I have a 2003 GT2 that runs great in a straight line. I had the car on the track for the first time and going into fairly high G turns I loose power. The feeling is like it is having fuel starvation. I sure didn't want to be running lean so I parked the car and took it to the shop. They went through the fuel system everything checked out ok. i.e. pick ups, filters, pressure, debris in tank etc.etc. The problem continued..back to the shop..and I was told that one of the turbo hoses was cracked and when going into curves the flex of the engine in the mounts was allowing the crack to open up and therefore loosing boost in one of the turbos. They replaced the hose and I stil have the problem. It is back in the shop and they are still looking. Any ideas or insight would be appreciated.

 

Was this something that you detected "feeling" a loss of power like the motor was missing or that it just lost grip? If it like a loss of momentum becuase of grip I would check our the LSD. otherwise I can't figure what would cause loss of power if its good going straight. the only think I could think of in the turns would be LSD. That can be checked by jacking up the car both wheels off, then block one tire from turning and try to turn the other, should have plenty of resistance. somewhere i saw a value with like 53 ft lbs of resistance but don't rely on that number. Good luck keep us posted.

 

It is not like it is missing. It does not sputter at all. When it happened initally, I thought for sure it was fuel starvation. I have a race car and it acted just like my race car prior to installing a fuel cell. When I am going into a turn pretty hot it will start slowing. I can put my foot to the floor and no response at all until it gets slow enough and then full power immediately.
