Dave- The car has the Dinan Free Flow Exhaust System, High Flow Intake Manifolds, 3.15 LSD Rear End, and the aforementioned Stage III Suspension (which includes springs, front/rear sway bars, and camber plates). I do not know how many horsepower the car is now putting out, but I too would like to know. The car presently is not chipped, so I would like to have it tuned on a Dyno (Conforti, etc.) in the near future. Ray M. >>I TOO HAVE A 97 850CI........WHAT OTHER DINAN MODIFICATIONS DID YOUR NEWLY BOUGHT CAR HAVE? AND HOW MANY HORSEPOWER IS IT UP TO NOW?
