Yes but I have seen many Hit that number at the races!!
That is why most people replace the engines in less than 1 gallon of fuel.
My stock O.S..18 in my TNX has about 3.5 gallons in it and I can still hit 41mph.It runs about 220 with 30% nitro .
My poor Sportwerks had almost 3 gallons of nitro untill my crash.
I would have to say most people put O.S..18tm in there Traks cars and trucks.
