Thanks for all the feedback, it helps.
AS to the fuel cell size, you are probably right about the size, so it is going to be 5 gallons or so max. That should last almost forever even if i was constantly hitting the bottle.
And 100 ocatne may not be "race fuel" like you say, but i figure it should be high enough octane to prevent detonation at the power i would be running.
The weight should be offset by the fact that i am stripping the interior down to the two front seats and the dash along with anything else i can pull of htat won't look to obvious.
As for toulene, i really don't have the experience to know about that, and living in the second highest meth county in the country i would be in jail in a week.
Keep the feedback coming.
