Ok, I need to know what the dish of my 99 cobra's piston is. I'm forging the engine and want to know what the best CC would be for the new pistons I plan to add. I've read in here that my cobra has 9.9:1 compression, should I go lower on it if I plan to add 15-20ish PSI? Would it be possible to add that much boost and a shot of nitrous? (100-150 shot) The boost and NO2 aren't going to be added for a little while and I'd like to have no power loss until then, I'm also installing my Long Tubes and O/R H-pipe, would that make up for the loss in compression ratio? I'm also keeping the stock 4.6L displacement unless I can only increase the rod length. All opinions welcome!!

 

don't know if this helps you at all but i am going to run about 25 or so PSI on my 03 cobra and i am using 17cc dished CP pistons. not sure what it would do as far as power loss while you are still N/A though.
