HI mhamilton31,

No, wish I did but it was close to 15 years ago. All I have left is a pic of the plane showing the NACA vent that fed both my AeroCarb and my oil cooler.
I have cold air induction on my Onex but it has a Zenith carb, which needs carb heat, which made the installation much more complicated. The pics explain what I have now.
All you have to do with the AeroInjector is build a box around the inlet, using the air filter flange as a starting point, and pipe fresh air to it. I did install a larger K&N filter. The factory warns against ram air at the inlet so feeding the carb from a side mounted NACA is probably the way to go.
If you want an explanation of how to build the box, I can offer words but that's it.
Oh yea, I have to add this "fine point". Remember that the AeroInjector will continue to leak fuel with the engine off if fuel is left on and the mixture isn't pulled to idle cutoff. On my Sonex installation the airbox sloped from front to back to clear the cowl bottom. I drilled two #30 weep holes in the lower corners so that if I forgot to pull mixture I wouldn't end up with an airbox full of fuel. Sure enough, I called the guy I sold the plane to and caught him at a fuel stop on his way home. I heard the fuel guy yelling "You're leaking fuel".
One more little thing. I used closed end pops down stream of the air filter. Wouldn't want a mandrel to get loose and sucked through the engine.
