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 ? :(

Thanks for any help you guys can give me.

I ran that pump with 1000 HP and it was fine. Was rated to 1100 I beloieve under forced induction.


What injector size, fuel line size, etc.? I have run that controller and I have run the boostapump, but never together. I would think they were compatible if wired correctly, but I would call KB and Aeromotive to be sure.

Hey Jody -
Thanks for the info.

I have a -12 feed line to the pump, a -10 from the pump to the front, and a -10 return line. Dan Meyer at RCI is welding on the -12 and -10 fittings in place of the -8's that normal come with the cell. I think Tom said he was going to see how 96 lb. injectors worked.

So, did you have any problems with your pump in continous street mode ?
Did you mount the pump in the trunk area or underneath ?
How loud did it seem to you ?
Did you use Aeromotive's rubber isolation mounts or some other mount ?

Thanks Again Jody. :)

I am just building an almost identical setup: -12AN to a 12302 prefilter, 11104 pump, 12301 post-filter, -10AN to the rails and -8AN return. I will likely go with their pump controller as well.

Does anyone have any photos of an A1000 or the 11104 pump mounted in a '69 Camaro? I was just under the car, and there aren't any blatantly obvious mounting choices.

Thanks!

I like how SW mounted his fuel system in his 69. Maybe we can get him to post a picture.

For what it's worth: when I was at the PRI show in Orlando, I spoke with one of the top Aeromotive technicians, he told me flat out if I tried to run the 11104 for more than 1/2 hour continuous (street use) without the controller it may boil the fuel (and possible cavitation) which really shortens the life span of the pump. An A1000 is a lot more forgiving.

Unfortuantely at that time I didn't know about the pump booster to get his input.

How much power are you making? I ran a stainless undercar tank so the pump was also under the car. I mount all my pumps with rubber insulators, similar to what MSD supplies for their vibration-proof ignition mounts. They really aren't loud when mounted that way. I was also running 95# injectors.

You want the controller period. It will have trouble on long runs without it!

Hey Jody -
Don't shoot me, I know it sounds overkill, but Tom feels that at low boost the motor will be around 1000-1100hp. High boost could be 1500-1600 which is part of the injector equation. The high boost is if I can occasionally hook up with slicks at the local dragstrip (Orlando Speed World). I still have some 1/4 mile blood in my veins and as much as I love PT for the overall driveability, I can't stay away completely from the drags.

I know that you own/have owned extremely high powered cars. Quite literally your yellow 69 with the D1SC 540 was my inspiration.

Who is SW? Sorry, I don't know everyone here yet! :-)

One thing...the 1500-1600 hp figure I threw out is to make sure I have a good safety margin for the fuel capabilities of the pump. Whether those numbers are real will be for the dyno to decide.

I do have one other question though - As far as you know, is turning on a "second" pump always additive ? Let me rephrase that - if you have, say, an Aeromotive A1000 and the Aeromotive Eliminator, do both pumps put out the same pressure for a given voltage, and when used together they can flow the extra volume necessary ?
