I am trying to figure out what engine mods i can do to get maximum hp/tq gains. I have already added flowmasters, AEM bruteforce CAI, and a superchips flashpaq tuner. I am still thirsty for more power though, I plan on putting HFC's and a 3" pipe from the headers back on soon, along with new headers. what else can i do to give me more power? Thanks guys

 

You could get underdrive pulleys

 

What kind of gains and prices am i looking at with those?

 

Supercharger.

 

Not much gain, there isn't a whole lot of power adders out there for these engines

Over $400 for the 5 piece combo.

 

Thats disappointing to hear. I know supercharging it would give you a pretty good hp gain. but it also will kill my gas mileage. worth a shot though

 

what about boring it out? worth it? or not?

 

nope. The best engine mod is a 5.0 swap

 

...grandmas got a 5.0 mustang, 44k on the engine. hmmm haha
