Where do you find specific BSFC Charts?

I just got a 2017 Kia Forte5. One thing I'm curious about is optimal acceleration to maximize fuel economy.

I've seen multiple references to the use of Brake Specific Fuel Consumption charts for determining the optimal acceleration for select engines.

Question is...where do you go to look up BSFC charts for specific engines, like the 2.0L 6-speed used in the 2017 Kia Forte5 (and Hyundai Elantra)?

Thanks in advance,

There's a thread specifically for people posting charts they find. I don't think there's any single good place to find BSFC charts, so we scavenge and infer.

Yup pretty much. I usually go: 1. NA? 2. Cylinders? 3. Liters? and find a similar chart for a similar engine. This will usually get you a pretty close curve and rpm plot to drive by.
