Does anyone have any definitive calculations as to what our BSFC(Brake Specific Fuel Consumption) is for our engine with an equal length manifold and very efficient turbo setup?

I have a range of .50 to .60 but need an exact number if anyone has ever figured it out for a FI F20C.

This will help.

I have this info also but I am trying to find out the exact BSFC of our engine with FI and this is too far of a range. Some sites say a turbo car is .50 to .60 and some say .60 and above. But if you do airflow calculations (which is what I'm trying to do so I can plot a good turbo for my setup) using just a .05 change, it makes a huge difference.

This is why I'm hoping that someone has the exact number that has been calculated.

Thanks

On a Lovefab GT1 that I did the number was around .54 Of course this was done by calculating 15% drivetrain loss and assuming fuel was static at 47psi, so don't take it as a final number...just referance. Hope this helps.

Yeah that helps some; thanks.

Hopefully some others will chime in and confirm also.
