id like to see racetronix do something on this, last time i emailed ur address, you said it could not have been the pump. and we went back and forth. i just gave up. you said it was the install..

how can we prove its not the pump? would u like ECS to test it? would you like to test it?

i mean this is my second pump within in 1500 miles. the first one **** out right off the bat.

i do thank you for helping me point out some factors as far as the fuel issue..

 

I Too just had a well known pump go bad

Had it replaced and all is fine

Wish they could have helped me also


Oh well i guess I got 1 yr out of it

 

I would like to see an independent company test it, I'll send the crate of other bad ones here as well.

 

I can assure you Doug wont let you hanging ! ! He is a great guy to deal with and always taken care of his customers ! !

 

2 things as stated

1) don't drive like that especially don't get on it at all

2) tune wouldn't have changed, but in that it is based on say 58 psi and you are down to 48 or 50 psi, you are lean..big time and at the worst time...wot

While you can probably get away with just a pump, or pump and bap, thinking ahead, it may be just throwing good money away if you up the boost down the road.

In any case, your current problem needs to be addressed first and foremost.

Fuel hydrolock, if that was one of your initial problems a while back, would be my biggest concern.

Good luck with it and let us know what happens...



btw: hope you are not too far from ECS...they'll fix you up...

 

i go almost every week to hang out with the guys, i think they expect me to come anyway with some kind of part to install

 

I've already eaten the cost of 2 of those unnamed vendors pumps - and I've only been in business a few months...

 

I guess Iam to hard core. If a company is having problems with their product why should a vendor get stuck with the bill?
No company has every built a perfect anything everytime. If the company doing the manufacturing of a product would be made to stand behind their product they would be a lot more interested when something went wrong.
So here I am getting ready soon to upgrade my system and no one want to state the truth about who is having the problem.
You don't have to do any bad mouthing anyone just state the facts. How will the rest of the forum members feel knowing several people have information that there is a problem but won't say who the problem is with. If I choose the wrong system and it turns out to be the same system you all knew was having problems I should I feel about you?
I don't want to hang anyone, I just want some one to be accountable that should be accountable.
I have already been through BS with Lunaiti. They had a problem with the wrist pin holes in the pistons that came with my stroker kit. I did receive new pistons, a rebalanced crank, and shipping was paid. But the tear down and reassembly was on me. (from short block back to short black) Was it my fault? NO. Was it my techs fault? NO
(I got real lucky he seen it when he did or I would have been out a lot more money then I was.) But it does happen with every company at some time or other. The manner in which it is handled makes for a repeat custmer or NOT!
I thank the forum member stating he feels he has a problem with his Racetronix pump. I also want to thank the Racetronix supporting vendor for stepping up to the plate and helping what he can at this point. He has a valid point of wanting to make sure it is a pump issue and not another issue causing it to seem like a pump problem. (Bad electrical connection voltage side or ground side causing low voltage at demand time? Fuel restriction somewhere? who knows at this point?) But once all checks have been made and if it turns out to be a pump issue then Racetronix needs to pick up the tab. If they don't they should understand why NO ONE buys their product anymore.
Thanks everyone for letting me vent.

Well I'm at the crossroads and don't know what to do. My friend and I ordered (2) ECS novi 2000 kits (they look great) and guess where we are on the install? You guessed it, the fuel pump. However, my concern after reading this thread is that the kits come with (1) Racetronix and with (1) BAP. So now what do we do? I was going to put the Racetronix pump in my car because my friend had a full tank of gas and I was on reserve fuel. But if i use the BAP on my 99 that is 8 years old and has 100,000 miles on it, what will the increased voltage do to the stock pump

 

We source the pumps from LPE and have made them aware of these ongoing issues and provided them links to these threads. We are now waiting for them to step up to the plate and help us with these issues. We have yet to send a pump back to LPE and have it confirmed as being defective. We have been told Walbro does not have a performance guarantee or warranty on their HP pumps which is somewhat understandable. Unfortunately without a performance spec. and tolerance we are unable to run our own in-house tests.

There is not enough margin in these pumps to be sending them out free of charge to everyone who suspects theirs has gone south. In most cases there is nothing wrong with the pump. We would like to have LPE work with us to put together a simple test procedure that most customers can run with basic tools and a reliable mechanical pressure gauge. This would most likely be very similar to some of the GM service manual info. If someone has a questionable pump we can provide some basic test info and if that does not work we can submit the pump to LPE for testing.

There are many people running on the fine edge of what these pumps can support. Some people are able to get more HP support w/o running out of fuel because of their combo but that does not mean the next person will be able to support the same HP. The average C5 HP level now is much higher than in 1997 but the HP pump has not changed. Perhaps our FI customers should consider our DP system which can support upwards of 1000HP. A BAP and a harness can only buy you so much headroom and they can not come close to the performance of adding a second pump.

 

Are these the same LPE 255 pumps Andy uses in his kits ?

I'm kinda confused, if one pump goes bad, how does having two help if you depend on the volume of the two combined and one malfunctions. It would seem that you would be in the same predicament. OR, are you saying that using a BAP puts you on the ragged edge because it overdrives a pump beyond it's original design ?

Does Racetronix condone the use of BAP's ?

 

Wow I think your car is cursed. It seems like you spend most of your time towing it / limping it to ECS.

Boy your cars' Dr. bill has got to be

Hope you get this fixed. I say sell the supercharger, sell the car, and just buy mine

 

These are the same Walbro GRJ420 pumps and buckets A&A uses.

You are assuming all these pumps are failing which they are not. You are also assuming that these pumps which are supposedly failing are doing so without any outside help. Of the few that do fail most are helped along by bad gas or being run dry.

RX DP systems use a different pump and setup so some of the factory limitations are eliminated.

Running a BAP is not a problem as long as it is setup properly. LPE and RX customers have been using them for years. It all comes down to proper installation, application and maintenance. The problem is with customers who do not have enough fuel volume so they use a BAP to get them just over the edge. What the fail to do is leave a safety margin. In our opinion there should be at least a 20%+ buffer between what the motor needs and what the fuel system can provide.

 

not to make this some sort of challenge or make history here.

but i will be towing my car to ECS on friday, how about we send in my pump and a few others they have that have failed to a 3rd party, to test?

if they are not failed. i will pay for the testing.

is that fair? this way, we can at least have real live results to this pump issue. i think @ 350.00 a pump. vs. half that for testing. itll be well worth my investment.

not saying the product is bad, but u could have a bad batch

 

You would have to find someone who has a test jig for the C5-specific pump so they can test it in its bucket. The jet-pump functionality must be tested as well. There is no guaranteed performance spec from Walbro so where does one draw the line? 220 / 210 / 200 LPH? Assuming your pump did have a problem how do we know there is not an issue with the system in your car which is causing it to fail?

You problem sounds like it is related to the fuel moving around in your tank. If this is the case then most likely there is something preventing the bucket from working properly. It could be something as simple as the bucket's checkvalve, a pump that is not seated properly, a lose wire, etc.

If you would like to test your pump then why not send it into LPE?
