You want a cheap mod? Take a 1/4" drill bit and drill your fuel injectors out. Puts the fuel right to the motor. Haulin azz after that.

But seriously, get a programmer if you want performance. But if you want gas mileage, I use Lucas fuel additive to clean out my system. And I've done a seafoam treatment. Cleans the upper and lower parts of the engine. Pretty spiffy. But in all honestly bro, it's a jeep, gas mileage is gonna be a problem, day or night, rain or shine

Oh and depending on how many miles, change out the fuel filter, you'd be surprised how much that actually helps out.

But an example of long intake runner length was on the C4 Corvette Tuned Port Injection system (TPI of the mid 1980's) which had a total intake length of 17 inches and produced incredible torque at a low RPM. In fact, there was a modified system to gain more upper rpm power by shortening up the overly long intake runners. I'm pretty sure intake runner length is directly related to intake velocity at a given RPM range - longer length for low rpm and shorter length for high rpm.. The TPI long intake runners were great for low end, but sucked for upper rpm gains in power..


The intake manifold length makes a difference. The closing of the intake valve makes a pulse in the airflow ( think when you close a door in your car... It can make a puff of air out of a cracked window. That's why they tell you not to close your door hard when you have a new windshield put in because it can damage the fresh glue) that pulse bounces off the throttle body, and back into the engine, resulting in a slight forced induction effect. This only works at a certain RPM range, depending on the length of your intake manifold. Some cars have a variable length intake manifold, that changes the length according to the RPM's. Google VLIM or Variable Length Intake Manifold. BMW came out with an infinitely variable type. They stopped doing it because the gains in HP weren't enough to offset the cost. Most are two stage, meaning they have 2 lengths to choose from.

But if there's a certain RPM range you want extra power in, keeping in mind that there won't be a huge difference, you can build an intake to do so.

This throttle body spacer might do it, if I understand the physics right. Otherwise, it would be only good if your fuel mixes with your gas before the cylinders, I. E. TBI or carb.

If I'm wrong please correct me but that's the way I understand it.

Does anyone know how many hp you gain from removing and bypassing the ac compressor? How about going to an electric fan?

Not enough to make it worthwhile. Well, the AC compressor probably uses a fair bit (with it running) but with it OFF, its probably about 5HP at the crank, and an electric fan may net you about 10HP at the crank.

I actually havent done either of these, but Im going by the averages seen by other vehicles.

It's on my list of things to do. The ac hasn't worked on my jeep since I got it and I'm not going to fix it so I have nothing to lose.

That's good enough for me.

When I had a Geo Metro I had to turn off the ac on the highway when I was accelerating to speed or pulling a long hill... Otherwise I couldn't keep up.

check the seams, the stitching tends to pull apart overtime. I have found the best fix for it is to take a small amount of clear silicone and run it along the stitches. If its done right you wont even notice it and it keeps the water out very well.

I never thought a thread from 06' would 1. survive this long and 2. turn into talking about leaking tops 6 year later!
