Question about 1994 Jeep Wrangler
I am currently looking at replacing my air intake and exhaust system. Is there any avice on what headers and what diameter piping to use also what should i be aware of about back pressure i don't whant to burn a valve. currently I am running 33X12.50/15 tires and it has enough power but i would like a little more up in the mountains. I have installed a throttle spacer and recieved a little more power out of it but i need more.
You are correct in replacing both intake & exhaust (you can't put in what you can't get out. "headers" are rpm sensitive, as they scavenge
by using both a moving "slug" of exhaust as well as resonant frequencies. Many manufacturers offer "matched sets" (intake & exhaust for this reason. On a "utility vehicle" such as a Jeep, you must always keep rpm range in mind, using items designed for "mid range" of 1500-2500rpms as a base.The easiest way to get more hp is by doing intake, exhaust and a mild "rv" type camshaft. More expensive is to use a turbocharger (but has limited value at lower rpms) Superchargers offer "off the line power" but are very expensive, unreliable and difficult to get "tuned" properly. An aftermarket "tunable" ignition system is also another option I'd look into. It's another way of changing the engines power curve.Or, how about just changing final drive gear ratios? Don't forget though that most power gains also equal less mpg's.
