Hello! Does anybody know where I can find a BSFC chart for a 3.1 LH0? If that'* not possible, then I would accept a 2.8 or 3.4. Any help would be greatly appreciated! Thanks!

what is bsfc

Justin, I believe the member is referring to a Brake Specific Fuel Consumption Chart.
AutoSpeed - Brake Specific Fuel Consumption

Brake specific fuel consumption. Here is an example chart from a Saturn 1.9l engine: http://ecomodder.com/wiki/images/3/3..._dohc_bsfc.jpg

Edit: someone beat me to it!

As far as the graph is concerned, they may be one for the Corsica 2.8 using Google for instance.
There are other ways and calculators available online to produce a graph?
If you know what the horsepower is and fuel in pounds used per hour, you divide the pounds per hour of fuel used by the engine HP which = BSFC efficiency number that would appear on graph.

Arian are you trying to determine if you have an engine performance or gas consumption problem ?

Nope, I'm trying to determine the most efficient operating range of the engine.
