I am going to try using a KnN filter and see if its passive enough. This current Evolution would be the perfect machine for this. But its already set up and we can not put much more time into it. I have a lot of run hours on it from its previous revision with the older controls and Predator twin. It was very rock solid and made really good gas. This machine now has the Liquid cooled Kohler and the new controls.
I just fired this Kohler up today on gasoline for the first time. This is the first Kohler Aegis we have had since the one we built a few years ago. I absolutely love how this engine sounds, especially just idling. It has this wild cam sound to it and rumbles better than a Harley.
I am now on the final stages of setting up the controller. I can get it to fire up the reactor, move into flare mode, it will auto light the flare and then it will display when everything is to temp. Unfortunately I cant get much past this as the batteries I have are shot. All good ones I had are in the battery bank!! We have been low on funds for the last week, but a new round of funds should be available as soon as tomorrow. Im going to get the Harbor Freight Big daddy of chargers first thing.
During light up of the reactor it is pulling nearly 50-60 amps during pulsing of the igniter plugs. This is firing all of them at once. Next machine I am not going to do this and fire them one at a time. This will require a controller to do so. So this will have its own separate control box. So that should help.
But today it cycled through everything pretty fast; it is a pretty cool machine.
