How to install AFC & Opinions on upping boost 10 psi - Toyota Nation Forum : Toyota Car and Truck Forums

numbone · 09-10-2005, 08:07 AM

anyone have detailed instructions on installing afc II ? i also got a manual turbo xs boost controller lying around. do u guys think it safe to install it and up the boost to 10 psi with stock intake and intercooler. i have 5zigen dual tip exhaust w/ 2.75" piping.

Factory boost maxes at 11.8 psi, so running 10 psi would require you to turn boost down.

i'm running 0.6 bar. consistantly thats about 7 psi correct? why do u think it is? shitty gas?

Do you have an aftermarket BOV? this may be the cause.

Are you sure you aare measruing BAR?
1 BAR = 14.5 psi
So if you are running .6 you are hitting 8.7 psi.

I would first question basic maintenance items:
Cap, rotor, wires & plugs?
Fuel & air filters?
What kind of fuel are you using?

i have the greddy type S on it. Going back to OEm though. but the car boosts 0.6 just like it did with the oem. as for gas they dont give specific octane ratings but i hear its like a shitty 88 but others 95 not really sure. as for ignition what shud i look for in terms of seeing if things need changing. i'll have my timing checked aswell.

You should have a fresh Toyota ignition ~ cap, rotor and wires and some good cooper plugs (or at least some factory platinums).

What year is painted on your ignition wires?
If it is anything older than 2003 I would be concerned.

If you are using 88 octane fuel, you are never going ot be running at your full potential.

Whoah hold the phone. One bar =14.7 psi. This won't make so much of a difference on low boost, but if someone were to run say 30 psi, you saying that one bar =14.5 psi would be way off.

How long should I hold the phone?

One atm = 14.7 psi (atmosphere)
One bar = 14.5 psi
One hg/cm² = 14.22 psi (what a lot of boost controllers/gauges read)
