14b --2g max boost---IMO

[pickens]

I was reading threads about 14b's on 2's and I hear people saying it is safe to run around 18-20psi on pump gas. IMO, that would be safe on a 1g w/ lower compression, but on a 2g I wouldn't reccomend it unless you were logging. If you have a 14b on a 2g and you run 18-20psi daily then feel free to chime in and dispute, every car is different.

There is no way I would run that high on a 2g with stock fuel system.

I have a 14b on my 2g with a 3kgtvr4 fuel pump and am pulling .96.94 o2s at wot with boost set to 15psi. I might try to up the boost a bit, but not too much.

big16g + AFC + walboro 255

18psi

.96-.98 depending

i ran close to 23 at the track on 100 octane.(save the your a retard comments im buying injectors in the next week)


local guy was running 20psi on a 20g, front mount. he figured out he was at 80% duty cycle with his EMS...did i mention stock injectors?

socalieclipse runs 15lbs on his 20g with stock injectors

as long as its in the turbos efficiency range and your not detonating who cares right?

so i say boost 20psi and when your stock injectors split in half grab some better ones

yeah, i got a 20g with stock injectors.
It depends on when you say "stock fuel system" though
I have a walbro 255lph and SAFC so I have some control.
I run about 12psi normall and 15 when I'm getting on it. It still pulls pretty strong with 15psi, but I'm running pretty rich too just to be safe. I have my AFC set to +10% up top and somehow my injectors keep squirting more fuel out. I logged it the other day and I was running .97-.98v from 5k-7k at WOT

I think that you should get a logger and see how much you can get away with. Every car is a little different. Your injectors might be clogged or worn so you might not get as much boost as someone with better injectors, or whatever...
Good luck

I run 18 daily on a 14b with stock injectors. Rewired, steveteked 190 and GM maft (leaned out 5-10% depending on the day) is it for the fuel.
