Well, I played around with the spreadsheet from Joe Lubrant and made a few changes/additions. :biggrin:
One of the changes is the the BSFC. It is my understanding that "charged engines" are closer to 0.6 BSFC, vs the 0.5 BSFC that was in the calculation. This has a HUGE affect on injector sizing.
The "new" spreadsheet allows for "user input" of the BSFC variable.
In addition, trans gear ratio and TC slip were added.
Remember, this is a guideline for estimating!
Joe still deserves all the credit.
I just did some "tweaking".
Try it and see if it works.
