Turbo 4.6 on 5 psi of boost
Hey guys,
I have had a nice quality turbocharger laying around, it is a little big, but will do. My goal at first is to run 5 psi of boost just to get the truck up and running. I am guessing that will yield about 50 hp. My question is, will the stock fuel system, injectors and pump, allow me to run 5 psi of boost of will I have issues. I just planned on getting and adjustable FPR since it is such low boost levels, until I got a tune.
Thanks

Are you stating facts? Do you have personal experience or know someone who has run 19# injectors with an FMU on 5psi of boost that had major issues? I'm not trying to say you are wrong, I just would like specific issues you know of that happened, not here-say. I have found a half dozen 4.6's that ran up to 7 psi on the stock 19# injectors. This is my DD so I wont be running wide open all the time, I have probably only shifted wide open a dozen times since I got the truck 6 months ago. So the injectors wont even see that kind of abuse very often.

Why do companies make FMU's? Why do companies sell them with turbo/ supercharger kits? They work, not as good as a tune, but they work. And when I am trying to create my rear mount build on a budget, that is the method I prefer. My only question is would it work, not do you think I am rigging my setup. Thanks

They make it, so it must be good, right? It sounds like you've already made up your mind, so as I said before, good luck.

I'm a kid now?
To answer your question, running 100% duty cycle, with a BFSC of 0.65, 300hp (at the flywheel) requires 24.375 lb/hr injectors. Running the injectors at an acceptable level (85% duty cycle), you'd need 28.676 lb/hr injectors. But what do I know?
If you want to buy a Kenne Bell FMU, I have two of them sitting here brand new in the packaging.

Running an FMU will work Ok if your factory air meter doesn't run beyond the range of the ECU. If it does, then the motor will go lean in a hurry, plain and simple.

My first blower kit was an AED (Allen Engine Development) kit with 5 PSI and used an FMU with the 19# injectors. No computer tuning.
Did it work? Yes.
But it worked a lot better when I upgraded to 42# injectors and a 90mm MAF with a custom tune.
I have since moved on and am running 60# injectors( different setup) and still get 14.5 MPG on the highway.
Good luck .
