It's a valid lab result of how pumps work which you have clearly shown you have no clue. Other than a pressure regulator, Terry's testing was in an unrestricted environment and doesn't take into consideration restriction. A pump is a pump. I have always agreed that the walbro upgrade is a great solution for someone who wants to break apart their stock LPFP and replace it with a better pump. Although the FFTEC option cost double, it's plug n play and can be reversed quickly. As the graph indicates and is consistent with Terry's finding. The only thing he left out was the head. Dynamic Chang as pumps have to work harder or have increased restriction. So regardless of what you think or say, we now have three viable options thanks to Tony. I applaud everyone who brought the solution to our platform. Last edited by Wedge1967; 01-19-2013 at 02:04 PM.. Reason: because ing335i is a _______ |

Just a thought from a non-engineer. While i think the test was good, i don't necessarily think it is conclusive. The test basically measured max flow potential, but the purpose of an upgrade is not to max the system. The purpose is to support x flow requirements. The series test may have been outside the efficiency range, similar to a turbo choking... Its going to overwork itself. A parallel test would be to run all pump options at various flows and then measure current draw. This would be interesting.
As it stands now though i will be purchasing the single pump when needed. |

For someone like you who has paid $600 for this FFTEC pump I understand why you feel so strongly for it, but what are your thoughts on the proposed $100 alternative solution? A walbro 255 pump in series that improved the factory pump performance by more than 50%? It goes in just as easily. |

To be fair, the FTEC costs tripple, not double.

Put a parallel pump setup on a high restriction system and you may as well be running one pump because you'll still have pressure drops on surge. The chart is going to be the same and you can go find 10 more charts just like this in different senerios that will have the same outcome. So, do you need to sustain pressure or increase volume or both? You seem to know alot, please tell us oh so smart one? The only solution that does both is series and if you can't see that then you are dumber than I thought you were. Bottom line is we have three options on the table. They are all viable options depending on your needs and we won't know how parallel pumps stack up until someone drops that solution in a car and tests it. I hope it works and can sustain the pressure drops on surge. So before you keep spouting off like you are so smart, why don't you go do some testing and get back to us on how your parellel system works so much better. I recalling you once said or maybe more than once, that a single walbro would out performed the pumps in series. Even Terry's data proved you were wrong. So who is full of hot air? |

I only paid $475 and that was installed. At the time, the other option wasn't really on the table. So I will say it again so everyone can hear me one more time, I think all the options we have are viable. I have and will recommend upgrading the walbro single if they want to go that route. If you want a plug and play option and you don't care about the price, then FFTEC has a good solution that works and will maintain pressure under surge. Story is still out on parallel. Because parallel doesn't raise the head, only increases flow. Also as indicated parallel is not recommended in highly restricted systems. So we'll see. I can tell you that the series solution works. That is why feel so stongly about the solution because I'm using it and it works. So when someone tells me it doesn't have to wonder where they got their information. Anyway, it doesn't really matter. Regardless everyone will form an opinion, just don't cast doubt on a solution that works just because you don't like the vendor it's associated with. |

Lol, whatever makes you sleep at night. Fact of the matter is a $180 pump does what you paid $475, $600, $whatever for. Still waiting for your "lab results". Parallel was the way to go, not series. Like I have been saying from page 1.

I do agree that all options are viable. However, I think the issue is the way Shiv was presenting/ not presenting his information that is making people irate. Shiv was so stuck on his way is the best as seen in his posts and now we have some hard data and people can make there own decisions.
FWIW, I'm glad to see things advancing with the platform and really don't care for the political aspect. So fight on! |

Shiv said his solution works well and also Terry has proved it.
It seems some hate it because they hate Shiv. Not too rational. Adding e85 Walbro inline flows more than replacing the stock pump with the e85 Walbro. Lol at the pricing discussion. If I'd sell a replacement kit with info, support, installation manual, warranty, storage, capital cost requirement for the working capital, credit losses etc I'd ask $500 for it. So please do not compare a kit price to a non-kit price. If you don't have the money or just want to save, you can do the inline kit yourself. This is supposed to be a technical forum, so please get your price discussions elsewhere. |

Wedge is there anyway you can post logs of some 100% E85 and 100% Meth runs? Also of some 100% E85 no meth runs...
No dog in the fight just looking for actual data...

Well, it's a little cold outside today for pulling logs and Tuesday it will be raining. Let me see how tomorrow afternoon turns out. My wife is working and the kids will be in school, so I'll try to get out tomorrow afternoon to get a couple of good pulls. What information are you looking for? I'll post it up to the virtual dyno thread because it's a little off topic for this thread.

I suspect that any minor low pressure upgrade would be enough to support original turbos. Once you upgrade the turbos the parallel setup is probably going to be the best way to go. Since you already own the pump if you ever want to switch it sounds like you will need only change around a couple of your fuel lines. |

It flows much less than the gains promised in this first post but it does flow better than factory. Testing showed a lot of currant usage with dual pumps. How is this setup powered? Any concern with fuel heating up?
