[QUOTE="tt335ci03cobra, post: 15575612, member: 68944"] [ATTACH=full]87406[/ATTACH] I think they can pull off a fpc to be honest. People say it's too brittle but I call shenanigans. The damn things have made 1080whp already with turbo systems and 17psi. So do many Ferrari and exotic builds. Cpc and fpc have no dramatic difference to strength when properly balanced. An imbalanced cpc, even fractionally, will last no where near as long as a well balanced fpc. If anything, the fpc is a better design for boost as it scavenges smoother and exhausts completely. Cpc is inherently worse for boost. Part of the reason it's easier to get 2-4hp/L with a turbo Honda 4 cyl vs with a 5-7L v8 is cpc vs fpc, overall stroke throw, and so on. It might be wiser to drop a little stroke and go down to 5.0L to be honest, but regardless, since Ford has already found how to balance an fpc, supercharging that mill makes more sense vs putting a cpc in it. The reason ford is selling a cpc 5.2 Aluminator making 580hp is to satisfy the wants and needs of hotrodders. Try convincing someone that a fpc or cpc can live just fine with boost, they'll tell you every old wives tale of why only a cpc can. Like I said though, hellions already made 1080whp with 17psi (at peak, 19psi around 4000rpm but the tapered down to give it a massive midrange of 4500-7000+ making 1000whp). Additionally, Henessey has a whipple supercharged setup on 7psi making over 700whp while keeping the fpc, and even dropping compression 1 full point! That graph looks nothing like the turbo cars, but it's also be no where near as stressful on the internals. [/QUOTE]
