View Full Version : High horsepower EFI fuel system Inquiry

I have a fuel system that I have put together for the car.
It is basically an Aeromotive system with an 11104 Elminator pump with a 16032 controller for continuous use. The car has forced induction with EFI. My under high boost conditions, the fuel pump falls a little short.

My questions are:
Has anyone utilized or know anyone that has used Kenne-Bell Boost-A-Pump or the MSD 2350 Pump Booster with the Aeromotive controller ?

For extreme situations, has anyone utilized a dual pump system?

Opinions on which system do you think would be better ? i.e. Overdriving the Eliminator pump for short, high need bursts, OR running a completely separate pump and plumbing ?

Other ideas ? :dunno:

Thanks for any help you guys can give me.

A buddy of mine has a twin turbo, 1200 hp street car that he uses 3 Bosch pumps on. I'm not going to tell you it is a highway car, but he does drive it for extended periods (and runs 9 teens @ 150+!). The pumps are oem for Porche turbo cars.
You could use an Aeromotive a1000 pump with the controller for normal driving, then (in addition to the a1000) turn on the Eliminator pump under boost (without the controller). I think that would support plenty of power.

The Bosch would be a excellent pump for your car to drive, they will support 700hp. On my truck I use one way valves after two pumps. Pump one is always on, pump two comes on above 5psi of boost. This could be done with your aeromotive as the second pump.

As far as you know, is turning on the "second" pump always additive ? Let me rephrase that - both pumps put out the same pressure for a given voltage, and when used together they flow the extra volume ?

Thanks for the info.

If you ran one Bosch, you would be safe to 700hp flywheel. When the second kicks on it would add about 80% of what it is rated for.
I put this system on a street driven Nova, it drives nice and runs 8 second 1/4 mile times. I also installed this system on a 69 Camaro twin turbo car that ran the power tour without trouble. It had trouble the year before with a single aeromotive.

Are these Bosch pumps in-tank pumps?

Originally when the horsepower goals of my engine where higher (850hp) i was going to be running dual walbro external pumps. There are benifits to have internal vs. external.Internal keeps the pumps cooler and externals are nicer when you have a problem. The list goes on.

Walbro and Bosch pumps are used everyday so they are designed to run and run all the time. I know a bunch of hi horsepower cars running these pumps. They are very easy to package in your car and in most cases that is a big deal.

Currently my Walbro pumps are awaiting a new home in a future project unless someone needs them.

I don't know if you are still dealing with this, but I had a question about your question.

Are you sure you are running out with the Eliminator? It's rated to 1100 forced induction hp. If so, I could take it off your hands :)

The issue I see with boosted cars is keeping the correct pressure across the injector. As boost goes up, your differential pressure across the injector goes down if you don't have a regulator that compensates thus running out of fuel. My 2 Pennies...

Hey ron -
Spoke with Brett Chow (sp?) at Aeromotive - very helpful.
He recommended that I run dual pumps - the A1000 pump with the controller ( since it will draw less thus last longer) and then use the Electromotive TEC3 to kick the controller to full voltage and turn on the Eliminator pump. He said that the 13110 Pro EFI Regulator can handle it and was nice enought to send me hand drawn diagrams. Tom Nelson is optimizing and will program this into the fuel/spark curves. [I have to send Tom the whole fuel system since he wants to dyno and tune it with the actual fuel system] A little more complicated than originally anticipated, but an extra pump is cheaper than an engine. Sorry, I would have given you a good deal on the Eliminator.

BTW - from the other thread about your car, that is a sweet ride !!
Sounds like Larry wants to ride again. Also, what model of Corbeau seats are those and where did you get them ? Tanx.

My god...If your using the 1:1 regulator, what size motor and injectors are you going to run with 1800hp worth of pumps. That's mucho' grande' Fuel! Tom knows what he's doing...
I would like to know how others are working this?

My biggest problem is running anything over 50#ers because of being cubically challenged with low compression and a short stroke. I need stockers at idle and 65's at 10psig of boost. How's that for a range.. :hmm: With 45psig rail pressure and a 1:1 regulator, the computer can't adjust low enough for the 50's let alone 65's or more. I had to reduced fuel pressure down to 33 to get the 50's to be tolerable around town. An FMU or a secondary injection system is the only way I know of at this point. Since I will be adding a Cartech FMU, the pressure will be increased to 75-80psig to the rails.(65-70psi across the inj.) My 50's will now act as 65's. With this I will need to add a second A1000 pump myself and stage like you said. These pumps really drop in volume when they see 75+psig. Or I may go with one Pro series and a controller. Do you need an A1000?

How about the Belt driven Pro AEI-11105? 350-2500hp and probably allot quieter then the electrics. $400

Sorry....Seat's are Legacy...Very comfortable

Hey Ron -
Yeah, I am going to need an A1000, another 12302 and 12301 filter, and the -10 15107 one way check valve. Also the 16301 relay wiring kit for the Eliminator.
With regards to your injector sizing/pressure problem, you may want to call Tom Nelson (818)998-5593 and if not Tom, here in Florida there is an EFI specialist - Cal Hartline, (321) 722-1563; www.hartlineperformance.com. Cal is listed in Hot Rod Magazine's article under "Time to Hire a Pro". He has a highly boosted Buick GN V-6 which means his per cylinder cubes are probably close to yours. You might want to give him a call. His car goes like hell.. (In the good sense)

OK Ron,
Call me retarded (because I am :screwy:), but in the pics of your car that Larry posted it says "Corbeau" in big white letters across the back of the seats. Am I dyslexic too ? Don't answer that...

Sorry, I should of clarified it better. The seats are Corbeau, the style is Legacy.

One thing I've found on most of the high end boosted cars is they are typically used for drag racing where cruising around town is not a concern. Idling at 1500+rpm to the lights, hit the rev limiter and your gone. Don't get me wrong, I could put a 75# injector in mine and idle it high and make it work.

I called Tom and ran through my set-up and what I've done. He said I'm on the right path of diagnosing but he didn't know enough about the Accel DFI and gave me another number of a guy who is. Tom didn't recommend the Aeromotive Pro series pump for the street.

Ron -
You still may want to give Cal a call.
He specializes in DFI and FAST.
If nothing else he may say that you are correct.
His car is truly street driven. (not as much anymore, but it was his daiily transportation for years)
And yeah, the Aeormotive guy also said the Pro pump isn't for the street.

I got in touch with Josh (DFI Guru)who Tom refered me to. He's just down the street from Tom. I'll be taking it to him to put in a DFI Dual Sync Distributor, 75#inj and a tune on his chassis Dyno. He say's no problem at idle. I say OK..... :twothumbs

Thx for the input

Now Larry & Allen will really crap there pants :3gears:

Awesome...
Keep me posted with the results and bring some air freshener !
Maybe when I come out for the Dyno test at Tom's place I can look you up. I would love to check out your car.

I am having no problems running 75# hi-z injectors on a street car. They have been easy to tune.

I've seen racers have a 2nd big fuel pump and turn it on via their engine management system at a set rpm, like 4500. Seems like a practical way to go.
