cegerer 2.5T
Look in Bruce Andersons P-car handbook at the table of engine designations. P raced the 2.5 with a66 or 70.4mm crank. With the 66 they used 89mm bore pistons to keep under 2.5--yours is just over 2.5 with the rS pistons. They used 906 cams, 41mm ports, 10.3:1 comp and weber 46 IDA carbs --The factory claimed 275 hp at 8000rpm. Thats what I wnat! not 250. I would suspect that your 2.5 is very driveable and not peaky at all like the racing engine. I was wondering how you liked the combo. Bruce A. said in his book that the resulting comp was to low to give good results. That idea evidently is open to opinion. Youve got one how do you like it? Do you know if they did anything to up the comp ratio a little bit?
