Why isn't a Boost-A-Pump or MSD more popular here?

Sorry, I thought I quoted SDB when I posted, guess not! ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
But thanks for your info too . . . I wonder @ what rpm I'll run lean without the BAP, and then how much extra I can get by using it.

People tend to think of voltage step up boxes as a sort of bandaid. But it's far from a bandaid. For cryin out loud the pumps are all electric and need power to run. If you have to supply voltage why limit your self to 12-14 volts!
I used to run a small dry cell 6 volt in series with the 12 volt car batt for a total of just under 22 actual volts to the pump. I had it activate the high volt setting by a simple WOT switch and spdt relay wired to the pump. It was all posted on the now long gone tech-ls1.com
Total cost of the setup was maybe 35$ including the battery which lasted what seemed like forever without a recharge.
The fuel increase even with the stock vane pump from a 98' was DRAMATIC when it got 22 volts to it. The pump never failed after 100's of runs with the high voltage as it only saw the extra Volts for a max duration of a 1/4 mile run.
I still have the pump sitting in my tool box.
Before I'll ever waste any money on a voltage step down box for my current aeromotive to make it more street friendly on hot days, I'll install a good intank and run my old DIY battery in series setup again.
I have tried 3 fuel pump setups now. ( Many more but we'll keep it to this car.
)
stock pump with ~22 volts,
dual intanks,
Aeromotive external which is the current setup.
The voltage boosted setup worked best for street duty IMO.

Any one know what sponsors sell the KB Boosta Pump???? I am wanting to run one with my setup...... Does anyone know if ill have a problem with voltage if i move my battery to the back.... it comes off a Optima Yellow top now and in 0/1 gauge wire and into a 15 farad cap. From there i have 10 gauge wire feeding my pump being turned on by stock relays.... If i move the battery to the back i would think with such a large cable (0/1 gauge) i would have little if any voltage loss and just run a KB boost a pump to help me out.... what ya think.??

Thats some good info to know.... So the MSD uses a boost Ref. then?? If so how is everything routed??? is a n extra line for Boost ref. run all the way to the back of the car?? Thanks

Okay how about some finalizing for a customer.
Already have your 99' PnP Kit, MSD BAP, Aero FPR.
Your install on the fuel pump is awesome, great instructions! That's done. Now I need to route the harness...seems pretty simple, Power, Ground and a piggyback on one connector near the top of the tank. Where I'm a bit lost is where the BAP plugs in (heard it plugged right into your harness!). There is a single power wire "jumped" in the harness...I figured that has something to do with it but there is only one assy to make a similiar plug in the kit. The BAP has a Batt-Red and a Batt-Black.
Do you have a schematic or instructions for the best way to do this or could you give me some brief instructions.
One more question...any problem mounting the BAP under the car behind the the rear seats where the factory "T" block is....car does not see rain very much if at all.

Both grounds from the BAP go to a good chassis ground!
The red wires are fitted with the supplied connector set and plugged into the Racetronix harness. Battery side is towards the relay. BAP is fitted with male connector on the battery side. Female connector towards the pump. Keep the BAP power wires down to apx 8" in length.

Thanks for the quick response.....shouldn't I have two connnector assy's then...sounds like the BAP runs in series (between the Battery and Relay on the harness) with the harness. After that chassis grounds and a boost reference and it should be good to go. Let me know if I'm on track.

The BAP grounds go to chassis not the Racetronix harness.

Sorry...went and looked at it again in between posts....I do have both connectors...makes more sense now. Let me sum it up and tell me if this sounds right....
when I'm complete (assuming I locate the BAP near the factory "T" as I stated above) both red wires will be plugged into the Racetronix harness and they will be less than 3' long each, the chassis grounds can be put anywhere near by and also be relatively short. The only wire going up to the front of the car should be the Batt Red for the Racetronix harness. Then I just need to route my boost reference line. I'm I correct?

3 feet not 3 " inches...but I understand your point. It will probably end up 1'-3' on all wires near the back of the car. Thanks for all your help!

If there is enough wire you can run the BAP grounds to the same bolt the Racetronix harness + relay uses. Solder all the connections and coat them with the supplied grease to prevent corrosion.
