This weekend's upcoming Belgian Grand Prix will be culmination of a very hard three week Summer break for the Honda engineers and the McLaren team they power. Whilst the factory gates have been shut for the teams the past three weeks, Honda have been working throughout the break to bring their updated engine to Spa. The Honda engineers will bring a new engine with an increased power output, which they have publicly stated they hope can match the power output from the current Ferrari power unit. This is bold statement considering the Honda power unit has been the worst on the grid this year, whilst the Ferrari power unit is best of the rest behind the dominant Mercedes power plant. Honda have decided to try and capitalize on their double points finish in Hungry, of which Fernando Alonso gave them their best finish of the year with 5th overall. The team have decided to use some of their remaining seven engine tokens for this weekend, hoping to vastly increase their power figures without harming their fragile reliability. Honda motorsport boss Yasuhisa Arai made reference to his hopes the increased will not compromise their reliability when speaking to F1i.com recently. He stated "We will increase the power output, but at the same time we have to check the reliability because if the power is going to go that high then maybe some areas are a little bit weak. We have to check." Honda are clearly quietly confident about their new, more powerful engine they will bring this weekend. Their timing is crucial also with the upcoming Belgian and Italian Grand Prix, which are held at Spa and Monza, both very much power circuits.Whilst the Honda engineers are rightly cautious about the effects the extra power may have on the overall reliability of their power unit. If Honda's new engine can stay reliable throughout the race weekend, McLaren will be rightly hoping the increased power from their Honda power unit will propel them to another double points finish as they look to build some positive momentum after a very difficult first year of their partnership with Honda. A double points finish would also be a major statement from Honda itself, as the Spa circuit is mostly centered around having a very powerful engine, save for the technical second sector. For Honda, Spa will be a good warm up for them and their new power unit, although the real litmus test will be the all out speedbowl that is the Monza circuit. Will Honda's new power unit prove the step up both McLaren and Honda need if they want to return to their much loved position at the front of the grid?
