Okay guys I have a 2004 Jeep Grand Cherokee Overland 4.7 V8 H.O

Want to try to add as much horsepower as I can without messing with motor.( like taking it apart and messing with the block)

Currently I have
AirRaid Throttle Body Spacer
aFe Stage 2 Cold Air Intake
Borla Cat-Back Exhaust.

Wanted to get headers, but non are sold for the 4.7 H.O

Any suggestions to add even more horsepower without spending thousands of dollars?

 

nitrous, supercharger would be a nice one.

 

A supercharger is like 3 grand :/

 

Yep, and that is how much u r gonna have to spend to get any major improvements, other then nitrous. Todays engines are tuned pretty good from the factory, not much u can do to them.

 

Any place to actually get a supercharger for the 4.7 v8 cause I can't find one..
