actually NASCAR V8S are about bang on that figured... unrestricted they run 800hp. thats 137ish per litre...... 1200cc 165hp, 137 per litre....
a sprint car engine eh..... i can belive that. maybe not the price though.... a new weber would chew up all ya budget!!
and methanol.... you need twice as much methanol as you do petrol. and you need a dedicated alcohol fuel system. thats tank, lines, fuel rail, pumps and carb
