X64v Posted May 23, 2008 Share Posted May 23, 2008 Just how incompatible are methanol and aluminum? All the searching I can do on the net says that methanol will slowly eat away at aluminum (unless it's hard-anodized), but in the Nitro R/C world, aluminum is used in fuel systems all the time (fuel filter bodies, carbs, engine blocks, etc.), and Nitro R/C fuel is 60%-70% methanol. I have R/C carbs and fuel tanks and the like that I've used for years and the aluminum looks fine. I ask because plumbing a water/meth injection system would be a lot more inexpensive if one could use normal aluminum AN fittings instead of hard-anodized or SS fittings.

m4xwellmurd3r Posted May 23, 2008 Share Posted May 23, 2008 I think all RC parts are hard anodized whether they look like it or not (clear anodized) otherwise they would oxidize VERY fast. especially the engine components (like carbs) Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted May 23, 2008 Share Posted May 23, 2008 Well, from experience I can tell you that if you leave it in fuel bowls for say over the winter, it'll eat the crap out of them. Fuel fittings are hard anodized already and I've never had a problem. I don't leave alcohol in my fuel system longer than a day unless it's a 2 day or 3 day event. Just my opinion.

Challenger Posted May 23, 2008 Share Posted May 23, 2008 The rc carbs are anodized. Quote Link to comment Share on other sites More sharing options...
X64v Posted May 23, 2008 Author Share Posted May 23, 2008 Alright, thanks guys. I know tons of the rc parts are anodized, but I never knew they were hard anodized. Quote Link to comment Share on other sites More sharing options...
