In my thermodynamics class we dabled with a GM Quad 4 on a dyno. We were using the Otto Cycle and comparing it to actual analysis from the dyno and calcs. One of the parameters we found was the BSFC (brake specific fuel consumption) i found this one pretty interesting and was wondering if anyone knew what the LS1/LT1 has for BSFC. Also if anyone has a P-v diagram i would also like to check that out if you don't mind.

thanks

 

BSFC varies with engine load and rpm. I found at the final tune on my 381 setup the BSFC for N/A tuning was around 0.45#/HR/HP. For a big hit of nitrous, it was 0.52. You can see how it varies with rpm from the dyno sheet below.

Can't help you with the p-v diagram.......
