Hello,

I was wondering where I could find out about how a nitro r/c car engine works. Basically I am thinking of doing a chemistry practical for school (IB extended essay), where I would add things to the fuel to see how it changed its performance. First I was thinking of changing the ratio of castor oil : nitromethane. But I would also like to add some contaminants also; maybe sulphur/dirt/others. But I don't want to screw up the engine. If anyone can think off some things I can add without it killing the engine, or has any ideas about this, I would be grateful. Even if you can just link me to a website or two it would be good. I've had a look around on google but it all just seems like people trying to sell stuff. My msn is [email protected] if anyone is free to have a chat about it.

Thanks,

Sai
