[QUOTE]Originally posted by st5150: [QB] 66 AC COBRA of long_name: 255 lph will provide enough fuel flow to support 550 rwhp on that motor. If it truely makes 550 rwhp, that'll be about 1.3 rwhp per cubic inch.... so far for a NA motor, Mike Camara holds the rwhp per cubic inch record with a tad over 1.2rwhp per cube. So after putting things in perspective..... crazy efficient NA motors like that tend to make more rwhp per same quantity of fuel. The BSFC goes down in other words. Maybe to 0.45 or so. Keeping BSFC at 0.5, and all the other variables the same as above, but using 42 lbs injectors at 40 psi, you'll be very safe to 500 rwhp. Keep those 42 lbs injectors, but calculate a drop the BSFC due to the motors super efficiency and you'll have plenty of fuel for 550 rwhp. Keep in mind that the injectors were never pushed past 85% duty cylce in these calculations. So like Bounty Hunter vert said: run what you have since it sounds fine, and if on the dyno you find out otherwise, upgrade the restricting part of your fuel system. [/QB][/QUOTE]
