water-methane injection
for boost yes, if you are N/A, not worth it. I talked to hemifever about it and he said that for the 4.7 there is only so much your can advance and see a gain in HP, the methanol wont do anything other than keep the engine clean, for N/A that is.
hemifevers email:
The timing that these run already won't give you but a few more hp getting more aggressive. Advanced timing doesn't always mean more power with every config. Cams and heads will generally respond to more timing before a stock engine would. but no, I don't have any body messing with meth injection to get more timing on stock n/a engines. It makes a ton of difference on diesels but some folks have done it and not gotten rave results.
