Small VS Large Trucks

Dual exhausts?

 

[SkwerI]

Yup. My mechanic told me that he sees guys with the Ford v8's getting a consistent 3 mpg increase with dual exhaust. The motor has to breathe, better power, more efficient, so you don't need to mash the go-go pedal as hard. True duals from the cats back, not the fake 'stick a T on the pipe and run two pipes out the back' job. A reputable shop gave me a quote of $350 to do my truck. I may go for it next month along with the Airraid intake.

 

[MasterBlaster]

Thanks for the advice! Does anyone else concur? It makes sense to me.

 

[top hopper]

I concur about dual exhaust and the tune up.

 

[lumberjack]

It makes sense, but don't spend more money than you can recoupe in savings.

 

[MasterBlaster]

Trust me, I keep it tuned up and serviced.

Usually a simple cold air intake kit like Brian said is good for a few MPG, and a little more ponies as well...

Here are a couple:

Air Raid

K & N Filters

The free'er flowing you get that air in and out is the key. One of these days the exhaust on the chip truck is getting cut off, and an intake, I just can't bring myself to do it yet. The noise is what I don''t look forward too, early 99 7.3 sounds like a baby screaming.

 

[MasterBlaster]

I know when I cut out the catalyic converter on my '82 Malibu it really opened it up!

 

[SkwerI]

I just bought the Airraid for my truck, $241 with shipping.

Most shops won't cut off the cats and I don't want to do that anyway. Typical systems are from the cats back.

 

[GASoline71]

Yeah... there are not many shops that I know of that will cut a cat off a vehicle.

But there are so many aftermarket "cat-back" systems out there it's crazy. A 3" cat-back exhaust sytem will really help out and wake up that little V-6 too!

keeping your tire pressure correct makes a huge difference. Also leaving your tailgate down actually decreases your fuel economy and wears out the tires faster.

Use the correct oil, service your engine properly, and do not forget to change the air filter.

 

[MasterBlaster]

Haha, that's funny.. I paid the Midas guy an extra $20 and he cut that sucker out tootsweet!

Yeah... there are not many shops that I know of that will cut a cat off a vehicle.

 

[lumberjack]

I made the switch to snythetic in my Civic. I should have an idea if an mpg boost alone justified it.

 

[GASoline71]

...Also leaving your tailgate down actually decreases your fuel economy and wears out the tires faster.

This is true...

I love seeing all the chuckleheads around here driving with their tailgates down...

Also, very good point on the air pressure in the tires Frans... Everybody has overlooked that at one time or another. Just easy to forget about them until their almost flat.

[Tom_Scheller]

Tire pressure and driving habits are huge.

As for chuckleheads... driving the Expedition at 85mph...

Wind resistance is exponentially related to speed so slowing down saves big time. Yes I'm the one in the right lane driving 60. You can beep and wave if you want. I'll wave back.

[Frans]

I think I read that the best fuel economy is at about 25 MPH

 

[MasterBlaster]

That would make for a slow commute, but it's better that horses!

first thing I did when I got my new truck was go to Lordco and get me a K&N filter and swap out the filthy paper filter.
I may go to better exhaust when I get some $$ hanging around with no better use. Likely a Flowmaster setup or something similiar.

 

[lumberjack]

The most effecient cruising speed varies from vehicle to vehicle. The range I heard was 30-40, but that's still slower than my average drive.

 

[Paul B]

mine seems happy about 90Kph. gentle on the throttle and about 1300 rpm

True duals from the cats back, not the fake 'stick a T on the pipe and run two pipes out the back' job......

I laugh with I see guys with a big fat exhaust tip (mostly on Hondas, Subarus etc.) and the actual exhaust system is only about 1.5 inches. My Dodge Cummins has a 4 inch exhaust from the turbo back. The turbo is from the 8.3 liter Cummins.

 

[stehansen]

I have a flowmaster and 3" exhaust on my pickup, It made a huge difference.

 

[Frans]

I put a Walker 21463 direct flow 3.5 inch exaust system on my old '86 f350.
Seemed to make a difference.


As much as I like the K'N air filters, ya gotta be carefull and wash the things when needed.

I have seen alot of them get gummed up faster than the paper elements. Must be the oil in them.

 

[stehansen]

Don't want to do like these guys.
