So, if was to put together a 408ci with a gt42-78t, i believe it has a AR of 1.01, what kind of diameter piping should i run for a crossover and DP? I have been looking around and packaging is important as i would like to keep the a/c, for example, so i fifured a 2.5" crossover and a 3.5" DP...
How about that AR on that turbo. I know that flow through the motor is a key factor, my current 408 has GM 6.0L heads with 2.08/1.60 valves, not sure but flowed over 320-330 at peak and mid lift was quite thick. Also, the current cam is a 246/248 .613/.615 114lsa installed straight up.
What do you guys feel with this turbo/AR combo, my powerband will look and feel like? Should i expect a punchier mid section or a all-of-a-sudden boost hit?
