TurboNova Posted March 5, 2011 Report Share Posted March 5, 2011 Anyone running twin a1000 pumps? What kind of power are you able to support and what regulator are you using. I have 1 a1000 eliminator pump but thinking about getting a second a1000 and just running 2 a1000 pumps instead of having to boost voltage to one pump and making it work hard on e85. Need to support 700whp e85 but want it to work for upto 1000whp. Not too interested in a cable drive at this point Quote Link to comment Share on other sites More sharing options...

TurboNova Posted March 6, 2011 Author Report Share Posted March 6, 2011 Already have a1000 eliminator it would be cheaper and possibly better to get a twin setup going but just looking for any feedback Quote Link to comment Share on other sites More sharing options...
AJ Posted March 6, 2011 Report Share Posted March 6, 2011 IPS runs twin pumps on their TT vettes. why do you need twin pumps? the one pump should be more than enough for that power level. the eliminator is good to 1400hp on forced induction EFI. so when you factor in the the about 30% more fuel the E85 needs and that that pump will support 10% more than its listed for you should be fine. depending on your time line i may have a solution to your fuel system.

TurboNova Posted March 6, 2011 Author Report Share Posted March 6, 2011 Interested in your idea. In theory the eliminator pump would be good for max 800-850 whp e85. I was thinking running one additional standard a1000 pump then join both pump feed into a y block -10 feed single line to front then y out into rails. Just to keep the one a1000 pump from getting hot from being overworked Quote Link to comment Share on other sites More sharing options...

TurboNova Posted March 6, 2011 Author Report Share Posted March 6, 2011 Do you have twin feeds to the rail or is it one feed Quote Link to comment Share on other sites More sharing options...
AJ Posted March 6, 2011 Report Share Posted March 6, 2011 on marks car each pump feeds one rail. Quote Link to comment Share on other sites More sharing options...
AJ Posted March 6, 2011 Report Share Posted March 6, 2011 i don't know if all of my system is going to work for you. the way it is right now with the pumps i am working with it will only support 960hp with 10% safety margin. and thats on gasoline not E85. i'm not sure if the system will work with the aeromotive pumps because i don't have any to test with.

Mattsv8 Posted March 6, 2011 Report Share Posted March 6, 2011 Nope never heard of such a thing. Twin a1000s. Na don't do it. I made 762 on e85 wheel at 15lbs with a single 8yr old a100. Your elem pump is more than enuf for that level. The twins would b good beyond 800 wheel hp Quote Link to comment Share on other sites More sharing options...
Buckeye1647545503 Posted March 6, 2011 Report Share Posted March 6, 2011 Can you just run a boost a pump to bump voltage to give you a little more room for safety ? Quote Link to comment Share on other sites More sharing options...
Mattsv8 Posted March 6, 2011 Report Share Posted March 6, 2011 u can but a correctly wired pump should be on a relay at the pump so its getting whatever the battery is charging at. pics http://i33.photobucket.com/albums/d71/Mattsv8_03/SSPX4768.jpg http://i33.photobucket.com/albums/d71/Mattsv8_03/SSPX4769.jpg notice the top first design pump. yea its still working i had a new a1000 fail within the first two passes of its life? supposed to be better but i dont kown we will see how thisone holds up Quote Link to comment Share on other sites More sharing options...
Ackbar00 Posted March 6, 2011 Report Share Posted March 6, 2011 I am switching to a Twin Bosch 044 from a single A1000 and I know several guy on turbomustangs running twin pumps without issue. If it makes you feel better to run twin pumps then I say go for it. Quote Link to comment Share on other sites More sharing options...
TurboNova Posted March 6, 2011 Author Report Share Posted March 6, 2011 I cant say that it makes me feel better to have twin pumps but I guess the rest of my car as I am building it is ready for that next step if I take it there so I did not want to have to change anything except for injectors if I step it up hp wise. Matt are you running seperate feeds to your carb or is it one feed Quote Link to comment Share on other sites More sharing options...
Nate1647545505 Posted March 6, 2011 Report Share Posted March 6, 2011 How about we chug some numbers and find out what your fuel demands really are? What kind of pressure do you plan on running? Boost? 1:1 Regulator? DT loss? Quote Link to comment Share on other sites More sharing options...

TurboNova Posted March 6, 2011 Author Report Share Posted March 6, 2011 Alot is undecided at this point. The car is not really a setup others have done as far as engine combination. It has a 1:1 regulator, running e85. I will be running between 12-18lbs of boost. I am running a th400 so figure 15% loss. Base pressure maybe around 40-50psi?

Guest Spam Posted March 6, 2011 Report Share Posted March 6, 2011 Woah, Thats a huge difference there. That fuel pressure difference alone can jump you one fuel pump size itself... let alone the difference in boost. Quote Link to comment Share on other sites More sharing options...
coltboostin Posted March 6, 2011 Report Share Posted March 6, 2011 Single Eliminator will be enough for both of your goals, but if you want to waste some money, grab a second one! Quote Link to comment Share on other sites More sharing options...
Nate1647545505 Posted March 6, 2011 Report Share Posted March 6, 2011 (edited) Alot is undecided at this point. The car is not really a setup others have done as far as engine combination. It has a 1:1 regulator, running e85. I will be running between 12-18lbs of boost. I am running a th400 so figure 15% loss. Base pressure maybe around 40-50psi? Rock on. Let's start: We'll average a best/worst case conditions: A) best case 10HP is produced from 1lb-min of air 15% DT loss 1000whp * 1.15% DT loss / 10 hp per lb-min= 115lb-min Air Req b) worst case 9HP is produced from 1lb-min of air 18% DT loss 1000whp * 1.18 DT loss / 9 hp per lb-min = 131lb-min Air Req Averaged, that's an air req of 123lb/min to produce 1000WHP. We now have a starting point of air mass, all we need to do is calculate fuel mass. If you re-arrange Air / Fuel = Ratio, you can determine Fuel = Air / Ratio. We need an air to fuel ratio before we can continue. We know that E85 has a stoic of ~9.8, and we'll pick a safe lambda of .79 (roughly 11.5:1 on a regular gas). Our ratio would then be 9.8 * .79, or 7.74 parts of air to 1 part fuel, 7.74:1 AFR. Plug and chug, 123lb-min air / 7.74 air/fuel ratio = 15.89lb/min of fuel req. Since everything in the fuel world is generally done in pounds per hour, convert by multiplying by 60: ~ 954lb/hr of fuel req. Finally, to convert to volume flow, you need the mass per volume. For E85 (and gas), that's roughly 6.5 lbs per 1 gallon. So, 954lb-hr / 6.5lb-gal equates to ~147 US Gal / hr. Converted to LPH, ~557LPH.

Nate1647545505 Posted March 6, 2011 Report Share Posted March 6, 2011 From Aeromotives product page: http://aeromotiveinc.com/products-page/fuel-pumps/11101-a1000-fuel-pump/ http://i54.tinypic.com/2m2hro5.jpg So your rail pressure at max is going to be intake manifold pressure + base FP,landing you somewhere in the 60-70psi range. As you can see, @ 13.5V the A1000 won't be able to supply 954lb/min in the 60-70psi area. Quote Link to comment Share on other sites More sharing options...
