PSI Saftey

[2GStreeT]

Not sure if this should go in the N00b section but ill try here!! Now im told 15PSI is safe to run just with a MBC. Now all i have is a K&N Fliter, MBC. and a boost gauge. Im runnign 11 PSI as of now how much further can i go with the boost stock? or am i pushing it?

I was running 18psi with just exahust and your mods (well, I had EGT gauge as well)
Ofcourse I can't say 18psi is a 'safe limit', but many wisemen on this board tend to think so.

The only thing that I had to battle running that boost, was high EGTs when throttle is applied constantly

You should be able to crank it up anywhere from 14-16psi.

Ill run 15 PSI. So should i leave it at about 15 till i do fuel mods (550CC and a 255 Pump) or can i up a lil more with other mods!!!

1. UICP
2. BOV
3. INtake
4. Cat back this is my upcomming list

You can try slightly increasing it little by little until you hit fuel cut, but I would say don't go higher than 16 without a fuel pump.

Ok ill just go 15 for now. Now i need some input i hear if i get 550CC injectors and a 255 LPH pump i can run 18-19 PSI on stock side mount now if that is safe and true would i be better off doing that or getting an Catback 3"?

turbo-back 3"!
with 550cc's, you'll need fuel management. just get bigger uicp and licp, the stock smic is capable of high 12's (saw some car somewhere with the smic doing 12.6). i'm currently running 15psi, though i don't have the egt installed yet, just the wire and probe... i tihnk 17 is safe with the stock piping, 18 with bigger piping, and i'm guessing you can hit 20 with a fmic or some sort of ic spraying

Fuel Managment do you mean a Piggyback system?

if you want more complete control. but the apexi afc works fine, that's what most here use, i believe... check out the air/fuel control section in the parts catalog for other options
