What do these actually do? Do these have proven gains in performance? Easy to install?

 

they do nothing

 

They make a cool sound, and improve your gas mileage.

you are misinformed

Throttle body spacers increase the volume of the intake manifold, which is one of the 3 differences between an H22 manifold and a civic VX manifold, along with runner length and diameter.

Adding volume increases the amount of "slirps" of air your engine can take without creating enough vacuum to pull more air through the filter and throttle body. If there is more volume, and you take out one strokeworth of air, you are reducing the amount of air in the plenum by a smaller %, and reducing the vacuum by a smaller amount, thus taking less force.

Throttle body spacers are great for cars with increased displacement, but they cannot hurt anything on a stock engine. Honda is very good at matching things like intake manifold volume to each engine, but after 100,000 miles if you take the volume from 2 times what you have to 1/2 of what you have, then plot it against the power you make, it is doubtful that the stock manifold will be exactly where your exact engine gets the most power.

So Eddiebx, where does your knowledge come from? Would longer runners on a $300 skunk2 inake manifold do nothing too? If so than we're all wasting money hunting down type-R manifolds and such.

Please back yourself up from now on, with something other than a post count. If you made &gt;1000 posts like this one you probably cost the Honda-tech community a month of wasted time, and hundreds of potential horses.

I want to thank you for your ignorance.

dude, i have no idea how you get that but, they don't do a crap period.

I am not about to type another page to set the stage for flaming.

proof me wrong by posting a dyno, please.

if you can increase gain performance by adding a piece of low tech hardware t o the throttle body, why the hell on earth will honda design the manifold the way it is?

spacer works wonder in carb'ed v8, gain is very very little if any you can feel in 4 banger honda motor

 

Without getting into a testestarone driven Pi..ing contest, I have to agree with the explanations put forward by EGmikeH22 and temper them with some obsevations between iam7head and Crono139. Because in the real world of Mo' is better, everyone is correct.
The designing of a powerplant is a compromise at best, between power, drivability, durability and economy. Everything works in conjunction with everything else, and conversly effects everything if not done properly. And it all comes down to where in the rpm range you want to produce power. Shorter Intake Runners (and conversely shorter Header Primary tube length) will induce power increases in the upper rpm range (at the expense of low-end power (torque) thru a phenomenon called pulse reversion. It can improve exhaust scavaging and improve the intake charge thru no more than the fancy understanding of the speed of sound, fluid dynamics and tube length selection.
All this is all well and good, and makes for great discussion at Honda R&D. But the short of it: Yes it can make "improvements" and have an effect, but only if you understand where, and make additional changes (in a balanced manner) like camshafts. ported and polished heads, swirl polished valves etc.
On a street machine with no other improvements it will be marginable at best.

it's called a dyno, you should try using one sometime, instead of infomercial racing.

so throttle body spacers now make your runners longer and can completely change the dynamics of a stock manifold? sorry, i must've missed that memo. if not, then wtf is your point? and waht does it have to do with a throttle body spacer?

and please show me how i brought my post count into this at all? thanks for informing me that i just wasted soo much of the internet's resources and killed everyones horespower dreams, as it seems internet = life to you
are we a bit insecure noob?

so according to your theory, we should run watermelon sized intake manifolds? thats plent of volume for you there. might as well get a hood scoop to clear an even bigger manifold huh? the more the merrier, especially if the car is old! cuz 2 times the x square root of the mean vaule will plot against the xyz axis and give you the magic number.

why don't you try and back up all your elegant formulas with some actual dyno numbers eh? since you sound so positive on your idea, proving it should be quite easy.

oh yeah thank's for the lesson on proper internet forum etiquette, apparently I am going at this all wrong and ruining everyones lives.

 

EGmikeH22 it's people like you that keep me coming back to HT thanks for the laugh


Throttle spacers don't do ****! end of story!

My point was stated: there are 3 things about an intake mani, and a throttle body lets you control one of them; volume.

No i said if you plot intake mani volume vs power output there would be some kind of a peak between double stock size and half, assuming Honda was close, and your engine is ~ stock configuration.

