From the first day my collegue said he wanted to run nitromethanol and i initially said no way!
But after some reading about it i have chanced my mind, it is possible to run some nitromethanol it seems. It is also legal by the rules ofc. (no fuel restrictions)
After some discussion back and forth we have come to the conclusion that running a normal gas engine with either a separate nozzle for the nitromethane with manual activation, or with a extra carb (two in serial) should be a doable solutions.
The reasoning is that by running it dominantly as a gas engine it will not so easily run lean as the petrol part is allready tuned in without the nitro.
Running it as a petrol engine will ease the start up and we can engage the nitromethane separately.
We intend to run RC fuel as it has the oils needed and all that.
I am however a bit confused to how to tune to it. My initial idea was way less compression and very rich mixture as well as a very open exhaust system to avoid any form of missfire.
Another thing if we get real serious is that the ignition needs to be way in advance as the nitro burns slowly.
Any info and some thoughts about this is allways appreciated.
I guess the first question would be: how much nitromethanol? For starters so that there a noticable bump in hp. (We can not mix it directly in the tank it seems as the nitro reacts with the hydrocarbons)
Info about and where to buy toulene, acetone, Propylene Oxide and castor oil would be nice.
