Are you saying your engine builder (and dyno operator?) is trying to tune from the BSFC, instead of the air-fuel ratio?

If so, somebody should tell him to Google "you can't tune using BSFC" to help him understand why that's a flawed approach.


And so does Pettis and EVERY carb on his dyno needs more fuel across the board when in the car and at the track making passes. Afr's to me are the base of tuning then salt to taste from there........That car is a complete work of art............ bow beer
