Topic: Save Money At The Pump!

[bluedevil]

The price of fuel is a topic on the minds of all Americans. War, weather and politics have the price of regular, unleaded gasoline teetering just above the $3.00/gallon mark with no sign of relief in sight.
As truck enthusiasts, convincing any of us to run out and buy some compact, fuel-efficient hybrid is just unrealistic. But, there are some things you can do to fight back at the pump (and gain a few extra horsepower on the way). Interested? We thought so. This article is designed to show you some of the things you can do to squeeze a few more miles out of every gallon by maximizing the performance of the three main areas that contribute to your vehicle’s efficient use of fuel: air intake, exhaust and fuel/spark delivery.

Air Intake System
Your engine needs to breathe, and the more air it has available the easier it is to generate power. But, at the same time, you need to filter the air going into your engine to make sure dirt, dust and other particles don’t gum up and damage your engine. Factory air intake systems use paper filters, and while they do clean the air very effectively – they are also very restrictive to air flow.

High-flow intake systems and replacement filters, on the other hand, provide excellent filtration without restricting air flow. Companies like K&N use oiled, cotton-gauze filters that trap tiny particles and flow almost as much air as running no filter at all! Couple this high-flow filter with the free-flowing intake tube (found on K&N’s FIPK kits) and we’re talking about a serious increase in efficiency. Efficiency you’ll appreciate when you step on the gas and when you fill up your tank – (see figure 1).

Exhaust System
Vehicle manufacturers must comply with government regulations and design their exhaust systems to meet the needs of the average driver. Production cost, noise levels and other factors often force automakers to tune down the factory exhaust – which has a negative impact on performance and fuel economy.

Performance exhaust manufacturers, like Corsa, Gibson and MagnaFlow design their systems with power and mileage in mind (the great sound is a bonus). These systems use mandrel-bent tubing and high-flow mufflers to allow exhaust gases to escape more efficiently and free up your engine to produce more wheel-driving power. The result, increased efficiency and improved mileage – (see figure 3).

Fuel & Spark Delivery
The final component of the performance equation is fuel and spark delivery. On most modern vehicles, this process is controlled by your vehicle’s computer system. As with exhaust systems, your vehicle’s computer system is tuned with the average driver in mind.

Programmers from Hypertech, like the Power Programmer III or Hyperpac, allow you to optimize your vehicle’s computer to suit your specific driving style. In addition to advancing your vehicle’s power settings, the Hypertech programmer also allows you to tune the computer to work more effectively with additional performance accessories like intake kits and exhaust systems. Finally, Hypertech’s exclusive Dual-Fuel® tuning increases power whether you choose to run premium fuel or regular – (see figure 4).

Another easy (and inexpensive) way to pick up a few extra miles is by adding a set of performance spark plugs. E3 performance spark plugs burn stronger than standard plugs – creating higher temperatures and more complete combustion. The result is up to 13% better fuel economy, up to 12% more horsepower and reduced emissions (up to 58% over the life of the plug).

Well there you have it. We hope you learned a little something that can help save you some money at the pump.



1. High-performance intake systems and replacement filters flow more air for increased mileage and power.


2. Performance exhaust systems boost efficiency for better mileage.


3. Hypertech's Dual Fuel tuning allows a vehicle owner to go from premium fuel to regular with virtually the same power.


4. E3 spark plugs improve fuel economy up to 13% over standard replacement plugs.

Well, I've got at least one of the four items on the Av already!! Now, it's time to attempt to convince the boss to let me do some more modding!!  Wish me luck after these week's "wheel war"!! 

[MoAv]

You should win this one to B94 - just go on about the increased fuel mileage.  If she's been with you when you filled up the tank, it probably won't even start an argument!!

I now have all 4 (sorta).  Just put a K&N replacement filter in, already redid the exhaust (although not the catback), and have the high performance plugs/wires going in hopefully next week. 

We'll see what the whole package does for my mileage

A supercharger will increase the efficiency of an engine as long as you keep your foot out of it.

Has it increased YOUR gas mileage?????        

[bluedevil]

lol....i get 12.

maybe cuz i have  an 02 sensor bank 1 check engine light on since i installed the blower.

I didn't see any benefit after installing E3 spark plugs, and removed them after getting some misfires.

[Fowlhunter]

What about the efans, wouldn't they also help with gas mileage??  Less lag on the front of the motor means putting less foot into it???  Well it sounds good!!  Still working to purchase mine!!!

It's supposed to be 1-2 mpg more but I didn't see it.

The Flowmasters didn't help my mileage any... again, due more to a heavy foot prodded on by that rumble

I didn't see it either from the efans.

I never used them either.  I used Iridium plugs by Denso. $13ea

I can't recall but i think i use either NGK Iridium IX or SplitFire Triple Platinum    lol...i dont remember

I was wondering if anyone has used a Hyper tech programmer or Fitch fuel catalyst running E85 fuel and what the MPG increase was? I am trying to install the one that will make the best improvement first then maybe the other later. Right now I am getting around 13.4 MPG using E85 in my 05 FFV avalanche. I have already installed a K&N air intake and would like to go further using less fuel.
Would appreciate your input on this, Ken.

Spark plugs next. I dont know much about e85 as my truck isnt compatible.   Before you try the Fitch Fuel Catalyst,ask the vendor if its compatible to e85 engines. I looked at their FAQ's and no e85 info was available.

I hope someone else chip-in more info about the handheld programmers for ya
