A Montana outfit thinks they have the secret to inducing lean burn on <2005 cars.
 
What We Do

This outfit thinks they know how to induce 18:1 lean burn with emissions improvements (including reduced NOx somehow) using an aerodynamic device in the throttle body.

The Gadgetman Groove by another name.

Idiots. Almost all intake manifolds for EFI are "dry"; fuel is injected adjacent to the intake valve so their "turbulence" does little or nothing. And for the throttle-bodies I fail to see how this would help either.

I don't think so.

Yes, idiots absolutely. It's a pretty sh!t little piece of kit. It won't do what's claimed. Surely, if the concept works, a rifled wall behind the TB would be even better. But it's not likely to work.

Unicorn corral here we come.

Yeah, it's pretty much bull****.

Are you sure this should be in the unicorn corral? I am pretty sure he wouldn't make up the part about the "complete elimination of noxious gas emissions".

And everyone knows that Q-jet carbs can't be turned upside-down like Holley's and Edelbrock's :D

It may eventually induce a lower fuel amount to be injected, but since that device is a restriction to the airflow I wouldn't call it lean-burn.

Fairly sure it's a DE-restriction, at least from what I've seen...

I haven't seen much about it, but anyway, as long as such de-restriction could cool down the intake stream it might then lead to a leaner burn without an increase to NOx emissions. But it would still be impossible to eliminate NOx at all.
