Manthey Racing's second-placed Porsche 911 GT3 R has been disqualified from last month's Nurburgring 24 Hours.
The #911 Porsche shared by Laurens Vanthoor, Earl Bamber, Michael Christensen and Kevin Estre, was found to have irregularities in its engine performance during routine post-race scrutineering checks.
A dyno test showed the car exceeded the 494bhp (including a four percent tolerance) allowed in the Balance of Performance for the German endurance classic. A re-examination using a different method did not produce the values prescribed by the BoP.
The decision to disqualify the #911 crew was communicated almost two weeks on from the conclusion of the race, which Porsche had controlled until Vanthoor incurred a five minute 32 second penalty for failing to respect a slow zone.
Vanthoor's infraction handed victory to the #4 Phoenix Audi R8 LMS of Pierre Kaffer, Frank Stippler, Frederic Vervisch and Dries Vanthoor.
Moving up to second following Manthey's exclusion is the #3 Black Falcon Mercedes-AMG GT3 shared by Maxi Buhk, Hubert Haupt, Thomas Jager and Luca Stolz, while the #14 Car Collection Motorsport Audi of Rene Rast, Marcel Fassler, Christopher Haase and Markus Winkelhock inherits third.
Manthey has the right to appeal, and has up to 96 hours (four days) from the communication of the decision to do so.
