found this on ebay yesterday....Ive never heard of any 2nd gen people running it. any gains at all? is it worth it? can you use it w/ an aftermarket TB?

They dont work with our cars because how it mounts. Ive had one on a few of my cars and I think they only really work if used on trucks. My jeep seemed to react to it but none of my others did.

I saw that part, but then I thought that the engines are similar, so maybe it would work

just bored and thought id try to post something new and learn something

i know some SRT-4s run TB spacers..

Thats because the tb mounts on the intake. A spacer gives the air time to swirl before entering the manifold. We have a pipe between ours so there is no use.

^thanks for the explanation

so... would it work if we mounted it between the bellows and the manifold?

No there is no need for one. It is only for cars that the TB mounts directly to the manifold. It would basically be a waste.

would there be any gains in putting a longer pipe in place of the bellows tube?

That Im not sure

Yes and no. The simple explanation is that by making the air's path longer or shorter on it's way into the manifold will actually affect performance down low or up high, similar to lengthening or shortening the runners on the manifold itself.

You will see some gains in the upper RPM if you remove the bellows tube and mount the TB dirrectly to the manifold. As our stock manifolds are too long from the factory and this results in a crappy top end performance. This was done to try and improve the lower RPM. This is the reason for the custom manifolds having the 90 degre bend in the runners shortened or even removed compleatly.

I fail to see the need for this on 1st gens even. The air going past the TB has to take a 90 degree bend before it can enter the plenum, then it has to take another 90 degree bend around the runners, then get past the injector humps before it can get into the cumbustion chamber that should provide more then enough turbulance.

Needless to say a TB spacer on a neon is not worth anything...

the bellows tube is basically the tb spacer in our cars. Whether a longer one would make any difference is pretty simple to figure out. the gain is probably the same as most bolt on mods on our cars (and most newer 4 cyl NA cars, for that matter): little to none.
