How about a nitro burning gasser? Street legal!!
I once considered using a water injection system that was operated off a throttle position switch to feed nitro at something over 3/4 throttle. My neighbor was a manager at a plant that sold nitro and said he'd get it for me cheaper. But then he told me the nitro evaporated quickly if not in a sealed container, so when I wasn't using the injection system the nitro could simply evaporate away! That helped make up my mind and I dropped the idea.Wow that is expensive. Maybe we could hook up an IV drip line for injection. Then it would spread the range a bit.
Hows that for crazy?
