I got a 14b on my ride and was wondering whats a good boost setting for it. Right now im running 15psi.

let me know what you guy think

 

15 psi on a stock fuel system?

 

i would put a wideband on there to know where youre really at and you can tell if you can handle more boost that way.

 

thanx i was just wondering if i could turn it up, i got a 16g at home and just wating for the my fuel pump and fuel pressure reg.

 

I would think 15 would be high on a stock fuel system. what kind of FPR are you going to be running ?

 

my friend ran 24psi on a stock fuel system.... you just got to look out for fuel cut

 

 

^^ Not necessarily BS, I've seen it done, not the smartest thing to do but has been done. The limit I would like to say is 22psi safely if boost cut doesn't hit. The 1g is more forgiving when overboosting, I would atleast put a walbro fuel pump in and you will be fine. My X ran 20psi on a 14b and no issues. It now has a 16g on it at 15psi and is running rich. I will be turning the boost up to 18psi to see if it balances out.

 

what car did your "friend" have? a 1g or 2g ?? what turbo?

 

He had a 1g with a 14b

I also did it on a 1g with Walbro and a mitsu Garrett -24/14b custom turbo from Dave at Majestic Turbo.

My GSX has a walbro 255, FMIC, and when it had a 14b I ran 20psi, I will more than likely be there again with the small 16g thats on it now. I wouldn't dare go higher than that without bigger injectors and safc hooked up. With the 14B it would hit 20psi and drop down up top to 18-19psi and hold! I also have a potientiometer in the car which should make it run leaner but it seems to make the car run richer. I also run a 6-bolt 1g engine in my 2g
