Carb improvement

I think the product has merit, since nearly any fuel stream leaving the pump nozzle orifice gets broken up early and almost as good as the fuel emulsion leaving the booster.

The only time Holleys' intended target of the side of the booster is when the nozzle is pressurised by the pump action, when the pump capacity and cam action is faster than the nozzle flows, so then the nozzle is the timed restriction.

I'd like to see a pump nozzle that sprays closer to horizontal.

The ideal is to have a fuel curve that follows the demands of the engine more closely, and relies less on accelerator pump volume.

When you can tune for an overlapping fuel curve that allows the engine to free rev without the accelerator pump, you are getting close.

The Holley pink cams are high volume, but carry the fuel across some 75 degrees of throttle opening, so are useful to reduce the volume used in the first 25 degrees.

This company has spent the money in R&D, so for the cost of the units, it would be worth a go. I hope they have patented their product to stop the copycats.
