Fuel pump booster

has anyone thought of or actually tried an electronic fuel pump booster on the ms3 yet? Its like a fuel pump amplifier that works with the stock pump and does not effect the longevity. The stock intank pump only get around 12volts at wot, many people have logged a drop in voltage when the sputter/fuel cut happens. Witht his device you can set it to jump the voltage up to 16-17 volts rms when the unit senses boost. I know these cars also have a Cam driven pump up front but dont you think that increasing the amount that enters the CDFP with increase or at least stabilize the CDFP's output?? i was gonna buy one this week to test out, im also switching to the one step colder plugs with a tighter gap. will post results as soon as i get em, but please lemme know what you think about the Fuel pump booster idea, thanks
here are some linksand lit on a few pumps.
scroll down on the msd site

From Magnuson web site:

A digital, dual-input fuel voltage controller is available for sale individually, and as an upgrade to the Magna Charger line of supercharger systems. The digital function has the advantage of linear power flow and reliability. The Magna-Volt will allow for high-performance fuel delivery based on 2 variables; RPM and boost. When the Magna-Volt sees a predetermined RPM and boost level, it increases voltage to the stock fuel pump to 17 volts at 20 amps. Using 2 variables maximizes fuel economy and pump life, while still allowing for the high performance modifications enthusiasts love. The Magna-Volt will come pre-set and ready to install with wiring harness and full color installation instructions.

Full Digital Operation Integrated digital operation features modern technology.

Dual Input While reserving room for additional input, the unit is currently designed to monitor both boost and RPM, raising fuel pressure only when needed. This method ensures better performance, mileage and long pump life.

Stock pump The Magna-Volt was designed to work with the stock fuel pump, alleviating extra expense and labor.

Plug-and-play Nothing to set or adjust, the Magna-Volt arrives pre-set. Installation harness and instructions are included.

Magnavolt operation description:





Trigger rpm: 3250 rpm +/-200 rpm (115Hz with a square wave form)

Trigger pressure: 3.0 psi +/- 0.250 psi

Voltage when triggered: 17.50 volts (depending on battery voltage)





The Magnavolt can be triggered with only one or the other inputs as well. If you want to trigger it using RPM only, such as a NA application, connect the two blues wires together in the Magnavolt harness and this will bypass the pressure switch. You can also use a external switch in the blue wire circuit to do this as well. If you want to trigger the unit with only the pressure switch, such as a non GM application (Ford) do not connect the white wire of the Magnavolt harness and the unit will default to a zero trigger frequency.

This is a similar product to the Kenne Bell Boost-A-Pump and the MSD fuel pump voltage booster - BOTH SELL FOR OVER $225.

This is the same fuel pump booster used in the Magnuson Products supercharger kits for the C5 and C6 Corvette, GTO, CTS-V, CK trucks and many other applications.

Lingenfelter Performance Engineering has voltage boosting on fuel pumps, especially the Walbro/TI Automotive gerotor style fuel pumps, for years without any difficulties. We have performed durability testing on these pumps at elevated voltages of up to and over 17 volts.

Voltage boosting is an easy way to increase fuel pump output only when needed (when in boost) without having to change your fuel pump.

I think the electric inline fuel pump should work. But the pump booster is not designed for "no return line" fuel systems. I think that is what the ms3 has. Correct me if I'm wrong.

well they work great on the new vettes and they dont use a return line. does anyone have schematics of the fuel system on the ms3? is there a built in regulator in the tank that regulates pressure to the cdfp?
 
Stock pump is about a 155lph according to testing by Kinsler, and the in-tank regulator lowers the pressure from 71psi down to 65psi.

Look in the link you posted. It has a note after the booster description, that says "Not for use on Pulse Width Modulated EFI systems (no return line)"

yeah i think thats the msd version, i installed one of those before on the new c6 and it burned up after a few days. the magnuson version is supposed to work with our cars and the new vettes according to a rep i spoke with.
 
i guess just installing the walbro 255lph would be better than a fuel pump amp cost wise. has anyone installed a larger walbro pump yet?
 
My fuel cut hasn't come up since, even with 19-20psi of boost in cold-ass wheather. Only other mods I have though are cai, bov, ebc, and tbe. Fuel cut might come back if I start throwing more stuff on there. I had to do quite a bit of modifying to make it work, but I'm pretty descent at that kind of thing. Someone else tried it after me and really ****** up his car. Then someone else tried a different pump that fits better and ****** up that pump, so... The one that fits better costs $275 though. And either way, there is a specialty tool required to open the gas tank that costs $260 from mazda iirc.

(omg)Are you serious...? $260 for a tool? Is there any other way to access the fuel tank without it?
 
Nope, there are three tabs on the inside of the retaining ring. There must be a certain amount of pressure on the outside of the ring at those three spots to get it to turn. Me and a handful of members on the other 6 forum pooled cash together to get the tool. That was about two or three months ago, and I'm still the only successful one.
