I am experimenting with HHO too. Energybuilders.net is a good source. I put the tube with the HHO gas right into the intake manifold because of the lack of vacum. I didn't see or hear any improvement. I'll keep working on it.
How about this e-turbo. Honeywell, John Deere and others have made one. Bascally an electric motor is set in between the compresor and exhaust sides of a turbo.
I am going to put a greensteamengine on my IDI. It will take the waste heat and turn it into electricity for the HHO kit. Plus I am going to put on a driveshaft alternator. I will also have about 7 batteries on board.
