I did not say 30 makes as much power as 16. I might have said that 16 is just as fast on the track as 30 when shimmed correctly. The more nitro will add more power. That is a fact. 16% will have similar top rpm, but the 30 will get there faster, and use more fuel to do it.
With 16% which is what the .12's come shimmed for from the factory you get good runtime, and good power. That is also what is required to be run at the World Championship for 200mm sedans.
With my on road modified engines, there is not much need for more than 16% nitro. We are still roasting the tires off the cars. 30% Nitro will just waste tires, fuel, etc...
For 8th on road if you can afford to lose runtime, use 25% nitro. Most people are using less than the max allowed nitro in 8th on road just to make 5 minutes of runtime. If not they are making a pit stop at around the 3 minute mark.
It is obvious in 8th on road when someone is going to try for 5 minutes, or going to pit at 3 minutes. The 5 minute engine is way slower than the 3 minute fire breathers. The funny thing is that with a pit stop the faster engines are still faster than the de-tuned 5 minute engines. Most of the time.
I also run 16% in all of my modified off road engines. I still have too much power, and runtime for days. It's fun to blow past people who are using almost twice the nitro as me in the dirt, and keep on going after they have run out of fuel.
However, in drag racing 132 feet we use 55%+ nitro. Oh yea talk about instant full power.
Nitro makes power.