As far as massive intake manifolds, how about ITBs, they make your plenum the atmosphere, and people tend to gain quite the HP


The problem is that I am right, I didn't claim any kind of numbers, just a gain over stock by optimizing something you can control (intake mani volume) and all you said was that the spacers do nothing. The only thing we can all agree on is that they do something. If you put something on a car in the intake or exhaust track at all it is going to do something, weather its an inprovment like a header or a blockage like a tornado, it is going to have some kind of gain.

Now I can tell you that I don't really want to spend 100 on a spacer, then 100 on dyno time to run before and after I install it, so please don't go saying that anything I say has to be dyno'd but your claims of no gains don't.

I have used physics and real world examples to explain myself, you have not... at all.
not at all.
none, nothing.

So whatcha got

btw im glad this is bringing some people into the thread because it is a real good issue, and someone may actually go out and dyno a spacer if they have the facilities available.

 

I can see the case where a throttle body spacer could increase the volume of the intake manifold by some. Intake design does have major influence on the horsepower of the engine... Take for example the 2001 3.5L V6... vs the 2002 3.5 V6.... decent jump in HP and the only major change was intake design. Same withe the '02 3.0L vs. '03 and up 3.0L... up 40hp. That having been said, a throttle body spacer is NOT a major intake design change, and it's effects would be mostly insignificant. I would guess that if you had a stock motor and the only change you made was a throttle spacer... you would see no change on a dyno. On a car that is better modified, and is in need of more air.... or more velocity, you might get some gain.... but again, very very little. I think any tuner's money would be better spent on a host of other upgrades... but if you really want one, it won't hurt anything.

 

poop.

 

I can't say they don't work for sure cuz i don't have one on my car but i have heard that they are most valuable on higher displacement engines such as 4.6+ ltr V8's. I personally would never buy one for my car unless like above said i was to upgrade the cam and valves.

am i suppose to be impressed? &lt;---that's a question mark

you can drive a spaceship for all i care that doesn't mean you have a clue as to what you are talkin about. and to top it off you don't even have a tb spacer. so what is the relevance of bring up your 1/4mi time? need an ego boost?

mightly sure of yourself are we? you sound like a noob out of physics 101 class in highschool. Like i said do some REAL tuning, and dyno testing, then talk from experience instead of textbook racing.

the real problem is, YOU shouldn't assume what I do or don't know. I guess it never occured to you that I might have worked at a dyno facility and had a dynometer at my disposal has it?

and that is, "what i got"

 

accords suck anyway.

 

passive bolt on widgets are just that....

Kinda like High flow air filters.

 

i heard it makes ur sig with mods look longer.

 

accords are slow. give up.

 

i daily drive a 12.38 second car. everything im going to say after this will HAVE to be correct.

throttle body spacers are good...........for nothing

theres already a bunch of people who chimed in and said they dont do ****.

 

dyno it and problem solved


and accords suck too

 

Eddie is the WINNER!

 

throttle body spacers were deeloped to be a baind aid for poorly designed manifolds on stock low tech egniens over 30 years ago.
just because it worked on a v8 with a crappy manifold that made 170 hp stock doesnt mean it does a damn thing to a honda that makes MUCH more power per cubic inch.

 

whats the prize for winning? a 12.?? sec car? all over a spacer..i think 97lx got more than he bargained for in this thread

 

All I could see one doing is the same concept of a tornado but after the flap so it might be effective. For those of you who don't know what I'm talking about, a tornado is a useless product that is "suppose" to spin the air into your engine and into your combustion chamber thus making a more thorough burn, but they don't work due to the airs "spin" being stopped by your throttle body's flap. So I could see a throttle body spacer working in terms of spinning the air into the combustion camber and making a cleaner burn, but as for the whole intake manifold size it might be better just to stay stock if your engine is stock (a cai, header, and exhaust does'nt classify your engine as not being stock because it still is). Here is a throttle body spacer and the "Spin" effect that I'm talking about.
http://www.jcwhitney.com/autop...10101

btw even if they do work, it would only be for n/a cars.

 

i do not beleive "spin" will worka t all with a manifold of the design that we have on our hondas.

as far as making the plenum and intake tract longer with a throttle body spacer....how much can an aidditional ONE INCH make when you already added a cold air intake that added 30 or more inches to the intake tract?

 

all of these spacer sellers such as obx show these dyno graphs next to their product that say 40hp increase n **** like that...welcome to the world of bs.
