Who has made one?
searched but nothing turned up.

even if you were posting pics of one you made....this isnt advanced fab...... it requires a hunk of aluminum, a tb gasket, a drill, a 1/4" drill bit, and a 58-65mm hole saw

So how thick of a chunk of aluminum? This is a question that I have thought of too. I realize the ease and simplicity of making one. The question that I have however is, what role does the thickness of the "chunk" have. In other words, say thicker versus thinner. What difference is there. I am sure that the differences that will be made from the various thicknesses are prominet. Mpg, idle, responce, hp????

use the search...
after reading all the posts on throttle body spacers, you'd know that you get 5hp and 2mpg for each inch of thickness. Throttle response is improved, no matter what the thickness and the idle is always smoother. Making one 6" thick should therefore give you an increase of 30hp and 12mpg.

spacers dont do anything.........
a longer intake will give you more low end, less high end. You wont see a gain, you wont see a loss, over all, its the same
a 1" spacer will give you prolly a 2 lbft differnce, +2 down low, -2 up top....basically unnoticable. Chrysler had a car (and i cont remember what one it was now) that came in a track and street version, track had short intake runners, street had long, REAL long (like 3 feet) runners. The street version made WICKED low end torque

I think it was called "cross ram" and i belive it had two four barrel carbs.:flame:

Be carefull. You've heard of, "too much of a good thing...", right?jeepdeepfreak said:
I fabbed a TB mounting flange for the top of my snorkle with the snorkle running directly to the intake.
Great for water crossings but I've gone through 4 sets of tires this year and it's hard to leave a stoplight without wheelying.
Plus, I now get such incredible gas mileage that the tank actually keeps overflowing as I drive.

that's an interesting way of mounting a throttle body.
You could potentially break the back of OPEC
You'll be famous for the "kid4lyf broke back mounting"

thats the one
1. The tunnel ram effect is the distance from the value pocket to the intake chamber under the carb or TB. Unless your talking a true IRS. So a spacer under the TB upstream of the intake chamber will have no effect on tunnel ram.
2 . Spacers got there good rep from the OLD days of small carbs on top of small chambers. A spacers would increases the volume of the intake chamber. This could make a small carb "look" bigger to the engine. Also it could improve a turbulence problem of air/fuel trying to make very sharp turn into a very small chamber of many stock intake manifolds at high RPMs.
Today's engines run much larger FI TB bore then the old carb systems would. This tends to cancel out much of the improvement of the spacers under a small carb.
Also because to days system are dry. They no longer need to keep air/fuel speed up in the system to keep fuel suspended and some run much larger intake camber(s) and runners. Because of these changes the spacer is almost dead meat. But the spacer can still fix turbulence problems In poorly. design intake systems
The early FI manifold for the I6 was one of the biggest hack jobs I have ever seen.
More later.

Do you think the spiral made into some really does anything?

No. That's another carryover from "wet" manifolds - with FI, there is no need to keep fuel in suspension (except with TBI - but that only applies on some early 2.46L engines, for us.)
You're actually going to be better off trying to maintain non-turbulent airflow through the intake runners to maximise intake charge volume. With port injection setups, everything upstream of the intake valve is "dry" (the intake valve itself is usually "wet" in order to keep it cool.)
