Anybody have any luck with various throttle body spacers, prefer one over another?

 

they do not work on are trucks, because we have a TB.. all they do is look good. if you think i'm not right use the search button and you find alot of info on tb spacers

 

nothing but bad bad bad, made my truck run like crap and ate more gas, so i took it off, they work as a good paper weight

 

I'm surprised to hear that. I added a TB spacer and my gas milage improved to over 30 mpg and I am now getting over 400 hp out of my 318, not to mention my truck handles much better on tight turns.


j/k

 

uhh, that's not entirely correct.

Throttle body spacers don't work because we use an open intake manifold design that uses Manifold Absolute Pressure (MAP) as opposed to Mass Air Flow (MAF) air metering to determine fuel trims.

The air coming through the TB and the spacer hits a big open space in our manifolds (the plenum or "Keg" area) and any increased velocity, twisting, spiraling, rifling, or whatever else the TB spacer manufacturer claims the spacer does gets nullified when it hits that large open space. Then the air stops and waits for the intake valve to open and load the combustion chamber with a charge of air and fuel.

 

I've always heard they are junk and don't work. Save your money for something else

 

+1 learned my mistake , hopefully people take my advise and listen

 

WOw you only get 30mpg? I get at least 45mpg with a 5.9L engine...shame! lol

JK also...tb spacers ftl! get a fastman tb for gosh sakes!

 

I've never seen it explained in depth like that, thanks squirrels!

 

dodgeram07 is correct in that the TB only allows a metered amount of air thru and unless you're at wot, those "twister" ribs they put in won't even come into play, but it's the bottom end of the intake that really undoes all the "work" they do.
