The FIA has approved Ferrari’s request to tweak its engines ahead of this weekend’s Spanish Grand Prix, following a spate of engine problems for the works team and the Sauber team so far in the 2010 season.
It is understood that the reliability problem stemmed from the engines’ pneumatic valve system and air consumption. This solution now qualifies the team from an exemption from the engine development ‘freeze’ currently written into the rules.
Ferrari confirmed that it had "requested and received authorisation from the FIA to make some changes within the framework of the current engine regulations and these modifications will be fitted to the engines to be used in Spain."
Dare I say it, but how many additional BHP will be discovered with this work being carried out?
