Aeromotive A-1000 Pump

[ONE BAD EXCURSION]

I saw on another site that people are replacing there factory lift pump with the aeromotive A-1000. How many people have done this and what are the advantages for doing this. Thy also said if you put an airdog on that you don't have to do the pre-pump kit. I am trying to upgrade my fuel system and wanted to know where I needed to start.

Get ready to pay a lot for the airdog and unless you are putting out serious power, you don't need it. Pre pump kit and regulated return is what you need.

I've been hearing people complain about the aeromotive pump burning out quickly. How much power are you putting out that your stock pump isn't keep up with?

I was just wondering. I didn't know if it would make a difference on a stock motor or not.

It will always make a difference. But dollar to donut says that a ITP regulated return and pre pump kit will make you extremely happy.

If there is any concern about the fuel supply, put in a fuel pressure gauge. That will tell you if the stock pump is keeping up. Then you can see what pressure you are at and shim the FPR.

I would do at least the the pre-pump mods and possibly a regulated return if funds allow. Then if you still need a pump I would go with either a walbro or Bosch pump. They will fit in the stock location and wiring. The walbro flows 48gph and the bosch flows 55gph. Stock flows 32gph.


To determine the GPH needed use this calculation: By my calculations your 140cc injectors(stock injectors) would be 23 GPH at 2600 RPM. After 2600rpm the fuel delivery decreases so the maximum amount of fuel that can be injected is at 2600rpm.

140cc/1000 (cycles to get the fuel quantity) =.14cc per injection event

2600 RPM / 2 = 1300 injection events per injector X 60 minutes per hour = 78,000 injection events per injector per hour

.14cc X 8 injectors X 78,000 = 87,360cc per hour

3,785cc's = 1 gallon

112,320 / 3,785 = 23.08 GPH

Oh lookie at Mr. Big Brain.


Listen to him.

This dumb redneck knows how to use cut and paste. I have that formula saved in MS Word just for times like this. Copy, paste change a few numbers do a quick calculation and everybody is fooled that I know something.

Works every time.....

[Dirk]

Actually, that in itself is the smartest part.

As soon as I get my tax money back I am going to do the regulated return. ITP is out of the pre-pump kit does anyone else make a kit. My stage 1 injectors are going to be installed tomorrow and I ordered my ts- chip with Tony's tunes. Thanks for the information.
