Quote from: tmsmini on August 19, 2020, 02:30:13 PMI am no expert but I am not sure you can compare the diameter of the FI system directly to the diameter of the carb system. Basically an HIF 44 is 1.5 inches.SC offers both 45 mm and 50 mm TBs. It is not clear to me at what point you need the 50 mm TB. The Rover MEMS MPi system used a 48 MM TB and Burlen offered a 52 mm upgrade. I am not sure the MEMS 2J could effectively use the 52 mm version.Certainly the ability of the system to flow air is limited by the diameter of the throttle, but the ability to use the air flow is dependent upon the other components in the system. I am just not sure how to know when the extra flow is needed.
