*Official* Smacks Booster Results Thread
I'm new here, so forgive me if this is a bit of an indulgent thread, but I really would like to see a series of threads dedicated to results on a particular design. In this case, I would like to open this thread for anyone using the Smack booster design for HHO injection.

I've downloaded the plans and I'm considering building off the smack's plan, so I'm really curious what real world results folks are seeing with this design. Please post the make, model and year, your catalyst and your before/after mpg. Also, to help others, if there are any tweaks you've made to the stock design that have proved worthy, please share them.

RE: *Official* Smacks Booster Results Thread
Ive got the plans for the smack booster built it and run it in a 2000 chevy Z71 5.3 vortec engine. Sorry no results yet havent filled up yet. on the last half tank mileage looked about the same maybe worse. I am researching an EFIE but havent selttled in on a design yet. I have run the booster pretty extensively havent yet measured the output accurately. but im certain that it will be in the 1.2-1.7L Per minute range. will update thanks for the thread.
Oh yeah pre booster mileage 16MPG on a good day.

OKay-
I'm running my Smack copy for the 5.7 HEMI along with a dual EFIE.
Still tweaking watching, and playing.
On my last fill up I'm realizing approx 2.7 mpg beter now than before installing anything.
It seems that most are running these on smaller engines, I'm gonna pair it up or build one that can produce more for the big V-8.
Have fun with it Smile

I have been running my smack for a month, no mpg increase. I have a efie and resistors on cts & iat sensors, no cat. Don't know what else to do.

You guys with V8's should have 2 cells connected in series to cut down the heat.

Due to its series design, I'm pretty sure the Smack booster needs the full 12-14 volts to be an effective gas producer.

I realized after posting that you'd probably have to drop out a few neutrals. But then I looked over the plans and you have 2 sets of 3 cells so I think it'd work fine.

It's actually two sets of four cells, or as I recently heard someone else explain it, "two series cells wired in parallel".

There's the + on each end plate - in the middle.

Jk, 6 cells is considered optimal. So if you pull a neutral pair off each side it'd run cooler and should be more efficient since you'd be closer to a true series design.
