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

And how much is it??? If it only helped for 25 more HP then it isnt worth it............. or is it??

Kyle, I THINK it was around $300 . . . I've got one but haven't used it yet. I hope to use it and get some advantage when my 370 shows up . . . it's shipping today, FINALLY!!!!

Car is still being tuned. Shredded a belt today. Switching brands. Had to ugprade injectors, etc etc.
We're close to maxing out the S-Trim, Close to maxing the injectors. Etc. We've been changing too many things in this setup to be sure of anything other than we max'd out the 42# SVO's.
We were just starting to dial-in the Motoron 60# when we lost the belt.
With LQ9 heads and 1 3/4" headers the 42# made 575rwhp at 6000. Now with the AFR 2-5's and 1 7/8" we're making that power level at 5000-5500 and the injectors can't keep up.
Since changing belts and tensioners we are seeing more boost now also. Too many variables.

This problem has been covered in the forums here many times before.

Racetronix, what are you talking about? I'm talking about the boost-a-pump, not what you're talking about in that link . . . unless your product does the same thing. From what I understand the BAP just provides a constant voltage to the pump as well as makes it pump more . . .

They're talking about their new FP regulator solution.
At the moment our problems were running out of injectors and I think the Wideband on the dyno is shot.

Bought my KB BAP via A&A in Cali.
Think the MSD one is a bit superior. Would need to compare them if I was buying again.
Racetronix:
Are you considering a Rising Rate version of your FPR?

mototrons are OEM quality, and anything outside of 1.5% (if i recall) is scrapped. so the simple answer would be YES. they are not grouped and sold in sets according to how far off spec they are.
racetronix.. two gss340 pumps at 13volts through one -8 (3/8 ID) hose.. how much hp/rwhp can it hold.

Our FPR ad states:
"Use of the pressure port for manifold referenced fuel pressure will extend the HP support of existing injectors and allow for the use of extremely large injectors while still being able to maintain decent idle and driveability characteristics. "

What RWHP do you think I can attain with stock fuel lines/rails, these injectors, the intank Walbro 340 and a BAP?
I'm specifically wondering how much the BAP will help because on your site you say:
A Walbro pump's average fuel volume increases over 18% by increasing the supply voltage from 12 to 13.5 volts.

These question have been around for a while. I am using a MSD BAP w/stock pump. Not holding up to what I need it 575 @5100 rpms and loosing lots of presure I have ordered some stuff, but wanting to know if a walbro 340 or their plug and play thing will provide a better supply of fuel or what I mean is do I need to keep going in the direction of and exturnal pump etc... I am not wanting to but I will if that is what it takes to get a reliable fuel supply to my motor for the HP numbers I am tring to get safely.With out running out of fuel. All I see if people guessing so I am wanting to know MelloYellow is what pump are you running and is it providing enough fuel for your S/C motor. I know mine works but under a lenghty time (DYNO) in the upper rpms it will drop rapidly.
