I used high temp silicone to glue the seals onto the frame this helped the heat stay in.

Step 26: Insulated Machine Ready to Run

I used a 1750rpm motor and a 50:1 gear box , the unit is heated by a diesel space heater that brings the internal heat to 400 deg F in about 10 min .

Step 27: 50:1 Ratio Motor and Gearbox

Very impressive!
What do you make the molds out of? I presume with the bottle, you started with a pre existing bottle (Header tank?) as the positive?
This could be useful to leverage 3D printing to make things like elaborate plastic inlet manifolds - and many other automotive components.

Wonderful, amazing. but still require more details like how much hp motor, and which company made greabox, wiring and all that stuff. But still amazing. Thanks a lot.
