I just noticed many of your posts are about Vishnu, are you an employee there? If so what is your take on why your booster pump is better than a upgraded in tank pump? Those booster pumps used to come with Vortech supercharger kits for GM trucks but everyone would throw them away eventually and put a Walbro in the tank??

The suction valve at the bottom of the assembly is not regulated at +70 PSI in factory form. Pushing the pressure through it up that high is going to cause failure at some point; but i have no data on that point currently. To add to this note, there is also no sealing surface for it to be completely "fuel tight" at the base when held on by zip ties. -- Imaging having a huge boost leak all before your throttle body because you didn't feel like putting a clamp on the coupler. You would be able to hit boost certainly, but with very little wow effect; and all that leaking boost out of the system is going to cause the turbo to have to work harder to maintain pressure. As a result, it may over-run, and fail prematurely. Another note, the leaking boost around before the TB is also going to cause your boost to fall off at higher RPM as your turbo falls out of its efficiency range. -- Remove the word turbo from all that i previously mentioned, and sub in fuel pump. Remove 'boost leak', and sub 'fuel leak'. Remove TB, and sub 'before your HPFP'. I think you get the point. The DIY procedure is going to essential cause a fuel leak in the low pressure system which makes the pump work harder, and also causes loss off efficiency as pressures go UP (and the pressure in the LP system is much higher than most any other vehicle in production, period.); this is why you want to leave the stock system intact. The booster pump will NOT cause a leak, and will ONLY raise fuel volume flowing to the HPFP. It gives you complete peace of mind when driving your car on long trips because you know that your stock siphoning valves and fuel regulated systems are 100% fail proof, and that your fuel gauge is accurate. |

Last thing, its already been demonstrated the DIY E85 Walbro holds LP at 100% ethanol and 500+rw on RBs (demands more fuel than single turbos). In fact much past this you will see HP start to fall, indicating the $200 DIY eliminates LP issues. I guess once we see more details this pump setup could look better, but so far I am unimpressed. I have been waiting for a LPFP upgrade and was honestly expecting a lot more than this. Not just a copy of the DIY Walbro slapped on top of the stock unit. I will wait a little longer for more info and results, but its not looking good! |

DIY are seeing. Overall it's been a solid low fuel pressure setup. Different strokes for different folks. That isn't to say your inline pump can't be a solid setup either. With inline pumps normally they reduce volume / increase wear on the in tank pump when they are not pumping, becuase they become a big restriction. Does yours pump full time or only during wide open throttle? Mike |

But just remember Vishnu had been working on this far far longer than when that DIY popped up. A lot of R&D has gone into this and the other fuel system components soon to be discussed, I wouldn't throw this out as a viable option just yet.

To answer a few questions.
Many people were wondering how we were supporting the fuel system on Shiv's car earlier this year. Now everybody knows. We were actually running a prototype version of this system at the shift sector event back in February and have logged approximately 20k miles. This is a heavily tested product. This has played a crucial role (not the sole reason by any means) in Shiv's car producing over 600 whp on our mustang dyno on 100% e85 without changing methanol nozzles. Our inline fuel pump remains intank so there are no issues with the pump overheating. The installation of the fuel pump leaves all factory siphons intact and does not obstruct any of the fuel level sending units. The fuel pump remains on at all times running variable voltage and reducing the strain on the factory fuel pump. The efficiency of the Walbro fuel pump is increased at high fuel pressures because it is being fed instead of actually drawing in fuel. Shiv and I have had several conversations with high performance fuel pump engineers on this topic. I will post this in the other thread as well.

This is a short video I put together for the single turbo system that has a few clips of single turbo powered 335's at the shift sector event.

Unfortunately I do not know. I only received the videos titled as (car description) vs (car description) as the name of the video and a text document with notes on how the car was performing during each pass.

I think we all need to wait for the 6AT fix before we assume what a Single can do vs an RB car. The singles are being dialed back due to the Trans at this point.
Just imagine a 650whp with a 6AT that holds the power. |
