Lets start a paypal/gofundme for the testing Everyone can throw a few bucks, and I will be willing to build, wire and test any scenario for our community. I am willing to test any pumps as well...I can make walbro ones work by dropping them down into my 55 gallon drum of e85. That being said, the 255 lph are cheap now.

 

Does anyone know if the 450 has an internal check valve? I'd like to stage my pumps in but not sure it will push all out the pump that's off

 

Yes it does. I'm doing exactly what your trying to do. The check valve is right in the pump outlet tube if I recall. You dont need to plumb an external check valve. But I have heard you can remove the check valve from the pump and put a higher flow one in on the feed line and squeeze a hair more out of the 450 pumps...but no idea if thats true or not.

 

Seems Your describing a standard Diesel setup (OEM Dodge) Lift pump in the tank, pressure pump on or close to the motor then the injector pump, some have 2 some have 3.. Might be a cheap trick, go pull the main pump off a 3500 Cummins dodge gas would probably wreck it though..

 

Anybody try a Kinsler mechanical to feed a HP electric at the rail?

 

Any interest in testing a factory pump? Could see the difference vs. the 255 or whatever everyone is going to chip in? I just pulled my stocker and its sitting on the shelf.

 

Got my AEM pumped hooked yesterday and the thing leaks like crazy out of the body. Any one else had this problem ?

 

Any pics ?

I've a pair running on my car, but they seem fine ( well they dont leak lol ), but near sure another user on this forum did say they had the same problem

As for performance, very much undecided on that, although I also made a lot of other changes. The new system does make the strangest noises sometimes though and when making the noises fuel pressure does drop ever so slightly.

 

Don't have any pics right now. A friend of mine has two of the pumps on his car as well and they both sound terrible but seem to hold pressure fine. He's feeding them off a sumped 3rd gen Camaro tank, each pump has its own -6AN feed which is likely too small. Mine shoulds fine but I have it Fred with a -10AN feed off my sump.

 

-6 feed would be on the small side for sure, although if it was a short straight pipe it might just be ok.

 

Got the 3 pumps/fittings/lines ordered to try the 044 clones. Now we play the china post waiting game...

 

gotta love the slow boat....

 

Hopefully these pumps ForceFed86 is sending me can go over 70psi. I am assuming they are selling garbage that they have no test data froma nd that we can get 100psi+

I will start a new thread once I get the pumps and fittings and start building the test stand. Glad we can hopefully produce conclusive data and put some of this to rest for everyone.

 

The more I think about it, the more I feel like I may max out my single 044 pump.

I don't have room to run dual 044s in parallel. Based on what people's experiences in here are, would running two of them in a series give me some more power range/room to work with? I am trying to aim for around ~700rwhp and it seems like the 044 is really in theory good to ~650 crank hp.

 

If you have room for two pumps in series...why no room for 2 pumps in parallel ?

2 pumps is 2 pumps, the plumbing can be routed many ways

650 crank HP is a realistic number, but oddly I do hear people in the US refer to it as a 700rwhp pump.

Nowhere else in the world is it rated for such amounts though

BAP would also give you more headroom with no line/plumbing changes ?

 

We are working some tests now to find out a more detailed answer.

Short answer is yes, but nowhere near as much as in parallel. The lower the pressure the first initial pump can run at, the more it will flow. Series plumbing will still be limited to what the initial pump can supply to the second.

A more ideal setup would be to use a high volume low pressure pump 1st. Then use a series pump to really boost pressure. Similar to the PE 4600 pump. 210GPH at 100psi is nutty!

Because there's not enough room in the factory location on my car to run a parallel set up, but if I run it in a series, I can run the pumps at different locations on the car.

 

you dont have to have them exactly beside each other, but you would want the feed from tank to pumps fairly short, unless it's a good size line. And always gravity feed such pumps

 

The two pumps were basically going to be on opposite sides of the car, roughly 4' away from each other.

 

Again as long as they have a good, clean uninterrupted supply of fuel at all times, no problem.
