My Proof

I made a video to prove that I get well above 32MPG, I don't know how all the science or the technical questions as to how is this possible. I've just been doing the same strategy that I've sticked to with all my cars that I have had, which is to try to provide less drag on the engine in all its aspects.

Now before you watch my video, you need to know the tool that I use to calculate my MPG, which is pretty much done for me and is an awesome application that can calculate all kinds of info like horsepower aswell. PLEASE WATCH THE FIRST VIDEO BEFORE WATCHING MINE TO ATLEAST HAVE AN UNDERSTANDING OF THE TORQUE APPLICATION, you don't have to watch it all, but just enough to have a concept of what it is and what it can do, because I don't have the time or effort to explain it in my video.



NOW HERE IS MY VIDEO, I got a nice suprise at the end of this run. I guess the result was a lot more than the previous run I did before, before I replaced my driveshaft for a lighter aluminum one. I stopped wanting to know my MPG after I already knew it was well above average, I just knew it would only get better the more I improve in the rotational weight reduction project.

Oh yeah, you get to see me in this video, so it happens that I am latino, so I hope you guys don't turn out to be racist too. Seeing how Im now frowned apon on these forums recently, either do to some of my ignorance in creative thinking, or perhaps its created by the jealousy of others seeing how I am even capable of producing anything higher than the normal, yes I'm aware that a mustang with this much MPG may seem impossible. Anyways, enjoy.

Well that was very informative,thanks for sharing. It seems that all your calculations seem to be right. Was the aluminum drive shaft hard to install? I mean If someone can change the brake pads...would this be as easy as that?

Also, do you really think an aluminum drive shaft is worth getting?

My car is an automatic,I don't know If that matters or not.

But yeah, thanks to any info you can provide to me.

A driveshaft is just bolted to the rear axle by four small bolts and the front end of the driveshaft simply slips out of the transmission, fairly simple.

If an aluminum driveshaft is all you'd have, then it would be very minimal the effects of any efficiency. The bigger mods to effect efficiency are the underdrives and the K&N Filter, and Iridium plugs. Basicly its all the mods in my sig working together that have helped in my mileage.

Having an automatic transmission is ok, but compared to a manual/standard transmission, its kind of a downgrade. You do get more benefits in mileage and endurance with a manual stick shift.

Not trying to start a bicker, but only going 15 miles of consistent speed says nothing about your gas milage. I have been apart of groups that did FTP tests and it is way different than what you are testing, you are testing best possible MPG in the best conditions. The EPA does all the testing in worst case senaro. I have attached a picture of the FTP(fed. test procedure), its nothing like what you have done. hence why you get better fuel economy than most. Yes I understand that you get better gas milage than everyone else. Yes we all could get better MPG if we drove better

City which is what you Claim

It wasnt consistent, it was simple stop and go traffic, granted it wasnt bumper to bumper traffic.

So you want me to test my car in like a FEAR FACTOR CHALLENGE kinda of way? Who in reality drives this way?

So the EPA numbers they provide for their vehicles are worst case senerio numbers, yet people who drive their cars around un-worst case senerio still get the same MPG that EPA states.

You saying I drive like a granny??? lol

Fill tank. reset trip odometer. drive. once out of fuel divide miles my tank size (gallons). there's your MPG. or at least close to it.

You guys will never be satisfied, nothing will ever be good enough for you all. Even if I raised the bar on the torture my car has to endure, you will still say it isnt enough. Just because it doesnt make sense that my car isnt as dull as yours.

Well I'm not going to be your internet monkey to run car tests on. How about you put your car through that torture you want me to prove to you, LETS SEE WHAT YOU CAN DO. You either accept that I am getting well over good MPG, or you remain skeptical. I dont care. I just know that what I've been doing has given me results and it shows. You dont want to accept it, it aint my problem.

Look Im not disputing on your gas milage. I do understand that you got 39.5 MPG . I will say it again. You got 39.5 MPG, good for you. But comparing it to the what the EPA says your car gets (27 MPG) it not the right way, you shouldn't say that you are getting so much better gas milage than us because of you mods and crap like that.

This is what Im am trying to say, I accept that you GOT 39.5 MPG when you tested. But I am skeptical on how you tested. savvy

To be clearly honest:

K&N CAI Filter, No Thermostat, Underdrive Pulleys, Aluminum Driveshaft, NGK Iridium sparkplugs, RAMstyle forced air scoop, Flowmaster 40 muffler


Going by this mod list, this car would never get to proper operating temp and would get worst gas mileage than most.

