I am building a Dodge Rampage, and getting fairly close to having it ready to run at World of Speed. My question of the day is in regards to cockpit ventilation.
I have fixed position lexan side windows, which I have tried to make fit as close to OEM as possible. (there is still a small gap at the rear of the window).
I am using the OEM laminated front windshield. Lexan back window.
I just bought a small lexan NACA duct, with 1-1/8" hose size, which I intended to mount into the driver's side window. Is this enough, should I also cut a hole in the passenger's side rear window?
Am I better off cutting 3" or so holes in both side windows?
As always, any advice is appreciated.
