Finally an engine update for you. We have some exciting stuff and it is way past due.
First - we are bringing our pricing back down to about where is was, $1,850 for base engine and $2,475 for the Melvin package (engine, water jacket, and firebox). We're still at least 60 days from order for delivery, in the best of cases.
Second - Power is up - broke 150 rpms = +400 Watts gross power (unpressurized).
Third - We're opening up the engine specs for open source access (see details in the catalog).
