Since I'm in the process of rebuiling my 2.0 engine, I was wondering why 914 high performance engines use 44 IDF carbs instead if 48 IDF's or IDA's. I'm not trying to build a race car or anything to much but want to upgrade my 40 IDF's.

I'm not trying to build a race car or anything to much but want to upgrade my 40 IDF's. Because the 44s make more power and yield better efficiency. I START using a 48mm carb at 2.7 liters of engine displacement, below that the 44 will kick the pants off the 48. I've ran them back to back on dozens of engines. For a carb to work well it must "Carburate".. Big carbs don't do that very well. I can count on one hand how many times "bigger has been better" out of hundreds of experiences, even on large engines. |
