I may be wrong by saying this because I don't know much about supercharger's, but wouldn't some kind of methanol injection help out? If I'm wrong about this one just let me know

 

it would bt i think they say it adds like 11hp or something correct me if im wrong someone. Just doesnt seem worth it to me

 

Ohhh ok then well thanks for the info so I don't make myself seem stupid by bringing it up again down the road lol........ I think that the NOS would be a good idea, so then you can use it when you need it instead of you supercharger running at higher boost everytime, because in dew time the supercharger wears down your motor.

 

With the centrifugal SC you're really only going to use the higher boost when you need it... I very rarely get to 5PSI on the street... Going WOT and getting the RPMS up to 5800 on the street is a bit much! LOL! But on the track where I need it I get 10PSI... N2O (not NOS) really complicates things and introduces addtional points of failures... N20 solenoid sticks open, fuel jet clogs, fuel soloenoid does open... I would avoid N20 on a blown stock 4.0L motor unless you can afford to repair/replace your motor and not have your car for a couple of weeks...

 

While methanol might not give you big HP gains it does raise your octane level to some where around 106... which is just another nice layer of safety!
