Homemade Turbo Build fuel problem :( (video up)
#41
I watched your video. A very nice build. I love budget builds. One thing I noticed was when you rev your engine, I hear the engine and not the turbo. Now I am still pretty new to this myself so take my info with a grain of salt. Anyways, once I get mine to around 3k in rpms you hear the wizzing of my turbo's and not the engine.
Like this.....
I didn't hear this in yours. I also have my pumps set up so the first pump runs all the time and the second pump kicks on with a hobbs switch when I hit 4lbs of boost. Not sure if any of this helps but wanted to comment just the same. Good luck and great job.

How is your fuel system ran? Do you have the pumps on all the time or is the second on a hobbs switch? How did you set your base pressure for the regulator? Did you adjust the ifr and offset tables for your boost ref regulator?
I will say that with my setup, I set the base pressure and at an idle the fuel pressure is lower than what the base pressure is. It's the base when it's at 0psi and then goes 1psi up for every pound of boost.
It sounds like you have a problem with the way the regulator is setup. Maybe in the tune as well if you didn't change the appropriate tables.

You should worry more about load situations then just revving it. You should log what it does while you are driving. I'm sure you'll have more problems then.

So then why add a turbo if you aren't going to need more fuel? You should need the second pump and you do need the regulator installed.

i have 3 255's there isnt a problem running my single the way it is on 5lbs of boost. and yes i have driven it plenty of times and like i said before once it gets over 2500 and into boost fuel is perfect a/f ratio is dead on as well so thats not the problem and no i dont need a regulator for one walbro.
