i was just looking at this site. http://www.fueleconomy.gov/feg/sbs.htm
i put a 1987 mustang (non mass air) vs 1989 (with) 2003 mustang 4v and a 2006 mustang. all v8 with 5 speed trans. they all have almost the same emissions and fuel cost? the 1989 compared to the 2006! check out the site and let me know what you think.

yeah its true, the v8's do not have to work very hard on the freeway to maintain speed. I get 25mpg on the freeway in mine going 75mph with 3.73 gears

No way. I have 260k+ on my car, all with 3.55's, and 250k of it was on a bone stock engine. The best mileage that I ever got was 22mpg. Recheck your math.

check it for me

280 miles, 10.89 gallons.

Roll your eyes all you want, but I call there is no way that a 5.0 gets 25 mpg with 3.73's period. I'll bet you any amount you are willing to lose that you are wrong.

did it 3 times, not once.

salina's, ca to ventura county

not a big deal

only thing that matters I suppose is I also have underdrive pulley's, electric fan, full exhaust (no cats), and my belt is 44.5" long (no p/s and no a/c).

wtf is the big deal? Stock they are rated to 24 highway, and the window stickers say 20-28 was observed.

3.73 gears makes no difference, if I'm not touching the gas pedal on the freeway I'm not touching the gas pedal, the rpm doesn't effect the gas milage.

Posted by BlueOvalRacing (Member # 1531) on :
 
28mpg observed? Not even downhill, with a friggin tailwind, in a 5 liter. 4.6 maybe, 5.0 never.

I've never taken a drive from Salinas south, but unless you can coast for 50 miles, your claim is bogus. Putting in less than 11 gallons means that you would be able to go another 50-60 miles (minimum) on that tank.

I could care less about your short belt, pullies or any other mods, your quote
"3.73 gears makes no difference, if I'm not touching the gas pedal on the freeway I'm not touching the gas pedal, the rpm doesn't effect the gas milage." is just plain wrong. Your RPM is higher in every gear, and no matter how lightly you push the go pedal, it still uses fuel more rapidly.

Check your speedo calibration. My guess is that you still have the speedo gear from your 2.73's, hence the high mileage reading per tank. More RPM's = faster speedo reading = more miles to a tank. Either that, or you aren't filling your tank completely each time.

And Sal, you better be yanking my chain, because the bet stands for you too. As much as you are willing to lose. 390??? You are supposed to stop taking narcotics as a police officer.

Hell, I'll follow both of you in my truck from any gas station to the location of your choice, and if you make it 280+ miles for Blind and 390+ miles(lol) for Sal, I will pay up on the bet on the spot. But, if you run out of gas, make sure that both of you have enough cash left over for the towing company after paying me off.

no need, here is what it would look like.



read closely in the bottom left hand corner, EPA observed 20 to 28mpg

You have no speedo. You also have no clue. The bet still stands. Put up or shut up.

Your car does not get 25 mpg with 3.73's

That's fine, but I just think he's fudging to the high side on mileage. If he said 21-22, I would be willing to drop it. 25 is too high. I have people on here that will vouch for my credibility also.
And just because you meet someone, doesn't mean that you should believe everything that he says.

$.02

25 is what I used to get in my 90 LX hatch on the freeway. I used to drive from San Jose to San Diego along I5 at 75 mph. 512 miles door to door. The car was completely stock minus flowmasters and electric fan + 3G alternator. But with 3.73s, thats one of those things I'd have to see to believe.

lmfao, I have no reason to lie!

next time I make the trip I'll take a picture of the receipts with the street addresses so you can google map it for the driving distances.

Posted by Blu50Stang (Member # 489) on :
 
25mpg is very possible. I got 24mpg in my blown 88 with 3.73s averaging 75mph up I5.

Posted by BlueOvalRacing (Member # 1531) on :
 
You know what blind, unless you can use your odometer, any map/gps/road signs etc. will not help your case. A correctly calibrated speedo/odo will prove my point.

And Blu50Stang, the bet stands for you also. As much as you are willing to lose. Your claim is almost as funny as Sal's.

