Whilst we got good power after the mods back in July 2014, the car stank and I assumed this was due to the decat! However, after confirming a duff IC pump, in hindsight I suspect the original pump had not been up to the job for more than one serious WOT run.
Indeed I smelt another E55K with all CATs but a poor-performing IC pump and that too smelt like mine - so this ruled out the CATs being the cause.
Got the car back on the dyno with the replacement pump, it was back up to a little over the figures we got back then (was 491WHP, now 496WHP and 505WNM). It also feels a lot more powerful than previously more of the time, presumably because the pump now keeps up with demand, and it no longer stinks! Hooray. I assume it over-fuelled to compensate for higher IATs.
I'm chuffed with it and the handling is much tighter now having replaced half the suspension.
So thanks to Acid, Sarim and the gang for another great day out - they all always manage to make you feel like a special guest despite being just another punter really - even when I first went up.
Final mod tally (for now):
Kleemann LTHs, decat, X pipe, standard silencers, Eurocharged pulley, Eurocharged remap, K&N air filters (inherited).
I will post up a video in due course!
Here is the final run:
