I was just wondering if anyone has done this. I know it would improve throttle response.
The stock rubber bushing all the way at the top of the gas pedal is about an inch long. And when you press the gas pedal down you will see that it compresses the bushing quite a bit. But to replace the bushing with a brass or aluminum one would not allow the compression. I know the stock bushing is there to allow relief of tension in the throttle cable all the way up to the throttle body. But with proper alignment I think this would improve throttle response quite a bit. Just like how they make replacement aluminum shifter bushings to improve shifting response.
I might run a simple test on this. A little fabrication might be in order.

I think this would be a good idea

Good observation, the therory works. Most of the people make the adjustments on the actual cable at the intake manifold fixture but definately you brought up a good point.

Please let us know the results if you decide to test on your own.

Thanks!!

Try it and let us know how it goes. I for one am interested.

Yeah I already made an adjustmet to the cable up on the intake manifold after I had drove the car for 5,000 miles, All new cables will stretch after a while. But replacing this part should show greater throttle response.

I am already almost done with the fabricated piece.

Very interesting topic, subscribing to see results.

Here is a diagram of the piece that I am making.

Would the solid piece have to be shorter than the rubber bushing or would you just loosen the cable at the TB side? Otherwise I think you might end up stretching the cable because without the bushing compressing you are pulling the cable further than normal when you floor it. That or instead of flooring it the pedal would be stopped by the full extension of the throttle cable.

Adjustments will be made at the intake manifold, after installing this piece, the diagram shows that it would be 1" inch, but it will be more like 3/4" Just a little shorter than stock. Everything else will be adjusted to tune the pedal so it wont get to much tension.

Pretty cool idea .
