Thank you for adding this to my search and I will definitely look at it. But i am just wondering what the voltage has to do with the pump (walbro or aeromotive). It was delivering 16 Volts to the walbro with the kenne bell why not 13 Volts to the aeromotive.

 

This is a photo I found from the past. Do you reckon I need to replace the red wire going to the fuel pump 5p connector or I need to replace wiring inside the fuel filter set too. This photo is for illustration only I do not have the BAP right now

 

What he's saying (if you remove the boost-a-pump) is to run 87 all the way to the pump (not just to the stock wiring on the plug or pump housing)

 

Thank you. I did a little search and I found a topic he did in the past

Id1000 injectors can make a lot with high pressure. I have made 600whp on e85 with them and 750+ on non alcohol fuel. Your best bet is to run a second pump inline to help boost the pressure.

Lowering your pressure is not going to gain you anymore headroom. Once you max the pump out at a certain pressure the pressure will start to drop. Starting with a lower pressure will just make it maintain the lower delta pressure across the injector without dropping, but you still end up with a low pressure so injector duty will be high.

The OP doesn't need to run the base pressure at 65psi that is unnecessary The injectors are large enough for anything a 35r can deliver, and the fuel pump can as well, just not at the fuel pressure the OP's system is trying to achieve right now. The fuel pump can supply 200 more hp worth of fuel at 70psi vs 90psi. Why not start 20psi lower instead of adding a fuel pump and keep the pressure high for no reason.

What you are saying is if you run the injectors at 100% eventually the pressure will drop low enough that the pump will supply enough fuel? That is what you don't want to do hence lower the pressure and deliver a linear fuel supply without any pressure drop while still meeting the engine's fuel demands.

 

What I am saying is that if the pump is already dropping pressure and the injectors are hitting at 100% duty cycle then dropping base pressure is not going to make the pump flow more. It will just create a more linear fuel delivery like you said. If you are already hitting such high duty cycle then you will need to add pump capacity to make more power on those injectors or switch to bigger injectors and lower the base pressure.

 

Just a small update. It took me quite a bit of time to do the update but due to my newborn son very little time to deal with the car.

Well we played yesterday with different base fuel pressures in the FPR from 2.5bar to 3bar and 3.8 bar only to see there were only minor changes in the injectors performance. So problem still there. Injectors max out too early. Can't even run the high boost I was before the problem with my FPR appears. So definitely is not that the injectors need upgrading. I have not upgrade the wiring from the relay to the new Aeromotive 340 pump though but I have the feeling is not the problem. Car was working fine before with the stock wiring having the walbro connected with the kenne bell. Do you reckon that there is a possibility my injectors need cleaning and can create the problem?

Thanks
