Forged rods and pistons aren't going to help that much unless the pistons are also there to lower CR.
How much power/pressure do YOU think the powdered metal rods will stand up to? Remember, the 3L rods are same as 2.5L rods.....
Mercury Maurader Supercharger project 4.6L (described in C&D) powder metal rods failed at about 350 HP. Strongest 2.5L S/C cars are at 350 HP now. Now this is a 3L with turbo. 450 HP maybe.. (actually the 2.5L project turbo of Ken Dutweiller made that-- with forged internals). 500 HP?? You do not think it a bit crazy to invest all the time and money in a 3L turbo that will make at least 400-500 HP when tuning complete and not beef the internals??
So, did he do this??
