Larry, your right. If you want to built an engine for lots of power alcohol would be better.

In the netherlands is driving a car really expensive. So if you can save some money.....and run your engine on lpg ;\)

Holland is FLAT \:D so you can drive everywhere, and you can find lpg everywhere. So we don't have to worry about that.
The gasoline in the netherlands has a octane of 95 and 98. So if you built an engine for lpg (10:1 CR) you can still run on gas if you want without any pinging or what so ever. Even higher CR's a posible with gasoline.

In holland we pay:
gasoline (95) 1.50 euro a liter (7,87 dollar a gallon)
LPG 0.50 euro a liter (2,62 dollar a gallon)

What octane has your gasoline in the US??
I've read a few times that you can't get any higher like 9.0:1 with regular gasoline???
