I don't trust the O.S. line of motors because their quality control isn't the greatest. One engine could last you 1 gallon and the next could last you 13. So I wouldn't want to spend about $500 for the speed version and have it blow in a gallon

Novarossi engines are great on quality control, power and fuel economy.
Novas are great and so are the Speeds. I have a Speed that has 12+ gallons through it and another with around 8 both motors are still strong. The one with 12 I finally got tired of running and rebuilt it. The rod had barely worn.
What vehicle are you running? What kind of power do you want? I would throw this question on the Pro Twister mods thread and see what he says...
