Check Your FuelIn the Dec. '07 issue on page 51 ("How to Design a Fuel System") you have a formula for gallons/hour that seems wrong (I went back and forth between it and several other calculations, since I had not seen the formula before this article). I think the formula given does not need the factor of 2 at the beginning; just HP times BSFC divided by 6 equals GPH. Otherwise, thanks for a good article. I'm building a '66 Chevelle with a 454 bored and stroked to 489, topped by an 8-71 blower and twin 750s. Maybe 900 to 1,000 hp! -Gersh Lundberg, Paducah, KY What we didn't explain very well is that the multiple of 2 in the equation (2 (flywheel hp x 0.5 BSFC/6 = GPH) adds enough pump to compensate for friction in the lines, g-forces, low system voltage, and whatever else might conspire to starve the system for fuel. The industry uses it as a safety measure.
