This is another useless modification. I bet a ground-wire kit will have a more positive effect...bwahaha.

These spacers were designed with a HELIX and with the help of a TAPER for 2 reason. Tapering the of bore adds more pressure like the nozzle of an air gun or the nozzle of a water hose. By adding the taper and helix together on this particular part, the air is better guided by the helix directing it into the runners of the intake manifold. This will force the air to compress more, while forcing the incoming air to move forward and outward. Spreading it throughout the the entire intake manifold, without having to turn the 90 degree into the runners. The taper also helps catch more air as it passes through the helix. Giving you a faster air delivery and power.

There you will see all the feebacks for the one I made for the sentra. I know the sentra and the scion are two different cars, but here you will see that it does prove gains.
BTW, Testing is going to be done by Shawn at Church Automotive Testing in WILMINGTON CA. I choose Shawn because he is a very knowledgeable guy, whom shop has appeared on many Import Magazine.

You need to send one to us here on SL and let the skeptics take a few dyno runs with it... I'd love to take a shot at getting anything out of it with a few cars here...
If I can get hp out of it on another local tC here, I'm sure you'd sell a few more... expecially cause I have nothing to gain, as I'm F/I and don't need it.
I'd give it a fair shot.

Please no more response until post up the results.

And in response to the underdrive pulley comment, I disagree. Underdriving the crank pulley >does< something. This spacer is nothing different than a set of grounding wires or a damned turbonater.

I know an underdrive pulley >does< something. I have one. You must not understand what i meant....The thread is filling with arguements about if a TB spacer would provide gains. Its starting to sound like people arguing about if an underdrive pulley can be damaging your engine.

I say just let me take a few stock tCs up here to my dyno shop and we'll give it a fair shot and see what happens... It's an easy, easy install and might not even cost me anything to run...
I can't see many other reasonable solutions to the dilema outside of one of the SL veterans really giving it an outside perspective and test-shot.

^^ I had one in my Eclipse before I realized it really sucked. I think the logic behind this products are,
Obstruct the air path to the engine enough that the ECU sends less fuel and VOILA better MPG! I see it like that.

The smoother the flow the better after and before the TB. This way it flows through the manifold. Only time you want air disruption is when you are running alcohol and it will mix better with the air and ignite, however this is at the head/injector area.
I have made these, just no for the TC. I incorporated several ports around the spacer itself for Nitrous, or any vacuum line you may have ie FPR, Boost, Wastegate..etc.
The horsepower is not incredible, but depending on your application it can work.
