I read an article online last night that a fuel pump for a 12 sec car should be able to fill a gas can within 35 seconds. I have a Holley blue pump that's rated at 110gph and I did the math and broke it down for how much it pumps in 35 seconds and it came out to 1.06gph!

If I'm running mid-high 12's, is that cutting it too close.....if that flow chart I saw is accurate?

I ran an 11.34 with one.

I would say yes it should be more than enough...I have seen some very quick cars running the holley blue pump.

So are the pumps rated at a free flow rate because once you start adding pressure, the flow rate goes down. I'm dont disagree but if there are cars running a lot quicker than 12's with a blue pump, then the flow chart I saw is incorrect then.

rated at free flow .
don't know if Holley still has the red street pump...that is all you would need

So if I do a flow test, I should test the flow AFTER the regulator and not before it to have an accurate test?

You are WAY over thinking this the blue pump will be fine for your car.

before the reg .
line size is also a factor

like said , you are over thinking it . get a fuel pressure gage . at WOT if pressure steadly drops , then there is a volume problem in the system

I run a Holley blue pump, 3/8ths line including the tank pick up tube. I leave my regulator set on 6. I had to fabricate the tank pick up myself. My car has run 11's but is in the low 12's right now.

I run the red pump on my Ranger, it's rated quite a bit less than the blue pump, and I'm running high 12s.

Yeah, she'll be right mate. My 4 door, 3550 pound Falcon did high 11's on Holley Blue and 1/2 lines, and i only have a Mallory 140 at the moment and run 10.7's with that set up in the same car/same fuel lines etc.

I ran mid 12s in a 3700 lb car with a high volume mechanical pump with stock lines. You will have NO trouble with the blue running into the 10s I would think.
You will need larger lines, like 1/2 inch to go that fast but the pump will be able to keep up.

Already have 1/2 fuel line with sumped fuel tank.

I have a friend running two blue pump with a 496bbc and he is running 9.80.s
