Mech Fuel Pump Drag Racing 318
I am running the Carter high flow fuel pump and that will show a short coming in round robins (back to back) runs with the vehicle slowing down a tad. This is on a street driver, not a race car. Two different fuel needs and requirements. Both can do a good job in feeding enough fuel but one is simply better at it and does it consistently.
REALLY! In a drag car, if you MUST run a mechanical pump, that’s one thing, but if you don’t have to, run an electric pump. Now everyone can cry there to much money, there more complex, and cry about having to run a regulator and return line. Fine, make all the excuses you want but an electric pump with a regulator and return line is what you should be doing at a minimum!
How complex after that basic set up you go is on you.
The bottom line in drag racing is ether consistency or flat out speed. Both are achieved best by a electric fuel pump. There consistent on keeping the fuel there, more reliable bowl fueling and making more power. That’s just the bottom line, sorry.
