400+ HP x 2300 lbs x 11 sec Feasability

With an automatic transmission the lost is said to be 16-20%. It may be 18-20% but to be safe I would do 20%. With that in mind I would say about 440 horsepower on the engine would put 352 at the rear wheels. With that amount I would agree with about 11.90s in your sight with the proper gearing and tires.
