Flow testing is nessessary and inexpensive. One inexpensive method a small business like FFTEC might use is their shop car. Install each pump solution in car and measure the flow where the low pressure line feeds the high pressure pump. We're talking a couple hours of work here total. |

Bump for an update. I expected with all the ruckus FFTEC or Vishnu would chime in with the data to support their flow figures in the original post or at least promise to substantiate them with real world testing as we discussed above.

I think the lab results support the information Shiv already provided regarding this solution. So I'm not sure what you're getting so mad about? If you're on the fence, by the Walbro e85 pump and do the BMS upgrade. If it doesn't keep up get the FFTEC solution. Simple solution. No point in continue to argue because those who just want to hate on this solution are just killing it for everyone else.

Terry said he made a fuel pump setup and will be comparing the two methods. Though, the one problem is he can only estimate exactly how the vishnu setup is done. I'm still on the fence about it. The only upgrade I need to do right now is the clutch, then a turbo rebuild.

You have the Internet at your fingers.... This is not the only platform using pumps and you can find all kinds of supporting data on the Internet to conclude that pumps in series out perform a single pump. Do you really care? You're not going to buy the solution from FFTEC. But that is only one option, so what keeps feeding the need to keep nagging at people for data when you'll just make a comment to negate the facts. Enjoy the read. Study of centrifugal pump operation in different arrangements by experimental methods |

You forgot to include this part of his quote; "and haven’t had one issue (with the FFtec pump) running 80+% Ethanol content (100% e85) in my car since I had it installed."
This is an important point because Vishnu/FFtec spent over 2 years testing and revising their pump before releasing it for public use. |

Hey, hows the single treating you? Did you do the pump upgrade yet so you can run some e85 with your single? I was trip'n when I got a look at Shiv's surge tank and the fact he was running 100% e85 pulling over 700whp on the mustang. That's sick.
Would have PM'd you, but I figured this thread is about dead so why not .... Also lost my ability to PM, so not much option unless I go next door and post. Hope all is good in the SE. |

If not, I will just wait for Terry to finish his tests. Just looking at the math and data (maybe what you are calling "lab results"), on this forum, others, and other existing platforms, I really don't think the FFTEC pump is a good properly engineered solution. These two pumps should not be run in series for this purpose, especially with such widely varying flow rates. |

I think all jokes should be left aside until Terry is finished with his testing. What is the point of coming back into this thread if you know for a fact you will not be buying the FFTEC pump? To spread your slander and jokes to discourage others from buying the pump? Or are you just DYING to voice your opinion on this product because it makes you feel right inside?

After reading 5 pages of this thread I've come to the conclusion that I'm going to do the BMS style Walbro pump and if that isn't enough or I end up 'maxing' that out then I'll get the FFTEC upgrade.
I don't understand why people are debating this to death. These are two different upgrades that can be run at the same time. Do one of them, and if it doesn't work for you, add in the other one and you should have a pretty stout LP fuel system.

I think it's great that Terry is taking the time to put to rest the flow testing. I just hope he provides accurate results. I already question his testing because he doesn't have that I'm aware of the FFTEC pump to test with. |

Yes I have the pump and yes I recommend it only if you need it. Hell, 90% of the people on this forum don't need it. Like walnut blasting, it's the next hot thing to do to your car... If you are having LPFP issues and your car isn't under warranty and you don't need a booster pump to maintain volume levels required for 100% e85, do the Walbro e85 upgrade. This isn't F'n rocket science people and the two solutions shouldn't be compared, they are options. To be honest, the only reason I didn't go replacement LPFP was because someone else running 100% e85 did the LPFP replacement and even with a new pump they were getting LPFP codes. So I took a chance and paid the money and haven't looked back because I haven't had one LPFP code sense. Yes it's a lot of money if you are trying to compare the two options, but they are not apples to apples so everyone just needs to stop talking shit and just drop the BS banter.

Got it all... Not sure why, but it sounded cool when I bought it. Nice to be able to see the content level, but I run map 4 because meth isn't active in map 3. Pulled some big numbers and put down some hurt at shift sector for just stock turbos. Really looking forward to doing a single. I've drove a few and they just keep pulling. Good luck with the pump. I know the FFTEC pump was a life saver for me. After doing all the upgrades then to have LPFP issues pissed me off because I couldn't pull a 1/4 without coding. You should fly out for the next shift sector and hang out. I think they are planning to go back to the airfield in March. You can fly into Sacramento. Only a couple hours south then.
