What fuel pumps r u guys using?
I need a high flow EFI pressure fuel pump for my Catalina. I need it to supply 50+ psi and up for a turbo install. Horsepower wise it must supply possible 1200 to 1500 HP and my 2000cc injectors. It is also a full street car and would see miles on the road. So it has to be hardy enough for continuous use. I'm also looking at E85 although our area just changed over to E54 (damn it) but I could also require it to run alcohol.
I'm OK with electric or if I need to, go to a belt driven pump. Any insight you guys have or direct experience with these higher HP pumps that you can recommend to me, it would be much appreciated. Thanks. Mark

I run two electric pumps, a smaller one for driving and trying to help keep fuel temps in control and a big Aeromotive pump when in boost.
Moving large amounts of fuel all the time will heat the fuel to boiling and that will cavitate a pump to ruin. |

Anyone running the Holley twin pumps? They have a big one but do not recommend it fir any street use, especially in temps over 90 degrees. The Holley 200 can be run as one pump and then your system can activate second pump when needed. But I'm afraid the 200 will not flow enough????
Anyone running belt drive pumps on the street? I've got a 150A Hilborn pump but I'm not sure how they stand up to street miles? I would have to find out what psi the pump makes at lower rpms also. I have to be sure I have the minimum (50ish) psi at idle. I'd prefer to run an exterior pump too. Not sure I want to go into my fuel cell to modify it to run an in-tank pump/pumps. But it can be done if necessary. Mark

Race pump is a Waterman Mini Bertha, second pump is a Prodigy 42402 which has a built-in speed controller that can be an external source like Holley Dominator EFI.

I have a belt driven Weldon pump, after needing to add a second electric to keep up.
Have a Waterman cable drive with a Weldon mechanical, which is made by Waterman and private labeled. Give Jim at Weldon a call. Great amount of knowledge and very accommodating.

Mark...give Hilborn a call http://hilborninjection.com/ they can tell you what you need to know about your pump .
BTW they are also a dealer for Weldon and Waterman products |

Nothing that would work on your car Mark. I'll try harder next time around.

You should use a fuel pump controller on the street. Aremotive makes one. It PWM's the pump when fuel demand it low and increase as fuel is needed. Keeps fuel temps in check for street driving.

I pulled the plug on a Magnafuel 750 on E-Bay. $437.00 which I thought was a great price (free shipping). I was looking at Magnafuels site and they do not recommend pump controllers, at least not for their units? I was surprised to see that. Not sure where I saw it but it was because of the strain on the pump at lower voltages. Or I think that was it. Causing damage to the motor? This pump is good for 20-120 psi and it's supposed to supply enough fuel, boosted, for 1600 hp. I think I'll be good, LOL. Or, the motor will hit 1600 HP---once---and the pump will not matter anymore! HA!

Mark. You should call them and ask them about a pwm pump controller. It does not lower voltage to the pump but instead sends a pulsing current to the pump of 12v at diffrent duty cycles. Aremotive does not suggest a controler for there pumps that regulates current either. That is why they developed the pwm controller. On a side note i have ran an A1000 with e85 for over 2 hours of highway driving with out having fuel heating issues.

I used an A1000 on my turbocharge '73 TA too. It ran fine. But It does not move enough fuel for my needs on my current car. My TA ran a CSU blow thru 850 carb and the A1000 worked great. I do remember reading about the new controllers pulsing the pump too but I forgot about that until you posted it. I may look into it. Thanks for the heads up and reminding me.
Mark

I had the complete Weldon set up on my car before the upgrades. It did have the Pulse width monitor (PWM) as well, the purpose was to Lowe the pump speed while having enough volume to run the car in street applications. All the pwm does is lower the pump speed in order not to overheat the pump while on the street.
A great setup but without a second pump just wouldn't keep up with E85 with the cars power. Combine that with the noise output with a second, I went cable drive.

1600 HP would rip my poor bird in half. Are you bringing that thing to Pontiac Heaven Mark? I wouldn't mind seeing it make a pass.

another option is to talk to Josh Davis at Fuelab. They have great products and even better service.

I plan on running two of the "Bosch 044" fuel pumps that do not drop pressure at high flow demands. They will be installed in a Surge Tank at the front of the vehicle. Plumbing from the surge tank will go to the Engine Fuel Rails/Regulator and return to the Surge Tank.
A pair of the Walbro / TI Automotive TIA485-2 F90000267 Fuel Pump 450LPH fuel pumps in the Tanks, inc fuel tank will feed the surge tank. The Walbro and Bosch 044 fuel pumps will be staged as far as fuel pump demand on what pumps are on and when. The engine will be a boosted engine configuration but will be street driven with one tank EFI pump and one surge tank EFI pump "on" at lower HP levels. Tom V. I have been stuck on the road when a single efi fuel pump set-up died.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
