Thanks for the replies.
I have a little Nissan Sentra that I have been able to pull 42mpg out of on a daily bases.
The point in all this was for fun trying something outside the box on my daily driver and hunting/pulling truck, I have other toy's for the hp gpm (yes I put that in right) I just wanted to try something different. But I think I will let this thread die and look another way.

I do want to thank your all for you ideas.

RodStRace: I like the stacking in your shop wish I had one in mine.
