Post 63 & 72.
EFI & carb work on exactly the same principle: pressure forces fuel into the air stream.
- With a carb, it is atmospheric pressure doing the 'pushing'. 14.7 psi at sea level
- with FI [ or EFI ] it is pressure generated by a pump.
Claims of carbs making more hp than EFI [ or vice versa ] are unreliable as to how much hp YOUR combo will make. Too many variables, you have to try it.
