i could do that but you see i'm a hotrodder at heart. it's not just about how much mpg i can gain from the unit, but how much power i get out of it. you see i'm wanting something scalable since stage two of our build is going to ential a v8 transplant that we will want to use the reactor in. so i figure i'll buld it right the first time and get the bugs worked out of it on the little 1.6 that's in there now and then when we drop the v8 in there it will be a simple job to boost production for the 5 - 6 liter motor that will be taking the place of the tiny 1.6
besides if i built one that was just adequate i'd have to keep fighting the urge to build one that is bigger and better. you're right though i could get by with a much simpler system... and if i was just trying to save a few buck at the pump i'd be doing it as cheep as possible. but this is more of an endeavor to building the best damn reactor i can fit in to that tiny ass car.
