Fuel pump requirements
What do you think the minimum pump is required on a car that goes 10.66@128. W/a 1.55 60ft. 3200lbs
This is a bracket/street car a friend has. |

Re: Fuel pump requirements
something like a Holley blue pump will get the job done. 1 gallon in 30 seconds is the flow you need on a car of that speed.

Re: Fuel pump requirements
Mechanical or electric?
My street car is 3260 w/me in it, runs 10.60's @127 and has a regular old Carter mechanical pump with 3/8 lines.

Re: Fuel pump requirements
Funny how things change with the times. Is that 1gallon measurement thru 2 needle&seats at full drop?

Re: Fuel pump requirements
Fuel pumps are rated at free flow, so if you take a Holley blue and with 3/8" lines you hold the out line in a empty fuel can and run the pump for 15 seconds you should see slightly less than .5 of a gallon. This is adequate for this combo, but IMO borderline. I would use a min. of 250 gal/hr pump. Remember that line size, bends in the lines, filters, pick up location from tank, fuel regs, and fitting choices among other things can reduce the actual flow to the carb. Take caution when checking free flow. No burns....

Re: Fuel pump requirements
It surprises me that theres no mention of g force on the launch, thats the whole problem with a 12 PSI fuel pump. Theres a reason bigger pumps run over 20 PSI out.

Re: Fuel pump requirements
He's running a single blue now.
I had freshened the engine after it ate a lifter. Upped the comp to 11.1,had the heads ported and upped the cam on his request. Only picked up 2mph from unported heads a point less compression and a cam that's 7degrees smaller on the intake lobe. Sorta looking for answers i guess. |