I'm with the above. Fill the gas tank, set trip, ride til the its damn near empty. And verify this by how much gas you get the next time... And do the simple math to tell the MPG. I'll remain skeptical of double the normal mpg for that car with those mods no problem.

Pelle- Didn't think I'd see anyone else familiar with the FTP cycle here. :eek:

But I have to be very, very skeptical of this one. First, you're using a notoriously inefficient engine (sorry 3.8 guys, truth hurts), you have little no no modifications stated that would drastically improve milage, and if anything the lack of a thermostat would destroy fuel economy due to the extended time to get up to temp.

I mean I can understand that if you cruise at just the right fuel consumption point for a brief period and use that for your average it can yield an unrealistically high number that you give.

But to me, the red flag is your measurement. You said your car has no odometer or trip counter? Come on man. Then your calculations can't be considered remotely accurate. I wouldn't trust an "app" as far as I can throw it. Public broadcast fuel economy is notoriously inaccurate. In fact the Ram guys joke about it and call it the "lie-o-meter" all the time. Not even the industry uses that as a gauge of fuel economy.

There is a guy in the 2.3 section who did some impressive ecomodding to get into the 40's though. But he did things like extensive weight reduction, air dams, lighter tires etc... to stretch the most out of it.

Not to bust your balls or anything, but I'm skeptical of your data.

The whole trip was preplaned. The route I used was exactly 15 mile distance???? I showed this in the video then gave a link to the route I used in a post on this very thread, what more do you want??

The app used only OBDII information from the same source the trip counter would get its. Come on.

I only slightly skimmed what everyone said but I can understand how you got 38-39 mpg going an average of 22.5 mph if it took you 40 mins to get 15 miles. But in reality city driving is probably faster than an average of 22.5 mph. Guess it depends where u live etc. Regardless though if your average drive everyday is only 22-23 mph then more power to ya but it might just be me who likes to get on the pedal a little bit more.
 
#31 ·
if I was going 20mph, it wouldnt make sense or add up, meaning that it wouldnt leave any room for any stops at all for a 40min drive. Meaning that even the first stop I showed in the video wouldnt have even existed, or even the moments in the very beginning of me still at the gas station starting the car when I left my car running idle for a good while buirning gas.

I showed you a map of the route, it had around fifteen stops, granted maybe i got lucky on a few with green lights, but saying that I did the whole trip doing 20???? seriously, you understand why this cant make sense. The video clearly shows atleast a decent speed above 40mph. Perhaps maybe, just maybe, at least half of those 40 mins were spent at boring stops I neglected to show in the vid, for the sake of simplicity and annoying repetition for a video of just meaningless driving.

again....seriously

for my entertainment I would love to hear how all you mods work together in order to get you said MPG.

As Reaper said, I have nothing against you but a lot of the stuff you are saying is just down right stupid. manufactures put **** in cars for reasons. they have millions of dollars in R&D to make vehicles as efficient and reduce emissions as much as possible. If all they had to do on new cars was your mods they would for their CAFE. even if they only could sell them in the southern states. My program sends a lot of people out into the automotive field to work with the EPA requirements. I have taken Classes dedicated to efficient vehicles and so on, You are right in some cases but the over all point is wrong. you can do make a inefficient vehicle efficient just by wrong testing. YOU NEED A SOLID TESTING PROCEDURE. They only way that your procedure is tested with accuracy is if you drive till the tank is nearly empty.

Two words:

Money (always focusing on less cost to the company, but still produce a fuctional product)

Warranty (A product that will last atleast a good lifespan, therefore using less efficient parts that will safegaurd for a failure or more dependable to last longer, but sacrificing any efficiency benefits.)

(Also having more efficient parts cost more, which goes back to cost/money issues, an inconvenience to a company when all they need to produce is a fuctioning product that many can be content with.) MONEY AGAIN

Seriously you must be slow to think that a 15mile test is accurate for mpg at all. This has just gotten to me since its still going on. Who cares? Data is not supportive. Perform realistic tests or GTFO. No one drives 22 mph for only 15 miles and takes that as their REAL mpg. Who cares>?

And maybe not as much in the sixxer section, but really, not many people buy a mustang for its gas mileage. I mean, really. I'm a realist, this is reality, and these aren't Prius's.
 
#51 ·
Oh and yes by all means, do the mods I have listed. Thats why they're there, I have nothing to hide. And like I said, Efficiency is Performance, most of these mods are well known performance mods, so what if they happen to make you car faster and more efficient. More power to ya, no need to start a debate about how something that is suppost to make your car faster also helps you conserve engine energy if you would just run it normaly.
