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.

OK . . . if you get to a point where you can dyno with/without the BAP, please do, inquiring minds want to know!

The BAP he is using is making up for lack of regulation at the fuel rail.
This problem has been covered in the forums here many times before.

Looking forward to the Racetronix FP Regulator.
$ waiting and ready to go.

Yup. I run a KB BAP in my Cobra. I'm not sure why LS1 guys don't use them.

ChevyNo1

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.

where to get a kb bap or other for a good price

MelloYellow

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?

I used one 3 years ago in my first ATI/LS1 car, worked great. Matter of fact I used that plus a HPP3 and a MAFT + 38lb injectors with the stock PCM and ran 11.30 @ 122mph in a full weight f-body before LS1 edit existed

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.

Thunder Racing sells the MSD booster.

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. "

I know I'm bringing this back from the dead . . . but I'm upgrading to Mototron 60's. So:

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:

The BAP goes from 0-50%. Assuming my pump is currently seeing 12V, then I only need to boost it by 15% to see around 13.5?

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.

Racetronix

iTrader: (2)

A Racetronix system w/BAP will provide more than enough fuel volume to support 650RWHP BUT as stated many times before the regulator must be relocated to the rail to get rid of pressure drop. It does not matter how much volume your pump can supply at a given pressure if the regulation point is at the back of the car in the tank!

So are you saying to dump the factory regulator and put it at the rails and then with a walbro pump setup and a BAP it will hold 700+rwhp. Wont you still have to run a return line?

I just put one on my LS1, seems to work fine. With my 382 stroker and 150 shot, I was running lean. I put on the KB unit and a FP gauge on the rail...idle it is 59-60 psi, then when I turn the KB unit up to max, the psi goes to 65+ on the gauge at idle...seems to increase fuel a lot. Hope "blowing" through the regulator is not too bad for it.

ChevyNo1

At what rpm were you running lean?
