Hey all,

Well, I have my Durango Supercharged! It is awesome! I still need to get it on a Dyno to have someone tweak it from that avenue, but as far as having it installed and programming the EFMU out of the box, I am good to go.

My question is how much psi the S/C will produce without any mods done to the engine? I have read that 4-6 psi is very common, while adding things (better throttle bodies, things for better compression <--I am going from memory here so forgive me) will allow more boost. Is this true? I am also saying this on the pretense that I am not shifting through the gears (1, 2, D) but letting the Automatic tranny do its work.

Anyway, replies will be much appreciated. pics on the completed engine will follow

Thanks all
-Eddie

I think 8-10psi is around what you should see from the stock kit. You could change pulleys to get more boost, but wouldnt recommend it on a stock motor. You could get away with it with a good tune, but you'd be pushing your luck.

Are you running a boost gauge or wideband AF gauge? If not, Id HIGHLY recommend investing. Without knowing what your AF ratio is, your motor could be a ticking time bomb.

Thanks for the help. I am running a boost guate, and it is reading the same as the EFMU, about 4, maybe 5 psi. I have an AF guage that I am trying to figure the wiring on, since the guys that did my exhaust removed (I think) my O2 sensor.

Is it a narrowband AF gauge or wideband?
