Well I bought an OBX throttle body spacer from someone on here and I must say that I am impressed. The installation was fairly easy (4 out of 10) but the only problem I ran into was the throttle bracket. The cable is adjusted all the way back and it is not allowing the butterfly to close all the way. It is idleling around 1k but it not that much higher then normal. I am going to be making a custom bracket to solve this issue. When you install this spacer, be sure to have extra vacuum lines handy. It comes with a hose (mine didn’t). I noticed a difference just by driving it around the block but once I drive it a little more I will update any other performance differences. I love the way it sounds. It sounds almost like you are spoolin’ LOL. I would say this is a good investment but just remember that it might be a good idea to fix the bracket issue. If you buy one and need help installing it let me know.
Maybe a noob question but what exactly does the TB spacer do? Gets more air into the intake mani?
It is supposed to spin the air into the intake manifold to get a better air/fuel mixture which burns the fuel better thus creating horsepower.
Ahh I see, thanks for explaining about the spacers… I learn something new today! :bowthank:
It was actually a noticeable difference in power?? i wouldn’t think so…at least not that much of a difference…your ears are probably tricking you because you like the sound better.
well maybe but I did feel a difference when I first installed it.
#1 - Idling at 1k is going to eat up gas.
#2 - You need to have dynoed the car both before and after the installation to see if it made any significant difference. I can almost guarantee you won’t be able to feel anything. Butt dynos lie.
The idle is fixed. The butterfly was not closing all the way because of the crappy bracket that came with it. The cable was too tight and adjusted all the way back. So I installed it a different way and now it idles just like before. I think it made a difference but if it didn’t, oh well. I still like the sound of it.
Just a thought provoking question, how does one spin the air-fuel mixture using a throttle body spacer on a fuel injected car?
The answer?
you woiuld have to put the spacer after the fuel was introduced. that mean in between the intake manifold and head.
Spacers were designed for carbureted cars, to be mounted between the carburetor and the runners. In a carburetor the “throttle body” is built into the carburetor itself. The theory is to swirl the air on the outer sides, creating turbulence and keeping the fuel off of the walls. this vortex effect keeps the fuel suspended so you get a better mixture and burn.
In a Fuel injected engine it serves little purpose.
haha…nice thought
seems kinda like a tornado…just fancier.
i had that exact spacer (i sold it to him) and i never got the chance to actually put it to the test so i have no clue
throttle body spacers are only for noise. I had one for 5 months and nothing seemed different. thumbs down…I think they were built for carborated cars.
A spacer like that adds alittle more volume to the intake manifold which could help some motors alittle.
