How large is too large for GEK?

that link indicates that a larger hearth (in the stock shell) should run a ~40 hp engine (or, in your case, let you pull ~40 hp off your larger engine, without working it too hard/fast.)
Here' the larger hearth in a post about the reactor size being shifted up:

Maybe I am a bit confused but isn't the power pallet running a 3.0 ltr. GM vortex engine at 1800 rpm? On the GM web site the engine is rated at over 60 hp at that rpm. the graph I have is a little hard to read but it looks like all the different fuels show more than 60 hp. Now they don't show what wood gas would be so you would need to deduct for that but even if you take away 30% it would be 42 hp. I am building a 3.0 liter toyota engine which is really strong and shaving the head to raise the compression to about 11 to 1 from the stock 9.5 I hop to run it with the TOTTI with the 4" throat and run a 30 kw or 40 hp 3 phase motor as a 4 pole 1800 rpm induction generator for grid connection. I am pushing the Totti to it's limit because the power company here in the Cayman Islands will pay 44 cents per KW with a 20 year contract. If the Totti can't handle it I will downsize to a 30hp motor and produce 22kw 3 phase. I hope that the 20 hp they are talking about is a conservative estimate, and when I see a car running on a gek I assume it must be.

GM's engine is probably capable of 60 hp on natural gas or propane, but you must derate for the lower power density of wood gas and you must take into account the generator's efficiency. Your car is rated for a certain amount of horsepower too, but you don't drive with your foot to the floor even 10% of the time.
