I am going to purchase and install the Racetronix pump and wiring in my '99 C5 in prep for an A&A P1SC kit.
So, I need to order and install the MSD Fuel Pump Booster also...?
Thanks

Before the 97 rail I was having pressure drops at 500rwhp.
I personally think people would be better off trying the fuel rail mounted regulator before they try a new pump.

I have the '97 rail, BAP, and Racetronics pump also (3rd pump of theirs in 3 months). On my system 9 PSI (~4500RPM on COLD fuel) is the max, then the pressure drops like a rock. If I've been tooling around under light throttle for a while 4 PSI is max!!! I understand that there IS a physical difference in the pumps between the two and my next move is to try the LPE and see if there's an operating difference because things obviously aren't working properly right now.
FYI, I have been in contact with Racetronics to no avail and they also told me that Walbro doesn't support their product!
FWIW, a supporting dealer of Racetronics did all the installs and replacements so they were definitely installed per mfg recommendations.

The LPE pump is superior in quality, it supplied my hp without a BAP..fuel pressure never went below 54psi on a hi boost run. Now I have a BAP and will use OPTICZ's adapter/regulator to tie it all together.

does anyone have a fuel system that works on a late 03 car?
a proven system that works all the time every time?
admittedly i dont have fi or any reason to need a hi perf supporting fuel system right now, just plotting out a high horsepower course. finding that there seems to be lots of differing opinions on what system works and also lots of combos that were created to support high hp, but ended up having limitations.
i guess what im interested in seeing is someone able to say if you have a late 03 vette and want 500 hp do this... 500-750 do this...above 750 do this...
or whatever the hp groups there may be.
or are there just too many other variables to have a cut and dried list of options?

I run the LPE pump as well. It is a true plug and play. I have added the relay and draw my power directly from the alternator.
While both these pump are made by Walboro, and are both 255s, there are a few distinct differences.
The Racetronics pump is originally intended for a Chrysler hipo truck package, and therefore the aspirator is 100 degrees off the stock and LPE position. The polarity is also reversed on the RT pump and it has a check valve in it as well....

Changing pumps will not net you any gains assuming your pump is healthy.

I'm not sure what you're trying to accomplish by just running larger wire to the pump? Are you wanting to send more voltage to the pump for more output? kind of a homemade BAP? To be honest, we've never tried this,we simply go the the BAP and wire it up to a manifold press switch, so that it gets full voltage boost as soon as we see +2psi manifold pressure. This works very well, and for higher HP applications, our intank pump is all that's needed.

Call Andy @ A&A and he can better explain.

I have also had a faulty pump from racetronixs, and i think my new one is going also - (dropping pressure at idle after only an hour of driving on a full tank)

850rwhp plus shouldn't be any problem at all with a 97 boost referenced rail, -8 supply, -6 return, hotwire from alt and a KB BAP.
The LPE pump has been flawless thus far.

I think I know where Ed is going here. Replacing the entire fuel tanks and delivery lines and using fuel rail regulator as on the early 97-98 cars. A few of the early 03 cars had the older style tanks with the pump located at the bottom. All they need is the fuel lines, fuel rail/regulator, Walbro pump and BAP. Good luck.

I believe its call HIJACKING a thread.

We have a Racetronix prototype '04 system in a 427 Corvette right now and it's working great. The car is making 525rwhp NA and the pressure is rock solid. We don't have any kind of wiring harness or voltage booster on it, just the in tank pump. With the way the pressure is I would say it's good for quite a bit more power and the booster harness will help it even more.
As far as the other situation goes we have installed ton of the C5 and f-body pumps here in the shop and have never had a single failure. Now I'm not saying one can't fail for one reason or another but I don't think it's a wide spread issue.

Something else to consider LPE warranties their kits for 2/24 year/mile, which includes their pumps.
Maybe other pump makers could offer their pump with a 2/24 year/mile warranty. This would probably eliminate the discussion.

We've done quite a few FI cars, both C5 and F-body.
FYI: The stock pump would not support the 427 in this '03 Z06. Tried it!!!

Why does the fact that it's an '03 explain it? Same fuel system in the late '03 and the '04s.
It a racetronix product so any warranty would go through them but if I install a pump here in the shop then I will warranty it.
