I'm sure the McLaren team will be the first to admit that their start to the 2014 season could have gone better, especially as they have the advantage of the best powerunit on the grid. It's not all about the powerunit though and their rival Mercedes has clearly done a better job of the catering the whole package including the aero side to the 2014 regulations.

For Barcelona the team arrived with new components to try and close the gap to the front but with a deficit of around 1-1.5 seconds to the Mercedes any upgrades they bring would need to find around 2 seconds per lap, a monumental amount of time to find.

Struggling to replicate the level of downforce some of their rivals are achieving McLaren arrived in Barcelona with a new perforated diffuser gurney. You'll note that the perforated Gurney extends much further around the periphery of the diffuser toward the footplate, looking to extract more downforce from it. 
Why not just extend it to the bottom of the diffuser? I hear you say, well it's all to do with the quality of airflow in the region, placing something like a gurney here requires enough airflow otherwise you get separation and therefore lose downforce. You'll note that the team have also made some changes to the rear brake duct fins too which are undoubtedly allowing a better quality of flow into the region around where the diffuser gurney has been extended.



Whilst I'm trying to keep atop of the blog you may have noticed of late that there is less content appearing. For those of you that haven't realised, most of my work has now been moved over to where I'm working with Giorgio Piola.

As some of you may have found out already I'm also working with the Missed Apex crew on their podcast from time-to-time, either doing race reviews or dedicated 'Tech Time' shows.

I've embedded the latest version of the podcast below and will update this a frequently as I appear. However, please head over to Itunes if you want it to appear in your player when episodes are available. The show is great to work on and has a great lineup of 'regulars' but has also enticed some bigger names recently too, with Will Buxton and Bradley Philpot on shows during the summer break.
