I'm doing the research to select a pump for my SFWD (street-driven) car, and I've basically got it narrowed down to 2 pumps: the A1000 and the bosch pump (the same one in some tt prosches I believe) Goal is to be able to to support ~750WHP

First off, some good background/research threads:

I've done a lot of searching and I've seen some good reasons to go with either one. Here's the concerns I have right now:



1) I've "heard" that the A1000 is picky and can burn out easily without a constant 13.5v-14.0v. With a good charging system, I don't think that will be a problem when the engine is really moving, but I'm personally running a fluidampr (thanks arturbo) with the smaller alternator crankshaft pulley. This means at low RPMs (i.e. idle), I will not be supplying the required voltage to the A1000 to keep it 'happy'. I still street drive this car, and I don't want to burn out the pump quickly.



2) I can't really find a solid flow chart for the bosch pump, and I've heard that it may or may not flow that much more than the walbro 255HP. I don't want to dump a bunch of $$$ into a sump system, only to have similar fuel-flowing properties that I have with a walbro255HP. The bonus to the bosch pump is that (although its around $100 more than the A1000), it isn't as picky when it doesn't have a full 13.5v-14.0v driving it (which is good for having a smaller alternator crankshaft pulley).


Also, how necessary is it to have 2 filters (10 micron and 100 micron) when sumping a fuel sustem?

How much hp can the Walbro 255lph (HP) fuel pump handle? Can it support 600whp?

I have the same thing:

Sup jeromy.

I've decided too keep the walbro hp/255lph and just run a 6AN line from the tank too the filter, and then 8an too the rail. I was going to do just 6an too the rail, but I already had those silver fittings and hose laying around.

I think that bosch pump flows a little more than the walbro at the same pressure. I would ask larry at Endyn about it.

The reason that I've decided to upgrade from the walbro is because it couldn't feed my motor enougth fuel at 524WHP, even with the upgraded power-wire. I installed an additional inline pump to supplement the walbro to get me through the rest of the season last year.

Strange, because people have successfully made 600whp with the walbro.

*Boostwerks*

Damn...thats crazy. I didn't know you did that.

Hopefully mine's fine... :/

Arturbo: would you say that this setup will be sufficient for the WHP goals I've stated above? Thanks!

Arturbo

I saw 700whp with this pump. bosch. You really need to make sure you have a large enough gauge wire too. I think its 12g if I am not mistaen. Servion, I'll IM you back.

Art, How did you have the bosch setup? What size lines as well?

I used a Walboro intake for 600whp+, but I'm building a Nissan with a rb26dett now and going to be making more power this time..

I have seen dual walboro's intake and even three walboros intake for a supra so I might go that route. Also I have been looking into a Fuel Surge tank by using a walboro intank to feed the surge tank and then 2 walboro pumps coming out to feed the motor.

Arturbo

I run the bosch pump and -10 to the inlet of the pump, -8 out to the rail and a -8 return.

That would be loud as all hell... 3 walbros all whinning at the same time...

Art Do u have any pics of ur fuel setup?
I looking to do external pump setup but If I dont have to, it will be better.

SOUNDEFFECTS

Art, How did you do the fuel pickup?

Did you use a sump or just have some kind of pickup line in the stock fuel pump location and then feed the pump. Some thing with the return, just top the top of the pump housing and have it dump back in the tank?

Arturbo

You can see pics of the sump here: http://www.tunerzine.com/artic....html

The sump in the tank was made by Fabman. I had him weld the top part of the tank where the stock pump would go into shut and put a -8 fitting. The sump is actually has a trap door in it to keep the fuel in place when I hit the brakes at the end of the track.

Art Is there down fall for getting fuel from factory fuel pump place. I was thinking about taking factory fuel pump out and welding a -10 fitting with pipe going inside the tank and then -6 for return. I've seen DRT get their fuel from there instead of putting a sump. any info would be great

That will work as long as you run a "sock" like the stock pump has. A sump is used to eliminated the "sock" and it gives the fuel a place to sit t all times.

Turbocivic94

Sorry I'm not familiar with "sock"
Can u please explain more about it

_entropy

If you are planning on running an Aeromotive A1000 on the street, you should think about a weldon dial-a-flow. It slows down the pump at low speeds so you don't overheat the pump or the fuel, and don't burn up the pump.

It's the little filter that sits at the end of the stock pump.

Turbocivic94

I would not run sock instead I would run a filter before pump. Has anyone use stock fuel pump location instead of sump for external pumps.

I'm sure there are.

However, a sump makes utilizing a external pump so much easier. For the pump to run efficently it has to be mounted at the lowest possible point in relationship too where its pulling the fuel from.

This is exactly why farmers will install pumps at the bottom of wells instead of at the surface. same principle applies.

iTrader: (1)

um gettin gready to do the same thing. i was going to get the full reac sump. but what are you going to do with the return line where are you going to put that
