Cheap increased flow from your TII fuel pump?
Guys, offer me your opinions/personal experience; Kenne-Bell, the supercharger manufacturer sells an accesory for his supercharger kits called a Boost-A-Pump. From what i see and understand, it is some type of driver adjustable voltage/amperage amplifier for the fuel pump, thereby increasing its ability to flow at a much higher rate. Kenne-Bell says that it can do this without extra pump heat (which would compromise the pump life). Any thoughts on this, and how hard it may be to build? I've got moderate experience in electronics, but i wanted a second opinion.

does it amplify the voltage above 12v? it might only do the same thing as bypassing the resistor set and giving the pump permenant 12 volts.
post up if you find any info

I use the Kenne Bell Boost-A-Pump in my FC.  I love it; it eliminated the requirement to heving to rewire my fuel pump power wire.
The Kenne Bell Boost-A-Pump comes with a boost sensor.  This boost sensor keeps tabs on how much boost the engine is seeing.  It also comes with an adjustable ****, calibrated from 12VDC to 16VDC; this allows max voltage output from the unit.  You splice the Boost-A-Pump into the fuel pump power line.  Once it sees + pressure from the boost sensor, it'll start rising fuel pump voltage to maximum to whatever you dialed the adjsutable **** to.  Kenne Bell claims their unit can induce most electrical fuel pumps to output as much as 50% more capacity.  An electrical fuel pump is not voltage regulated, so the more voltage you supply to it, the more fuel it'll flow (within reason).  I've been running my unit for the past 4 years with no ill effects.  There is also a way to set the Boost-A-Pump to a straight (adjustable) voltage regulator by removing the boost sensor and shorting the two wires - this lets the Boost-A-Pump set voltage full-time via the adjustable **** regardless of engine pressure.
Priced around $200, I highly recommend it to all turbo FC's.

The Boost-A-Pump makes SURE the Walbro gets full voltage.
An upgrade fuel pump is nothing without proper voltage.
Some will argue the higher flowing fuel pump will compensate for any voltage drop in the fuel pump power line...you make the gamble.

So Ted, I assume you have the 20amp version? Also, does anyone know if when operating within fuel cut (<8.6psi) does the car still have a drop in fuel pressure. The reason I ask is that with my stock s5 turbo and a 40mm tial I can hold boost under fuel cut with a 3" and TID. I'm planning on getting a better intercooler and adjustable fuel control (either afc or maybe save up for the haltech). I'm just wondering if this boost a pump will have positive affects on my fairly stock 88 t2. Lastly, without a haltech how else can I control timing once I go above fuel cut with a fcd. I know the J&S has the ability to retard timing with boost....is there anything cheaper? Cuz eventually I want to really take the boost up..but I don't want a new engine in the process...catch my drift. Thanks fellas.

I have the Gen II version.  The Gen I version is a nasty looking expoxy potted unit - I got one of the first red extruded units out.  I know Kenne Bell has multiple (amperage) versions out now.  And yes, mines is the 20A one.

has them cheapest around I think - high pressure, shipped for $122, lower pressure, shipped for $107.
