They know that running that high of nitro hurts there engines but they don't care because they want max power and the only way to get that is with increasing nitro.
These guys run JP's, Rody Modifieds and other engines costing about $900 US! But that still isn't enough power for them so they ram lots of Nitro in there to make the power they want. If you have ever seen a cooling head on a drag race RC it looks really funny. Usually one or two fins.
But the engines run cool enough between the nitro and the amount of run time they see.
Talk to you later....
This is very interresting, Supermaxx, please dont get angry as this is a great way to swop knowledge and it helps us all round.
The reason they have such small heat sinks is because they need to get the temp very high for the nitro. Nitro combusts at much higher temperatures than methanol, and generally burns slower, but I am sure that at high temperatures the nitro makes god power.
I didn't know the drag guys used a different fuel, i have not had any interest, so I never checked.
Have a look at this
I am sure you all will find this VERY interresting, it is to do with aeroplanes, but the baseline is the same. I am sure this will explain better than I can.