Posted by silverLX (Member # 3207) on :
 
Blueoval, WTF is your problem? These guys are not lying. GPS is way more accurate than a stock speedo that has been corrected for use with 3.73's. What are you willing to bet these guys

Posted by BlueOvalRacing (Member # 1531) on :
 
No problem, I just own a 93 5 spd car that I bought brand new and put 3.55's in it when it had 1000 miles on the odometer. I put the right speedo gears in it, with less than .1 error in 5 miles. I have checked it numerous times.
I personally have put over 260,000 miles in the car, bone stock, (removed the silencer and put in a K&N filter) and the best mileage that I ever got was 23 mpg on the way down the hill from Reno. I got 19-21 mpg driving it like a grandma EVERY DAY for the last 11 years.
When someone makes a claim of 25 mpg all the time on 3.73's, I am skeptical to say the least.

Silverlx, a correctly calibrated speedo is more accurate than gps. My car can prove you wrong any day of the week. And the bet is for any amount. As of yet, no one has accepted the wager.

HungryHippo, when you can keep your ride on the asphalt, then you can spout off. Other than that, post whore somewhere else. And btw, blueoval is another guy on the board.

its not all the time that I claim 25mpg, I claimed it 3 repeatable times on the same exact trip.

here is my route, only this is from city center to city center:

http://maps.google.com/maps?q=salinas,+ca+to+camarillo,+ca&hl=en


yeah, my GPS is way the F' off, 275miles estimated from "salinas, ca to camarillo, ca" where I live, and filled up.


I dont know or care what it gets in everyday driving that is 50/50 highway and city. Hell it probably gets 12mpg and I'll let you think that if it makes you feel better

Man, I shouldn't even bother convincing you my explorer gets 22mpg on the same trip, that thing is spinning 2800rpm the whole way not 2500rpm like the mustang

You haven't taken the bet, so that's all I need. Congrats on your mileage.

Well, I can't prove you wrong, I just dont see why your taking the whole thing so serious. good luck with your wagers

Can you help explain to the rest of us why a GPS is innacurate (less accurate?) then an odometer for the purpose of mileage calculation of a known route? (such as gas station to gas station with a fill at the 'end' of the trip to determine vol. of gas consumed)

Are we talking about the 0.05% GPS error (or whatever it is), or what exactly? Don't want to put any words in your mouth.

I'm with the Ford Tech on this one. Best I've ever seen from ANY 5.0 I've owned was 24mpg, and that was in a bone stock 90 with the normal mods (no air silencer, off road X, etc). Folks can claim 28+ mpg...hope they feel better.

Thanks John! Finally, a little bit o' credibility from a well respected member of this board.

JoeT, I won't say that a GPS unit isn't accurate, (street signs, mapquest, yahoo maps aren't) but I will say that a correctly calibrated speedo/odo is every bit as accurate. Plus the odo will show any variances in the trip (stopping at Mc Donalds for a shake, etc.) that the GPS doesn't show. It all adds up. I'm sure that blind made no stops, so his mileage is accuate. But, unless you or anyone else can prove to me that a 5.0 stang with 3.73 gears can produce the mileage that blind claims, my statement stands.

season'd 88, I DO believe that a 2.73 geared stang can get 27 if driven mellow. I honestly don't remember what my car got with those gears, but I am sure it was close.
 

---

Posted by JoeT (Member # 298) on :
 
Would you accept that the shortest distance between two points (in a 3 dimensional system) is a straight line?

If you accept this, you must agree that any variance from said straight line would necessarily penalize mileage calculated assuming the path taken was a straight line. (your mcdonalds /bathroom, wrong turns, etc)

In that case, it would only service to lessen the mileage calculated using the straight line assumption. It could not possibly improve it.

Unless you suggest that a circuitous (sp) path somehow improves upon the 'shortest distance between 2 points is a straight line'.

You can choose to believe me or not doesn't make a single difference to me.

I guess I just keep the maintance on my cars up to date.

New things through out good air pressure etc.

I have no reason to lie to any of you.

If you choose to say I only get 10 mpg or whatever that's fine with me. I spend 30 bucks a week on gas and drive nearly 350-400 miles. I'm happy.

Posted by BlueOvalRacing (Member # 1531) on :
 
Joe, you are correct, but my point is that a 5.0 with 3.73 gears getting 25 mpg seems bogus. I really don't care about anything other than that simple statement. PROVE ME WRONG.

Sal, 390 miles on 2.73's would have to be in absolutely perfect conditions. 3.08's aren't much more, but the mileage should be less.

The bet stands.
