How much more boost?

[jongreene]

I have the walbro 255 and an aeromotive regulator, my boost is at 15 right now. Without any complications can I up the boost anymore?

I would get a logger before doing so.

I ran 20 psi on my 2g (with a 14b) with a 255 high pressure fuel pump as my only fuel mod.

my friend was running 25lbs with a stock 4g63 but then the turbo gave out you could safley run around 18-20lbs without any problems for a ltitle while

i would stay below 17

at least cop an s-afc before going anywhere over 17 lbs, i would say dont go past 17 lbs. without one

Get a datlogger, don't listen to everbody else's opinons, they don't know what they're talking about.

Grab a logger.

Crank it up 'til it knocks, then back it off 'til it stops.

My car knocks above 14 psi with stock everything, so I would definately get a logger before you consider turning it up anymore. Listen to the two guys above me.

I agree with the logger, but before I get one is there any way to tell if its knocking?

There's the "Knock LED" mod. It cannot be used to tune. You'll find install instrctions under "Electrical" here: http://www.vfaq.com/FAQlocator-index.html
Read this before you decide to install it: http://www.dsm.org/archives/1999/07/19990716.txt/32.html
It's only a severe engine damage warning indicator.

You can crank the PSI as much as you want, there is just a direct coralation between how much boost you put in you car and how much $ your going to put in your car to fix it. ,... but seriously it true

BTW, 93 octane dies out at around 20 psi. I wouldn't go 18psi w/ stock injectors unless fuel press. was raised. Oh yea, a logger is nice

KNOWBODY knows whats safe and whats not. The only way you will know what is safe for your car is to get a logger. You can pick one up on ebay for less than $200.00. If its now or later you will need one in order to tune properly.
