ford uses red anti-freeze, of course they're wrong

how do these spacers benefit carb'd or TBI engines? does that extra inch or so of space allow the fuel to mix w/ the air better before it enters the cylinders? i can see how more evenly dispersed fuel being beneficial to power/milage.

the only possible way i can think of a spacer working on a MPI is it increases the volume of air under the TB, so when the valve opens, that little bit of extra air can make up for the TB not being fully open right away...but then that would only work in the split second it takes to open the flap all the way. and even then i don't believe that would make a real difference.

and naekid...how were you getting 17mpg, especially in the thin cold air of canadia? driving downhill w/ those blizzard winds against your back?

I dunno .. that's what my numbers show ..

On to my report for May 18, 2008.


I was doing some welding on my Jeep - so I disconnected my battery and lost my trip-meter settings (just built a new rear bumper / trailer-hitch). I lost out on reporting on one tank of gas .. but, I should be good with this report.

I was heading out of town on the long-weekend, filled up before I ran out.

KM driven: 315 (miles: 195.7)
Litres taken: 43.7 (11.54 US Gallons)

It gave me 20.36 miles per CadGallons
- or -
16.96 miles per US Gallons
- or -
13.87 litres / 100km.

It dropped significantly from the previous tanks. I checked my air-filter and it looks clean still. I will see if there is something going on that not right, but, I will say that we have had weird weather during that time - very high winds that I had to fight against that might have dropped my milage down. I will have another empty tank (possibly tomorrow) to fill up and will report again on what I get.

If anyone wants to see a copy of my receipts from the gas-stations or a copy of my Excel-file - let me know. I realize this isn't a "scientific" report - but, it will give an idea of what I am getting as an average MPG for an average guy driving an average Jeep in an average city with average weather.

Just the numbers again:

458km driven
58.9 litres for fill-up

21.96 Miles / CadGallon
18.29 Miles / US Gallon
12.86 Litres / 100 KM

[NaeKid]

The next round of reporting:

434KM (269.67miles)
58.141 litres (15.36 us gallons or 12.79 CadGallons)

21.08 Miles / CadGallon
17.56 Mils / USGallon
13.4 liters / 100km

I have installed 1 1/4" Alum wheel spacers on my stock rims/tires giving myself a slightly wider stance. My side-walls stick out just barely past my fender-flares. It does not look like the wheel-spacers have impacted my milage in anyway (based on first tank).

I agree with Jerry. In forum after forum, there are hundreds of postings of getting more power, getting better milege, from a Wrangler. The end result is always the same, snake oil. From air filter setups to spacers, the same result. Also, three row radiators must be better than one row. Nope. Guys complain about the OEM radiator because it leaks after twisting the body off road and thousands of miles. But the OEM setup is the best. Sorry, I got carried away but put your money to better use, don't try and improve the engine.

[NaeKid]

I have two updates:

I filled up on Jun 7 with a total of 57.4L of gas for 457 km driven.

22.49 miles / CadGallon
18.73 miles / US Gallon
12.56 L / 100km

That same day I installed my 2" RubiconExpress lift. I am still running on the stock tires / rims - no change there. I just filled up again today.

58.67L of gas taken in for a total 420 km driven.

20.22 miles / CadGallon
16.84 miles / US Gallon
13.97 L / 100km

Looking back through the chart I had the same "bad milage" as what I got on this tank. Lets see what the future brings.

hey "xlr8n" what would you do for performance on a 4.0?i have a 2.5 theres nothing to do but re-gear for me to get power haha but anyway im tryin to talk a buddy into getting a quiet flowmaster 50series maby&aftermarket drop in airfilter(not k&n herd 2much bad ab them latley)what do you think?

[George Dickel]

I wonder why this thread died 1 1/2 years ago???

jefro-read, search, and be wise. If you want more power from a 4.0L, Stroke it or you could swap cams. Word to the wise, I did all that stuff in my sig line because I HAD to pull the engine and rebuild it anyway. Is it impressive? Yes. Will it hang with my almost stock Mustang GT? Not even close!

aaahhhh......another stupid throttle body spacer thread. it pretty entertaining though, especially when the op is excited about his work, then realizes that its equivalent to sh1ting on the top of the motor.

Yeah......It is really sad to see. Someone does a mod to his Jeep and goes to all the trouble to try and do some test and show how the MOD worked on HIS jeep and all he gets for his trouble is beat-up. If you are not interested in the topic and think you allready know it all, then don't read the thread.

First off, i don't think i know it all. But i do know, that TBS IS A COMPLETE WASTE OF TIME AND MONEY!!! With all the other threads that have covered this issue, getting beat up over it is to be expected.

I commend the guy for his work, but trying to prove something that doesn't work in the first place is like beating a dead horse.

Really?

Then don't read those thread if they have no interested to you.

What are you, the thread police? Coming to help the poor and the defenseless from the angry anti-spacer mob?

Guy comes here with pretty pictures and step by step instructions and Excel spreadsheets showing his gas mileage. Great! Except his "proof" doesn't prove anything. There are a million variables for gas mileage. Does he drive the same exact route at the same exact speed in the same exact traffic conditions every day? Is the air pressure and ambient temperature the same every single day? Is he getting his gas from the same gas station that uses the exact same fuel every time? Is his vehicle weight exactly the same every time? No, no, no, no, and no, no, no.

People are trying to explain to him, to give him clear technical explanations why the TBS won't do squat, and that his methodology is way off, and you claim he's getting "beat up"?

I repeat again what I said before: If TBS worked and increased gas mileage and horsepower, EVERY SINGLE JEEP WOULD COME WITH A TBS FROM THE FACTORY.

What are you "The thread bully" trying to intimidate everyone into believing as you do? Well.....It isn't working BUB! What brought you into this anyway ****head? You just been surfing, looking for a fight?

Lets see your test that shows that he is wrong. Oh.........I see.......You are just going on "hear say" and have really done NO test of your own .

How the **** do you know?

Now that’s about the DUMBEST thing I have every heard. I guess if Jeep found that a Super Charger would give better performance "EVERY SINGLE JEEP WOULD COME WITH A SUPER CHARGER FROM THE FACTORY" Gee makes sense to me.

I'm not trying to say that a TBS is or is not a good thing. I don't know. But there is a big difference between telling what has already been learned and a total "DOG PILE" and to beat a guy up because he is trying show what he is doing isn't a good thing for anyone or for that matter the "FORUM". If it doesn't work he will soon learn without being told he is a stupid **** for even trying.

LOL....more "in 15 minutes I'mma gonna bolt me on some horsepower" nonsense.
