Hello, I was hoping someone could help me out with some dimensions for the Weber 40DOE or perhaps others. I am building an EFI intake for a Formula SAE car. I'd like to purchase ram pipes (velocity stacks) rather than machinging my own. The Pipercross rampipes are sold for the Weber 40DOE, 45/48 DCOE, 40DHLA, and 45/48 DHLA. I am wanting to use these bolt-in ram pipes on 1.5" OD and 1.42" ID intake runners. So I'd like a range of 35-40mm for the ram pipe outlet. Any help is appreciated Charlie Ping
