Hmm, using their calculator, it would take a TBI,(2 injector) 257 gallons per hour flow rate! A MPI system,(8 injector), is 'only' 64 GPH, still quite a bit considering most injectors flow 24, 36, 42,(extreme outputs) for gas so having said all this, I am going to need a huge fuel system that is anodized completely or Stainless Steel lined to survive the corrosiveness. However the benefit I keep seeing are the clean burn and high comp ratios and it's fairly cheap but the fueling stations are not consistent with the ratio of alcohol to gas, thats why the O.E.M. uses the fuel ratio sensors I assume. Without the sensors, and using different ratios would induce lean conditions. And we all know what happens to lean high out put engines!
