I haven't, but they claim it makes more horsepower. I can't see how atomizing the accel pump shot has anything to do with the power an engine makes at full throttle. Seems like snake oil to me. I wasn't willing to drop the $$ to find out.

Make your own. It's just a piece of metal used to break up the stream. Like spraying a water hose on a window. The water spreads out into smaller droplets. Same thing here, it seems like. You could easily cut out a piece of thin sheetmetal, bend to shape, and put over the nozzles. Presto!

It may also function as a shooter antipullover device and or
Effect fuel distribution in the manifold which can improve wot power if needed.

1982 in my votec electronics class I had a buddy named Smitty with a 340 Cuda and a 750 Holly dp. I remember the 4 squirts of fuel and I thought, "Is that really the best way to do that?" I checked out the pump shot jet setup on my one barrel Holley in my 1968 4 banger International Scout and out of another carb I changed it to squirt more of a mist but made no difference that my butt could feel.

Another great product for the "pulls harder" "revs faster" "spins further" crowd!! Butt dyno enthusiasts worldwide must be ecstatic about this great product!

Some Rochester 4Jet carbs for early-mid '60s Chevys have four accelerator pump discharge streams, two in each primary bore, one down the venturi that targets on the side of the booster and one that shoots nearly horizontal and sprays on the choke blade. Some Rochester B 1bbls for 216-235 Chevy have two streams, one hits the booster and the other aims down the bore avoiding the booster.

Imagine if you teamed this gizmo up with a Tornado!

The Holley clip would be more convincing if they weren't blipping the throttle twice as far in Blaster mode. A throttle stop would be a pretty basic element of a meaningful demo...

you'd need a G suit.

The car will gain 100hp and get so much better mileage that it will actually make gas... but wait, there’s more!!!!

For a certain amount of time the accelerator pump shot is going to impinge on the back of the throttle blade anyway, then dribble across and leave at the edge. What was atomised becomes liquid again when it hits the throttle blade. Even what comes out of the booster venturi has this issue at part throttle, so I don't see it doing a lot of good while the throttle is in the way. At wide throttle openings, just maybe...

The shear plate hangs over the edge of the venturi. Seems that might affect the smooth airflow into the venturi, cause turbulence & affect fuel metering from the booster.
