    Default throttle body spacer

    What exactly does a throttle body spacer do performance wise?


    waste of money or not?

    I have not used one, but I have heard that they give an increase of power on a TBI engine, but not on a multi-port fuel injection engine.

    A friend of mine put one of the ones with the groove cut into it to make the air swirl more on his Dakota. He said it made more power, but it made a whine like a turbo does. He took it off after a while because it drove him nuts.

    I pput a TB spacer on my 87 Blazer and that plus a chip woke it right up anb boosted performance. I never figured mileage on it though. I would however recommend installing one.

    Thanks Man...I have been on the fence about getting one for my 1995 but I didn't see anyone saying that they actually work.

    What about the whining sound? I have to admit my hearing isn't that good. I probably wouldn't even hear it. I think I am going to order a Helix Spacer. Which one did you use?

    You know you got me thinking about this .....and frankly I didn't really put much thought into the idea, however, I started looking for a spacer for my 95 2500 Suburban 4x4 7.4 TBI. There is no listing for that model.
    They have a listing for the CK Pickup 7.4, but the carb numbers do not match.

    Any idea's why????

    Is it the air cleaner spacing?

    Computer make-up

    ?????Any Help
    Thanks

    Mine was a Helix and I purchased that plus the chip through JC Whitney. I think was are sponsored through them and get a discount if I'm not mistaken if you go through the link on our web site.

    As far as the whine or whisteling sound, I only heard it every so often but it just made me feel like it was doing what it was supposed to do by creating a turbine or cyclone with the air/gas mixture causing an increase in performance.
