Ive been trying to research online but can't really find much. Is there a specific formula or anything I should be considering when deciding what size DP to run? Obviously every car is different, but it seems like most people just run a certain size and end up changing it down the road and seeing how the car responds. My build is a built 2v 4.6, 10:1, TF 38 cc heads with MHS stage 3 turbo cams, edelbrock manifold, and E85. Planning on the turbo setup to consis of a PTE 7675 CEA and CG Fab hot side. The hot side comes standard with a 3" DP, and I will most likely just run open DP. Does anybody have any thoughts if the 3" would be good enough or should I look to be going bigger? Goals for the car are 800+ through an auto.
