I was just finishing my "must have" list for my fuel set up. I am going with 1000cc primary and 1600cc sec. injectors . I do have the cosmo fuel pump , but the MSD fuel pump booster was recomended .Are any of you guys using this with your single set ups ?

I dont know of anyone on the forum running pump boosters. I do however have a lot of friends that run them in Mustangs, Fbodies, ect ect ect. They all run the "Boost a Pump" from Kenne Bell

i run the kenne bell boost a pump. it is a super unit and just what i need to assure that i have enough fuel under boost w my cosmo pump. it is very well engineered and they have an excellent website. i mounted my unit next to my battery which is located in the pass side package compartment behind the seat. i also mounted my adj dial there and just reach back from the driver's seat to turn up the gain. i have enough stuff around the dash...
the boost a pump employs a solenoid you mounted in the eng compartment that switches the unit on once it detects boost. zero to 50% gain. i looked at both units and picked kenne bell after talking to them.
a neat thing about it vs running a huge pump is it doesn't constantly recycle gas to the motor and back heating it...

$200.

One thing to consider is that some FPR's have a vacuum line hook up which when they detect boost, it will add fuel to compensate. I'm not sure which system would be better, whether the vacuum line is more accurate or if the dial would be better to meet specific needs.

All FPR's have a vacume line (for forced induction cars anyway) but that has nothing to do with a Boost a Pump. You run them both. The boost a pump just gives your fuel pump extra volts so it'll pump more fuel and you dont loose pressure.

Also, it keeps the voltage regulated and rock solid. I thought about getting on just for that reason alone

Okay but a fpr regulates fuel, so as long as the pump is up to standard if once you get into boost the fpr should be able to compensate for it. If your fuel pump can't supply the required amount at a normal voltage, then a pump booster just sounds like a surrogate.

The boost-a-pump just increases the voltage which increases pumps capacity, it's a perfect solution if it's reliable. Not too different than rewiring around the stock circuit to get another 1.5 volts, it simply allows one to dial in the amount of voltage increase and even better it only works under boost. If I run out of pump tuning past 19 psi I will put one of these units on my system.

SnowmanSteiner

Okay I'm sorry that makes more sense. I was thinking the boost pump gave an extra amount of voltage to compensate for the fuel pump, not to just make it push more. But still to me it sounds like a bandaid. I would want a pump that was supplying constant pressure that wouldn't need to compensate if under boost. Again that's just me.

If you called up Kenne Bell (creater of boost a pump) and told him that he would tell you that running a larger pump is going to put more heat into the fuel. You pump runs a full capacity all the time and your pfr and return line is what depermines the pressure. If you run a larger pump then that means when your cruising, at idle, ect your sending the majority of the fuel back down the return line and your big giant fuel pump is just recirculating all that fuel and heating it up. He would tell you with a boost a pump your not going to recirculate as much fuel and your not going to heat it up as much cause your running a small pump.

The recirculation part is correct, the part about it heating up the fuel to much.... I dont know. I guess its possible but I dont know how much effect that has on performance.

I do know gas starts to boil at 95F so I guess its possible for the heat to create a problem

Thanks for the feed back , it was recomneded by KDR , but not as a "must have "

SnowmanSteiner

Does anyone else have more information as far as the fuel heating up and possible negative side effects. Also how much hotter are we talking about here? Another thing is even if the fuel is getting a little hotter it's going back to the tank, so it will pretty much only be getting warmer for a little bit than cooling right back down, unless the return line goes straight to the pump where it would be recirculated again. You must also consider that the fuel is traveling at a fairly quick rate, so you would imagine that any heating up is going to be momentary. Let me know on some of this stuff. I'm still debating on what I think of this idea. Thanks
